In order to achieve an optical signal memory device with read–write functions, a topological Su–Schrieffer–Heeger lattice is proposed. It is found that a transformation between a topological corner state and an edge state occurs under the magneto-optical effect. Without an external magnetic field, the electromagnetic (EM) signal is confined and stored at the corner, which realizes the writing process of a signal. When an external magnetic field is applied, the EM signal is released from the corner to the edge, which realizes the reading process of the signal. The result is expected to provide guidance for the design of high-performance reading–writing EM memories. [ABSTRACT FROM AUTHOR]

The article reads The Stone Virgins as a text underlined by an Indigenous poetics that situates the land as a speaking subject and an archive of memory. Its critical foci are African feminist conceptions of the entanglement of human and nonhuman matter and their implications for current conceptions of the archive. The article suggests that, rather than incorporating into the postcolonial national archive the excluded voices of women and ethnic minorities, The Stone Virgins makes legible minority practices of memory making that the archive does not recognize. To account for these practices and their literary representation, the article draws a comparison between the novel's poetics of land and Indigenous poetics across other Anglophone spheres. The comparison is based in the convergence of Black and Indigenous conceptions of the coconstitutionality of the human and nonhuman. The comparison provides a new critical model for reading postcolonial aesthetic formations that engage nonhuman beings. It furthermore speaks to larger conversations regarding the "ontological turn" of criticism oriented to animist and new materialisms, as it addresses a mode of reading the land in African writing attuned to Indigenous systems of knowledge.

Many chemical reactions and molecular processes occur on time scales that are significantly longer than those accessible by direct simulations. One successful approach to estimating dynamical statistics for such processes is to use many short time series of observations of the system to construct a Markov state model, which approximates the dynamics of the system as memoryless transitions between a set of discrete states. The dynamical Galerkin approximation (DGA) is a closely related framework for estimating dynamical statistics, such as committors and mean first passage times, by approximating solutions to their equations with a projection onto a basis. Because the projected dynamics are generally not memoryless, the Markov approximation can result in significant systematic errors. Inspired by quasi-Markov state models, which employ the generalized master equation to encode memory resulting from the projection, we reformulate DGA to account for memory and analyze its performance on two systems: a two-dimensional triple well and the AIB9 peptide. We demonstrate that our method is robust to the choice of basis and can decrease the time series length required to obtain accurate kinetics by an order of magnitude. [ABSTRACT FROM AUTHOR]

Traditionally, physical models of associative memory assume conditions of equilibrium. Here, we consider a prototypical oscillator model of associative memory and study how active noise sources that drive the system out of equilibrium, as well as nonlinearities in the interactions between the oscillators, affect the associative memory properties of the system. Our simulations show that pattern retrieval under active noise is more robust to the number of learned patterns and noise intensity than under passive noise. To understand this phenomenon, we analytically derive an effective energy correction due to the temporal correlations of active noise in the limit of short correlation decay time. We find that active noise deepens the energy wells corresponding to the patterns by strengthening the oscillator couplings, where the more nonlinear interactions are preferentially enhanced. Using replica theory, we demonstrate qualitative agreement between this effective picture and the retrieval simulations. Our work suggests that the nonlinearity in the oscillator couplings can improve memory under nonequilibrium conditions. [ABSTRACT FROM AUTHOR]

The current study examined the acquisition, retention, and transfer effects of a motor program. Children with autism spectrum disorder participated in a 9-week program that targeted 13 fundamental motor skills based upon the Test of Gross Motor Development-3. Assessments were conducted before and after the program, as well as at 2-month follow-up. Significant improvements were found on not only the trained fundamental motor skills (acquisition) but also the untrained tasks on balance (transfer). The follow-up tests revealed continuous improvement on the trained locomotor skills (retention), as well as the untrained skills on balance (retention + transfer). These findings highlight the importance of continuous support and long-term participation on motor practices. [ABSTRACT FROM AUTHOR]

We investigated age-related differences in serial and strategic processing during the encoding and retrieval of high-value words. Younger and older adults were presented with word triads positioned left, center, and right, with one word being more valuable than the others. In Experiment 1, younger adults more effectively recalled the middle, high-value word, demonstrating enhanced strategic memory. Younger adults were more likely to initiate recall with a high-value word whereas older adults were equally likely to initiate recall with a left and high-value word. Additionally, older adults were more likely to recall words in their presented order while younger adults strategically recalled successive high-value words. However, both age groups demonstrated strategic processing in Experiments 2 and 3, even without prior knowledge of the high-value word’s location. Thus, serial and strategic processing may differ based on age and task demands, but strategic processing is preserved in older adults in certain contexts. [ABSTRACT FROM AUTHOR]

In this work, we report on the observation of resistive switching (RS) in the nanocrystalline tellurium oxide (TeO x ) in ITO/TeO x /Ag device configuration. The TeO x films grown in an O2/Ar environment have dominant β -TeO2 along with other polymorphs and amorphous TeO2. From the RS characteristics, it is suggestive that the β -TeO2 phase promotes the conductive filament formation across the highly insulating amorphous matrix. The memory device demonstrates bipolar RS with excellent endurance, retention and on–off ratio. The device also features formation-free switching with low set and reset voltage (0.6 V and −0.8 V respectively) and displays multilevel switching upon varying compliance current. Current-Voltage characterization clarifies the conduction path is indeed filamentary type. The result highlights that TeO x can be a prominent RS material for memory and brain-inspired computing devices. [ABSTRACT FROM AUTHOR]

Numerous prospective biomarkers are being studied for their ability to diagnose various stages of Alzheimer's disease (AD). High-density electroencephalogram (EEG) methods show promise as an accurate, economical, non-invasive approach to measuring the electrical potentials of brains associated with AD. Event-related potentials (ERPs) may serve as clinically useful biomarkers of AD. Through analysis of secondary data, the present study examined the performance and distribution of N4/P6 ERPs across the frontoparietal network (FPN) using EEG topographic mapping. ERP measures and memory as a function of reaction time (RT) were compared between a group of (n = 63) mild untreated AD patients and a control group of (n = 73) healthy age-matched adults. Based on the literature presented, it was expected that healthy controls would outperform patients in peak amplitude and mean component latency across three parameters of memory when measured at optimal N4 (frontal) and P6 (parietal) locations. It was also predicted that the control group would exhibit neural cohesion through FPN integration during cross-modal tasks, thus demonstrating healthy cognitive functioning consistent with older healthy adults. By targeting select frontal and parietal EEG reference channels based on N4/P6 component time windows and positivity, our findings demonstrated statistically significant group variations between controls and patients in N4/P6 peak amplitudes and latencies during cross-modal testing. Our results also support that the N4 ERP might be stronger than its P6 counterpart as a possible candidate biomarker. We conclude through topographic mapping that FPN integration occurs in healthy controls but is absent in AD patients during cross-modal memory tasks. [ABSTRACT FROM AUTHOR]

Superagers are elderly individuals with the memory ability of people 30 years younger and provide evidence that age-related cognitive decline is not inevitable. In a sample of 64 superagers (mean age, 81.9; 59% women) and 55 typical older adults (mean age, 82.4; 64% women) from the Vallecas Project, we studied, cross-sectionally and longitudinally over 5 years with yearly follow-ups, the global cerebral white matter status as well as region-specific white matter microstructure assessment derived from diffusivity measures. Superagers and typical older adults showed no difference in global white matter health (total white matter volume, Fazekas score, and lesions volume) cross-sectionally or longitudinally. However, analyses of diffusion parameters revealed the better white matter microstructure in superagers than in typical older adults. Cross-sectional differences showed higher fractional anisotropy (FA) in superagers mostly in frontal fibers and lower mean diffusivity (MD) in most white matter tracts, expressed as an anteroposterior gradient with greater group differences in anterior tracts. FA decrease over time is slower in superagers than in typical older adults in all white matter tracts assessed, which is mirrored by MD increases over time being slower in superagers than in typical older adults in all white matter tracts except for the corticospinal tract, the uncinate fasciculus, and the forceps minor. The better preservation of white matter microstructure in superagers relative to typical older adults supports resistance to age-related brain structural changes as a mechanism underpinning the remarkable memory capacity of superagers, while their regional aging pattern is in line with the last-in-first-out hypothesis.

Metal halide perovskites (MHPs) are considered as promising candidates in the application of nonvolatile high‐density, low‐cost resistive switching (RS) memories and artificial synapses, resulting from their excellent electronic and optoelectronic properties including large light absorption coefficient, fast ion migration, long carrier diffusion length, low trap density, high defect tolerance. Among MHPs, 2D halide perovskites have exotic layered structure and great environment stability as compared with 3D counterparts. Herein, recent advances of 2D MHPs for the RS memories and artificial synapses realms are comprehensively summarized and discussed, as well as the layered structure properties and the related physical mechanisms are presented. Furthermore, the current issues and developing roadmap for the next‐generation 2D MHPs RS memories and artificial synapse are elucidated. [ABSTRACT FROM AUTHOR]

Two‐dimensional (2D) ferroionics is appealing in performing complex artificial intelligence tasks due to the interesting property of coexistence of ferroelectricity and ionic activities. CuInP2S6 (CIPS), as a typical 2D ferroionic material, is highly conducive to rich functions of information devices due to the displacement of Cu+ inducing both ferroelectricity and ionic conductivity. However, the coupling and modulation of polarization and ion migration in CIPS for multifunctional information devices has not been fully explored. Here, this study demonstrates that digital memory and synaptic simulations are realized in Au/CIPS/Au device via engineering ferroelectric polarization reversal and the long‐distance migration of the Cu+ to change conductive modes. Steep resistive switching behavior based on ion‐migration is observed with a high on/off ratio of over 108, long retention time (>2 × 104 s), and current compliance engineered multilevel resistance states, demonstrating reliable nonvolatile high‐density memory characteristics. Based on the continuous modulation of polar order, the key synaptic behaviors are successfully simulated. Moreover, by the co‐modulation of polarization state and ions migration, the paired‐pulse facilitation, paired‐pulse depression, and potentiation following depression are achieved. These results suggest that CIPS is a promising candidate for constructing high‐performance, function‐enriched devices for data storage, information processing, and neuromorphic computing.

Background: Caffeoylquinic acid (CQA), which is abundant in coffee beans and Centella asiatica, reportedly improves cognitive function in Alzheimer's disease (AD) model mice, but its effects on neuroinflammation, neuronal loss, and the amyloid-β (Aβ) plaque burden have remained unclear. Objective: To assess the effects of a 16-week treatment with CQA on recognition memory, working memory, Aβ levels, neuronal loss, neuroinflammation, and gene expression in the brains of 5XFAD mice, a commonly used mouse model of familial AD. Methods: 5XFAD mice at 7 weeks of age were fed a 0.8% CQA-containing diet for 4 months and then underwent novel object recognition (NOR) and Y-maze tests. The Aβ levels and plaque burden were analyzed by enzyme-linked immunosorbent assay and immunofluorescent staining, respectively. Immunostaining of markers of mature neurons, synapses, and glial cells was analyzed. AmpliSeq transcriptome analysis and quantitative reverse-transcription-polymerase chain reaction were performed to assess the effect of CQA on gene expression levels in the cerebral cortex of the 5XFAD mice. Results: CQA treatment for 4 months improved recognition memory and ameliorated the reduction of mature neurons and synaptic function-related gene mRNAs. The Aβ levels, plaque burden, and glial markers of neuroinflammation seemed unaffected. Conclusions: These findings suggest that CQA treatment mitigates neuronal loss and improves cognitive function without reducing Aβ levels or neuroinflammation. Thus, CQA is a potential therapeutic compound for AD, improving cognitive function via as-yet unknown mechanisms independent of reductions in Aβ or neuroinflammation. [ABSTRACT FROM AUTHOR]

Memory retrieval can become difficult over time, but it is important to note that memories that appear to be forgotten might still be stored in the brain, as shown by their occasional spontaneous retrieval. Histamine in the central nervous system is a promising target for facilitating the recovery of memory retrieval. Our previous study demonstrated that histamine H3 receptor (H3R) inverse agonists/antagonists, activating histamine synthesis and release, enhance activity in the perirhinal cortex and help in retrieving forgotten long-term object recognition memories. However, it is unclear whether enhancing histaminergic activity alone is enough for the recovery of memory retrieval, considering that H3Rs are also located in other neuron types and affect the release of multiple neurotransmitters. In this study, we employed a chemogenetic method to determine whether specifically activating histamine neurons in the tuberomammillary nucleus facilitates memory retrieval. In the novel object recognition test, control mice did not show a preference for objects based on memory 1 week after training, but chemogenetic activation of histamine neurons before testing improved memory retrieval. This selective activation did not affect the locomotor activity or anxiety-related behavior. Administering an H2R antagonist directly into the perirhinal cortex inhibited the recovery of memory retrieval induced by the activation of histamine neurons. Furthermore, we utilized the Barnes maze test to investigate whether chemogenetic activation of histamine neurons influences the retrieval of forgotten spatial memories. Control mice explored all the holes in the maze equally 1 week after training, whereas mice with chemogenetically activated histamine neurons spent more time around the target hole. These findings indicate that chemogenetic activation of histamine neurons in the tuberomammillary nucleus can promote retrieval of seemingly forgotten object recognition and spatial memories.

I defend the view that episodic memory judgments do not depend on any kind of identification of oneself as the person whose past is being remembered, and are therefore logically (rather than merely de facto) immune from error through misidentification relative to “I”. There are two challenges to this view that have been pressed in the literature. One appeals to the idea of background presuppositions of identity and says that “I am the person from whom my memory impression derives” is a background presupposition of any memory judgment. The other appeals to wh-misidentification and says there are possible cases in which memory goes astray that should be counted as cases of error through wh-misidentification. Although the details are different, the core thought behind both challenges is the same: Shoemaker’s thought that there could be a memory-like relation that one stands in to another’s past. I think this thought is a mistake. [ABSTRACT FROM AUTHOR]

Regular exercise benefits learning and memory in older adults, but the neural mechanisms mediating these effects remain unclear. Evidence in young adults indicates that acute exercise creates a favourable environment for synaptic plasticity by enhancing cortical disinhibition. As such, we investigated whether plasticity‐related disinhibition mediated the relationship between cardiorespiratory fitness and memory function in healthy older adults (n = 16, mean age = 66.06). Participants completed a graded maximal exercise test and assessments of visual and verbal memory, followed by two counterbalanced sessions involving 20 min of either high‐intensity interval training exercise or rest. Disinhibition was measured following intermittent theta burst stimulation via paired‐pulse transcranial magnetic stimulation. In line with our hypotheses, we observed a positive correlation between cardiorespiratory fitness and verbal memory, which was mediated by plasticity‐related cortical disinhibition. Our novel finding implicates cortical disinhibition as a mechanism through which the effects of acute bouts of exercise may translate to improved memory in older adults. This finding extends current understanding of the physiological mechanisms underlying the positive influence of cardiorespiratory fitness for memory function in older adults, and further highlights the importance of promoting exercise engagement to maintain cognitive health in later life. Key points: There are well established benefits of regular exercise for memory function in older adults, but the mechanisms are unclear. Cortical disinhibition is important for laying down new memories, and is enhanced following acute exercise in young adults, suggesting it is a potential mechanism underlying these benefits in ageing.Older adults completed a fitness test and assessments of memory, followed by two sessions involving either 20 min of exercise or rest. Disinhibition was measured following intermittent theta burst stimulation via paired‐pulse transcranial magnetic stimulation.Cardiorespiratory fitness was positively associated with memory performance. Higher fitness was associated with enhanced cortical disinhibition following acute exercise.Cortical disinhibition completely mediated the relationship between fitness and memory.This novel finding provides a mechanistic account for the positive influence of cardiorespiratory fitness on memory in later life, and emphasises the importance of regular exercise for cognitive health in older populations.

This study aimed to investigate the synchrony/asynhrony effect on eyewitness memory. Forty-four participants (24 evening-types and 20 morning-types) performed, individually, two online sessions: one in the morning and another in the evening. In each session, each participant visualized two videos (crime and neutral scenes), answered questions related to the videos and completed additional questionnaires. In general, the participants’ memory was better in the synchrony when compared to the asynchrony moment. In the crime videos, participants recalled more central details and in the neutral videos more peripherical details. The pattern of results remains similar when controlled by stress, anxiety, and depression. [ABSTRACT FROM AUTHOR]

The design of a narrative video game for cognitive training of memory and executive functions in older adults with subjective and objective cognitive impairment is reported along with preliminary results on preferences (Study 1), user interaction experience (Study 2), and efficacy of the game (Study 3). A study of aesthetic preferences in backgrounds and avatars was implemented in 13 older adults, who were asked for their opinion on the acceptability of the plot. After completion of the design, a user interaction study was conducted in a sample of 19 older adults. In addition, a Matched Paired Experimental Design (MPED) was implemented as a preliminary test of the efficacy of the narrative video game in a sample of 22 participants with Subjective Cognitive Decline (SCD) and Mild Cognitive Impairment (MCI). Preferences for free violence content in videogames was supported in our sample of low-frequency adult gamers and acceptability of the plot was high. The video game was rated favourably by the older adults in terms of user preferences and acceptability. The results of the preliminary MPED study suggest that the video game could be a useful tool for cognitive training in SCD and MCI older adults. [ABSTRACT FROM AUTHOR]

In their natural environment, animals face a variety of ecological and social challenges, which might be linked to the emergence of different cognitive skills. To assess inter-specific variation in cognitive skills, we used ungulates as a study model, testing a total of 26 captive individuals across 5 different species (i.e., dwarf goats, Capra aegagrus hircus, llamas, Lama glama, guanacos, Lama guanicoe, zebras, Equus grevyi, and rhinos, Diceros bicornis michaeli). Across species, we used the same well-established experimental procedures to test individuals' performance in naïve physics tasks, i.e. object permanence, short-term spatial memory, causality, understanding of object properties, and gravity. Our results revealed that study subjects showed object permanence, were able to remember the position of hidden food after up to 60 s, and inferred the position of hidden food from the sound produced or not produced when shaking containers. Moreover, they showed an understanding of basic object properties, being able to locate objects hidden behind occluders based on their size and inclination, and could reliably follow the trajectory of falling objects across different conditions. Finally, inter-specific differences were limited to the understanding of object properties, and suggest that domesticated species as goats might perform better than non-domesticated ones in tasks requiring these skills. These results provide new information on the cognitive skills of a still understudied taxon and confirm ungulates as a promising taxon for the comparative study of cognitive evolution.

Emojis or emoticons are commonly used to convey emotional status to others in text‐based, online communication. While several studies have investigated the influence of emojis on emotional processing, the influence of emojis on the recognition of messages is less understood. In the present study, we investigated the effects of emojis accompanying a short text message on the emotional impressions and memory of the messages. The results suggested that emojis modulated the emotional processing of the messages; the emotional arousal of the messages increased by adding emojis, and the emotional valence of messages was biased towards the valence of emojis. Furthermore, we found that the memory of the text messages was modulated by emojis; the recognition performance of the positive text messages was improved when they appeared with negative emojis. These results implied that emojis would have an impact on cognitive processing, as well as the emotional processing of text messages. [ABSTRACT FROM AUTHOR]

Memory reactivation during sleep is thought to facilitate memory consolidation. Most sleep reactivation research has examined how reactivation of specific facts, objects, and associations benefits their overall retention. However, our memories are not unitary, and not all features of a memory persist in tandem over time. Instead, our memories are transformed, with some features strengthened and others weakened. Does sleep reactivation drive memory transformation? We leveraged the Targeted Memory Reactivation technique in an object category learning paradigm to examine this question. Participants (20 female, 14 male) learned three categories of novel objects, where each object had unique, distinguishing features as well as features shared with other members of its category. We used a real-time EEG protocol to cue the reactivation of these objects during sleep at moments optimized to generate reactivation events. We found that reactivation improved memory for distinguishing features while worsening memory for shared features, suggesting a differentiation process. The results indicate that sleep reactivation does not act holistically on object memories, instead supporting a transformation where some features are enhanced over others. [ABSTRACT FROM AUTHOR]

Despite the known behavioral benefits of rapid eye movement (REM) sleep, discrete neural oscillatory events in human scalp electroencephalography (EEG) linked with behavior have not been discovered. This knowledge gap hinders mechanistic understanding of the function of sleep, as well as the development of biophysical models and REM-based causal interventions. We designed a detection algorithm to identify bursts of activity in high-density, scalp EEG within theta (4–8 Hz) and alpha (8–13 Hz) bands during REM sleep. Across 38 nights of sleep, we characterized the burst events (i.e., count, duration, density, peak frequency, amplitude) in healthy, young male and female human participants (38; 21F) and investigated burst activity in relation to sleep-dependent memory tasks: hippocampal-dependent episodic verbal memory and nonhippocampal visual perceptual learning. We found greater burst count during the more REM-intensive second half of the night (p < 0.05), longer burst duration during the first half of the night (p < 0.05), but no differences across the night in density or power (p > 0.05). Moreover, increased alpha burst power was associated with increased overnight forgetting for episodic memory (p < 0.05). Furthermore, we show that increased REM theta burst activity in retinotopically specific regions was associated with better visual perceptual performance. Our work provides a critical bridge between discrete REM sleep events in human scalp EEG that support cognitive processes and the identification of similar activity patterns in animal models that allow for further mechanistic characterization.

It is unclear whether memory for images of poorer visibility (as low contrast or small size) will be lower due to weak signals elicited in early visual processing stages, or perhaps better since their processing may entail top-down processes (as effort and attention) associated with deeper encoding. We have recently shown that during naturalistic encoding (free viewing without task-related modulations), for image sizes between 3°–24°, bigger images stimulating more visual system processing resources at early processing stages are better remembered. Similar to size, higher contrast leads to higher activity in early visual processing. Therefore, here we hypothesized that during naturalistic encoding, at critical visibility ranges, higher contrast images will lead to higher signal-to-noise ratio and better signal quality flowing downstream and will thus be better remembered. Indeed, we found that during naturalistic encoding higher contrast images were remembered better than lower contrast ones (~ 15% higher accuracy, ~ 1.58 times better) for images at 7.5–60 RMS contrast range. Although image contrast and size modulate early visual processing very differently, our results further substantiate that at poor visibility ranges, during naturalistic non-instructed visual behavior, physical image dimensions (contributing to image visibility) impact image memory.

Research Highlights The human central nervous system (CNS) undergoes tremendous changes from childhood to adulthood and this may affect how individuals at different stages of development learn new skills. Here, we studied motor skill learning in children, adolescents, and young adults to test the prediction that differences in the maturation of different learning mechanisms lead to distinct temporal patterns of motor learning during practice and overnight. We found that overall learning did not differ between children, adolescents, and young adults. However, we demonstrate that adult‐like skill learning is characterized by rapid and large improvements in motor performance during practice (i.e., online) that are susceptible to forgetting and decay over time (i.e., offline). On the other hand, child‐like learning exhibits slower and less pronounced improvements in performance during practice, but these improvements are robust against forgetting and lead to gains in performance overnight without further practice. The different temporal dynamics of motor skill learning suggest an engagement of distinct learning mechanisms in the human CNS during development. In conclusion, adult‐like skill learning mechanisms favor online improvements in motor performance whereas child‐like learning mechanisms favors offline behavioral gains. Many essential motor skills, like walking, talking, and writing, are acquired during childhood, and it is colloquially thought that children learn better than adults. We investigated dynamics of motor skill learning in children, adolescents, and young adults. Adults displayed substantial improvements during practice that was susceptible to forgetting over time. Children displayed smaller improvements during practice that were resilient against forgetting. The distinct age‐related characteristics of these processes of acquisition and consolidation suggest that skill learning relies on different mechanisms in the immature and mature central nervous system.

Hypoxia in preterm infants is a clinical condition that has been associated with cognitive and behavioral disturbances for which treatment strategies are strongly required. Melatonin administration following brain insults has been considered a promising therapeutic strategy due to its antioxidant and anti‐inflammatory effects. Not surprisingly, it has been extensively studied for preventing disturbances following brain injury. This study evaluated the effects of melatonin on developmental disturbances, memory disruption, and hippocampal cell loss induced by neonatal anoxia in rats. Neonatal Wistar rats were subjected to anoxia and subsequently treated with melatonin. Later, maturation of physical characteristics, ontogeny of reflexes, learning and memory in the Morris water maze (MWM), and estimates of the number of hippocampal neurons, were evaluated. Melatonin treatment attenuated (1) female anoxia‐induced delay in superior incisor eruption, (2) female anoxia‐induced vibrissae placement reflexes, and (3) male and female anoxia‐induced hippocampal neuronal loss. Melatonin also promoted an increase (5) in swimming speeds in the MWM. In addition, PCA analysis showed positive associations between the acoustic startle, auditory canal open, and free fall righting parameters and negative associations between the male vehicle anoxia group and the male melatonin anoxia group. Therefore, melatonin treatment attenuates both anoxia‐induced developmental deficits and hippocampal neuronal loss. [ABSTRACT FROM AUTHOR]

AbstractObjectiveMethodResultsConclusionsMenopause is a physiological period characterized by the cessation of ovarian activity. Sequential changes during this transition affect multiple systems, including the brain. Sixty percent of women experience cognitive impairment. The objective of this review is to show the neuroprotective effect of hormone replacement therapy (HRT) through the different scales and whether there is a benefit of this in women.A search was conducted in six databases. Eligibility criteria included women within 10 years of menopause, receiving HRT controlled with placebo, studies lasting more than 6 months and women without a history of chronic underlying pathology.A total of nine randomized controlled trials met the inclusion criteria. Regarding memory, two studies reported better performance of HRT with a significant odds ratio (OR) of 0.67; regarding attention, one study reported potential improvement in women receiving HRT with a significant OR of 0.87; and neuroimaging assessment found an increase in ventricular volume compared to placebo over a 3-year period.The early initiation of menopausal HRT in healthy women appears to yield a positive effect on certain cognitive aspects, such as attention and cortical volume in the central nervous system. These findings should be confirmed through future prospective studies. [ABSTRACT FROM AUTHOR]

Neuroimaging studies have shown that activity in the prefrontal cortex correlates with two critical aspects of normal memory functioning: retrieval of episodic memories and subjective "feelings-of-knowing" about our memory. Brain stimulation can be used to test the causal role of the prefrontal cortex in these processes, and whether the role differs for the left versus right prefrontal cortex. We compared the effects of online High-Definition transcranial Direct Current Stimulation (HD-tDCS) over the left or right dorsolateral prefrontal cortex (DLPFC) compared to sham during a proverb-name associative memory and feeling-of-knowing task. There were no significant effects of HD-tDCS on either associative recognition or feeling-of-knowing performance, with Bayesian analyses showing moderate support for the null hypotheses. Despite past work showing effects of HD-tDCS on other memory and feeling-of-knowing tasks, and neuroimaging showing effects with similar tasks, these findings add to the literature of non-significant effects with tDCS. This work highlights the need to better understand factors that determine the effectiveness of tDCS, especially if tDCS is to have a successful future as a clinical intervention.

Linguistic categories can impact visual perception. For instance, learning that two objects have different names can enhance their discriminability. Previous studies have identified a typical pattern of categorical perception, characterized by faster discrimination of stimuli from different categories, a neural mismatch response during early visual processing (100–200 ms), and effects restricted to the right visual field. However, it remains unclear whether language affects perception online or through long‐term changes to mental representations in memory. To address this, we tested the impact of newly learned object categories with and without memory consolidation during sleep. We replicated the canonical pattern of categorical perception for categories that underwent consolidation. Without consolidation, linguistic categories still influenced early visual processing but with distinct neural dynamics. Therefore, we found evidence of both transient and long‐term effects of language on perception and conclude that memory consolidation plays a crucial role in shaping how linguistic categories modulate perception.

Memory for what, where, and when an event took place has been interpreted as playing a critical role in episodic memory. Moreover, such memory is likely to be important to an animal's ability to efficiently forage for food. In Experiment 1 of the present study, pigeons were trained on a task in which on each trial, one lit stimulus color and location was presented and then another. A cue presented after the last stimulus location signaled that the pigeon was to choose either the first location presented, or the last location presented, to receive a reinforcer. After learning this task, in Experiment 2, the color cue was removed, requiring the pigeons to choose based on location and order alone. In Experiment 3, when a delay was inserted between presentation of the two locations, it had little effect on task accuracy. Results suggested that the pigeons had acquired the task using a single-code/default rule. When presented with the cue indicating that the last location was correct, pigeons selected the location just presented. When presented with the cue indicating that the first location was correct, pigeons chose the other location, by default. In support of this hypothesis, in Experiment 4, when a delay was inserted, prior to receiving the instructional cue, it had a disruptive effect on task accuracy proportional to the delay. Although the present results do not provide evidence for episodic memory, they do suggest that the pigeons have developed a single-code/default strategy that appears to be an efficient means of performing this task.

Background: Gluta mater gic N-methyl-D-aspartate (NMDA) receptors play vital roles in memory formation. Changes in the activity of these receptors influence memory processes. Ketamine is a noncompetitive NMDA receptor antagonist drug with promising mood-altering and pain-reducing effects in low doses. These effects are believed to be related to altered serotonergic transmission. Methods: The present study investigated the involvement of the serotonergic system in low-dose ketamine administrations' effects on memory acquisition, consolidation, and retrieval processes. Sixty-four male BALB/c mice were used in this experiment and separated into 8t groups. Mice were treated subchronically with a selective serotonin reuptake inhibitor, fluoxetine, and a serotonin depletion agent, p-chlorophenylalanine (pCPA). A serotonin antagonist, methiothepin, and ketamine were acutely administered 60 minutes before or after the behavioral tests. A passive avoidance (PA) test measured emotional memory acquisition, consolidation, and retrieval processes. Hippocampi malondialdehyde (MDA) levels were analyzed, and histopathological examinations were performed. Results: Ketamine alone did not significantly affect memory encoding processes in the PA test, while the ketamine-- fluoxetine combination disrupted memory consolidation. Fluoxetine negatively affected the memory acquisition process, which was normalized during the consolidation and retrieval trials. Drug applications did not significantly alter hippocampal MDA levels. In all ketamine-applied groups, histopathologic alterations were evident. Conclusion: Low-dose ketamine administration induces neurodegeneration, and it also impairs memory functions when combined with fluoxetine, indicating increased serotonergic transmission may be involved in the memory-impairing and neurotoxic effects of ketamine.

International relations (IR) scholars are increasingly interested in the role of memory in world politics. In this paper, we examine a key tension in the uptake of memory in IR between its status as a topic studied within IR and its use as an optic through which the basic categories of IR might be rethought. Focusing on the problem of scales of analysis, central within memory studies more broadly, we suggest that while memory poses a challenge to typical scalar arrangements in IR, such as "levels" of analysis, memory is often studied within these very arrangements. We argue that this is significant because questions of scale are at times the central political problem at stake in international memory. We track this tension between topic and optic in studies of memory, national identity, and foreign policy; studies of collective trauma and sovereignty; and studies of conflict and cooperation over memory.

This document is a response to a review of the book "The Great Exodus from China: Trauma, Memory, and Identity in Modern Taiwan." The author expresses gratitude for the review and discusses the interdisciplinary nature of research on social memory. The book focuses on the social traumas experienced by people displaced from China to Taiwan after the 1949 Chinese Communist Revolution and explores the ways in which they undertook social memory production efforts to mitigate these traumas. The author also highlights the lack of literature on the population exodus from China to Taiwan and its implications. The document addresses critiques of the book's analysis of trauma, memory, and reconciliation, particularly in relation to generation, temporality, and events. The author agrees with the critiques but offers some clarifications and reservations. The text discusses the concepts of theodicy, social memory, and cultural trauma in relation to the study of psychic trauma. The author explores the complexities of social trauma and social memory, highlighting the quest for meaning and explanation in the face of devastating events. They argue that memory can be both salutary and problematic, and that shared memories can reinforce victim identities. The author also introduces the concept of "multidirectional empathic unsettlements" as a modality for reconciliation between conflicting traumatic memories. They share their personal journey of grappling with conflicting emotions and developing empathy for the experiences of others. The author acknowledges the challenges of promoting reconciliation and emphasizes the importance of listening and understanding across mnemonic divides. [Extracted from the article]

Over the entire post-war period up to the present day, the endurance of fascism has remained a significant subject of Italian politics. The neo-fascist party, Movimento Sociale Italiano (M.S.I.), was born immediately after the Second World War. Furthermore, the transition to Republic coexisted with structural continuity with the dictatorship: many elements of fascist state, as the administrative institutions, central bureaucracy and economic ruling class, were maintained. Alongside concrete (both political and institutional) continuities, we can also observe diverse continuities that marked cultures, languages, and political discourses. The shadow of fascism has often invaded the public sphere in ways that condition the political debate and cultural imaginary. Firstly, for all the democratic and progressive parties and movements the Mussolini's dictatorship has been a constant negative reference point from which they openly distance themselves. Secondly, the spectre of fascism has always been evoked in the political debate with respect to the present and to warn against the return of authoritarianism in new forms. Thirdly, many periodicals, novels, films, comics, and television programmes trivialized the historical experience of Italian fascism, representing it, through recurrent narrative clichés, as a sort of phenomenon only partially corresponding to historical reality.

The memory of the Second World War is a widely debated topic in historiography, which has primarily investigated the channels that formed an indulgent and trivializing image of Italian participation in the conflict, according to the canon of the "good Italian" and the "bad German". This memory has developed primarily in Italy that did not identify with anti-fascism and tended to be more lenient even in remembering Mussolini's regime. This essay examines two magazines, Candido and Il Borghese, which are fully part of this anti-anti-fascist galaxy and the anti-communist right. The research was conducted on the periodicals from their first issues – from December 15, 1945, for Candido and from March 15, 1950, for Il Borghese – until 1956, focusing in particular on the interdependence between the memory of fascism and war and the political positions taken by the magazines.

This article examines the political movements that from the end of the Second World War until 2018 have explicitly inscribed themselves in the tradition of anti-fascism: the women who built nursery schools in Emilia Romagna; the young people with the 'striped T-shirts'; the students of 1968; the protesters who mobilized on 25 April 1994 to defend the values of the Resistance and the constitution after Silvio Berlusconi's rise to power; the 'Panther'. Finally, it will examine a wide arc of political actors – including immigrants – who united anti-racism and anti-fascism after Luca Traini's 2018 attempted massacre in Macerata. The article highlights how, over the decades, anti-fascism has proven to be a generative resource: it has not only been transmitted to new generations and new social actors, but has also been given new meaning over time to address new questions coming from the present. The fascism evoked has never been an eternal and a-historical phenomenon or a simulacrum of it. [ABSTRACT FROM AUTHOR]

The Christian Democratic interpretation of the fascist regime drew on the analyses conducted in the 1920s which identified the statism-racism-warmongering nexus as the defining trait of fascist movements. With the outbreak of the Cold War, the Italian fascism disappeared as a political phenomenon, but with Aldo Moro became a historical example of a system enemy of individual freedom but also responsible for policies that went against the interests of working people. In Moro's view, the birth of the Republic had opened up a new path that still had to be perfected but certainly in antithesis to the fascist one. The parties of the anti-fascist coalition had contributed to this new path and were called upon to complete it in a "progressive". This perspective carried on until the "national solidarity", but after Moro's assassination, the cultural and political framework in the 1980s, became increasingly critical of the cornerstones of post-1945 anti-fascism.

Since the 1980s, softened and positive portrayals of Fascism have become established in public debate in Italy. A key feature in this process of defascistization has been the reduction of Fascism to the cult of the Duce. This article examines how this narrative has emerged, focusing not on the politics of memory but instead on the role of the culture industry, public debate and the media. It examines three distinct but related phenomena: the 'Mussolinization' of Fascism in public narrative as promoted by television and other mass media; the transformation of the electoral system and political language, marked specifically by the shift from the centrality of the collective to that of authoritative and charismatic individuals; the prominent place of the figure of the hero in the popular culture.

It is not always easy to attend to task-relevant information and ignore task-irrelevant distractions. We investigated the impact of task switching and emotional stimuli on goal-oriented selective attention and subsequent recognition memory. Results from two experiments with different stimulus materials (words and images) found that the memory advantage of task-relevant information over task-irrelevant information (i.e. memory selectivity) was attenuated on task switch trials and emotional distractor trials. In contrast, task repetitions and emotional targets improved memory selectivity. These results suggest that both task switching and emotional distractors divert limited cognitive resources needed for selective attention and selective encoding. Emotional targets likely supported selective encoding through the process of attentional prioritisation of emotional stimuli. The effects of task switching and emotional stimuli did not interact, suggesting distinct mechanisms, although this conclusion remains tentative. [ABSTRACT FROM AUTHOR]

Previous research on whether source memory is enhanced for emotionally valenced sources yielded inconclusive results. To identify potential boundary conditions, we tested whether encoding instructions that promote affective versus different types of non-affective item-source-processing foster versus hamper source-valence effects. In both experiments, we used neutral words as items superimposed on emotional (positive & negative) or neutral pictures as sources. Source pictures were selected based on valence and arousal ratings collected in a pre-study such that only valence varied across sources. Source memory was measured via multinomial modelling. In Experiment 1, we applied an affective, item-focused orienting task (OT; i.e. word-pleasantness ratings) during item-source encoding and found enhanced source memory for emotionally valenced (positive & negative) compared to neutral sources. In Experiment 2, we systematically manipulated encoding instructions and again found enhanced source memory for emotionally valenced sources with an affective OT. No such effects occurred in the non-affective conditions, where participants were instructed to integrate item and source (item-source-fit judgments), to focus on the item (living-non-living judgments), or to encode the items only, respectively. With intentional item encoding, however, source memory was surprisingly better for positive than negative sources. We conclude that source-valence effects might unfold only under affective processing. [ABSTRACT FROM AUTHOR]

Simple Summary: Cancer significantly affects physical and mental health, evoking intense emotions and forcing life changes. Emotional responses to cancer treatment have an intrinsic connection with time, in particular with the positive memories of how life looked before the disease and the often grim and hopeless outlook on the future. This study found that patients in chemotherapy experience increased focus on the present, decreased focus on the future, and a sense of unpredictability, with a relatively short temporal horizon measured in weeks and months, not years. These experiences are prevalent regardless of the type of cancer, the length of treatment, and the sociodemographic background. It can be concluded that changed temporal experience during chemotherapy is a factor that can have an impact on patients' well-being and ability to cope with the disease. Understanding the impact of cancer on the experience of time is crucial in the context of hope and recovery. This study, a follow-up to a previous qualitative study of ovarian cancer patients – explored two types of such experiences—the memory of past happiness and the limited future planning. A sociodemographic questionnaire with nine questions about the experience of time was used on a convenience sample of 202 patients with various cancers, predominantly women with breast, ovarian, and cervical cancer. It was found that the respondents experienced increased focus on the present, decreased focus on the future, and a sense of unpredictability, with a relatively short temporal horizon measured in weeks and months, not years. Almost half of the respondents (46%) measured time during treatment by the rhythm of chemotherapy and check-ups, which thus appeared as the most meaningful events. The increase in the frequency with which patients underwent chemotherapy mildly affected their focus on the present (R = 0.25, p < 0.05), likely because of the discomfort of the side effects. The correlations between age and time in treatment, on the one hand, and the experience of time, on the other, were negligible. Changed temporal experience during chemotherapy is a factor that can have an impact on patients' well-being and ability to cope with the disease. It thus should be taken into account when planning oncology care. [ABSTRACT FROM AUTHOR]

A number of Mobile-Assisted-Language-Learning (MALL) apps have been developed to enlarge students' vocabulary. However, few studies have discussed the potential to learn words deeply and productively. Therefore, this study evaluated the effectiveness of a mind mapping MALL app as an aid to assist northern Taiwan EFL participants in learning vocabulary. The research questions aimed to examine changes in vocabulary learning outcomes, and the perspectives the participants held regarding the app. Data were collected through tests (pretest, posttest and delayed posttest), visualized vocabulary knowledge mind mappings, and surveys. The posttest results showed the use of the mind mapping MALL app enhanced EFL vocabulary learning (t = 3.68, p<.05; Cohen's d = 0.81, r = 0.38). In addition, based on the questionnaire responses, experimental participants agreed that not only did the MALL app provide them with a feasible way to move from receptive ways of learning to productive ways of learning, but it also bolstered word consciousness and word retention. Analytical ANCOVA results also verified that learners benefited more from the mind mapping app with respect to learning performance in their delayed posttest (t = 3.45, p<.05; Cohen's d = 0.77, r = 0.36). The findings may be construed as an effective method towards learning foreign words and further exploring the potential of vocabulary learning and MALL. [ABSTRACT FROM AUTHOR]

In this paper, a novel hyperspectral denoising method is proposed, aiming at restoring clean images from images disturbed by complex noise. Previous denoising methods have mostly focused on exploring the spatial and spectral correlations of hyperspectral data. The performances of these methods are often limited by the effective information of the neighboring bands of the image patches in the spectral dimension, as the neighboring bands often suffer from similar noise interference. On the contrary, this study designed a cross-band non-local attention module with the aim of finding the optimal similar band for the input band. To avoid being limited to neighboring bands, this study also set up a memory library that can remember the detailed information of each input band during denoising training, fully learning the spectral information of the data. In addition, we use dense connected module to extract multi-scale spatial information from images separately. The proposed network is validated on both synthetic and real data. Compared with other recent hyperspectral denoising methods, the proposed method not only demonstrates good performance but also achieves better generalization. [ABSTRACT FROM AUTHOR]

In the first three decades following the establishment of the People's Republic of China, the rapid urbanization in northeastern China and the promotion of atheism education and ethnic integration policies by the Chinese Communist Party pushed Shamanism, the religion of the Manchu ethnic group – a major minority in northeastern China – to the brink of extinction. However, during our investigation of Manchu autonomous villages in Jilin and Liaoning provinces in the Northeast, we discovered an emerging Manchu shamanic group calling themselves "Siden Saman" (Public shaman). They dedicate themselves to restoring Manchu identity and memory and are active in northeastern China. Although they are not the majority of the Shamanic population, they have established their influence in cyberspace. Through our tracking interviews over nearly six months, we believe that the religious practices of the Siden Saman should not be simply understood as an emerging religious force but rather as an effort by them to reconstruct their ethnic narrative. This effort is prominently manifested in their resistance to the history of 'de-Manchurization.' The resurgence of Siden Saman symbolizes the struggle for memory by minority ethnic groups against the backdrop of the long-term implementation of ethnic integration policies in China.

One of the most fundamental distinctions in cognitive psychology is between processing that is "controlled" and processing that is "automatic." The widely held automatic processing account of visualword identification asserts that, among other characteristics, the presentation of a well-formed letter string triggers sublexical, lexical, and semantic activation in the absence of any intention to do so. Instead, the role of intention is seen as independent of stimulus identification and as restricted to selection for action using the products of identification (e.g., braking in response to a sign saying "BRIDGE OUT"). We consider four paradigms with respect to the role of an intention--defined here as a "task set" indicating how to perform in the current situation--when identifying single well-formed letter strings. Contrary to the received automaticity view, the literature regarding each of these paradigms demonstrates that the relation between an intention and stimulus identification is constrained in multiple ways, many of which are not well understood at present. One thing is clear: There is no simple relation between an intention, in the form of a task set, and stimulus identification. Automatic processing of words, if this indeed ever occurs, certainly is not a system default. [ABSTRACT FROM AUTHOR]

This article looks at the photography of Kris Graves and the circulation of the artist's images on his social media accounts as a way of promoting social progress and racial justice, with a focus on his 2016 A Bleak Reality photoseries for Vanity Fair. The series consists of eight images that address the haunting specters of police brutality against eight African American male citizens who lost their lives at the hands of the state. Looking at Instagram, I posit a threefold claim about the social media photograph. First, I argue against the association of the social photo with the everyday. I examine a photoseries that initially participated in an economy of art but then migrated across a network of social relations in order to enhance its visibility—its dissemination ushering in the social life of the photograph that undergirds Black Lives Matter. Second, I suggest that the affective residues of Instagram's content linger in an indexical trace that transcends the transplatform network's digitally composited, modified, duplicated, and distributed images. This dual focus illuminates how social media function, on the one hand, as a technology of race while they allow Graves, on the other hand, to document instances of police brutality against African Americans. Third, in so doing, this article locates A Bleak Reality within a genealogy of civic media in order to explore how the co-optation of photography's reproductive affordances by African American photographers, artists, scholars, intellectuals, and abolitionists has allowed them to construct a counter-archive of Black cultural production around historical movements for racial justice.

The COVID‐19 pandemic constituted tremendous traumatic stress among the frontline healthcare workers. In the present study, we investigated relationships of two types of rumination, namely brooding and reflection, with traumatic stress and post‐traumatic growth and the mediating role of recollective experience in these relationships. A total of 88 healthcare workers (75% female, Mage = 54.91) actively providing service to COVID‐19 patients reported two memories of events that impacted them the most at the first peak of the pandemic and rated their recollective experience (i.e., phenomenological characteristics of memories). We used structural equation modelling to test whether recollective experience mediated the link of brooding and reflection with post‐trauma reactions of stress and growth. The findings showed that brooding and reflection were associated with higher levels of traumatic stress and post‐traumatic growth. Importantly, recollective experience mediated the relationship of rumination with traumatic stress but this differed for the type of rumination. Higher brooding was associated with greater traumatic stress and that relationship was independent of how well the memories were recollected, while for reflection, high reflection was associated with stronger recollective experience, which predicted higher traumatic stress and post‐traumatic growth. The present study shows the functional dimensions of reflective rumination and presents novel findings that demonstrates the discrete mnemonic mechanisms underlying the association between brooding, reflection, and post‐trauma reactions.

Preterm birth (< 37 weeks gestation) has been associated with memory deficits, which has prompted investigation of possible alterations in hippocampal volume in this population. However, existing literature reports varying effects of premature birth on hippocampal volume. Specifically, it is unclear whether smaller hippocampal volume in preterm-born individuals is merely reflective of smaller total brain volume. Further, it is not clear if hippocampal volume is associated with episodic memory functioning in preterm-born individuals. Meta-analysis was used to investigate the effects of premature birth on hippocampal volume and episodic memory from early development to young adulthood (birth to 26). PubMed, PsychINFO, and Web of Science were searched for English peer-reviewed articles that included hippocampal volume of preterm and term-born individuals. Thirty articles met the inclusion criteria. Separate meta-analyses were used to evaluate standardized mean differences between preterm and term-born individuals in uncorrected and corrected hippocampal volume, as well as verbal and visual episodic memory. Both uncorrected and corrected hippocampal volume were smaller in preterm-born compared to term-born individuals. Although preterm-born individuals had lower episodic memory performance than term-born individuals, the limited number of studies only permitted a qualitative review of the association between episodic memory performance and hippocampal volume. Tested moderators included mean age, pre/post-surfactant era, birth weight, gestational age, demarcation method, magnet strength, and slice thickness. With this meta-analysis, we provide novel evidence of the effects of premature birth on hippocampal volume. [ABSTRACT FROM AUTHOR]

Purpose: Verbal working memory is poorer for children with hearing loss than for peers with normal hearing (NH), even with cochlear implantation and early intervention. Poor verbal working memory can affect academic performance, especially in higher grades, making this deficit a significant problem. This study examined the stability of verbal working memory across middle childhood, tested working memory in adolescents with NH or cochlear implants (CIs), explored whether signal enhancement can improve verbal working memory, and tested two hypotheses proposed to explain the poor verbal working memory of children with hearing loss: (a) Diminished auditory experience directly affects executive functions, including working memory; (b) degraded auditory inputs inhibit children’s abilities to recover the phonological structure needed for encoding verbal material into storage. Design: Fourteen-year-olds served as subjects: 55 with NH; 52 with CIs. Immediate serial recall tasks were used to assess working memory. Stimuli consisted of nonverbal, spatial stimuli and four kinds of verbal, acoustic stimuli: nonrhyming and rhyming words, and nonrhyming words with two kinds of signal enhancement: audiovisual and indexical. Analyses examined (a) stability of verbal working memory across middle childhood, (b) differences in verbal and nonverbal working memory, (c) effects of signal enhancement on recall, (d) phonological processing abilities, and (e) source of the diminished verbal working memory in adolescents with cochlear implants. Results: Verbal working memory remained stable across middle childhood. Adolescents across groups performed similarly for nonverbal stimuli, but those with CIs displayed poorer recall accuracy for verbal stimuli; signal enhancement did not improve recall. Poor phonological sensitivity largely accounted for the group effect. Conclusions: The central executive for working memory is not affected by hearing loss or cochlear implantation. Instead, the phonological deficit faced by adolescents with CIs denigrates the representation in storage and augmenting the signal does not help. [ABSTRACT FROM AUTHOR]

Purpose: Traumatic brain injury (TBI) is associated with a range of cognitive-communicative deficits that interfere with everyday communication and social interaction. Considerable effort has been directed at characterizing the nature and scope of cognitive-communication disorders in TBI, yet the underlying mechanisms of impairment are largely unspecified. The present research examines sensitivity to a common communicative cue, disfluency, and its impact on memory for spoken language in TBI. Method: Fifty-three participants with moderate–severe TBI and 53 non-injured comparison participants listened to a series of sentences, some of which contained disfluencies. A subsequent memory test probed memory for critical words in the sentences. Results: Participants with TBI successfully remembered the spoken words (b = 1.57, p < .0001) at a similar level to non-injured comparison participants. Critically, participants with TBI also exhibited better recognition memory for words preceded by disfluency compared to words from fluent sentences (b = 0.57, p = .02). Conclusions: These findings advance mechanistic accounts of cognitive-communication disorder by revealing that, when isolated for experimental study, individuals with moderate–severe TBI are sensitive to attentional orienting cues in speech and exhibit enhanced recognition of individual words preceded by disfluency. These results suggest that some aspects of cognitive-communication disorders may not emerge from an inability to perceive and use individual communication cues, but rather from disruptions in managing (i.e., attending, weighting, integrating) multiple cognitive, communicative, and social cues in complex and dynamic interactions. This hypothesis warrants further investigation. [ABSTRACT FROM AUTHOR]

Purpose: Nonword repetition (NWR) has been described as a clinical marker of developmental language disorder (DLD), as NWR tasks consistently discriminate between DLD and typical development (TD) cross-linguistically, with Cantonese as the only reported exception. This study reexamines whether NWR is able to generate TD/DLD group differences in Cantonese-speaking children by reporting on a novel set of NWR stimuli that take into account factors known to affect NWR performance and group differentiation, including lexicality, sublexicality, length, and syllable complexity. Method: Sixteen Cantonese-speaking children with DLD and 16 age-matched children with TD repeated two sets of high-lexicality nonwords, where all constituent syllables are morphemic in Cantonese but meaningless when combined, and one set of low-lexicality nonwords, where all constituent syllables are nonmorphemic. Low-lexicality nonwords were further classified on sublexicality in terms of consonant–vowel (CV) combination attestedness (whether or not CV combinations in nonword syllables occur in real Cantonese words). Results: Children with DLD scored significantly below their peers with TD. Effect sizes showed that high-lexicality nonwords and nonword syllables with attested CV combinations offered the greatest TD/DLD group differentiation. Nonword length and syllable complexity did not affect TD/DLD group differentiation. Conclusions: NWR can capture TD/DLD group differences in Cantonese speaking children. Lexicality and sublexicality effects must be considered in designing NWR stimuli for TD/DLD group differentiation. Future studies should replicate the present study on a larger sample size and a younger population as well as examine the diagnostic accuracy of this NWR test. [ABSTRACT FROM AUTHOR]

Introduction: Teleneuropsychology, which includes the remote application of neuropsychological tests to patients via telephone or videoconferencing, can expand access to health services for patients who reside in distant areas or have mobility restrictions. With the emergence of the COVID-19 pandemic, there has been a significant increase in the use of teleneuropsychology in cognitive assessment. In this review, the aim was to critically review the results of studies conducted in the field of teleneuropsychology and the fundamental principles related to teleneuropsychological assessment. Additionally, the "guideline for homebased teleneuropsychology" developed for Türkiye's practices is outlined in this review. Method: A literature search was conducted using the Web of Science and PubMed databases to include all types of articles related to the subject. Results: The results of studies on in-clinic and home-based teleneuropsychological assessment indicate that tests that assess cognitive functions such as attention, memory, executive functions, and language, particularly those based on verbal administration, can be reliably applied through teleneuropsychological assessment. However, there are factors to consider when referring patients for teleneuropsychological assessment, selecting tests for assessment, and making ethical considerations. Additionally, it is important to follow recommended steps for both the clinician and the patient and/or their caregiver before and during the interview in order for the assessment to be carried out effectively. Conclusion: Although direct contact with the patient is an essential element in clinical neuropsychology practice, when necessary, teleneuropsychological assessment performed by trained experts following appropriate application procedures can be a good alternative to face-to-face evaluations.
