Abstract

Abstract When observers have to identify an object embedded in a rapid serial visual presentation (RSVP) stream, they often erroneously report the identity of a distractor instead of the target (distractor intrusion). In two experiments, we examined whether these intrusion errors are associated with the speed of attentional engagement. Participants reported the identity of target digits indicated by shape selection cues. To manipulate the speed of engagement, targets appeared either within a single RSVP stream or unpredictably in one of two streams. Objects that followed the selection cue were reported more frequently when engagement was delayed (two streams), whereas the probability of reporting objects preceding the cue was higher when engagement was faster (single stream). These results show that distractor intrusions are closely linked to the allocation of selective attention in time, making the intrusion paradigm a useful tool for research into the temporal dynamics of attention. They also provide new evidence for the idea that attentional selectivity operates within brief periods of perceptual enhancement (attentional episodes), facilitating the processing of all objects within this period, regardless of their status as targets or distractors.

Abstract

The article discusses the need for psychological researchers to consider wider ethical guidelines for socially responsible science. It highlights the potential harm that studies can have on society, even if they are methodologically sound. The article presents examples of retracted papers that promoted stigmatizing or harmful ideas and argues that current guidelines for retraction do not address negative impacts. It also discusses a controversial ethical guideline proposed by the journal Nature Human Behavior, which suggests that some studies should not be published or retracted even if they are methodologically sound. The article concludes by offering recommendations for researchers to improve their decision-making and be more socially responsible in their work. [Extracted from the article]

Abstract

Many models of attention assume that categorization (the individuation of events based on the feature dimension relevant for response selection) occurs only after an object has been selected and encoded in working memory (WM). In contrast, we propose that the match between an item and the currently activated set of possible response features (categorization template) already modulates selective perceptual processing prior to WM encoding. To test this proposal, we measured electrophysiological markers of attentional engagement (N2pc components) and behavioral interference effects from posttarget distractors (PTDs) as a function of whether these distractors matched the categorization template. Participants were presented with rapid serial visual presentations (RSVPs) of digits and letters and had to identify a target indicated by a surrounding shape in these RSVP streams. Targets were drawn from a subset of items within an alphanumeric category. Accuracy was highest when the PTD belonged to the irrelevant alphanumeric category, lower when the PTD matched the target's alphanumeric category but not the categorization template, and lowest when the PTD matched the categorization template. On trials with template-matching PTDs, target-elicited N2pc components were temporally extended, indicative of additional attentional amplification triggered by these PTDs. We propose that this amplification produces increased competition between targets and PTDs, resulting in performance costs. These results provide new evidence for the continuous nature of evidence accumulation and attentional modulations during perceptual processing. They show that attentional selectivity is not exclusively mediated by search templates, but that categorization templates also play an important and often overlooked role.

Abstract

During the past two decades, the unequivocally recommended treatment method of Type 2 diabetes mellitus was insulin administration and intensification in the earliest possible stage of the diagnosis. This approach is not only unfounded but was never scientifically proven. Yet, it has been zealously advocated to medical professionals. In fact, a sound body of evidence disproves this long-standing treatment approach. This method is a cornerstone of, what we now know to be two great illusions of past century, namely, glucocentrism and intensification. Numerous recently published studies provide alarming data regarding serious side effects of blind intensification and insulin overdosing in T2DM. They raise major concerns and call for revision of the traditional approach. Since insulin is an integral and deeply rooted part of the intensification agenda of treating T2DM, it has now suffered a serious drawback. Alternatively, in this review authors present the novel Gravicentric (Energy) concept of T2DM acceptance and therapy. They offer a new classification of anti-diabetes drugs based on their energy effect and present their Gravicentric Algorithm for wide practical utilization. For that reason, the "ELEPHANT" abbreviation was found as a helpful reminder. Viewing T2DM as disease of energy balance together with anti – energy drugs implementation provide medical doctors an unique opportunity to transform T2DM from "slowly – progressive" disease to rapidly reversible condition, which it actually is.

24. Bisexual stereotypes in clinical evaluation

Abstract

Psychologists nowadays tend to view same-sex attraction as a normal part of human sexuality, but it is less clear whether they still hold prejudicial views regarding bisexuality. Previous studies have demonstrated that psychotherapists’ clinical evaluation is affected by whether their client is bisexual. One plausible interpretation is that such differences stem from an uncritical adoption of bisexual stereotypes, namely, that bisexual people are confused, immature, and unable to maintain romantic relationships. However, an alternative hypothesis suggests that differences in evaluation may be based on the psychotherapists’ experience with bisexual clients. To adjudicate between these possibilities, psychotherapists and clinical psychology interns (N=229) were presented with a description of a hypothetical client—a bisexual man, a gay man, or a heterosexual man—seeking counseling for academic issues. Compared to non-bisexual clients, bisexual clients were evaluated as more likely to suffer from identity and relationship issues. These clinical evaluations were observed regardless of whether the therapist was personally acquainted with bisexual people or had any experience with bisexual clients. Instead, stereotypical clinical issues were perceived as particularly salient among psychotherapists who viewed the hypothetical bisexual clients as immature and confused. These results suggest that like the general public, psychotherapists adhere to stereotypical beliefs about bisexual people. Such biases are likely to have negative impacts on bisexual clients’ diagnoses and overall satisfaction from therapy. We conclude that education may be key to curbing anti-bisexual bias among psychotherapists and ensuring better therapeutic outcomes for bisexual clients.

25. Perceptual Processing is Not Spared During the Attentional Blink

Abstract

Identification of the second of two targets is impaired when these appear within 500 ms of each other. This phenomenon, known as the attentional blink (AB) is thought to reflect disrupted post-perceptual processing. Yet, decisive empirical support for this claim is lacking. We measured the depth of the AB, while manipulating the second target’s reporting feature. We reasoned that if perceptual processing is unaffected by the blink, all the features of the blinked target should have equal access to working memory. In contrast with this prediction, we found identity and semantic-category reports to be more severely impaired by the blink than color reports, although baseline performance was similar in the two report conditions. These findings suggest that high-level features are more poorly represented in working memory than low-level features during the blink. We conclude that the attentional blink disrupts perceptual processing. Implications for contemporary models of the attentional blink are discussed.

26. The number of expected targets modulates access to working memory: A new unified account of lag-1 sparing and distractor intrusions

Abstract

In rapid serial visual presentation (RSVP) tasks, failures of attentional selectivity are frequently observed when a single target is followed by a potentially reportable distractor (distractor intrusions). However, in tasks with two targets, accuracy for both targets is typically high when they are presented in immediate succession (lag-1 sparing). To account for this apparent contradiction, we tested whether expectations about the number of targets affects the number of items encoded in working memory (WM). Colored target digits were embedded among gray letters and digits. The first target was followed either by a gray digit, or a second target (another colored digit). To manipulate expectations, the ratio of one-target and two-targets trials (75% to 25% or vice versa) was varied between blocks. Participants were much more likely to report seeing two targets when two targets were expected. Analogous results were obtained in an additional experiment where two successive colored digits appeared on all trials, and participants were instructed to either report both or only the first digit. ERP markers of attentional allocation (N2pc) and WM storage processes (contralateral delayed activity, CDA) were larger when two targets were expected, regardless of the actual number of targets. These results show that the number of expected targets modulates the activation of sensory representations during attentional episodes, which affects the probability that they are subsequently encoded in WM. These findings suggest that a single mechanism can account both for lag-1 sparing and distractor intrusions in RSVP tasks. They also provide new evidence for strategic top-down control over WM encoding. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

29. Beliefs about the inevitability of sexual attraction predict stereotypes about asexuality

Abstract

Similar to other sexual minorities, asexual individuals often face prejudice and stereotyping. However, the source of these attitudes and beliefs is not well understood. We hypothesized that asexual stereotypes stem from the belief that sexual attraction is an inevitable part of human development. This attraction inevitability assumption can lead to the deduction that people who identify as asexual do so because they are going through a transitory stage or excusing socially avoidant tendencies. To test this stereotype deduction account, we examined whether specific asexual stereotypes (immaturity and non-sociality) are associated with adherence to the attraction inevitability assumption. Heterosexual participants (N = 322; 201 women, 114 men; average age 34.6 yrs.) from the UK and the US read vignettes describing a target character that was either asexual or heterosexual. People who assumed that attraction is inevitable were more likely to evaluate asexual targets (but not heterosexual targets) as immature and non-social. The impact of the sexual inevitability assumption was present even when social dominance orientation, an attitude closely related to negativity towards all sexual minorities, was accounted for. Participants who adhered to the attraction inevitability assumption also showed a reduced inclination to befriend asexual individuals. These findings suggest that generalized negativity towards sexual minorities does not fully explain stereotypes and prejudice against asexual people. Instead, the current study highlights how perceived deviation from the shared understanding of sexuality uniquely contributes to anti-asexual bias.

Abstract

Alerting, the process of achieving and maintaining a state of optimal vigilance, is crucial for detecting relevant stimuli and task performance. Age-related decline in the ability to use alerting cues is widely reported and attributed to changes in noradrenergic signaling. However, it remains to be determined whether aging affects all forms of alerting cues equally and whether older adults differently modulate their alerting sensitivity based on differences in cue predictivity relevant to the target task. We examined the performance of 135 younger adults and 103 older adults on three versions of the Attention Networks Test, using locational but spatially nonpredictive visual cues, locational spatially predictive visual cues, and spatially predictive auditory cues. Analysis of alerting effects indicated that while older adults derived less benefit from visual alerting cues than younger adults, they used auditory alerting cues equally well. Furthermore, cue spatial predictivity did not impact on aging effects on alerting. This heterogeneity in aging effects on alerting may indicate that they result primarily from cognitive rather than neuromodulatory changes.

Abstract

© 2019 Elsevier Ltd. All rights reserved., Background: Non-alcoholic steatohepatitis (NASH) is a common type of chronic liver disease that can lead to cirrhosis. Obeticholic acid, a farnesoid X receptor agonist, has been shown to improve the histological features of NASH. Here we report results from a planned interim analysis of an ongoing, phase 3 study of obeticholic acid for NASH. Methods: In this multicentre, randomised, double-blind, placebo-controlled study, adult patients with definite NASH, non-alcoholic fatty liver disease (NAFLD) activity score of at least 4, and fibrosis stages F2-F3, or F1 with at least one accompanying comorbidity, were randomly assigned using an interactive web response system in a 1:1:1 ratio to receive oral placebo, obeticholic acid 10 mg, or obeticholic acid 25 mg daily. Patients were excluded if cirrhosis, other chronic liver disease, elevated alcohol consumption, or confounding conditions were present. The primary endpoints for the month-18 interim analysis were fibrosis improvement (≥1 stage) with no worsening of NASH, or NASH resolution with no worsening of fibrosis, with the study considered successful if either primary endpoint was met. Primary analyses were done by intention to treat, in patients with fibrosis stage F2-F3 who received at least one dose of treatment and reached, or would have reached, the month 18 visit by the prespecified interim analysis cutoff date. The study also evaluated other histological and biochemical markers of NASH and fibrosis, and safety. This study is ongoing, and registered with ClinicalTrials.gov, NCT02548351, and EudraCT, 20150-025601-6. Findings: Between Dec 9, 2015, and Oct 26, 2018, 1968 patients with stage F1-F3 fibrosis were enrolled and received at least one dose of study treatment; 931 patients with stage F2-F3 fibrosis were included in the primary analysis (311 in the placebo group, 312 in the obeticholic acid 10 mg group, and 308 in the obeticholic acid 25 mg group). The fibrosis improvement endpoint was achieved by 37 (12%) patients in the placebo group, 55 (18%) in the obeticholic acid 10 mg group (p=0·045), and 71 (23%) in the obeticholic acid 25 mg group (p=0·0002). The NASH resolution endpoint was not met (25 [8%] patients in the placebo group, 35 [11%] in the obeticholic acid 10 mg group [p=0·18], and 36 [12%] in the obeticholic acid 25 mg group [p=0·13]). In the safety population (1968 patients with fibrosis stages F1-F3), the most common adverse event was pruritus (123 [19%] in the placebo group, 183 [28%] in the obeticholic acid 10 mg group, and 336 [51%] in the obeticholic acid 25 mg group); incidence was generally mild to moderate in severity. The overall safety profile was similar to that in previous studies, and incidence of serious adverse events was similar across treatment groups (75 [11%] patients in the placebo group, 72 [11%] in the obeticholic acid 10 mg group, and 93 [14%] in the obeticholic acid 25 mg group). Interpretation: Obeticholic acid 25 mg significantly improved fibrosis and key components of NASH disease activity among patients with NASH. The results from this planned interim analysis show clinically significant histological improvement that is reasonably likely to predict clinical benefit. This study is ongoing to assess clinical outcomes.
