Aim: This study aimed to assemble and critically reflect on previously acquired insights from investigations that have already been conducted into the role of self-compassion in diabetes and its management. Methods: This study implemented a rapid review approach to assess the pre-existing knowledge in a time-sensitive manner. A rapid review involves the synthesis of existing knowledge using a simplified systematic review process. Results: A total of 16 articles were identified for this rapid review. The main findings from these articles included that self-compassion is associated with improved outcomes (psychologically and medically), self-compassion can be improved through interventions, and that many extraneous factors influence levels of self-compassion. Conclusion: It is apparent that self-compassion plays a rather significant role in the management of diabetes, and that interventions aimed at developing self-compassion showed success in improving health-related outcomes. It is suggested that future research should build on the possibility of using positive psychology interventions to improve the quality of life of those living with diabetes, and work to better understand the influence of aspects such as gender and diabetes duration on self-compassion.

As the science of wellbeing has grown, universities have adopted the challenge of prioritizing the wellbeing of students. Positive psychology interventions (PPIs), activities designed to increase the frequency of positive emotions and experiences, which help to facilitate the use of actions and thoughts that lead to human flourishing, are being increasingly used worldwide. Known to boost wellbeing and a number of other variables, it nonetheless remains unknown whether their use can influence other variables in non-Western cultures. In this study, we determined the impact of PPIs on a variety of wellbeing outcomes. The 6-week PPI program was conducted in the United Arab Emirates on Emirati university students (n = 120) who reported more positive emotion and overall balance of feelings that favored positivity over time relative to a control group. Yet, there was no effect found on negative emotions, life satisfaction, perceived stress, fear of happiness, locus of control, or somatic symptoms, and no effect on levels of collectivism or individualism. Our findings nonetheless support the use of PPIs in higher education as they show an increase in the experience of positive emotion, with this in itself bringing positive life outcomes, and no negative impact on culture. Our findings serve to build a foundation for understanding for whom PPIs work best - and least - around the world. [ABSTRACT FROM AUTHOR]

The Pavlovian-to-instrumental transfer (PIT) paradigm measures the effects of Pavlovian conditioned cues on instrumental behavior in the laboratory. A previous study conducted by our research group observed activity in the left nucleus accumbens (NAcc) elicited by a non–drug-related PIT task across patients with alcohol dependence (AD) and healthy control subjects, and the left NAcc PIT effect differentiated patients who subsequently relapsed from those who remained abstinent. In this study, we aimed to examine whether such effects were present in a larger sample collected at a later date. A total of 129 recently detoxified patients with AD (21 females) and 74 healthy, age- and gender-matched control subjects (12 females) performing a PIT task during functional magnetic resonance imaging were examined. After task assessments, patients were followed for 6 months. Forty-seven patients relapsed and 37 remained abstinent. We found a significant behavioral non–drug-related PIT effect and PIT-related activity in the NAcc across all participants. Moreover, subsequent relapsers showed stronger behavioral and left NAcc PIT effects than abstainers. These findings are consistent with our previous findings. Behavioral non–drug-related PIT and neural PIT correlates are associated with prospective relapse risk in AD. This study replicated previous findings and provides evidence for the clinical relevance of PIT mechanisms to treatment outcome in AD. The observed difference between prospective relapsers and abstainers in the NAcc PIT effect in our study is small overall. Future studies are needed to further elucidate the mechanisms and the possible modulators of neural PIT in relapse in AD. [ABSTRACT FROM AUTHOR]

Health psychology as a discipline has existed for more than four decades and is primarily concerned with research, theory, and practice at the nexus of psychology and health. The discipline is well established across Europe, the United States, and Australia with health psychology societies, postgraduate programmes, conferences, and academic journals dedicated to the discipline in the majority of these countries. However, in South Africa, health psychology remains a broad umbrella term under which psychologists and other health care professionals conduct research. Health psychology is concerned with the biological, social, psychological, contextual, and structural drivers of health and illness, and relies on theory and empirically-driven research to identify and understand important links between health and behaviour. In South Africa, where a large proportion of the population faces multiple co-occurring disease epidemics, such as HIV/AIDS, TB, COVID-19, diabetes, and heart disease, there is a need for a uniting sub-discipline like health psychology to focus intervention efforts and to meet the sustainable development goals. The recent re-establishment of a special interest group in health psychology in the Psychological Society of South Africa (PsySSA) is an important first step. In this article, and as members of the newly re-established special interest group in health psychology, we call attention to the need to promote health psychology in South Africa. In this article, we describe the paradigmatic traditions and theoretical models that inform the discipline. We then argue why health psychology should be prioritised again and recommend future directions for health psychology in South Africa. [ABSTRACT FROM AUTHOR]

Rationale: Adenosine A2A receptors (A2AR) in the dorsal striatum have been implicated in goal-directed behaviour. While activation of these receptors with several methods has resulted in an insensitivity to outcome devaluation, particular explanations for how they disrupt behaviour have not been explored. We both confirm a role for A2A receptors in goal-directed responding and evaluate additional behavioural aspects of goal-directed control to more fully understand the role of A2A receptors in instrumental behaviour. Objectives: To examine the effects of the adenosine A2A agonist CGS-21680 in the DMS on response-outcome encoding, updating representations of outcome value and on the ability to inhibit behaviour when reward is not available. Methods: Male rats were trained to lever press for food reward. The A2AR agonist CGS-21680 was infused into the dorsomedial striatum either before an outcome devaluation test, prior to training with two distinct response-outcome associations or prior to a test of discriminative stimulus control over instrumental performance. Results: Intra-DMS administration of CGS-21680 impaired sensitivity to outcome devaluation. CGS-21680 treatment did not impair acquisition of specific response-outcome associations, selective control of responding based on the presence of stimuli that signaled when reward was or was not available, discrimination between stimuli or lever choices nor did it influence the effect of devaluation on the amounts of food eaten in a consumption test. Conclusions: CGS-21680 impairs the ability to modulate responding based on recent changes to outcome value, an effect that is not accounted for by impairments in behavioural inhibition, discrimination, encoding the specific outcome of a response or the effectiveness of specific satiety.

We studied competitive interactions of rats during instrumental foraging behavior. Two groups of animals were revealed: rats with predominance of operant actions for getting food reinforcements (donors) and kleptoparasites that more often get food after instrumental acts of the partners. Intergroup differences began to appear and increased from 3-4 paired experiments. It was revealed that at the individual stage of learning the instrumental skill, donor rats were faster in learning and showed high foraging activity with shorter latency in comparison with kleptoparasites, which were initially slower and performed a large number of inter-signal actions in the form of unconditioned peeking into the feeder.

Objective: Positive psychology is a revolution in the science of psychology as well as a new milestone in the development of human society. The purpose of the study was to use bibliometrics and visual analysis to assess the current state and trends in positive psychology research. Methods: The Web of Science Core Collection was searched for 4,378 papers on positive psychology between 1999 and 2021. The features of positive psychology research were analyzed using Microsoft Excel 2013, VOSviewer (1.6.17), and CiteSpace (5.8.R1). Results: The findings demonstrate a steady growth in positive psychology publications from 1999 to 2021. The United States (1,780) and Harvard University (104), respectively, were the most productive nations and organizations in this subject. Frontiers in Psychology was the most productive journal (288), while the Journal of Personality and Social Psychology had the most co-citations (8,469). Seligman was the most influential author, with 3,350 citations and 5,020 co-citations. The top ten co-cited references, in terms of citation explosion, suggesting that these papers provide the foundation for the growth of this discipline. The systematic review, character strengths, positive psychology intervention, language pleasure, and the COVID-19 pandemic are the focal points of research and development developments in this discipline. Conclusion: These findings have helped researchers in positive psychology find new ways to collaborate with partners, hot topics, and research frontiers. [ABSTRACT FROM AUTHOR]

During the past years scholars have shown an increasing interest in supporting students' self-regulated learning (SRL). Learning analytics (LA) can be applied in various ways to identify a learner's current state of self-regulation and support SRL processes. It is important to examine how LA has been used to identify the need for support in different phases of SRL cycle, which channels are used to mediate the intervention and how efficient and impactful the intervention is. This will help the learners to achieve the anticipated learning outcomes. The systematic literature review followed PRISMA 2020 statement to examine studies that applied LA interventions to enhance SRL. The search terms used for this research identified 753 papers in May 2021. Of these, 56 studies included the elements of LA, SRL, and intervention. The reviewed studies contained various LA interventions aimed at supporting SRL, but only 46% of them revealed a positive impact of an intervention on learning. Furthermore, only four studies reported positive effects for SRL and covered all three SRL phases (planning, performance, and reflection). Based on the findings of this literature review, the key recommendation is for all phases of SRL to be considered when planning interventions to support learning. In addition, more comparative research on this topic is needed to identify the most effective interventions and to provide further evidence on the effectiveness of interventions supporting SRL.

The current study investigated the effectiveness of a group on-line positive psychology intervention (OPPI) designed to mitigate the psychological impact of the COVID-19 pandemic and the subsequent measures to control it. Study participants (N = 82, Mage = 33.07, SD = 9.55) were all Greek adults divided into an intervention (n = 44) and a control group (n = 38). The intervention group attended a voluntary, online, two-week, six-session (each 50 min), group intervention. The intervention aimed at enhancing participants' personal strengths and resilience in order to cope more effectively with the psychological impact of social distancing (e.g., feelings of anxiety, sadness, fear, and/or loneliness). All participants completed an online questionnaire one week before the intervention's implementation, which included scales measuring their: demographic characteristics, empathy, resilience, affectivity, feelings of loneliness, depression and anxiety levels, and feelings of fear regarding the outbreak. Participants in both the intervention and control group completed the same measures the week following the intervention's termination to examine its effects, and two weeks later to examine its long-term effectiveness. The intervention was found to be effective in alleviating the impact of the pandemic and in strengthening participants' resilience. More specifically, the results showed significant decreases for the intervention group in all measures of psychosocial distress (anxiety, depression, loneliness and fear) and significant increases in empathy, resilience, and experience of positive emotions. The study's implications for the development and implementation of online psychological interventions during a crisis are discussed. [ABSTRACT FROM AUTHOR]

Background: The reinforcing properties of nicotine play a critical role in smoking and vaping. There is a need for treatments that decrease the reinforcing properties of nicotine and thereby improve smoking and vaping rates. Dopamine plays a role in the reinforcing properties of nicotine, but little is known about the role of dopamine D2-like receptors in nicotine intake and whether there are sex differences in the effects of dopaminergic drugs on nicotine intake. Aim: The goal of the present studies was to investigate the effects of the D1/D2-like receptor antagonist flupentixol and the D2-like receptor antagonist L-741626 on nicotine self-administration in male and female rats. Methods: The effects of flupentixol and L-741626 on operant responding for nicotine and food and locomotor activity in a small open field were investigated. Results: There were no sex differences in baseline nicotine intake. The D1/D2-like receptor antagonist flupentixol and the D2-like receptor antagonist L-741626 decreased operant responding for nicotine. Blockade of D1/D2-like receptors and blockade of D2-like receptors also decreased operant responding for food and decreased locomotor activity. Flupentixol induced a greater decrease in operant responding for food in males than females. However, in the other tests, there were no sex differences in the effects of the dopamine receptor antagonists. Conclusions: Blockade of D1/D2-like receptors with flupentixol and D2-like receptors with L-741626 decreases nicotine and food intake in rats of both sexes. These compounds also decrease locomotor activity which might be indicative of a sedative effect. [ABSTRACT FROM AUTHOR]

From the COVID-19 global pandemic to racial injustice and the continued impact of climate change on communities across the globe, the past couple of years have demonstrated the need for a greater understanding of how to protect people from the negative consequences of stress. Here, I outline a perspective on how the brain's reward system might be an important, but often understudied, protective mechanism for stress resilience and stress-related health outcomes. I describe work suggesting that engagement of the reward system inhibits the stress response and is associated with improved health outcomes, including reduced depressive symptomatology and slowed cancer progression. I then highlight important future directions for translational research and illustrate the value of this perspective for improving behavioral interventions in clinical psychology and beyond.

Background: Community pharmacies are well-placed to deliver well-being interventions; however, to date, nothing has been produced specifically for this setting. The aim of this study was to develop a positive psychology intervention suitable for a community pharmacy setting with the goal of increasing the well-being of community members. Methods: Intervention development consisted of three steps: Step 1—identify the evidence-base and well-being model to underpin the basis of the intervention (Version 1); Step 2—model the intervention and gather user feedback to produce Version 2, and Step 3—revisit the evidence-base and refine the intervention to produce Version 3. Results: Findings from nine studies (seven RCTs, one cross-sectional, one N-1 design plus user feedback were applied to model a 6-week 'Prescribing Happiness (P-Hap)' intervention, underpinned by the PERMA model plus four other components from the positive psychology literature (Three Good Things, Utilising Your Signature Strengths in New Ways, Best Possible Selves and Character Strengths). A PERMA-based diary was designed to be completed 3 days a week as part of the intervention. Conclusions: This work is an important development which will direct the future implementation of interventions to support well-being in this novel setting. The next stage is to gain the perspectives of external stakeholders on the feasibility of delivering the P-Hap for its adoption into community pharmacy services in the future. [ABSTRACT FROM AUTHOR]

There is a growing interest in human-computer interaction (HCI) to envision, design, and evaluate technology-enabled interventions that support users’ emotion regulation. This interest stems in part from increased recognition that the ability to regulate emotions is critical to mental health, and that a lack of effective emotion regulation is a transdiagnostic factor for mental illness. However, the potential to combine innovative HCI designs with the theoretical grounding and state-of-the-art interventions from psychology has yet to be fully realised. In this article, we synthesise HCI work on emotion regulation interventions and propose a three-part framework to guide technology designers in making: (i) theory-informed decisions about intervention targets; (ii) strategic decisions regarding the technology-enabled intervention mechanisms to be included in the system; and (iii) practical decisions around previous implementations of the selected intervention components. We show how this framework can both systematise HCI work to date and suggest a research agenda for future work. [ABSTRACT FROM AUTHOR]

Model-free and model-based computations are argued to distinctly update action values that guide decision-making processes. It is not known, however, if these model-free and model-based reinforcement learning mechanisms recruited in operationally based instrumental tasks parallel those engaged by pavlovian-based behavioral procedures. Recently, computational work has suggested that individual differences in the attribution of incentive salience to reward predictive cues, that is, sign- and goaltracking behaviors, are also governed by variations in model-free and model-based value representations that guide behavior. Moreover, it is not appreciated if these systems that are characterized computationally using model-free and model-based algorithms are conserved across tasks for individual animals. In the current study, we used a within-subject design to assess sign-tracking and goal-tracking behaviors using a pavlovian conditioned approach task and then characterized behavior using an instrumental multistage decision-making (MSDM) task in male rats. We hypothesized that both pavlovian and instrumental learning processes may be driven by common reinforcement-learning mechanisms. Our data confirm that sign-tracking behavior was associated with greater reward-mediated, model-free reinforcement learning and that it was also linked to model-free reinforcement learning in the MSDM task. Computational analyses revealed that pavlovian model-free updating was correlated with model-free reinforcement learning in the MSDM task. These data provide key insights into the computational mechanisms mediating associative learning that could have important implications for normal and abnormal states. [ABSTRACT FROM AUTHOR]

A global challenge is the shift to a digital and ecological economy. By exchanging knowledge and best practices, the framework created for this study aims to ease this transition, particularly for developing and underdeveloped nations. This study aims to answer the question, "What are the levers to implement the circular economy in smart cities?". An integrative literature search was conducted. Approximately forty articles were identified in the following databases: Scopus and Google Scholar. The relationship between the research's main concepts was illustrated to help visualize what the circular economy looks like in smart and sustainable cities. According to this study, implementing the circular economy in smart cities necessitates four major levers: 1. Technologies allow to set up an Infrastructure with garbage sensors connected to the network linking the stakeholders. The application of the platform made it possible to collect, communicate, share, and visualize the system's information in real-time and to ensure the monitoring and optimization of physical flows in a win-win perspective; 2. Good governance requires a shared vision, an integrated urban policy, stakeholder coordination, cross-sectoral coordination, and a stimulating legislative framework; 3. At the economic level, reverse value chain, circular design, business models based on the sharing economy, digital entrepreneurship, and data collection throughout the product life cycle should be embraced; 4. At the social level, consumer behavior and the incentive mechanisms for manufacturers to extend their social responsibility are determinants that need to be studied in depth. [ABSTRACT FROM AUTHOR]

Experimental studies in Behavior Analysis have consistently demonstrated the effect of reinforcement contingencies on the increase in behavioral variability in nonhumans and humans. Despite their regularity and generality, the data presented in the literature have given rise to a variety of interpretations, leading to controversies over how to account for reinforced behavioral variability. The present study systematized the literature about variability with the aim of identifying and characterizing these interpretations, their underpinnings, and the criticisms directed at them. We identified interpretations involving the notion of variation as an operant behavior or, at least, as an operant dimension of behavior, and interpretations that dismissed this notion in characterizing the increase in variability as a secondary effect of behavioral processes present in variation contingencies. Not all interpretations found were based on established empirical bases, and only some were commented on or criticized by authors in the area. [ABSTRACT FROM AUTHOR]

The goal of this research was to identify the most characteristic psychopathological symptomatology and type of aggression (expressive and instrumental) in individuals who presented a higher risk of violence in a sample of offenders. The sample consisted of 285 incarcerated males aged 20 to 67 years (M= 34.73, SD= 10.34) and it was divided into three groups according to violence risk (high, moderate, and low). The instruments used were the Symptom Checklist-90-R (SCL-90-R), the Instrumental and Expressive Aggression Questionnaire (CAIE) and the Self-Appraisal Questionnaire (SAQ). The results showed that, as violence risk increases, the levels of psychopathological symptomatology increase, as do expressive and instrumental aggressive behaviors, although psychoticism and expressive aggression best predicted belonging to the moderate- and high-risk groups. Therefore, moderate violence risk is sufficient to establish prevention and intervention measures in this population. [ABSTRACT FROM AUTHOR]

Type 2 diabetes mellitus is a worldwide public health problem associated with obesity and overweight. A strict diet is a critical part of the treatment, but it is common for patients to have difficulty adhering to it. The literature reports a variety of techniques increasing adherence, but there is not an evident a common factor among them. Objective. The present study sought to assess possible differences between two modalities of psycho-educational programs with differing levels of personalization. Method. The modalities were designed according to specific patients' needs and led to advancement along materials only when participants showed effective learning in each step. Eleven, randomly-assigned patients composed a personalized condition and ten a non-personalized one. Seven and five participants respectively completed the program, through a pretest-posttest design. Data collection included an adherence index scale and other physical records related to weight. Results. The main findings revealed that the difference between both modalities in the post-test was not statistically significant in any indicator. However, differences resulted significant between pre-test and post-test measures of the personalized intervention, with large effect sizes for most indicators. Discussion. Findings are discussed in terms of the program components likely to have made the difference, the benefits of the measures used, the experimental design, and the recommendations for entry-level diet adherence.

This study aimed to identify, synthesize, and evaluate the current state of research on the use of technology-based interventions in clinical psychology through 2017 as a recent innovative area of study. It was intended to provide a critical overview of trends in different tools and populations and identify future areas of interest. This paper focuses on studies published in psychological interventions in childhood, adolescents, adults, and geriatric populations using new technologies, including web-based intervention, virtual reality, augmented reality, mobile applications, and robotics, with particular attention to methodology. To achieve this aim, a systematic search was made in the ISI Web of Science for intervention, psychology, and the technological tools previously mentioned. The results of the study show that the use of information and communication technologies in psychology has been an innovative and growing field of study for the last 10 years. In total, 743 were included in this study. A growing trend has been observed in publications related to psychology and the use of technologies since 2007. Resea0rch topics were focused mainly on interventions on specific problems or disorders such as depression. The largest number of publications were found for the web-based intervention, in randomized clinical trials and applied to adults [ABSTRACT FROM AUTHOR]

This systematic review assesses if positive psychology interventions (PPI) are more effective than other active psychological interventions for increasing the well-being of depressed adults. A review of randomised trials that compared PPI to other active interventions was conducted. A systematic search was undertaken using PsycInfo, PubMed, EMBASE, Web of Science, Scopus, CINAHL, two trial registries, and a manual search. The outcomes were happiness and depression. Ten studies, totalling 1341 participants, were included in the review. The small effect sizes for depression (Hedge's g = 0.15) and happiness (Hedge's g = 0.20) favoured PPI but were not significant, indicating no difference between PPI and other active interventions for the outcomes. Heterogeneity was high mainly due to differences in trial implementation. Risks of bias ranged from moderate to high. The results should be interpreted with caution because of the small number of included studies, high heterogeneity, and presence of bias. Protocol Registration Number PROSPERO CRD42019152513.

The current study aimed to explore the public understanding of COVID-19 vaccines and the social representations emerging from a corpus of user-generated comments on YouTube videos posted during the year following the World Health Organization's declaration of the novel coronavirus as pandemic. We used Structural Topic Modelling to process the text and identified a 10-topic solution as the best to represent the corpus of text data. The exploration of the topics showed a complex landscape of social representations underlying a plurality of perspectives, which we interpreted as reflecting different users' needs to make sense of the unprecedented events. Implications for theory, future research, and intervention for health psychology and policy are discussed. [ABSTRACT FROM AUTHOR]

Many philosophers, psychologists, and lay folk associate volition with autonomy (actions are independent of an individual's environment) and free will (individuals originate their actions). Most behaviorists hold these views to be incompatible with behavior analyses. The present paper describes volition as interpreted by B. F. Skinner, Howard Rachlin, and Allen Neuringer. Skinner relates volition to positively reinforced operant behavior. That works because, like operants, voluntary actions are free, in the sense of not physically constrained; they affect their environments, often resulting in positive outcomes, and are sometimes unpredictable. Rachlin, while incorporating Skinnerian methods, interprets volition within his own Teleological Behaviorism framework. For Rachlin, reinforcement of an individual response is often incompatible with voluntary control, thereby disagreeing with Skinner. Responses are voluntary only when they are members of extended response patterns. Neuringer also begins with Skinner's operants, but argues that, under the control of reinforcing consequences, both voluntary actions and operant responses are sometimes predictable and other times "truly" unpredictable. Neuringer does not assume that environments determine voluntary actions, thereby disagreeing with Skinner and Rachlin. Taken together, the agreements and disagreements among these three behaviorists may help to shed light on the relationship between operants and volition. [ABSTRACT FROM AUTHOR]

Gastrointestinal bezoars in the pediatric age group have an unusual presentation, and their clinical manifestation is mainly associated with obstructive conditions of the gastrointestinal tract, and are generally made up of hair and food debris. In a smaller number, it has been seen that from its usual location, which is the stomach, bezoar structures could extend into the duodenum, jejunum, ileum, and even colon, giving the appearance of a "Rapunzel tail". We present the case of a 7-year-old girl with an atypical initial presentation of Rapunzel syndrome, secondary to a trichobezoar. The patient did not have previous psychiatric history, nor reports of any disturbance at school. She was admitted to the emergency room due to upper gastrointestinal bleeding and required a subsequent transfusion of blood products. During her hospitalization, an upper digestive endoscopy was performed, with the diagnosis of Rapunzel syndrome, in addition to the presence of two Forrest II-C, III gastric ulcers and severe erythematous gastritis in the region of the antrum and body. Medical treatment was started without success, for which the bezoar had to be surgically removed. Therefore, we want to point out the importance of deepening certain aspects such as the medical history and background in this type of patient, since it is a disorder linked to behavioral and mood alterations; likewise, remember the less frequent clinical symptoms such as upper gastrointestinal bleeding, but which in turn can be lethal if we don't act promptly. In the same way, the comprehensive approach with the support of the family and the intervention of psychology and/or psychiatry is vital to prevent recurrences. [ABSTRACT FROM AUTHOR]

Rationale: During operant conditioning, animals associate actions with outcomes. However, patterns and rates of operant responding change over learning, which makes it difficult to distinguish changes in learning from general changes in performance or movement. Thus, understanding how task parameters influence movement execution is essential. Objectives: To understand how specific operant task parameters influenced the repetition of future operant responses, we investigated the ability of operant conditioning schedules and contingencies to promote reproducible bouts of five lever presses in mice. Methods: Mice were trained on one of the four operant tasks to test three distinct hypotheses: (1) whether a cue presented concurrently with sucrose delivery influenced the pattern of lever pressing; (2) whether requiring animals to collect earned sucrose promoted the organization of responses into bouts; and (3) whether only reinforcing bouts where interresponse time (IRT) variances were below a target promoted reproducible patterns of operant behavior. Results: (1) Signaling reinforcer delivery with a cue increased learning rates but resulted in mice pressing the lever in fast succession until the cue turned on, rather than executing discrete bouts. (2) Requiring mice to collect the reinforcer between bouts had little effect on behavior. (3) A training strategy that directly reinforced bouts with low variance IRTs was not more effective than a traditional fixed ratio schedule at promoting reproducible action execution. Conclusions: Together, our findings provide insights into the parameters of behavioral training that promote reproducible actions and that should be carefully selected when designing operant conditioning experiments.

Traumatic brain injuries (TBIs) affect more than 10 million patients annually worldwide, causing long-term cognitive and psychosocial impairments. Frontal lobe TBIs commonly impair executive function, but laboratory models typically focus primarily on spatial learning and declarative memory. We implemented a multi-modal approach for clinically relevant cognitive-behavioral assessments of frontal lobe function in rats with TBI and assessed treatment benefits of the serotonin-norepinephrine reuptake inhibitor, milnacipran (MLN). Two attentional set-shifting tasks (AST) evaluated cognitive flexibility via the rats' ability to locate food-based rewards by learning, unlearning, and relearning sequential rule sets with shifting salient cues. Adult male rats reached stable pre-injury operant AST (oAST) performance in 3–4 weeks, then were isoflurane-anesthetized, subjected to a unilateral frontal lobe controlled cortical impact (2.4 mm depth, 4 m/sec velocity) or Sham injury, and randomized to treatment conditions. Milnacipran (30 mg/kg/day) or vehicle (VEH; 10% ethanol in saline) was administered intraperitoneally via implanted osmotic minipumps (continuous infusions post-surgery, 60 μL/h). Rats had a 10-day recovery post-TBI/Sham before performing light/location-based oAST for 10 days and, subsequently, odor/media-based digging AST (dAST) on the last test day (26-27 days post-injury) before sacrifice. Both AST tests revealed significant deficits in TBI+VEH rats, seen as elevated total trials and errors (p < 0.05), which generally normalized in MLN-treated rats (p < 0.05). This first simultaneous dual AST assessment demonstrates oAST and dAST are sufficiently sensitive and robust to detect subtle attentional and cognitive flexibility executive impairments after frontal lobe TBI in rats. Chronic MLN administration shows promise for attenuation of post-TBI executive function deficits, thus meriting further investigation. [ABSTRACT FROM AUTHOR]

Triangulating corpus linguistic approaches with other (linguistic and non-linguistic) approaches enhances "both the rigour of corpus linguistics and its incorporation into all kinds of research" (McEnery & Hardie, 2012: 227). Our study investigates an important area of mental health research: the experiences of those who hear voices that others cannot hear, and particularly the ways in which those voices are described as person-like. We apply corpus methods to augment the findings of a qualitative approach to 40 interviews with voice-hearers, whereby each interview was coded as involving 'minimal' or 'complex' personification of voices. Our analysis provides linguistic evidence in support of the qualitative coding of the interviews, but also goes beyond a binary approach by revealing different types and degrees of personification of voices, based on how they are referred to and described by voice-hearers. We relate these findings to concepts that inform therapeutic interventions in clinical psychology. [ABSTRACT FROM AUTHOR]

Background. Previous reviews have concluded that whilst mindfulness-based interventions reduce PTSD symptoms through fear extinction and cognitive restructuring, further research is needed. Objective. The aim of this report is to systematically review existing literature about the association between standardized mindfulness-based interventions and PTSD with the aim of identifying implications for practice and recommendations for future research. Method. The CINAHL Complete, PsycINFO, Medline, and PsycArticles databases were searched, looking for full-text articles from 2018 up to march 2022. Results. There was a significant improvement in PTSD symptoms in MBCT participants, even if some experienced a high increase at baseline. MBSR participants with moderate to severe trauma symptoms showed a greater reduction in symptoms whereas mild trauma symptoms at baseline showed slightly higher symptomatology at the end of treatment. Discussion and conclusion. From the results, MBCT, MBSR, and their variations seem to tackle different domains of the diagnosis. Whilst MBSR is associated with improvements in terms of attentional difficulties, MBCT facilitates the connection between dysfunctional cognitive concepts and avoidant behaviours that maintain the symptomatology. Nevertheless, the active components of MBCT or MBSR that have an impact on symptom reduction are undetermined. Future studies will be enhanced by monitoring the change in underlying mechanisms attached to the practice of mindfulness through outcome measurements, among other considerations.

Humor has a rich and wide history; in recent years it has started to receive greater attention due to its benefits for health and well-being. Recent works have highlighted that this construct can be a useful tool in the work context. Nevertheless, in the literature there is no record of a validated measure to assess humor at work in a sample of Portuguese workers. The main aim of this study was to fill this gap, by contributing to the adaptation and validation of the Humor Styles Questionnaire (HSQ). The specific objectives defined were related to the assessment of the: (a) factor validity of the HSQ indicators; (b) convergent validity of the dimensions of this instrument; (c) criterion validity, using concepts such as job satisfaction, affective commitment, continuance commitment, work engagement, emotional exhaustion, and job performance; and (d) reliability. A sample of 201 workers, 52% females and 48% males, was collected. The obtained results showed that the model with four-correlated factors achieved a better fit. Also, there was evidence of factor validity and reliability, however some results, particularly at the convergent validity and criterion validity level, did not meet the expectations. The adaptation and validation of the HSQ is crucial to understand which outcomes can emerge from the different humor styles, as well as it contributes for the development of interventions linked to humor, research has shown that positive psychology interventions promote desirable effects for workers.

The recent study aimed to investigate the relationship between negative life events and psychological distress in adults with acquired physical disability. Purposive sampling technique was used to collect sample of 112 participants form Rawalpindi Hospital. Traumatic Experience Checklist (Nijenhuis et al., 2002) was used to measure the potentially traumatizing negative life events and Kessler’s psychological distress scale (Kessler, 2002) was used to check the level of psychological distress were used in this study. Findings of the study suggested that there was a significant positive relationship between negative life events and psychological. Negative life event was significant predictor of psychological distress. The authors conclude that the evidence supports positive psychology interventions in hospital to combat the effects of negative life events through the positive psychological states of optimism, hope, and gratitude. The specific clinical implications for practicing counselors and educational settings are suggested. [ABSTRACT FROM AUTHOR]

The Perseverance rover, Mars 2020 mission, landed on the surface of the Jezero crater, on 18 February 2021. This Martian crater is suspected to have hosted a paleolake as evidenced by the numerous detections of aqueously altered phases and thus is a promising candidate for the search for past Martian life. The SuperCam instrument, a collaboration by a consortium of American and European laboratories, plays a leading role in this investigation, thanks to its highly versatile payload providing rapid, synergistic, fine‐scale mineralogy, chemistry, and color imaging. After its landing, the first measurements of Martian targets with the infrared spectrometer of SuperCam (IRS) showed new instrumental behaviors that had to be characterized and calibrated to derive unbiased science data. The IRS radiometric response has thus been calibrated using periodic observations of the Aluwhite SuperCam Calibration Target (SCCT). Parasitic effects were understood and mitigated, and the instrumental dark and noise are characterized and modeled. The reflectance calibrated data products, provided periodically on the NASA Planetary Data System, are corrected for the main instrumental features. This radiometric calibration allowed us to study the 2.5 μm absorption band, which has been discovered in the Séítah unit and is associated with phyllosilicates‐carbonates mixtures. Plain Language Summary: This paper is an instrumental investigation of the infrared spectrometer (IRS) portion of the SuperCam instrument on the Mars Science Laboratory Perseverance rover. Work performed prior to and during flight operations enabled the derivation of a proper instrumental response suitable for calibration of infrared point spectra of rocks and soils observed along the rover traverse. The paper describes development of a full data reduction pipeline in which the radiometric response, sensitivity of the IRS electronic board to temperature, and electromagnetic interference artifacts were removed. A companion paper (Mandon et al., 2022, https://doi.org/10.1029/2022JE007450) investigates the IRS data set through Sol 379 in more detail. Here, we specifically explore the 2.5 μm band attributed to carbonates in Séítah unit's phyllosilicate‐carbonates mixtures. We found that such mixtures likely have a low carbonate content, which may indicate low amounts of chemical alteration or an alteration by a carbon‐poor fluid. Key Points: The infrared spectrometer of SuperCam on Perseverance has been successfully flight calibrated using the onboard calibration targetsCalibration permitted to study the most challenging long wavelengths and thus to discover an absorption band at 2.5 μmStudy of the 2.3 and 2.5 μm absorption bands showed the Séitah unit has variable clay and carbonate mixtures with low carbonate content [ABSTRACT FROM AUTHOR]

Over the past thirty years, there has been a growing body of research investigating the efficacy of pedagogical interventions to enhance the historical literacy skills of primary and secondary school students. However, there exists no systematic review or meta-analysis summarising the impact of such research or the efficacy of interventions trialled. The purpose of this systematic review is to identify pedagogies that have a demonstrable effect on students' historical literacy skills, with a particular interest in those pedagogies that have a measurable positive effect on historical epistemological knowledge and skills. Findings of this review indicate that when a discrete historical epistemological knowledge or skill is targeted by a pedagogical intervention that utilises a discipline-specific scaffolded heuristic, there is greater likelihood of positive outcomes for student learning. However, the significant heterogeneity between studies, and the diversity in the comparisons being made by the included studies, make it difficult to identify the most effective intervention. This systematic review establishes the characteristic features of pedagogical historical literacy interventions from the available research reporting credible findings. [ABSTRACT FROM AUTHOR]

Introduction. The Doctor of Philosophy (PhD) degree is the zenith of academic achievement and the most prestigious of the doctoral programs, however there is a growing concern about the mental health issues among this graduating population. In the past decade Western research has presented a bleak depiction of mental health status of the trainee graduates with alarming titles in their editorials, which has lead both, academics and policy makers to implement several interventional strategies. Whereas mental health status of doctoral students from developing countries has not been addressed adequately and attempts to design interventional programs for this segment of population are quite limited. Therefore aim of this trial study is to establish the efficacy of an indigenously designed intervention Lets Flourish Together for PhD scholars based upon positive psychology techniques to promote well-being and enhance flourishment. Methods and Analysis. The intervention comprises of eight components based on positive psychology techniques, to be delivered over a period of 8-weeks. 154 PhD scholars will be recruited from six universities of Pakistan showing moderate levels of psychological distress assessed during screening process (t0) through DASS-21, in a two-armed randomized controlled trial. Other assessments will take place at (t1) before the start of the intervention, (t2) a week after the intervention and (t3) following a month. The primary outcome measure of the study is DASS-21, whereas secondary outcomes are flourishment (Positive Psychotherapy Inventory), motivation (Motivation for PhD Studies), perceived social support (Multidimensional Scale of Perceived Social Support), time management skills (Time Management Questionnaire), extent of task delaying (Procrastination Scale), personality traits (Ten Item Personality Inventory), sleep quality (Jenkins Sleep Scale) and physical activity (Six-point Physical Activity Scale). Analysis of data will be based on intention-to-treat principles. Ethics and Dissemination. This trial has been approved by the Institutional Review Board of the Foundation University School of Science and Technology (FURC/IRB/Spring-2022/29). Results will be published in peer-reviewed journals and presented in conferences. Trial Registration. The trial is registered at the WHO Primary Trial Registry Platform through Chinese Clinical Trial Registry; ChiCTR2200063701, dated: 9-15-2022. This is protocol version 1, in case of any important protocol modification, trial registry will be updated. [ABSTRACT FROM AUTHOR]

Territories are in a constant struggle to attract tourists, investments and residents striving for differentiation by exploiting the unique local values, which hold the essence of each one of them. This distinction is critical, differentiating each territory from others, and improving their competitive edge to be chosen as a favorite destination (Bigne et al., 2000). The application of branding in destination management has been used in recent years to generate a distinctive and competitive identity for a place, and distinguish it from others. And to be truly effective, the perceptions that a territory brand inspires in visitors and residents must align with the destination's main assets and their presentation in marketing communication (Kotler and Gertner, 2002). In this sense, local products, such as wine and food, are valid levers that contribute to shaping the positioning and differential values of the territories. The purpose of this paper is to: a) Examine how advertising of different Denominations of Origin in the wine industry contributes to the image and positioning of the different regions, thus creating a distinct positioning and promoting the area's identity and values; b) Analyze the content, strategies, and communication messages of the Denominations of Origin (of wine) across Spain. Through content analysis, combined with discourse analysis of the advertising strategies of a significant sample of Denominations of Origin (66 campaigns), we seek to establish variables for analysis and categorization of objectives, strategies, and discursive constructions that brands develop in their communication policies. Among the main results to highlight, the group of brands under scrutiny focused on the characteristics of the product while other strategies highlighted the values of the territory as main positioning values, that is, they served to communicate key aspects of the territory.

Cocaine administration has been shown to produce immediate positive (rewarding) and subsequent negative (anxiogenic) effects in humans and animals. These dual and opposing affective responses have been more difficult to demonstrate with administration of methamphetamine (meth). While animal studies have reliably demonstrated the positive reinforcing effects of the drug, reports of negative aftereffects following acute exposure have been few in number and contradictory in nature. The current research was devised to assess the effects of acute meth using a runway model of self-administration that is uniquely sensitive to both the positive and negative effects of a drug reinforcer in the same animal on the same trial. Male rats were allowed to traverse a straight alley once a day for 16 consecutive days/trials where entry into the goal box resulted in a single IV injection of meth (0.25, 0.5 or 1.0 mg/kg/inj.). The chosen doses were confirmed to be psychoactive as they produced dose-dependent increases in motoric/locomotor activation in these same subjects. The results demonstrated a U-shaped dose-response curve for the reinforcing effects of meth in that the intermediate dose group (0.5 mg/kg) produced the strongest approach behavior in the runway. Unlike other psychomotor stimulants, like cocaine, animals running for IV meth exhibited no evidence of any significant approach-avoidance behaviors reflective of the drug's negative anxiogenic effects. These results suggest that the abuse potential for meth is likely higher than for other shorter-acting psychomotor stimulants and reaffirms the utility of the runway procedure as a screen for a substance's abuse potential.

Scholars conducting cross-cultural research in mental health often import intervention programs found to be efficacious in one social context (e.g., Western) and directly implement them in other contexts (e.g., African and Asian) without recourse to the sociocultural disparities between the target populations and the theoretical foundations of the constructs and principles underpinning the intervention programs. Such efforts mistakenly assume that positive psychology interventions (PPIs), most of which were developed from Western perspectives and assumed individualistic cultural orientation and value systems, operate equally across all contexts. Drawing on the extant literature and on insights from designing, implementing, and evaluating group-based (mental) health behavior change intervention programs across several communities in Ghana, we discuss some sociocultural, theoretical, and methodological issues that can significantly constrain the design, uptake, and effectiveness of PPIs in the rural, low literate, socioeconomically disadvantaged, highly collectivistic context of Ghana, and sub-Saharan Africa more generally. In all illustrations, we offer suggestions to guide the design and implementation processes to ensure culturally appropriate, highly acceptable, and potentially effective intervention programs. We argue that PPIs can be potentially fructuous in the sub-region when adapted to, or embedded in, the cultural values of the target population and tailored to the needs, capacities, and circumstances of participants.

The use of theory in health behavior change interventions has been recently questioned with mixed results found for theory-based intervention effectiveness. But theory testing in intervention depends on not only theoretical assumptions, but on auxiliary assumptions too. Specifically, auxiliary assumptions are required to traverse the distance from nonobservational terms in theories and observational terms at the level of the empirical hypotheses in interventions. We believe intervention failures are often due to flaws in auxiliary assumptions rather than assumptions at the theoretical level. We use the theory of planned behavior to illustrate how the consideration of these auxiliary assumptions is important to appraise the effectiveness of interventions informed by theory. We hope that bringing attention to the importance of auxiliary assumptions provides a more nuanced and accurate appraisal of theory utility. [ABSTRACT FROM AUTHOR]

Serial reversal-learning procedures are simple preparations that allow for a better understanding of how animals learn about environmental changes, including flexibly shifting responding to adapt to changing reinforcement contingencies. The present study examined serial reversal learning with humans by arranging both midsession and variable contingency reversals across two experiments. We also examined the effects of extinction by adding nonreinforced trials at the end of later sessions and provided the first evaluation of effects of win-stay/lose-shift versus counting strategies on accuracy and response latency of humans' reversal-learning performance. In each experiment, responding tracked contingency reversals, primarily with participants using either win-stay/lose-shift or counting strategies. Introducing variable reversal points in the second experiment resulted in near-exclusive win-stay/lose-shift responding among participants and eliminated counting of trials. Each experiment also revealed an immediate shift from S2 to S1 after experiencing extinction during the initial test trial, indicating resurgence of the initial response through a win-stay/lose-shift response pattern. Therefore, the present study replicates and extends prior findings of a win-stay/lose shift response pattern in situations of greater uncertainty. These findings suggest that differences in environmental certainty induce qualitatively different decision-making strategies. [ABSTRACT FROM AUTHOR]

Recent police brutality and related violence against Black people, coupled with the COVID-19 pandemic, has further evidenced the disproportionate impact of systemic racism in our institutions and across society. In the United States, the alarming mortality rates for Black people due to police violence and COVID-19 related deaths are clear demonstrations of inequities within a long history of disparate outcomes. In understanding systemic racism, it is essential to consider how it is embedded within society and across socio-ecological levels. The Social-Ecological Model (SEM) is used to examine conditions within the environment that maintain systemic racism, including within our field and discipline. A behavioral-community approach for examining racism aids in determining points of intervention across multiple ecological levels that may contribute to behavior change, including with behaviorists. The science of behavior is well-suited to help examine the contingencies governing behaviors within and across systems, which is pivotal for addressing operant behaviors to influence long-term behavior change. This paper calls on the behavioral community to address systemic racism within our environments and systems of influence to contribute to a more equitable community. Systemic racism, including within the context of anti-Blackness, is examined by considering behavior change strategies that can be supported by behaviorists across socio-ecological levels. Tools for collaborative action are provided to support behaviorists in demonstrating the skills needed across a continuum of behaviors from allyship to anti-racism to actively address systemic racism.
