This study sought to evaluate the potential anxiolytic or antidepressant effects of a synbiotic diet in an avian model that presents homologies with treatment-resistant depression. In addition, we sought to evaluate the potential interaction of a synbiotic diet combined with select doses of ketamine. Socially raised Black Australorp chicks were given either standard or synbiotic feed for 7 days. At 7 days posthatch, chicks from each feed condition were administered either 0, 5, or 10 mg/kg/ml ketamine 15 min before a 90-min isolation stressor, which elicits distress vocalizations (DVocs) that temporally represent a panic-like phase followed by a depression-like phase. Saline-treated chicks given the synbiotic diet displayed significantly higher DVoc rates in the depression-like phase compared with saline-treated animals in the standard feed condition, indicative of attenuation of behavioral despair [F(1,22) = 5.45, P < 0.05]. Similarly, in the standard diet condition, ketamine 10 mg/kg produced elevated DVoc rates; however, under the synbiotic diet, both doses of ketamine produced a suppression of DVoc rates in the depression-like phase. These findings suggest that a synbiotic diet produces antidepressant-like effects in the model and a possible negative interaction between synbiotics and ketamine. While preliminary, the findings suggest the concurrent use of pre- and probiotic supplements and ketamine may produce contradictory effects and warrant further investigation.","PeriodicalId":8832,"journal":{"name":"Behavioural Pharmacology","volume":"36 7","pages":"526-533"},"PeriodicalIF":1.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144991389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this emotional amplification effect has not been consistently observed in tasks where observers summarize other crowd features, such as the number of faces. This study aims to explore the attentional mechanisms underlying these inconsistent findings. To do so, we recruited 584 participants across four online experiments and employed an equivalence judgment task to assess participants' ability to estimate the number of emotional faces. In the task, participants determined whether the number of two types of facial expressions within a series of crowds was the \"same\" or \"different.\" Experiment 1 revealed that the number of emotional faces (angry and happy) was underestimated relative to neutral faces. Experiment 2 replicated this underestimation effect across different face types and exposure durations. Experiment 3 demonstrated that the emotional amplification effect may be caused by strong emotion contrasts within crowds. Experiment 4 confirmed that the underestimation of the number of emotional faces could be replicated in the numerosity estimation task with different instructions. Our findings suggest that people may strategically suppress attention to emotional faces to mitigate their emotional response. This study provides important empirical evidence to enhance our understanding of the cognitive processes underlying emotion perception and social behavior.","PeriodicalId":55433,"journal":{"name":"Attention Perception & Psychophysics","volume":" ","pages":"2223-2240"},"PeriodicalIF":1.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12331794/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144610413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lithium is one of the well-known drugs used for the alleviation of symptoms in different neuropsychiatric disorders such as depression and bipolar disorder. In this research, we evaluated the efficacy of several doses of lithium on behavioral changes induced by CUMS. Also, the expression level of brain-derived neurotrophic factor (BDNF) and glycogen synthase kinase-3 beta (GSK-3beta) in the prefrontal cortex was evaluated. CUMS was done using various unpredictable stressors for 14 days. Lithium was injected at the doses of 10, 30, and 50 mg/kg. Locomotor activity, anxiety-like behavior, pain perception, and depressive-like behavior were assessed using the open field test, the novelty-suppressed feeding test, the hot plate test, and the forced swim test, respectively. The results revealed that CUMS decreased locomotor activity, increased anxiety- and depressive-like behaviors, increased pain threshold, decreased climbing, decreased BDNF level, and increased GSK-3beta level in the prefrontal cortex. However, lithium dose-dependently restored all these effects. In control rats, lithium (50 mg/kg) decreased locomotion and GSK-3beta expression levels. In conclusion, the results suggested that deleterious effects of CUMS may be mediated via BDNF and GSK-3beta in the prefrontal cortex, and lithium via suppressing GSK-3beta and upregulating BDNF expression levels in the prefrontal cortex can restore CUMS effects.","PeriodicalId":8832,"journal":{"name":"Behavioural Pharmacology","volume":" ","pages":"471-483"},"PeriodicalIF":1.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144759037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adaptation-based approaches have uncovered a few specific abilities enhanced by particular adversity exposures. Yet, for a field to grow, we must not dig too deep, too soon. In this paper, we complement confirmatory research with principled exploration. We draw on two insights from adaptation-based research: 1) enhanced performance manifests within individuals, and 2) reduced and enhanced performance can co-occur. Although commonly assumed, relative performance differences are rarely tested. To quantify them, we need a wide variety of ability measures. However, rather than using adaptive logic to predict which abilities are enhanced or reduced, we develop statistical criteria to identify three data patterns: reduced, enhanced, and intact performance. With these criteria, we analyzed data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development to investigate how adversity shapes within-person performance across 10 abilities in a cognitive and achievement battery. Our goals are to document adversity-shaped cognitive performance patterns, identify drivers of reduced performance, identify sets of \"intact\" abilities, and discover new enhanced abilities. We believe principled exploration with clear criteria can help break new theoretical and empirical ground, remap old territory, and advance theory development.","PeriodicalId":11265,"journal":{"name":"Development and Psychopathology","volume":" ","pages":"1859-1876"},"PeriodicalIF":3.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142281921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One high-risk pathway involves an interaction between heritable trait impulsivity and emotion dysregulation (ED). Together, these confer increased vulnerability to nonsuicidal self-injury (NSSI), suicide ideation (SI), and suicide attempts (SAs). Previous work, however, has been limited to homogeneous samples. We extend the Impulsivity × ED hypothesis to a more diverse sample of adolescents (N = 344, ages 12-15 at Baseline, 107 males and 237 females) who were treated for major depression and assessed four times over two years. In multilevel models, the impulsivity × ED interaction was associated with higher levels and worse trajectories of NSSI, SI, and SAs. As expected, stressful life events were also associated with poorer trajectories for all outcomes, and NSSI was associated with future and concurrent SI and SAs. These findings extend one developmental pathway of risk for self-harming and suicidal behaviors to more diverse adolescents, with potential implications for prevention.","PeriodicalId":11265,"journal":{"name":"Development and Psychopathology","volume":" ","pages":"1742-1755"},"PeriodicalIF":3.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142567819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
