This study aims to investigate the glucose and insulin levels in individuals with stress related burnout, by assessing these metabolic markers in response to a standard oral glucose tolerance test (OGTT). 38 cases with burnout (13 men and 25 women) and 35 healthy controls (13 men and 22 women) in the age 24-55 were included in the study. The burnout group overall did not differ from healthy controls in glucose or insulin levels during the OGTT. However, the burnout cases who reported more severe burnout symptoms exhibited significantly higher levels of both glucose and insulin levels during the OGTT compared to burnout cases reporting lower severity of symptoms. Furthermore, the group of burnout cases who reported symptoms of depression exhibited higher insulin levels during OGTT compared to the burnout cases without depressive symptoms. The observed higher levels in the burnout cases with most severe symptoms indicate an increased diabetic risk in these patients and it may be of importance to follow glucose and insulin levels in individuals with more severe symptoms of burnout i.e. to perform an OGTT.","PeriodicalId":51173,"journal":{"name":"Stress-The International Journal on the Biology of Stress","volume":"28 1","pages":"2438699"},"PeriodicalIF":2.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142840205","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}

But how do repeated risky choices develop in early childhood when outcome probabilities are learned from description? Integrating previous findings from children's sampling processes in causal learning and adults' repeated choice behavior, we investigated repeated choices from 201 children aged 3 to 7 years and 100 adults in a child-friendly risky choice task. We expected young children to probability match and predicted that the perceived dependency between choices would shape the underlying choice process. However, the assumed cognitive processes derived from the causal learning and risky choice literature did not generalize to children's or adults' repeated risky choices when outcome probabilities were learned from graphical representations prior to making a decision. Moreover, choice behavior did not differ as a function of the perceived dependency between guesses. Instead, children broadly diversified choices, and switching between options dominated older children's choice behavior. Our results contribute to increasing evidence of childhood as a phase for heightened exploration and highlight the importance of considering the learning format when studying repeated choice across development.","PeriodicalId":48391,"journal":{"name":"Journal of Experimental Child Psychology","volume":"251 ","pages":"106126"},"PeriodicalIF":1.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142781489","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}

However, less is known about whether the nature of the relations between verbal and nonverbal systems and numerical cognition varies depending on the unique characteristics children bring into numerical learning. To better delineate these associations, we examined the association between verbal and nonverbal skills and symbolic numerical development in preterm-born (PTB; n = 93; <37 weeks of gestation) children and term-born children (n = 104). We showed that PTB preschoolers, as a group, were at a higher risk of falling behind on certain numerical tasks (cardinality) but not on others (counting). There was, however, significant individual variability within the groups. Verbal and nonverbal skills contributed to the variability of children's numerical performance but did so differentially across the full spectrum of gestational age. Specifically, verbal skills moderated the association between gestational age and symbolic number performance (cardinality). The relation between verbal and cardinality skills was stronger at higher gestational ages compared with lower gestational ages. In addition, at higher gestational ages, children more frequently used retrieval strategy and less often relied solely on finger counting for the cardinality task. Shifting the focus from group differences to understanding individuals and their unique developmental pathways may enhance our insight into the risk and protective factors underlying the variability observed in all children.","PeriodicalId":48391,"journal":{"name":"Journal of Experimental Child Psychology","volume":"251 ","pages":"106128"},"PeriodicalIF":1.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142773681","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}

However, the effects of HRC for this setting have not been investigated.Methods: Sixteen participants were recruited. Four HRC modes, no cue, with cue, unreliable, and manual control were included. Three categories of dependent variables were measured: (1) spine kinematics (L5/S1, L1/T12, and T1/C7), (2) pupillary activation data, and (3) subjective measures such as perceived workload, robot-related anxiety, and negative attitudes towards robotics.Results: HRC reduced anxiety towards the cobot, decreased joint angles and angular velocity for the L5/S1 and L1/T12 joints, and reduced pupil dilation, with the \"with cue\" mode producing the lowest values. However, unreliability was detrimental to these gains. In addition, HRC resulted in a higher flexion angle for the neck (i.e., T1/C7).Conclusion: HRC reduced the physical and mental workload during the simulated pollination task. Benefits of the additional cue were minimal compared to no cues. The increased joint angle in the neck and unreliability affecting lower and mid back joint angles and workload requires further investigation.Application: These findings could be used to inform design decisions for HRC frameworks for agricultural applications that are cognizant of the different effects induced by HRC.","PeriodicalId":56333,"journal":{"name":"Human Factors","volume":" ","pages":"100-114"},"PeriodicalIF":2.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141162827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little research has focused on non-offending partners' wellbeing and relationships with persons with sexual offense histories leading up to and following acts of sexual aggression. Non-offending partners may be secondary victims of their partners' offenses in managing psychological difficulties (e.g., guilt, shame), social stigma and isolation, fear for their safety, or difficulties in their romantic relationships resulting from their partners' sexual offenses, often with minimal supports. The current study examined key correlates of individual and interpersonal adjustment among 207 non-offending partners of individuals with histories of sexual offenses who were residing in Canada (n = 36) or the United States (n = 171). Findings indicate that positive changes due to the offense (i.e., improved finances), self-esteem, interpersonal adjustment, instrumental support, lower levels of acceptance, and humor positively predicted individual adjustment. Interpersonal adjustment was predicted by trust, intimacy, partner's stress communication, and problem-focused and emotion-focused common dyadic coping. Findings highlight the need for services for non-offending partners, including interventions that address self-esteem and practical difficulties resulting from the offense, and couples therapy to address trust issues, intimacy concerns, and shared coping with stressors related to the offense.","PeriodicalId":21828,"journal":{"name":"Sexual Abuse: A Journal of Research and Treatment","volume":" ","pages":"58-87"},"PeriodicalIF":2.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11626856/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89719559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Emphasis was on possibilities to modify the timescale of this process.Background: Interactions with virtual objects are commonplace in settings like teleoperation, rehabilitation, and computer-aided design. These objects are quickly integrated into the operator's body schema (embodiment). Less is known about how long such embodiment lasts. Understanding the dynamics of this process is crucial because different applied settings either profit from fast or slow disembodiment.Method: To induce embodiment, participants moved a 2D virtual hand through operating a computer mouse or touchpad. After initial embodiment, participants either stopped or continued moving for a fixed period of time. Embodiment ratings were collected continuously during each trial.Results: Results across all experiments indicated that embodiment for the virtual hand gradually increased during active use and gradually decreased after stopping to use it. Disembodiment unfolded nearly twice as fast as embodiment and showed a curved decay pattern. These dynamics remained unaffected by anticipation of active control that would be required in an upcoming task.Conclusion: The results highlight the importance of continuously experiencing active control in virtual interactions if aiming at inducing stable embodiment of a virtual object.Application: Our findings suggest that applications of virtual disembodiment such as virtual tools or interventions to affect a person's body representation critically depend on continuous updating of sensorimotor experience. However, if switching between virtual objects, for example, during teleoperation or video gaming, after-effects are unlikely to affect performance.","PeriodicalId":56333,"journal":{"name":"Human Factors","volume":" ","pages":"115-140"},"PeriodicalIF":2.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11626855/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141322138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is thus important to identify factors that influence men's decisions to override direct refusals in these situations. Presently, we administered first-person vignettes depicting a prototypical hookup wherein the woman refuses the man's attempt to escalate intimacy. Using a national sample of emerging adult men (N = 420), we found that they on average did not completely rule out coercive or forcible tactics, but those elevated on rape myth acceptance, hypermasculinity, and psychopathy were uniquely at risk of assault when controlling for several other traits known to correlate with rape. Participants also reported being likelier to use coercive sexual practices when refusals occurred at higher levels of sexual intimacy already attained. Notably, diagnostic analyses revealed that a subset of men had a disproportionate influence on the regression estimates, and that these men were not only elevated across a range of assault-relevant traits, but also endorsed higher likelihoods of using coercion and force in the face of female sexual refusal. Although removal of these cases did not substantively alter the results, exploratory analyses revealed that these individuals responded differently to situational factors in ways that suggested sexual opportunism. Theoretical and practical implications of these findings are discussed.","PeriodicalId":21828,"journal":{"name":"Sexual Abuse: A Journal of Research and Treatment","volume":" ","pages":"88-118"},"PeriodicalIF":2.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141976690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
