The present study therefore assesses the effects of a simple(est) physical effort (i.e., isometric handgrip) on temporal processing with concurrent time reproduction/production and handgrip tasks. Isometric handgrip can induce physical arousal, thereby accelerating time and leading to overestimation when sensory timing is under physical effort, but underestimation when the motor timing is under physical effort (i.e., arousal hypothesis). Alternatively, handgrip may directly impair temporal processing given the potential competition for attention, resulting in underestimated durations when sensory timing is under physical effort and overestimated durations when motor timing is under physical effort (i.e., competition hypothesis). Our data collected in 2023-2024 revealed that high physical effort increased estimated durations in the time reproduction task with concurrent sensory timing and handgrip (Experiments 1-2) but decreased estimated durations in the time production task with concurrent motor timing and handgrip (Experiment 4), supporting the arousal hypothesis. Two additional experiments ruled out some alternative accounts (e.g., response bias). In Experiment 3, the handgrip effect was absent when time was cued, instead of being experienced, under handgrip. In Experiment 5, the handgrip effects of sensory timing and motor timing canceled each other out (i.e., the El Greco effect) when both sensory timing and motor timing were under handgrip. Overall, these findings suggest that physical effort distorts perceived time, with increased arousal likely contributing to the acceleration of temporal processing.

This study explored community perceptions of male IPV victimization in an informal settlement in Nairobi, Kenya. We conducted 12 focus group discussions (FGDs) with 118 ever-married participants (59 men and 59 women), divided into 6 FGDs for each gender. We performed thematic analysis using <i>NVivo</i> software. This article presents three main themes that emerged during data analysis: (a) triggers, (b) manifestations, and (c) consequences/effects of IPV against men. Both male and female participants perceived male IPV victimization as a significant concern in the community. The poor living conditions, coupled with alcohol use, seemed to be major underlying factors, often forming the basis of spousal conflict. Emotional abuse, including denial of basic needs, acts of humiliation, and coercive control, were the most frequently cited forms of violence. The consequences of what was considered IPV against men affected victims and their families including the violent female spouses, children, and the society at large. These effects upset the health, economic, and social spheres of life with some retriggering male IPV, thus creating a vicious cycle of abuse. Notably and of concern, IPV against women was highlighted as a consequence of male victimization. Although we set out to explore community perceptions, study participants openly shared their experiences of male IPV perpetration and victimization. These findings underscore the importance of recognizing men as potential victims of IPV and contextualizing IPV prevention strategies targeting the urban poor with the goal of designing and implementing policies and interventions that address IPV holistically.</p>","PeriodicalId":16289,"journal":{"name":"Journal of Interpersonal Violence","volume":" ","pages":"5036-5071"},"PeriodicalIF":2.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12504788/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142750965","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}

Scholars have argued that in contemporary Western societies, the concept is expanding toward a broader understanding of violence, beyond its \"traditional\" usage in the context of crime and war. The current paper aims to generate empirical evidence that speaks to this question. We take the Netherlands as a case study and apply machine learning techniques to discourse on violence in 80,000 articles published in national newspapers between 2012 and 2021. Results show that the public discourse on violence in the Netherlands has a component that can be described as the familiar or \"traditional\" usage of the term violence-referring to violent political conflicts, or interpersonal violence such as child abuse. Beyond this, the term violence is associated with discourse on societal challenges. It appears in discourse on social media, political polarization, and social injustice faced by ethnic minorities, women, and the LGBT+ community. The later stages of the analysis demonstrated that the terms associated with social injustice in particular (e.g., \"racist\") become more closely associated with the concept of violence over time. In short, our findings support the notion that the collective understanding of violence in the Netherlands is developing toward a broader understanding of violence, beyond the context of crime and war.

The understudied strengths were identified in previous qualitative work as salient in the southeastern communities where the study took place. The sample was comprised of 357 adults recruited from community events in Tennessee. Their average age was 37.6 years (<i>SD</i> 15.6), and the sample was 65.8% female. They completed a survey with measures of 16 psychosocial strengths, polyvictimization, and a range of outcomes. Blockwise logistic regressions were conducted using subjective well-being and trauma symptoms as the outcome. Results indicated that positive emotion regulation was the best predictor of positive functioning after experiencing trauma. Polystrengths (an indicator of the breadth of a person's resilience portfolios), a sense of purpose, and social support received were also associated with better functioning after controlling for polyvictimization, other adversities, and demographics. In multivariate analyses, religious meaning-making and relational motivation were unexpectedly associated with worse outcomes. Most studies of emotion regulation only explore the regulation of negative emotions, such as distress and anger, but the capacity to regulate positive emotions shows promise for helping people overcome trauma.

Motivation, such as reward and punishment, has been widely recognized as a key factor influencing WM. Previous research has either examined the impacts of reward and punishment on the availability of WM resources separately or focused solely on the effects of reward on resource allocation. We posit that integrating these effects into a single study is essential for a comprehensive understanding of their interplay. To this end, we conducted three experiments using a delay estimation task, combined with the Target Confusability Competition model, to systematically investigate how reward and punishment affect the availability and allocation of WM resources. In Experiment 1, participants memorized the orientations of two arrows, each associated with reward or punishment cues. In Experiments 2 and 3, participants encountered both reward and punishment cues within the same trial, testing three hypotheses about resource allocation: reward dominance, punishment dominance, and no difference. Results from Experiment 1 revealed that reward and punishment equally enhanced the availability of WM resources. In Experiment 2, which was the first to integrate rewards and punishments within the same trial, reward prioritized the allocation of WM resources over punishment. Eye-tracking data from Experiment 3 indicated that this effect was driven by greater attentional focus on reward targets, which led to more WM resource allocation. We provide novel evidence that reward outweighs punishment in WM resource allocation.

In three experiments, participants searched for a pointed-at target object that was embedded among distractor objects arranged with different spatial densities while eye movements were tracked. Participants searched in a restricted region surrounding the position they perceived as pointed-at. However, the sizes of the searched regions depended considerably on the density of the search display, refuting the hypothesis that pointing gestures strictly mark the to-be-searched region. In addition, participants sometimes scanned objects that they would not even consider as pointed-at. We suggest that a flexible time-correlated criterion or a hybrid spatiotemporal criterion determines the sizes of the searched region.

Here we explore whether the capacity of visual imagery (as yet unknown) is similar to the known capacity limits of visual working memory (VWM) and visual short-term memory (VSTM). Experiment 1 explored capacity limits in imagination, VWM, and VSTM using a novel paradigm that, for the first time, provided estimates of capacity across these tasks. Imagination capacity was lower than that of VWM and VSTM. Experiments 2-4 eliminated alternative explanations of this capacity difference. Manipulating the time available to generate, update, and maintain an image (imagination task) or encode, update, and maintain an image (VWM task) did not influence performance in either task (Experiment 2). Manipulating the cue location and the size of the cued area had no specific influence on the imagination task (Experiment 3). Changing the test display (Experiment 4) showed that presenting all items at test (configural information) benefited VSTM performance, presenting a single item benefited VWM performance, and manipulating test display had no impact on imagination performance. In Experiment 5, increasing object complexity eliminated the difference between VSTM and imagination capacity; however, VWM capacity remained higher than that of imagery. For the first time, these experiments using analogous tasks demonstrate a difference in the observed capacities of VWM and imagery and provide the first measurable indication of the extent to which top-down (imagery), versus bottom-up activation of sensory systems (memory) supports the representation of perceptual stimuli.
