In light of the adult model of a hemispheric asymmetry of global and local processing, we compared children (M age = 8.4 years) to adults in a global-local reaction time (RT) paradigm. Hierarchical designs (large shapes made of small shapes) were presented randomly to each visual field, and participants were instructed to identify either the global or the local level in each of two blocks. We obtained evidence of a global-local processing asymmetry, with stronger effects for children than for adults. In both children and adults, responses were faster and more accurate for global identification in the right hemisphere and for local identification in the left hemisphere. Similarly, a significant asymmetry of global and local interference was obtained in children but not in adults. Interference reflects the RT cost of conflicting information at the nonattended level. For example, local interference indicates the degree to which inconsistency at the local level slows global identification. Stronger evidence for lateralized processing in children is discussed within the framework of increasing interhemispheric transfer. That is, as interhemispheric transfer increases, cost of presentation to the nonpreferred hemisphere (e.g., local identification in the right hemisphere) is reduced. 相似文献

An initial study found that Deaf participants have a different definition of a date than the Traditional Sex Script (TSS). In the TSS, the man is viewed as the initiator who pushes for sex and the woman is expected to limit sex if they do not want to have intercourse; neither of these ideas were included in Deaf participants’ responses when asked what happens on a typical date. These findings may relate to early experiences in childhood. At an early age, hearing children are exposed to the TSS through popular culture. Deaf children are not exposed to these cues at the same level because of their lack of communication access. Here we compare Deaf college students to hearing college students to further investigate these issues using a more quantitative design. 相似文献

Recent work in cognitive and computational neuroscience depicts human brains as devices that minimize prediction error signals: signals that encode the difference between actual and expected sensory stimulations. This raises a series of puzzles whose common theme concerns a potential misfit between this bedrock informationtheoretic vision and familiar facts about the attractions of the unexpected. We humans often seem to actively seek out surprising events, deliberately harvesting novel and exciting streams of sensory stimulation. Conversely, we often experience some wellexpected sensations as unpleasant and to-be-avoided. In this paper, I explore several core and variant forms of this puzzle, using them to display multiple interacting elements that together deliver a satisfying solution. That solution requires us to go beyond the discussion of simple information-theoretic imperatives (such as 'minimize long-term prediction error') and to recognize the essential role of species-specific prestructuring, epistemic foraging, and cultural practices in shaping the restless, curious, novelty-seeking human mind. 相似文献

The deadliest U.S. school shooting to date, occurring on February 14, 2018 at Marjory Stoneman Douglas High School in Parkland, Florida serves as a powerful reminder that school violence is ever present. Addressing school violence, however, has been an elusive endeavor. The purpose of this review is to provide a historical examination of United States intentional mass school shootings in the 20th and 21st centuries. In addition, implications for students, schools, and society are discussed in light of policy and legislative initiatives as well as school-based prevention and intervention tiered models of support, such as positive behavior interventions and supports (PBIS). 相似文献

Firearm violence in United States has been a persistent concern for decades particularly in light of mass shootings. Firearm violence is increasingly viewed as a public health crisis, and results in a heavy financial burden to society. In light of the continuous challenges associated with firearm violence, limited research in the area, it is necessary to examine current trends regarding firearm deaths and injuries. Extant data from the U.S. Department of Health and Human Services, Centers for Disease Control and Prevention, Web-based Inquiry Statistics Query and Reporting System fatal and nonfatal injury reports were used for this study. Available data were examined in light of age groups across the life span, region, gender, and minority status for both fatalities and injuries related to firearms. Strategies for reducing firearm fatalities, particularly among children and youth, are also discussed. 相似文献

Islamist extremism is often explained by the suffering endured by Muslims in Islamic countries as a result of Western‐led wars. However, many terrorist attacks have been carried out by European Muslims with no personal experiences of war. Across two studies among Danish Muslims, we tested if what we call “victimization‐by‐proxy processes” motivate behavioral intentions to commit acts of violence. We used Muslim identification, perceived injustice of Western foreign policies, and group‐based anger to predict violent and nonviolent behavioral intentions. More importantly, we compared path models of Danish Muslims from conflict zones with those without direct personal experience of Western‐led occupation. We found similar effects among the participants in each category, that is, vicarious psychological responses mimicked those of personally experienced adversity. In fact, participants born in Western Europe were, on average, more strongly identified with Muslims, more likely to perceive Western foreign policy as more unjust, reported greater group‐based anger, and were more inclined to help Muslims both by nonviolent and violent means. 相似文献

Social rejection is a powerful negative emotional experience, yet rejected people often appear stoic and unmoved. That is, their macroexpressions of emotion are not accurate reflections of their emotional states. Yet, there is reason to believe that rejected people exhibit involuntary microexpressions of negative emotion. We contrasted people's macroexpressions of emotion with their microexpressions subsequent to an acceptance or rejection experience. Observers coded microexpressions after being trained with the Micro Expression Training Tool. Rejected participants expressed more sad and angry microexpressions than did accepted participants. This research demonstrates that socially rejected people display negative microexpressions that are detectable by observers trained in the Micro Expression Training Tool. 相似文献

Emotion regulation may influence psychological responses to exercise. We examined whether the emotion regulation strategies, cognitive reappraisal and distraction, influenced psychological state and prefrontal cortex oxygenation during endurance exercise. Twenty-four endurance runners ran for 90 min at 75–85% maximum heart rate in three separate sessions with no instruction or with instructions to use cognitive reappraisal or distraction. Participants rated their emotional arousal, emotional valence, and perceived exertion before, every 30 min during, and after exercise. Functional near-infrared spectroscopy quantified changes in prefrontal cortex oxygenation. Participants felt lower emotional arousal and physical exertion when instructed to utilize cognitive reappraisal than when given no emotion regulation instruction. Such responses to distraction did not differ from the other conditions. Emotion regulation strategies did not influence emotional valence or prefrontal cortex oxygenation. Participants’ analytical interpretation of the cognitive reappraisal instruction could contribute to small effect sizes and limited effects. Further research should determine contexts under which emotion regulation strategies most benefit endurance exercise experience. 相似文献
