Few studies have examined rates of mental health problems among special duty military personnel, who often have frequent deployments and high exposure to operational stressors and trauma. The current study examined the severity and rates of positive screening for posttraumatic stress, depression, and insomnia among 194 U.S. Air Force pararescuemen (PJs) in the active duty (AD) and National Guard/Reserve (NG/R) components. Overall estimated rates were 11.6% for probable posttraumatic stress disorder (PTSD), 1.6% for probable depression, and 16.1% for clinical insomnia. PJs in the NG/R reported significantly more severe posttraumatic stress symptoms (F(1, 162) = 10.031, p = .002, partial η2 = .058) and were approximately twice as likely to screen positive for probable PTSD (8.5% vs. 19.1%; χ2[1] = 3.679, p = .055). No differences in the rate or severity of depression or insomnia symptoms were found. Rates of positive screens are comparable to or lower than previously published rates among military personnel. 相似文献

This paper examines the first moments of the emergence of “psychometrics” as a discipline, using a history of the Binet–Simon test (precursor to the Stanford–Binet) to engage the question of how intelligence became a “psychological object.” To begin to answer this, we used a previously-unexamined set of French texts to highlight the negotiations and collaborations that led Alfred Binet (1857–1911) to identify “mental testing” as a research area worth pursuing. This included a long-standing rivalry with Désiré-Magloire Bourneville (1840–1909), who argued for decades that psychiatrists ought to be the professional arbiters of which children would be removed from the standard curriculum and referred to special education classes in asylums. In contrast, Binet sought to keep children in schools and conceived of a way for psychologists to do this. Supported by the Société libre de l'étude psychologique de l'enfant [Free society for the psychological study of the child], and by a number of collaborators and friends, he thus undertook to create a “metric” scale of intelligence—and the associated testing apparatus—to legitimize the role of psychologists in a to-that-point psychiatric domain: identifying and treating “the abnormal”. The result was a change in the earlier law requiring all healthy French children to attend school, between the ages of 6 and 13, to recognize instead that otherwise normal children sometimes need special help: they are “slow” (arriéré), but not “sick.” This conceptualization of intelligence was then carried forward, through the test's influence on Lewis Terman (1877–1956) and Lightner Witmer (1867–1956), to shape virtually all subsequent thinking about intelligence testing and its role in society. 相似文献

Recent theories of attention have proposed that selection history is a separate, dissociable source of information that influences attention. The current study sought to investigate the simultaneous involvement of selection history and working-memory on attention during visual search. Experiments 1 and 2 used target feature probability to manipulate selection history and found significant effects of both working-memory and selection history, although working-memory dominated selection history when they cued different locations. Experiment 3 eliminated the contribution of voluntary refreshing of working-memory and replicated the main effects, although selection history became dominant. Using the same methodology, but with reduced probability cue validity, both effects were present in Experiment 4 and did not significantly differ in their contribution to attention. Effects of selection history and working-memory never interacted. These results suggest that selection history and working-memory are separate influences on attention and have little impact on each other. Theoretical implications for models of attention are discussed. 相似文献

Abstract Definitions of and attitudes towards countertransference have changed throughout the twentieth century. From being seen as a contaminant in the analytical process, countertransference has come to be seen by many therapists as a potentially useful source of information about a client and his or her problems. There are dangers as well as benefits associated with analysis and utilization of countertransference. This article reviews these issues and proposes some guidelines that therapists may find useful when contemplating their countertransference reactions to clients, and when considering how best to utilize these. 相似文献

Virtual reality (VR) offers new possibilities for learning, specifically for training individuals to perform physical movements such as physical therapy and exercise. The current article examines two aspects of VR that uniquely contribute to media interactivity: the ability to capture and review physical behavior and the ability to see one's avatar rendered in real time from third person points of view. In two studies, we utilized a state-of-the-art, image-based tele-immersive system, capable of tracking and rendering many degrees of freedom of human motion in real time. In Experiment 1, participants learned better in VR than in a video learning condition according to self-report measures, and the cause of the advantage was seeing one's avatar stereoscopically in the third person. In Experiment 2, we added a virtual mirror in the learning environment to further leverage the ability to see oneself from novel angles in real time. Participants learned better in VR than in video according to objective performance measures. Implications for learning via interactive digital media are discussed. 相似文献

Previous work on human memory has shown that prompting participants with false events and self-relevant information via different types of media such as narratives, edited 2-dimensional images, and mental imagery creates false memories. This study tested a new form of media for studying false memory formation: Immersive Virtual Environment Technology (IVET). Using this tool, we examined how memory was affected by viewing dynamic simulations of avatars performing novel actions. In the study, 55 preschool and elementary children were randomly assigned to 1 of 4 memory prompt conditions (idle, mental imagery, IVET simulation of another child, or IVET simulation of self). Each child was questioned 3 different times: once before the memory prompt, once immediately after the memory prompt, and once approximately 5 days after the memory prompt. Results showed that preschool children were equally likely to develop false memories regardless of memory prompt condition. But, for elementary children, the mental imagery and IVET self conditions caused significantly more false memories than the idle condition. Implications regarding the use of digital media in courtroom settings, clinical therapy settings, entertainment, and other applications are discussed. 相似文献

Theories of visual search have generally assumed that rejected distractors are marked so as to avoid further processing of these items (memory-driven search). To test this assumption, Horowitz and Wolfe (1998) developed the randomized search paradigm, in which standard static search is compared to dynamic search where items are randomly replotted at new locations throughout a trial. Memory-driven search predicts that search slopes should double in the dynamic condition. After reviewing earlier findings that slopes were similar in the two conditions, we present two new experiments. Experiment 1 replicated and extended our previous findings using a larger range of set sizes, a slower rate of change, and adding a fixed location dynamic condition. Experiment 2 employed stimuli that required overt fixation. Neither experiment showed evidence for memory-driven search. We conclude that visual search is best understood as a series of successive judgements of the momentary probability of target presence. 相似文献
