Three experiments indexed the effect of various concurrent tasks, while watching a traumatic film, on intrusive memory development. Hypotheses were based on the dual-representation theory of posttraumatic stress disorder (C. R. Brewin, T. Dalgleish, & S. Joseph, 1996). Nonclinical participants viewed a trauma film under various encoding conditions and recorded any spontaneous intrusive memories of the film over the following week in a diary. Changes in state dissociation, heart rate, and mood were also measured. As predicted, performing a visuospatial pattern tapping task at encoding significantly reduced the frequency of later intrusions, whereas a verbal distraction task increased them. Intrusive memories were largely unrelated to recall and recognition measures. Increases in dissociation and decreases in heart rate during the film were also associated with later intrusions. 相似文献

The present study did not replicate Holmes,' et al.'s (1987) findings that medical students who participated in a summer psychiatric research clerkship scored statistically significantly higher than matched controls on the Behavioral Science portion of the National Board of Medical Examiners' Part I Exam. Group ns in this replication were 39 each. 相似文献

The movement-related cortical potential (MRCP) is a low-frequency negative shift in the electroencephalographic recording that occurs about 2 s before voluntary movement production. The MRCP is thought to reflect the cortical processes involved in movement planning and movement preparation. In recent years, researchers have used this potential to investigate the processes involved in motor skill learning. Their findings indicate differences in the amplitude and onset times of the MRCP between experienced and novice performers, which have been attributed to long-term training in the experts. The authors discuss these findings critically and consider their implications for both future research and practice. 相似文献

A consequential ideology in Western society is the uncontested belief that a committed relationship is the most important adult relationship and that almost all people want to marry or seriously couple (DePaulo & Morris, 2005). In the present article, we investigated the extent to which the system justification motive may contribute to the adoption of this ideology. In Studies 1 and 2, we examined whether a heightened motive to maintain the status quo would increase defense of committed relationship values. In Study 3, we examined the reverse association, that is, whether a threat to committed relationship ideology would also affect sociopolitical system endorsement. As past research has found that the justification of political systems depends upon how much these systems are perceived as controlling, in Study 4 we tested whether the defense of the system of committed relationships would also increase when framed as controlling. Results from Studies 1-4 were consistent with our hypotheses, but only for men. In Study 5, using cross-cultural data, we sought to replicate these findings correlationally and probe for a cause of the gender effect. Results from more than 33,000 respondents indicated a relationship (for men) between defense of the sociopolitical system and defense of marriage in countries where the traditional advantages of men over women were most threatened. In Studies 6 and 7, we investigated when this gender difference disappears. Results revealed that when we measured (Study 6) or manipulated (Study 7) personal relationship identity rather than relationship ideology, effects also emerge for women. 相似文献

This paper explores the correlates of career satisfaction among Canadian managers, professionals and executives, specifically the career satisfaction experience of both visible minority and non-visible minority immigrants. Survey data collected from over 13,000 managers, professionals and executives in 43 Canadian organizations were analysed using the ordinary least squares multiple regression technique. Results indicate that immigrants experience lower career satisfaction than native-borns and visible minority immigrants have lower career satisfaction than non-visible minority immigrants. Employee and employer characteristics, objective employment outcomes and subjective perceptual measures were found to be positively associated with career satisfaction for immigrant and native-born respondents. 相似文献

Adaptive computerized training has been associated with significant enhancements in untrained working memory tasks, but the nature of the cognitive changes that underpin these improvements are not yet fully understood. Here, we investigate the possibility that training stimulates the use of memory-related strategies. In a randomized controlled trial, participants completed four tests of working memory before receiving adaptive working memory training, nonadaptive working memory training with low memory loads, or no training. Open-ended interviews about strategy use were conducted after the administration of untrained working memory tasks at two time points. Those in the adaptive and nonadaptive groups completed the assessments before (T1) and after (T2) 10 training sessions. The no-training group completed the same set of tasks at T1 and T2, without any training between assessment points. Adaptive training was associated with selective improvements in untrained tests of working memory, accompanied by a significant increase in the use of a grouping strategy for visuospatial short-term memory and verbal working memory tasks. These results indicate that training-related improvements in working memory may be mediated by implicit and spontaneous changes in the use of strategies to subsegment sequences of information into groups for recall when the tasks used at test overlap with those used during training. 相似文献

ABSTRACTThe authors answer recent responses by Steensma & Cohen-Kettenis (2018) and Zucker (2018) to our critical commentary on “desistance” stereotypes and their underlying research on trans and gender diverse children (Temple Newhook et al., 2018). We provide clarification in the following areas: (1) the scope of our paper; (2) our support of longitudinal studies; (3) consequences of harm to trans and gender diverse children; (4) clinical practice implications; (5) concerns about validity of research methodology; and (6) the importance of learning to listen to trans and gender diverse children. 相似文献
