The authors review studies of mentally simulated movements. In automatic or cyclical movements, actual and motor imagery (MI) durations are similar. When athletes simulate only dynamic phases of movement or perform MI just before competing, however, environmental and time constraints lead to an underestimation of actual duration. Conversely, complex attention-demanding movements take longer to image. Finally, participants can modify the speed of MI voluntarily when they receive specific instructions. To complete the available data, the authors compared imagined and actual durations in tennis and gymnastics. Results showed systematic and disproportionate overestimation of actual duration. The authors found a relationship between complex motor skills and MI duration. They discuss the factors leading to over- and underestimation and the hypotheses that could be tested. 相似文献

The authors examined differences between young adults (n = 25) and healthy older adults (n = 48) in reaction time and the relations between center of pressure (COP) and center of mass (COM) motions during rapid initiation and termination of voluntary postural sway. Older adults were divided into low and high falls-risk groups based on Physiological Profile Assessment scores of sensorimotor function. Low falls-risk older adults had slower reaction times during anteroposterior sway initiation and decreased COP–COM separation during anteroposterior and medialateral sway initiation and anteroposterior continuous voluntary sway compared with young adults. High falls-risk older adults had slower initiation and termination reaction times in all response directions and decreased COP–COM separation during sway initiation and continuous voluntary sway in the anteroposterior and medialateral directions compared with young adults. Compared with low falls-risk older adults, high falls-risk older adults had slower initiation and termination reaction times in all response directions and decreased COP–COM separation during medialateral continuous voluntary sway. Reaction time and COP–COM measures significantly predicted group status in discriminant models with sensitivities and specificities of 72–100%. Overall, these findings highlight important associations of age-related declines in sensorimotor function related to an increased risk of falling with slower postural reaction time and reduced postural stability. 相似文献

This study investigated how individual differences in anxiety modulate the neural response to errors and performance feedback. The design included false feedback on some trials in order to test the hypothesis that anxious people show stronger neural reactions to feedback that is worse than expected. Participants completed a trial-and-error learning task that required learning the correct key to press in response to face images. EEG was recorded during the task, and the response-locked error-related negativity (ERN) and feedback-locked ERN were computed to measure neural responses to error commission and feedback. As expected, errors produced a response-locked ERN and false feedback produced a feedback-locked ERN in the group as a whole. High levels of trait worry predicted a disproportionately larger ERN following false feedback, but did not predict the magnitude of the response-locked ERN following errors. These results imply that worry-prone people react more strongly to violations of expectations, rather than to errors themselves. 相似文献

Emotions are central to the experience of literary narrative fiction. Affect and mood can influence what book people choose, based partly on whether their goal is to change or maintain their current emotional state. Once having chosen a book, the narrative itself acts to evoke and transform emotions, both directly through the events and characters depicted and through the cueing of emotionally valenced memories. Once evoked by the story, these emotions can in turn influence a person's experience of the narrative. Lastly, emotions experienced during reading may have consequences after closing the covers of a book. This article reviews the current state of empirical research for each of these stages, providing a snapshot of what is known about the interaction between emotions and literary narrative fiction. With this, we can begin to sketch the outlines of what remains to be discovered. 相似文献

The aim of this study was threefold: (a) to assess the factor structure of the Kessler Psychological Distress Scale (K10) to determine whether interpreting the scale as a single dimensional measure of psychological distress is justified in military operational setting; (b) to validate the K10 for mental health surveillance in operational settings against self-reported occupational impairment; (c) to evaluate whether the K10 has better discriminatory power than de facto standards for mental health surveillance on deployment, namely the Patient Health Questionnaire and the Posttraumatic Stress Disorder Checklist, Civilian version. A convenience sample of Canadian Armed Forces personnel serving in Afghanistan (N = 1,264) completed self-report measures of psychological distress and occupational impairment. On examination of 6 competing models, the authors determined that interpreting the K10 as a measure of unspecified psychological distress is justified. Using receiver operating characteristic (ROC) curve analysis, they identified new cutoff values for dichotomous and polychotomous scoring methods. After comparing the area beneath the ROC curves for each of the 3 mental health surveillance questionnaires, the authors determined that all measures perform well as predictors of self-rated occupational impairment, with values ranging from .86 to .90. These results highlight the importance of cross-setting validation and demonstrate that validating psychological screening questionnaires against self-report measures of occupational impairment can be a useful strategy for understanding the manifestation of psychological distress on deployed military operations. 相似文献

Organizations today place great emphasis on the selection of their managerial and supervisory personnel. Consequently, the need to develop strong predictors of leadership for use in selection tests is immense. Theoretically and historically, intelligence, dominance, masculinity-femininity, and self-monitoring have been strong indicators of leadership. Accordingly, biographical questionnaires and personality inventories were administered to 1137 Air Force officers attending Squadron Officer School to determine their levels of intelligence, dominance, femininity, masculinity, and self-monitoring. These traits and individual difference variables were then used in a discriminant analysis to predict the subject's classification into one of four leadership categories. Analyses showed differences between leaders and nonleaders for intelligence, dominance, and femininity, but not for self-monitoring. However, a discriminant analysis and associated cross-validation resulted in no predictive capability. A possible reason for the lack of classification capability was the uniqueness of the military sample. Since military individuals seem to share very common experiences and beliefs, the sample appeared to be quite homogeneous, making differences between leaders and nonleaders extremely difficult to detect. Future studies should address this potential problem. 相似文献
