We tested the ability of the mature visual system for discrimination between types of elliptic biological motion on the basis of event kinematics. Healthy adult volunteers were presented with point-light displays depicting elliptic motion when only a single dot, a moving point-light arm, or a whole point-light human figure was visible. The displays were created in accordance with the two-thirds power kinematic law (natural motion), whereas the control displays violated this principle (unnatural motion). On each trial, participants judged whether the display represented natural or unnatural motion. The findings indicate that adults are highly sensitive to violation of the two-thirds power kinematic law. Notably, participants can easily discriminate between natural and unnatural motions without recognising the stimuli, which suggests that people implicitly use kinematic information. Most intriguing, event recognition seems to diminish the capacity to judge whether event kinematics is unnatural. We discuss possible ways for a cross-talk between perception and production of biological movement, and the brain mechanisms involved in biological motion processing. 相似文献

Many project groups have a hard time meeting their deadlines. This research addresses this issue by studying group perceptions and group self-regulatory actions that may impede or foster the timeliness of group projects. Longitudinal data were collected from 22 student project groups developing a business solution in a field assignment. Using a questionnaire, we measured perceived time pressure, group potency, planning, and reflexivity, as well as the project's progress at three points during the 13-week working period: at the start of the project, just after the orientation phase, and finally after the execution phase and the project deadline. Our findings suggest that the effect of time pressure on progress is moderated by group potency. Furthermore, there were differential effects of planning and reflexivity in the orientation phase and the execution phase. Execution planning and reflexivity did not appear to be very useful for progress in the orientation phase of the project. However, in the execution phase, both planning and reflexivity contributed to meeting the deadline. 相似文献

In a cross-sectional field study we found, as predicted, that performance differences between members of semi-autonomous teams were associated with feelings of unfairness. On the basis of equity theory we hypothesized that the relationship between performance differences and unfairness feelings would be moderated for suckers, i.e., team members with relatively high performances, who feel highly rewarded for their efforts, either with high financial rewards, with high task rewards, or with high social rewards. The results showed that financial rewards had no moderating effects, but high social rewards and low task rewards moderated feelings of unfairness for suckers. 相似文献

A reduction in the incidence of cardiovascular diseases (CVD) has been reported in the Western world, but post‐infarction depression often occurs and is related to poor medical outcomes. The aim of this study was to examine the scientific literature by a systematic review, in order to find evidence for whether physical activity can be a tool to reduce depression in patients who have suffered a cardiac event. Three databases were systematically searched (PubMed, CINAHL, and Cochrane), and the GRADE protocol was used in combination with a revised Amstar‐protocol for the systematic review. Scientific reports fitting the area were scarce. Finally, ten studies were included in this study: one meta‐analysis, five randomized controlled trials, and four clinical trials. The results showed low to moderate evidence for the use of low to moderate levels of exercise as a tool to reduce depression in post‐coronary artery event patients. This study concluded positive effects of physical activity as a tool to reduce depression in post‐coronary artery event patients. Physiotherapists could be further involved in increasing physical activity after cardiac events. More studies are needed in the area. 相似文献

This paper presents a review of studies that were aimed at determining which brain regions are recruited during visual self-recognition, with a particular focus on self-face recognition. A complex bilateral network, involving frontal, parietal and occipital areas, appears to be associated with self-face recognition, with a particularly high implication of the right hemisphere. Results indicate that it remains difficult to determine which specific cognitive operation is reflected by each recruited brain area, in part due to the variability of used control stimuli and experimental tasks. A synthesis of the interpretations provided by previous studies is presented. The relevance of using self-recognition as an indicator of self-awareness is discussed. We argue that a major aim of future research in the field should be to identify more clearly the cognitive operations induced by the perception of the self-face, and search for dissociations between neural correlates and cognitive components. 相似文献

Purpose
The purpose of this study was to test a model that proposes that innovative cognitive style and self-regulation (setting priorities, planning work activities, and monitoring time and task progress) are related to the self-reported success of architects. We investigated two aspects of the success: as designers and as business people. To this end, we examined the mediating role of self-efficacy in these relationships. 相似文献47.
