The visible movement of a talker's face is an influential component of speech perception. However, the ability of this influence to function when large areas of the face (~50%) are covered by simple substantial occlusions, and so are not visible to the observer, has yet to be fully determined. In Experiment 1, both visual speech identification and the influence of visual speech on identifying congruent and incongruent auditory speech were investigated using displays of a whole (unoccluded) talking face and of the same face occluded vertically so that the entire left or right hemiface was covered. Both the identification of visual speech and its influence on auditory speech perception were identical across all three face displays. Experiment 2 replicated and extended these results, showing that visual and audiovisual speech perception also functioned well with other simple substantial occlusions (horizontal and diagonal). Indeed, displays in which entire upper facial areas were occluded produced performance levels equal to those obtained with unoccluded displays. Occluding entire lower facial areas elicited some impairments in performance, but visual speech perception and visual speech influences on auditory speech perception were still apparent. Finally, implications of these findings for understanding the processes supporting visual and audiovisual speech perception are discussed. 相似文献

The current research examines the link between narcissism and creativity at the individual, relational, and group levels of analysis. It finds that narcissists are not necessarily more creative than others, but they think they are, and they are adept at persuading others to agree with them. In the first study, narcissism was positively associated with self-rated creativity, despite the fact that blind coders saw no difference between the creative products offered by those low and high on narcissism. In a second study, more narcissistic individuals asked to pitch creative ideas to a target person were judged by the targets as being more creative than were less narcissistic individuals, in part because narcissists were more enthusiastic. Finally, a study of group creativity finds evidence of a curvilinear effect: Having more narcissists is better for generating creative outcomes (but having too many provides diminishing returns). 相似文献

Stanford-Binet and Wechsler Adult Intelligence Scale (WAIS) IQs were compared for a group of 74 adults with intellectual disability (ID). In every case, WAIS Full Scale IQ was higher than the Stanford-Binet Composite IQ, with a mean difference of 16.7 points. These differences did not appear to be due to the lower minimum possible score for the Stanford-Binet. Additional comparisons with other measures suggested that the WAIS might systematically underestimate severity of intellectual impairment. Implications of these findings are discussed regarding determination of disability status, estimating prevalence of ID, assessing dementia and aging-related cognitive declines, and diagnosis of ID in forensic cases involving a possible death penalty. 相似文献

This article focuses on an exercise to facilitate students' self‐evaluation at the end of a course year. It describes an externalizing technique using objects as metaphors . Although developed in the context of a foundation level course, it is equally relevant for evaluating learning at any stage. 相似文献

Teams that have positive beliefs about their capability tend to perform more effectively. However, relatively little is known about the nature and change of different types of team capability beliefs. Team potency and team efficacy are two approaches to understanding team capability beliefs, but few studies have considered these beliefs simultaneously. We investigate their distinctiveness and relative predictive power. Additionally, we propose two types of team efficacy: team outcome efficacy and team process efficacy. In two longitudinal samples of executive MBA study teams (sample 1, N=213 individuals in 41 teams; sample 2, N=360 individuals in 89 teams), we showed that team potency, team outcome efficacy, and team process efficacy are factorially distinct and measure invariant at four time points over 7 months (except for high levels of team outcome efficacy for which factorial invariance emerged). We also show differential predictive validity. Team outcome efficacy was the strongest predictor of objective team performance, whereas team process efficacy was the best predictor of citizenship behaviours. Team potency predicted both outcomes, albeit more weakly. Collectively, the findings show the value of a more fine‐grained approach to teams' capability beliefs, including a new validated measure of team process efficacy. 相似文献

Data management raises a number of issues, both regulatory and non-regulatory. Researchers should understand how data are
defined by their particular institutions and regulatory authorities. Data are the bases of scientific communication and provide
a strong defense against allegations of scientific misconduct. Authorization is often necessary before collection of data
can commence. Proper handling, retention, and storage of data, especially that involving humans, are crucial for the researcher.
Data ownership by the institution leads to a responsibility by the institution to educate all its researchers in responsible
data management practices. 相似文献

In two experiments, we studied the temporal dynamics of feature integration with auditory (Experiment 1) and audiovisual (Experiment 2) stimuli and manual responses. Consistent with previous observations, performance was better when the second of two consecutive stimuli shared all or none of the features of the first, rather than when only one of the features overlapped. Comparable partial-overlap costs were obtained for combinations of stimulus features and responses. These effects decreased systematically with increasing time between the two stimulus-and-response events, and the decreased rate was comparable for unimodal and multimodal bindings. General effect size reflected the degree of task relevance of the dimension or modality of the respective feature, but the effects of relevance and of temporal delay did not interact. This suggests that the processing of stimuli on task-relevant sensory modalities and feature dimensions is facilitated by task-specific attentional sets, whereas the temporal dynamics might reflect that bindings “decay” or become more difficult to access over time. 相似文献

Previous research has shown that suspects in real-life interviews do not display stereotypical signs of nervous behaviours, even though they may be experiencing high detection anxiety. We hypothesised that these suspects may have experienced cognitive load when lying and that this cognitive load reduced their tonic arousal, which suppressed signs of nervousness. We conducted two experiments to test this hypothesis. Tonic electrodermal arousal and blink rate were examined during task-induced (Experiment 1) and deception-induced cognitive load (Experiment 2). Both increased cognitive difficulty and deception resulted in decreased tonic arousal and blinking. This demonstrated for the first time that when lying results in heightened levels of cognitive load, signs of nervousness are decreased. We discuss implications for detecting deception and more wide-ranging phenomena related to emotional behaviour. 相似文献

Although work-related driving is associated with high accident rates, limited research has investigated the factors influencing driving crashes in the work setting. This study explored multilevel influences on self-reported crashes in the workplace by surveying a sample of work-related drivers (n = 380), their workgroup supervisors (n = 88), and fleet managers (n = 47). At the driver level of analysis, safety motivation predicted self-reported crashes. In turn, drivers' perceptions of their fleet managers' safety values (but not drivers' perceptions of their supervisors' safety values), their own attitudes, and their own efficacy beliefs predicted motivation to drive safely. Furthermore, the influence of supervisors and fleet managers interacted such that drivers were more motivated to drive safely if they perceived both their supervisor and fleet manager to value safety. This study also explored the cross-level relationships between supervisors' and fleet managers' perceptions of organizational safety values and drivers' perceptions of managerial safety values and found a relationship between fleet managers' perceptions of organizational safety values and drivers' perceptions of fleet managers' safety values. These results illustrate that perceptions of workplace safety values are transmitted across levels of the organization. 相似文献
