This study examined the incidence of attention lapses and microsleeps under contrasting levels of task complexity during three tasks: PVT, 2-D tracking and a dual task combining the two. More attention lapses per participant (median 15 vs. 3; range 1–74 vs. 0–76, p = 0.001), with the greatest increase with time spent-on-task (p = 0.002), were evident on the more cognitively-demanding dual task than on the PVT. Conversely, fewer microsleeps (median 0 vs. 0; range 0–1 vs. 0–18, p = 0.022) occurred during the more complex task compared to the tracking task. An increase in microsleep rate with time spent-on-task (p = 0.035) was evident during the tracking task but not the dual task. These results indicate that the higher cognitive load, associated with an increase in task complexity, increased the likelihood of attention lapses, while a reduction in task complexity increased the likelihood of microsleeps. 相似文献

The platinum mining sector in South Africa presents a significant context for the study of work engagement, given the major changes and turmoil experienced by employees in this sector. The aim of this study was to investigate the effects of task and relational factors on work engagement in the platinum mining industry in South Africa. A stratified random sample (N = 564) comprising employees in a platinum mining organisation in South Africa was surveyed (females = 35.1%, blacks = 51.6%, middle managers = 40.8%). The employees completed a biographical questionnaire and several other measures: the Engagement Scale, Supervisory Support Scale, Social Support Scale and Job Diagnostic Survey. The results supported a reliable three-factor structure (consisting of autonomy support, competence support, and relatedness support) for the Supervisory Support Scale. The structural model confirmed that task characteristics (comprising task significance and task identity) were strongly related to work engagement. Supervisor support and co-worker support showed a positive relationship with work engagement, albeit to a lesser extent. 相似文献

PurposeA limited number of studies have looked at the negative effect that cognitive fatigue has on physical performance.Methods and resultsTwo studies were conducted to assess the impact of a cognitive task on performance in an externally paced running task. In study 1, 12 trained athletes completed a standardized shuttle run, once after a cognitively fatiguing task (unmatched stroop for 10 min) and once after an easy cognitive task (matched stroop for 10 min). Performance in the shuttle run test did not differ between the two conditions, and, surprisingly, perceived effort was significantly higher in the control condition. In study 2, the control condition was modified and the easy cognitive task replaced by watching a video. 11 trained athletes completed both sessions, however, there were again no differences in either performance or in perceived effort.ConclusionBoth studies failed to reveal an impact of cognitive fatigue on subsequent physical performance. These findings contribute to the growing body of literature in this area, showing that the relationship between cognitive and physical task completion is not straightforward, and that other important factors still remain for investigation. 相似文献

Previous research shows that European Americans are consistently more independent (or less interdependent) than Japanese when implicit indices are used to assess independence (vs. interdependence). The present work extended this evidence by including a novel implicit association test (IAT), as an index of implicit attitude towards independence and interdependence. Consistent with the previous findings, as compared to Japanese, Americans were significantly higher in multiple indices of implicit independence (vs. interdependence) including personal (vs. social) self‐definition, experience of disengaging (vs. engaging) emotions and personal (vs. social) form of happiness. Furthermore, as compared to Japanese, Americans had a significantly more positive implicit attitude towards independence assessed with the IAT. As also observed in the previous research, explicit measures showed inconsistent cross‐cultural patterns. Lastly, we observed little statistical within‐culture coherence among the implicit measures of independence (vs. interdependence), consistent with a view that the implicit indices capture alternative ways for individuals to achieve the cultural mandate of independence or interdependence. 相似文献

Longevity of attentional bias modification effects for food cues in overweight and obese individuals
Accumulating evidence shows that overweight individuals exhibit an attentional bias for food and that this bias can be modified. This study investigated the longevity of such modification effects. Using a dot probe paradigm, a community sample of overweight and obese women (N = 104) was trained to direct attention towards (‘attend’) or away from (‘avoid’) food pictures. Participants completed five weekly training sessions. Attentional bias was measured before and after training, at 24 h and one-week follow-up. To increase generalisability, at each of the post-training and follow-up assessments, participants were shown a mix of old and new food pictures. They also completed another implicit bias measure, i.e. a word stem task. Attentional bias for food increased in the ‘attend’ group and decreased in the ‘avoid’ group. These retraining effects were maintained at 24 h and one-week follow-up, and extended to new food pictures. Participants in the ‘avoid’ group also produced relatively fewer food words on the word stem task than those in the ‘attend’ group. Results are consistent with predictions of cognitive-motivational models that attentional biases are malleable. They further suggest that attentional bias modification, which targets the implicit processes that underlie the heightened food responsivity in overweight individuals, could help combat pathological (over)eating. 相似文献

Individuals with adaptive expertise possess the skills to deal with novel problems. Whereas this concept has been around since the mid-1980s, no instrument exists that provides a good operationalization of the theoretical construct. This inhibits the further development of research on adaptive expertise and the evaluation of employees’ adaptive expertise levels. Adaptive expertise has been unanimously described as a composition of domain-specific and innovative skills. Some researchers argue that metacognitive skills are also crucial. This study aimed to establish whether an instrument measuring adaptive expertise is composed of these three dimensions. In addition, it was tested whether such an instrument is influenced by task variety and work experience, as previously reported in literature. A sample of 383 professionals and graduates were used to test the Adaptive Expertise Inventory. Through exploratory factor analysis (EFA), (E/CFA), and confirmatory factor analysis (CFA), the quality of the instrument was evaluated. Good model fit was achieved. The final instrument consisted of two dimensions—i.e., domain-specific and innovative skills—with five items each. Regression analysis showed that not work experience, but task variety is related to level of adaptive expertise. The Adaptive Expertise Inventory proved to be a valid instrument for measuring adaptive expertise. 相似文献

Grounded in expectancy value theory (EVT), a moderated mediation model predicting children’s physical activity (PA) enjoyment was tested. Ability beliefs and subjective task value were initially investigated as mediating the relationship between social support from friends and PA enjoyment. It was hypothesized that children play an active role in this socialization process with support seeking self-efficacy moderating the mediated relationships. Findings revealed PA social support from friends and PA enjoyment was mediated by PA ability beliefs, but this mediated relationship was conditional on children having average-to-high levels of support seeking self-efficacy. The mediated relationship between PA social support from friends and PA enjoyment through subjective task value was not moderated by support seeking self-efficacy. Results support the importance of instilling confidence in children to seek out PA support in order to maximize opportunities for PA enjoyment and suggest pathways may be more complex than originally posited in EVT. 相似文献

A commonly held view in both exogenous and endogenous orienting is that spatial attention is associated with enhanced processing of all stimuli at the attended location. However, we often search for a specific target at a particular location, so an observer should be able to jointly specify the target identity and expected location. Whether attention can bias dimension-specific processes at a particular location is not yet clear. We used a dual task to examine the effects of endogenous spatial cues on the accuracy of perceptual judgments of different dimensions. Participants responded to a motion target and a colour target, presented at the same or different locations. We manipulated a central cue to predict the location of the motion or colour target. While overall performance in the two tasks was comparable, cueing effects were larger for the target whose location was predicted by the cue, implying that when attending a particular location, processing of the likely dimension was preferentially enhanced. Additionally, an asymmetry between the motion and colour tasks was seen; motion was modulated by attention, and colour was not. We conclude that attention has some ability to select a dimension at a particular location, indicating integration of spatial and feature-based attention. 相似文献

While anxiety is typically thought to increase distractibility, this notion mostly derives from studies using emotionally loaded distractors presented in the same modality as the target stimuli and tasks involving crosstalk interference. We examined whether pathological anxiety might also increase distractibility for emotionally neutral irrelevant sounds presented prior to target stimuli in a task where these stimuli do not compete for selection. Patients with anxiety and control participants categorized visual digits preceded by task-irrelevant sounds that changed on rare trials (auditory deviance). Both groups exhibited an equivalent increase in response times following a deviant sound but patients showed a reduction of response accuracy, which was entirely due to an increase in response omissions. We conclude that the involuntary capture of attention by unexpected stimuli may, in patients with anxiety, result in a temporary suspension of cognitive activity. 相似文献
