通过对不同双重任务的呈现间隔时间和不同任务难度的双重任务的操作研究,探讨了结构限制与资源竞争对双重任务操作绩效的影响。实验结果表明:(1)两种作业呈现的间隔时间对双重任务操作绩效有明显的影响。间隔时间越大,双重任务的作业绩效越好。(2)作业难度对双重任务的操作有明显的影响。作业难度越大,双重任务的操作绩效越差。(3)两个作业呈现的间隔时间不同并不影响作业难度对双重任务操作绩效的作用。本研究的实验结果进一步证实了双重任务操作的三因素假设:结构限制、信息干扰和资源竞争是影响双重任务操作绩效的三个独立的原因。  相似文献

本文采用“模拟星期”范式通过3个实验分别考察了前瞻记忆任务类型的差异以及动机与任务序列对前瞻记忆的影响。结果表明:(1)规律性前瞻记忆任务的正确率显著高于非规律性的,即使本研究条件下对非规律性前瞻记忆任务进行奖励与惩罚,仍没有消除两者间的差异。(2)不论是惩罚还是奖励都可以显著提高非规律性前瞻记忆的成绩,而且动机促进作用会蔓延至非直接强化的前瞻记忆任务。(3)固定序列前瞻记忆成绩显著优于随机序列的,且在实验过程中固定序列前瞻记忆的成绩呈上升趋势,而随机序列的基本不变,固定序列在一定程度上反映了行为习惯的建立过程。(4)不论前瞻记忆任务规律与否,惩罚或奖励,任务序列如何,基于时间的前瞻记忆成绩均优于基于事件的前瞻记忆的成绩。(5)时间确认任务中,被试翻看时钟的次数与其正确率间呈显著正相关,且越临近规定时间翻看次数越多,呈J型分布。  相似文献

Abstract

American undergraduate students' task liking and intrinsic motivation were examined using 2 × 2 × 2 (Self-Esteem × Task Label × Feedback) analyses of variance. Identical tasks were labeled as either difficult or easy, and bogus performance feedback was given randomly to each subject. For subjects with high self-esteem, feedback had strong impact on their liking of a difficult task, whereas for those with low self-esteem, feedback had strong impact on liking of an easy task. After positive feedback for performing a difficult task, subjects with high self-esteem increased task liking, whereas those with low self-esteem decreased task liking. Subjects also showed higher intrinsic motivation after positive feedback than after negative feedback.  相似文献

This study explores child and parent motivation at the start of a social skills training group program and its relationship with treatment outcome. A total of 59 children (aged 7–12) participated. Parents were more aware of, distressed by, and motivated to change the presenting problem than were their children. Greater parent awareness of their child’s difficulty making and keeping friends and perceived importance of their child learning ways to make and keep more friends significantly predicted more improved social skills. Increasing parents’ awareness and perceived importance of treating the presenting problem at the start of therapy may increase treatment effectiveness.  相似文献

Two experiments examined task engagement, quantified as cardiovascular (CV) response, under conditions of high self-relevance of performance (i. e., when performance had strong implications for the individual's self-definition and self-esteem). Experiment 1 involved a 2 (self-relevance) × 2 (task difficulty) design and revealed, in accordance with predictions derived from Brehm's energization model, that self-relevance per se does not result in high engagement, but that high self-relevance bound up with high task difficulty does. Experiment 2 involved three difficulty conditions (very easy, moderate, very difficult) under highly self-relevant performance conditions and revealed a curvilinear difficulty/engagement relationship. In both studies CV responses were independent of feeling states.  相似文献

Self-focused attention has been found to facilitate task performance in some instances and inhibit it in others. Among chronically anxious individuals it appears to consistently hinder performance. Less is known about the impact of self-focus on the performance of normal individuals. The present study examines the role of task difficulty, task self-relevance, and presence of evaluation anxiety in the performance effects of self-focus among normal individuals. Participants performed a simple reaction time (RT) and a lexical decision task, in Experiments 1 and 2, respectively, with or without self-focus. Self-focus and evaluation anxiety resulted in faster responding in simple RT, but there was no significant effect of self-focus on performance in the more difficult lexical decision task. Participants' heart rate (HR) was monitored and indicated that orienting was associated with slower RT in both experiments, and less orienting was found during self-focus and evaluation conditions. Results are interpreted in light of several self-focus theories.  相似文献

Drawing on Dewey's pragmatic perspective on talent cultivation and previous research on promoting employee creativity in industry, this study investigates student creativity performance in relation to teacher's encouragement, intrinsic motivation, and creative process engagement. Based on survey data collected from 140 vocational high school students who participated in a nation‐wide contest in Taiwan, path analyses were performed using structure equation modeling techniques. The results indicate that both teacher's encouragement and intrinsic motivation have a significant, although indirect, effect on student creativity, and that creative process engagement, as opposed to teacher encouragement or intrinsic motivation, has a direct and significant mediating effect on student creativity. This finding is in partial agreement with prior research which reports student creativity is positively associated with teacher encouragement and intrinsic motivation, highlighting the mediating role of creative process engagement in facilitating student creative performance.  相似文献

以往研究发现个体为自己和为他人的创造表现存在差异,但研究结论不一致。另外,考虑到社会动机是影响“自我-他人”表现的重要因素,本研究采用2(社会动机:亲社会、利己)×2(“自我-他人”:自我、他人)混合实验设计,考察社会动机与“自我-他人”如何来影响创造性表现。结果发现,亲社会组创造性表现的新颖性、有效性和总分均高于利己组,支持了动机性信息加工理论。自我组在创造性表现的新颖性和总分上高于他人组,这与解释水平理论的观点不一致。矛盾的原因可能是在东方“紧”文化背景下,人们按照社会认可的价值体系来为他人创造时,人们对新颖性的态度是谨慎的,因此为自我创造比为他人创造更加新颖。  相似文献

The authors investigated the effects of locus of control expectancies and task difficulty on procrastination. Forty-two college students were administered an academic locus of control scale and a task that was similar to a typical college homework assignment. The students were randomly assigned to 1 of 2 task difficulty levels. Although none of the results involving task difficulty was significant, several results involving locus of control were significant. Specifically, analyses revealed that students with internal locus of control expectancies tended to begin working on the assignment sooner than students with external locus of control expectancies. In addition, students with internal locus of control completed and returned the assignment sooner than students with external locus of control. The results are discussed within the context of J. B. Rotter's (1966, 1975, 1982) social learning theory.  相似文献

This study investigated the effects of self-appraisal information, normative information, and task performance on performance appraisal ratings. Participants rated a fictitious subordinate's performance on a clerical task (which was either very good or moderately poor) subsequent to receiving self-assessment information (high or low) and normative information (present or absent). Self-appraisals affected performance ratings for poor performers but not for good performers, suggesting that judges are more motivated to please ratees than they are merely to adopt the subordinate's view of their own performance. Furthermore, objective normative information had greater influence than self-appraisals on performance ratings, suggesting that information source credibility has more influence than felt accountability on performance appraisals. Implications of the findings for organizations were discussed.  相似文献

Increases in the sophistication of workplace computerization has provided modern-day managers with superior tools, such as electronic performance monitoring (EPM), with which to supervise their employees. Expanding on studies by Aiello (e. g., Aiello, 1993), the present study aimed to examine EPM in a social facilitation framework, exploring not only the relationship with task performance and stress, but also with an individual's subjective mood state. Thirty-three female and 15 male university students were required to solve a series of anagrams via a purpose-built computer program. Both the difficulty of the anagrams (easy or difficult) and the presence of monitoring (present or absent) were varied for each participant. Results indicated that the visual presence of EPM resulted in an easy task being performed with greater proficiency and a difficult task being performed with less proficiency. When participants were attempting to solve an easy task, the presence of EPM resulted in a participant's mood state becoming significantly more positive; whereas when solving a difficult task, EPM caused a more negative mood state. Similarly, it was found that a higher level of subjective stress was experienced when EPM was present, as opposed to absent. when individuals were performing a difficult task. The implications for the workplace applications produced by this study are discussed.  相似文献

This study tested the relation between perceived social impact, social worth, and work engagement in the military, and mediating effects of prosocial motivation. We tested hypotheses using structural equation modeling analysis in a field study with 322 officers and sergeants and 1,045 soldiers of the Portuguese Army. Results confirmed that perceived social impact and social worth were associated with work engagement. Furthermore, regardless of the rank category, perceived social impact was associated with higher prosocial motivation, which in turn was associated with higher work engagement. In the soldiers subsample, results further indicated that soldiers’ perceived social worth was associated with higher prosocial motivation, which in turn was related to higher work engagement. The direct effects of perceived social impact and social worth on work engagement, and the mediating role of prosocial motivation supported the hypothesis that perceptions of social impact and social worth may strengthen the motives to “do good” (prosocial motivation), leading to an upward spiral that cultivates work engagement among members of the military.  相似文献

Role conflict, role ambiguity, and intrinsic task satisfaction are found to moderate the relationship between leader–member exchange (LMX) and subordinate performance. Data from a field study of 146 supervisor–subordinate dyads indicate low conflict, high ambiguity, and high intrinsic satisfaction enhance the link between LMX and performance. Neutralizing effects are found when ambiguity and intrinsic satisfaction are low. High conflict appears to have a constraining effect, whereby the connection between LMX and performance is reduced but not neutralized. Results from the study call attention to the theoretical and practical benefits of examining the LMX/performance link from a contingency perspective, and offer a viable, albeit tentative, explanation for inconsistent findings reported in earlier studies.  相似文献
