The Effects of Identity-Relevance and Task Difficulty on Task Motivation,Stress, and Performance

Tested the hypothesis that the identity-relevance of a performance domain would predict task motivation, stress, and actual performance. Psychology majors and non-majors (N = 94) completed either moderately difficult or very difficulty questions from a standardized verbal aptitude test. Before the test participants were told that performance on the test was either predictive of success as a psychologist (identity-relevant condition) or were given no information on the predictive ability of the test (control condition). Results revealed that only psychology majors evidenced higher motivation and stress in the identity-relevant condition in comparison to the control condition. The results of actual test performance revealed that when identity-relevance was high, psychology majors tended to do better than non-majors on a task of moderate difficulty, but tended to do worse on a task of high difficulty. Implications of the results for identity-relevance as a motivational and emotional lynchpin for performance are discussed. The author would like to thank Cynthia Ellison, Melissa Kinder, and Kelly Riddle for their assistance in data collection. A paper based on the results of the present study was presented at the 2004 meeting of the Southeastern Psychological Association and was the co-recipient of the outstanding professional paper award.     

Contextual Dependencies during Perceptual-motor Skill Performance: Influence of Task Difficulty

The present experiment was designed to address the role of task difficulty for the development of contextual-dependent behaviour during perceptual-motor task acquisition. Task difficulty in the present study was manipulated by restricting the time that the subject; (a) viewed task-relevant information, and (b) was afforded to execute a sequence of key presses. Assuming these manipulations made the acquisition of the key press tasks more difficult, it was hypothesised that reducing the time for either of these processes would result in a greater dependence on reinstating the training context at the time of test. This was based on previous findings reported by Wright and Shea (1991) which indicated that task difficulty can contribute to the development of context-dependent behaviour. The results of the study revealed that viewing time was a potent difficulty manipulation. This is supported by the slower acquisition rates for subjects exposed to short as opposed to long viewing conditions during training. More importantly, the impact of changing the intentional-incidental stimuli relationship that was apparent during training, during the test was greatest for the individuals who experienced shorter viewing times during the training phase. Thus, the proposed influence of task difficulty on contextual-dependent performance was supported. This dependency was manifested as a slowing in both the initiation and execution of the correct key presses. It is proposed that individuals trained in the more difficult viewing condition during training, when faced with an incongruence in the acquisition and test stimuli, must engage additional data-driven verification processes to supplement their extant knowledge in order to execute an appropriate response.     

Presence of Others and Task Performance in Japan and the United States: A Laboratory Investigation

This study examined the effects of culture (Japan and the United States) and task setting (working individually or working in the presence of a group) on job productivity and job quality. Subjects were asked to maximize both their quantity and quality of performance in a laboratory task. Results showed that Japanese subjects had higher productivity than American subjects, but did not have higher quality of work. In addition, both Japanese and American subjects had higher productivity and job quality in the presence of a group than working alone. Against expectations, group presence did not interact with cultural samples.     

Self-Relevance of Performance, Task Difficulty, and Task Engagement Assessed as Cardiovascular Response

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.

The Role of Self-Focus,Task Difficulty,Task Self-Relevance,and Evaluation Anxiety in Reaction Time Performance

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.     

结构限制和作业难度对双重作业绩效的影响

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。     

Joint Relationships of Task Proficiency With Aptitude,Experience, and Task Difficulty: A Cross-Level,Interactional Study

We adopted a cross-level interactional perspective in investigating the prediction of United States Air Force (USAF) jet engine mechanic task-level proficiency from aptitude, experience, and task difficulty. Aptitude, job and task experience, and task difficulty measures all were significant predictors of task proficiency. An hypothesis that task difficulty would moderate the aptitude-task proficiency relationship received no support. Similarly, hypothesized moderating effects of job experience on relationships of task proficiency with aptitude and task difficulty received little support. lhsk-level experience, however, had significant moderating effects on relationships of task proficiency with both aptitude and task difficulty. Aptitude and task difficulty had weaker relationships with task proficiency with increased task experience. We recommend that future research on performance determinants (a) clarify further the experience construct and (b) exploit theoretical and analytic advantages of cross-level and multilevel research designs.

A Longitudinal Investigation of Task and Contextual Performance Influences on Promotability Judgments

Promotions in organizations traditionally have represented the principal measure of career success, and they tend to be based on evaluations or judgments of employees' promotability made by supervisors. Yet theory and research on the antecedents of promotability judgments have presented an inconsistent and ambiguous picture of just what factors are best predictive of such evaluations. In the present investigation, longitudinal data obtained from supervisors of professional employees were used to rigorously test the relative influence of task and contextual performance on judgments of promotability. Results indicate that task and contextual performance not only explain unique variance in judgments of promotability but also interact, such that subordinates who excel in task performance and in the job dedication aspect of contextual performance are judged more suitable for promotion than subordinates who excel in one but not in the other. Implications of results are discussed and future research directions are offered.     

The Influence of Task Difficulty on Context Effect - Compromise and Attraction Effects

Research in psychology finds strong context effects in consumer behavior and help consumer make up their mind from choice set when none of each option better than the others in all aspects. Context effect signifies that when evaluating a focal option, individuals take into consideration characteristics of other comparative alternatives rather than only the features of that focal alternative, complicating the decision-making process. The compromise effect and attraction effect (known together as context effect) explain the underlying motivations that cause consumers to choose the middle option and introduce an inferior option to make the originally dominated option more preferable. But past research on this domain has predominantly used an easy-to-count choice scenario (refers to the ease of using individual’s math skill on comparative attributes in the choice task) which is not ideally existed in real world situation. In real world purchasing situations, most of the time consumers become confused by a variety of products presented with irregular pricing, packaging or attributes which are apparently difficult to compare by math skill. This paper aim to examine “When the level of difficulty changed while processing the comparative task on the context of a choice set, how does this influence the resultant occurrence of context effect?” Results from four experiments demonstrate that both compromise and attraction effects decreased when the choice task become more difficult.     

Goal Difficulty and Creative Performance: The Mediating Role of Stress Appraisal

We investigated whether the effect of goal difficulty on creativity may be clarified by examining how people appraise their working conditions. In an experiment, 157 undergraduate students completed a divergent thinking task for which goal difficulty was manipulated. Stress appraisals were assessed through self-reports, and creativity was evaluated by independent judges. Results indicated that difficult goals, although categorized as a challenge stressor, can also be appraised as a hindrance and/or a threat. Although there was a direct positive effect of difficult goals on creative performance, hindrance appraisals partially mediated a negative relationship between goal difficulty and creative performance. Results highlight that stress appraisals can help clarify inconsistent effects of stressors, with implications for managing creativity.     

The Effect of Retention Interval Task Difficulty on Young Children's Prospective Memory: Testing the Intention Monitoring Hypothesis

The current study examined the impact of retention interval task difficulty on 4- and 5-year-olds’ prospective memory (PM) to test the hypothesis that children periodically monitor their intentions during the retention interval and that disrupting this monitoring may result in poorer PM performance. In addition, relations among PM, working memory, theory of mind (ToM), and 2 types of planning were investigated. Children (N = 64) were randomly assigned to an easy or difficult filler task during the retention interval prior to the PM task. Five-year-olds outperformed 4-year-olds on the PM task, and children receiving the easy filler task outperformed those receiving the difficult filler task. Further, working memory, planning, and ToM were positively associated with PM for children receiving the difficult filler task but not for children receiving the easy filler task. Findings are interpreted with respect to the predictions of the intention monitoring hypothesis as well as the multiprocess framework of PM.     

任务难度和反馈学习对儿童类比推理能力的影响

该研究采用情景类比任务,通过两个实验对180名小学生进行纸笔测验,探讨了任务难度对儿童类比推理能力的影响.结果发现:进行反馈学习以降低任务难度时,7～8岁儿童能完成更高年龄段儿童才能完成的任务;但增加任务难度,11岁以上儿童也表现出类比推理能力的弱化.结果提示,儿童是否能在类比推理任务中表现出相应的能力可能取决于任务难度,反馈学习可促进一定年龄段内儿童的类比推理能力发展.本结果为有机融合皮亚杰和Goswami等人的观点提供了有效的实验依据.     

A Meta-Analytic Investigation of the Relationship Between State Affect,Discrete Emotions,and Job Performance

The relationship between affect and job performance has been the topic of previous meta-analytic investigations. However, these studies have been limited by their focus on only one form of affect, trait dimensional affect, or failure to differentiate between various forms of affect, such as state affect and emotions. The present study extends past research by meta-analytically examining the association between state dimensional affect and discrete emotions and three dimensions of job performance, task performance, organizational citizenship behavior, and counterproductive work behavior. In addition, we examined subgroup differences according to the temporal consistency of performance and affect measurement, and we reviewed studies that assessed the affect–performance link using within-person analyses in the context of experience sampling designs.     

The Influence of Affect on Goal Choice and Task Performance

The present study investigated the influence of mood on self-set goals and task performance. Results from 2 studies suggest a restricted view of mood effects in which affective state influences the level of self-set goals or task performance, but not both. Study 2 reveals asymmetrical mood effects on task performance, with positive- and negative-mood participants exceeding the baseline performance of neutral mood participants. Evidence indicates that goal-setting instructions may alter how individuals interpret motivational implications of mood. Although theory implies an inclusive view in which mood has both direct and indirect (through goal-setting) performance effects, the conflicting influences of affect infusion at different points of the goal-striving process may diminish the likelihood of observing inclusive effects.     

The Influence of Goal Orientation on Task Performance: A Substantively Meaningful Suppressor Variable1

The present study investigated the relationship between performance goal orientation and performance on a complex task. It was hypothesized that cognitive interference would mediate this relationship. In addition, it was hypothesized that cognitive ability would moderate the relationship between cognitive interference and task performance. A three-variable suppressor relationship indicated that, although the direct effect of performance goal orientation on performance was one that produced better performance, the indirect effect of performance goal orientation indicated that performance orientations were associated with increases in cognitive interference, and these increases in cognitive interference were associated with poorer performance. Thus, the beneficial aspect of performance goal orientation (i. e., the direct effect) was counterbalanced by the dysfunctional aspects of performance goal orientation (i. e., the associated increase in cognitive interference). Support was also found for the proposed moderation of ability on the cognitive interference-task performance relationship for final, but not initial performance. The results are interpreted in light of recent discussions regarding the influence of goal orientation on task performance and cognitive interference.     

Examining Situationally Induced State Goal Orientation Effects on Task Perceptions,Performance, and Satisfaction: A Two‐Dimensional Conceptualization1

We examined the longitudinal effects of situationally induced 2‐dimensional state goal orientations (i.e., achievement goals) on perceptions, performance, and satisfaction. Results (N = 268) indicated that high state learning cues led to higher perceived challenge and, for higher ability individuals, greater performance gains. Further, high state performance cues led to higher perceived effort. However, results revealed that state learning and performance effects were more complex than expected. State learning effects on challenge and state performance effects on effort were both stronger with other cues absent. Additionally, increasingly beneficial state learning cue effects were stronger for higher ability individuals. Thus, results provided support that state learning and performance goals are separate dimensions, and their interactive effects need further examination.     

Effects of State Humor,Expectancies, and Choice on Postsurgical Mood and Self-Medication: A Field Experiment1

It was hypothesized that repeated exposure to humorous material reduces distress, pain, and medication following surgery. This hypothesis was tested in a field experiment by randomly assigning 78 postsurgical patients to either a control group or 1 of 8 experimental groups formed by the factorial crossing of type of videotape (humorous vs. serious), perceived control (choice vs. no choice), and expectation (positive vs. none). Multivariate analyses of variance disclosed that humor reduced requests for minor medication, combined with expectations to reduce pain, but increased use of heavy analgesic when patients were deprived of choice. Although more research needs to be done, the findings suggest that hospital patients benefit from humorous and distracting material when exposure is voluntary.     

Performance Monitoring as a Moderator of the Relations Between Two Conscientiousness Measures and Task Performance

The present study investigated the moderating effects of performance monitoring on the relations between two measures of conscientiousness (general and business-oriented) and performance on a data entry task. A significant interaction was evidenced between conscientiousness and performance monitoring in predicting task performance for the general measure of conscientiousness; however, it was opposite than expected. No significant interaction was evidenced between conscientiousness and performance monitoring in predicting task performance for the business-oriented measure of conscientiousness. Possible explanations for these findings are suggested. Implications and limitations of the present research are identified and various suggestions for future research in this area are recommended.
