Locus of control predicts appraisals and cardiovascular reactivity to a novel active coping task

These two studies investigated the influence of dispositional locus of control (LOC) on subjective and physiological responses to a novel laboratory stressor task. Across two studies, 64 healthy undergraduate students, ages 18-22, completed Levenson's (LOC) scales for internal, powerful others, and chance prior to performing a video-game task. Participants rated pretask and posttask stressfulness and coping ability (i.e., measures of primary and secondary appraisal). Cardiovascular measures (heart period, HP; preejection period, PEP; respiratory sinus arrhythmia, RSA; cardiac output, CO; systolic blood pressure, SBP; diastolic blood pressure, DBP & total peripheral resistance, TPR) were recorded during 4-minute baseline and 4-minute stressor task periods. The internal LOC factor predicted pretask reports of coping ability as well as posttask reports of stressfulness. In contrast, the powerful-others LOC factor predicted cardiac changes (HP, PEP, and RSA) during the task but not cardiac output or any other vascular change measure. These results underscore the importance of using the three subscales of the Levenson LOC to assess relationships between dispositional LOC and the response to stressors because self-reported appraisals of a task are predicted by a different component of dispositional LOC than are task-related cardiovascular functions.     

Relations between general goal orientations and task-specific self-appraisals

Abstract:   The purpose of the present study was to examine the influence of goal orientations on ninth-grade students' (54 girls and 55 boys) task-specific appraisals (i.e., anticipated interest, self-efficacy, test anxiety, and physical symptoms) and subsequent task performance. The results of structural equation modeling showed that different goal orientations had different effects on task-specific appraisals. In addition, task performance was directly influenced by self-efficacy and physical symptoms, whereas the goal orientation served as a predictor of task performance indirectly through task-specific appraisals. Students' posttask estimation of success and involvement were differently predicted by the pretask appraisal and actual task performance. Thus self-appraisals that students experience after performing the task are not only influenced by the actual performance, but also by the task-related appraisal they form before the task, which is partially determined by their goal orientations. Cluster analysis revealed students with multiple goals, in whom learning and performance goals can work together to facilitate performance and motivation.     

Depressive self-presentation: beyond self-handicapping

An experiment was conducted to examine the notion that depressives' responses would reflect a protective self-presentation style (Hill, Weary, & Williams, 1986), the underlying goal of which would be the avoidance of future performance demands and potential losses in self-esteem. In this study, depressed and nondepressed Ss were asked to perform a relatively simple visual-motor task. Half of the depressed and half of the nondepressed Ss were told that if they were successful at the task, they would be asked to perform a 2nd, similar task. The remaining Ss were given no such expectation of future performance. We predicted and found that depressed compared with nondepressed Ss strategically failed at the task when presented with the possibility of future performance and further losses in esteem. Moreover, this strategic failure was associated with some costs; depressed-future performance expectancy Ss experienced more discomfort or negative affect as a result of their performance. The relationship between this depressive self-presentation and self-handicapping strategies is discussed.     

Personal information in searching for faces

Participants searched for a target on a television monitor either after they viewed pictures and received physical information about the target or received that information augmented by personal information. Based on a levels of processing perspective we predicted that the addition of personal information would stimulate deeper processing and result in better identification performance. Personal information did increase identification accuracy, as anticipated. Personal information also increased the duration of time spent on the search task relative to a distractor task, suggesting that personal information may have done more than deepen the processing at the time of encoding. In the current climate of terrorism, this increase in identification performance via a surveillance camera has clear applied significance.     

The effects of sex differences and evaluation on task performance and aspiration

An investigation was conducted of how evaluation differentially affects the performance and aspiration for future performance of 118 high school boys and girls. Subjects were selected to fit into either a superior or average intelligence group. In the high evaluation condition, subjects were instructed that their intelligence was being evaluated in anagram and visual-motor tasks they performed, while those in the low evaluation condition were instructed that the two tasks were being correlated. It was hypothesized that on a highly evaluated task, girls, when compared to boys, would show greater performance debilitation and would have lower aspirations for future performance. Although sex differences were found in performance debilitation and aspiration for future performance, they were not all in the predicted directions. Girls were equally debilitated in anagram performance under both evaluation conditions, while boys were debilitated in anagram performance only under high evaluation. When both boys and girls demonstrated a performance debilitation on the anagram task, their performance declined approximately 10%. No sex differences in performance were found on the visual-motor task. On both tasks, girls' aspirations were significantly affected by evaluation condition. The girls averaged 89% choosing the more difficult task in the low evaluation condition. Evaluation condition had no significant effect on aspiration for boys on either task. Intelligence showed no significant relationships.     

Effects of telic dominance and metamotivational state on squash task performance

Measures of telic dominance and metamotivational state were obtained from 40 volunteer males grouped on the basis of their playing ability, before and after the performance of squash tasks. Utilising a mixed-blocks design, which controlled for order of task, subjects were required to perform two squash tasks of differing difficulty. Significant differences between groups on performance were obtained, confirming the ability classification, but no significant differences in telic dominance were found. Significant increases in mood response in the telic direction were found on pre- and posttask scores. A significant decrease in discrepancy scores (preferred arousal minus felt arousal) obtained pre- and posttask was noted, together with a significant interaction between skill level and in arousal discrepancy pre- and posttask. In all cases trends were least for the most skilled group.     

Instruction effects on watch keeping in a “simple” vigilance task

Two experiments were conducted to determine the effect of variation in pretask instructions on performance on a simple vigilance task. In both experiments one group was told that the task would be challenging (Group C) and the other group, that the task would be monotonous (Group M). In Experiment 1 time-related decrements were found in the percentage of correct signal detections and in the number of incorrect responses. The results of Experiment 2 indicated time-related decrements, but no group differences, in percentage of correct detections. Group M also made progressively fewer false alarms, while false-alarm rates for GTOUP C did not change over time. Differences in mechanisms underlying performance decrements are discussed.     

Individual differences in the effects of personal space invasion: A test of the Brebner-Cooper model of extraversion

An experiment using invasion of personal space as a means of increasing arousal level tested the hypothesis that extraverts' performance at a relatively ‘inspective’ task would be impaired under conditions of increased arousal while they would perform better than introverts under more ‘responsive’ conditions. The role of N was examined. Results supported predictions drawn from the Brebner-Cooper (1974) model of extraversion.     

The attributional norm of internality and depressive sensitivity to social information

Two studies examined the existence, within an achievement-related context, of a social norm favoring internal explanations for task performances. In the first study, we investigated the reactions of observers to an actor's high, moderate, or low self-attribution of causal responsibility for his negative performance outcome on an ostensibly standardized aptitude test. The results indicated that the actor was evaluated more positively to the degree that he accepted more personal responsibility for his performance. In the second study, we examined the reactions of depressed and nondepressed observers to an actor's high or low self-attributions of causal responsibility for his poor performance on a test of analytical ability. On the basis of the notion that the chronic lack of control and resultant uncertainty, presumably characteristic of depressed persons, motivates attributional information processing, we expected depressed observers to be more sensitive to the actor's violation of the norm of internality and to respond with more social disapproval than nondepressed observers. Results generally were consistent with this reasoning. Experimental findings are discussed in terms of the interpersonal implications of expressed attributions.     

Individual differences in higher-level cognitive abilities do not predict overconfidence in complex task performance

Even when people perform tasks poorly, they often report unrealistically positive estimates of their own abilities in these situations. To better understand the origins of such overconfidence, we investigated whether it could be predicted by individual differences in working memory, attentional control, and self-reported trait impulsivity. Overconfidence was estimated by contrasting objective and subjective measures of situation awareness (the ability to perceive and understand task-relevant information in the environment), acquired during a challenging air traffic control simulation. We found no significant relationships between overconfidence and either working memory or attentional control. However, increased impulsivity significantly predicted greater overconfidence. In addition, overall levels of overconfidence were lower in our complex task than in previous studies that used less-complex lab-based tasks. Our results suggest that overconfidence may not be linked to high-level cognitive abilities, but that dynamic tasks with frequent opportunities for performance feedback may reduce misconceptions about personal performance.     

Facilitated cognitive disengagement in depression

The present study was conducted to test predictions derived from the hypothesis that depression may serve the purpose of adaptively facilitating disengagement from obsolete cognitive plans. Groups of students with either low or high depression scores were contrasted using a procedure that featured an initial learning phase, within which participants learned to perform a task, followed by a relearning phase within which they needed to disengage from initial learning in order to relearn to perform an altered task. It was assumed that performance in the relearning phase would be affected by the degree to which participants could readily disengage from their initial learning. As predicted, participants in the high depression group, relative to those in the low depression group, demonstrated superior performance in the relearning phase alone. The theoretical and applied implications of this finding are discussed.     

Social loafing and social compensation: the effects of expectations of co-worker performance

Previous research has suggested that people tend to engage in social loafing when working collectively. The present research tested the social compensation hypothesis, which states that people will work harder collectively than individually when they expect their co-workers to perform poorly on a meaningful task. In 3 experiments, participants worked either collectively or coactively on an idea generation task. Expectations of co-worker performance were either inferred from participants' interpersonal trust scores (Experiment 1) or were directly manipulated by a confederate coworker's statement of either his intended effort (Experiment 2) or his ability at the task (Experiment 3). All 3 studies supported the social compensation hypothesis. Additionally, Experiment 3 supported the hypothesis that participants would not socially compensate for a poorly performing co-worker when working on a task that was low in meaningfulness.     

Cognitive effects of life stress and learned helplessness

Abstract Stressful life events and learned helplessness attributional styles have been shown to impact a variety of personal outcomes. This study examined how these factors influence two classes of cognitive behaviors: the occurrence of intrusive thoughts and performance in memory and verbal-spatial reasoning tasks. Negative life change and attributions for negative events predicted different types of cognitive responses. Individuals reporting higher levels of life stress were more likely to experience distracting thoughts that were unrelated to the current task, whereas individuals with learned helplessness attributional styles tended to have more worrisome thoughts about their task performance. In general, individuals reporting high levels of negative life stress tended to perform more poorly in tasks, whereas individuals with learned helplessness attributional styles tended to perform better than those who did not share this explanatory style. These results suggest that life stress and attributional style have important influecnes on cognitive processes, and that a learned helplessness attributional style can have beneficial effects on behavior in some situations.     

Personal importance, motivation, and performance of older adults.

This investigation was conducted to examine whether older adults would improve their performance when given statements intended to make them feel important to a research study as well as statements concerning their over-all well-being. Women (n = 14) and men (n = 15) with mean ages of 76.0 yr. and 75.1 yr., respectively, were randomly assigned into a control group, a positive reinforcement group, and a group given statements of personal importance. Dependent measures on a rotary pursuit task, screw-and-nut assembly task, and an interest questionnaire were obtained during three separate visits. Data were analyzed with a 3 x 3 (Groups x Days) analysis of variance. While no significant group effects were found on any measure, a significant main effect was obtained for days, indicative of learning.     

Discrepancy-plus-search processes in prospective memory retrieval

In the present study, we investigated the processes underlying prospective memory (PM) retrieval, focusing specifically on two possible spontaneous processes: discrepancy-plus-search and familiarity. Discrepancy was elicited by orthogonally manipulating the processing difficulties of the PM targets and the nontargets. Participants performed a PM task while solving anagrams with two levels of difficulty (easy or difficult). Assuming that the ease of processing easy anagrams would heighten a sense of familiarity, the familiarity view predicted better PM performance with easy anagrams as the PM targets. In contrast, the discrepancy-plus-search view predicted higher PM performance for the PM targets that were anagrams whose difficulty level mismatched that of the surrounding nontargets, as compared to PM targets whose difficulty matched that of the surrounding nontargets. This prediction was based on the idea that mismatching rather than matching difficulty levels would create discrepancy, thereby signaling significance for the target. Participants were more likely to perform the PM task for PM targets that were discrepant, supporting the discrepancy-plus-search view.     

Task predictability and performance as determinants of confidence in multiple-cue judgments

Two experiments were performed in order to study judges' confidence in their judgments. Experiment I showed that judges' confidence is a direct function of the cue intercorrelation. r_ij in a pure judgmental task. When judges recieved feedback, the effect of r_ij on confidence was, as predicted, reduced. Confidence was, however, systematically related to neither R ²_c nor performance in the feedback condition. Experiment II was a further study of the effect of feedback on confidence. In addition, the hypothesis that the lack of relation between performance and confidence is due to judges' poor knowledge of how they actually perform in probabilistic inference tasks was tested. The experiment showed that differences among judges' confidence is a direct function of task predictability and that judges' confidence is related to how they believe that they perform rather than to how they actually perform. The theoretical as well as the practical importance of studies of confidence in probabilistic inference tasks was discussed.     

Time Urgency and Job Performance: Field Evidence of an Interactionist Perspective1

Individual predispositions toward time urgency were assessed among 118 emergency room nurses and 145 small‐town librarians. Following from research on person–job fit, according to which people perform better when the demands of the situation match their individual characteristics than when these are mismatched, it was hypothesized that nurses (who typically face high time‐urgent demands) would perform better when they scored high in time urgency, and that librarians (who typically face low time‐urgent demands) would perform better when they scored low in time urgency. The results, based on a standardized measure of task performance, were precisely as expected. The practical ramifications of these findings are discussed along with the implications for research on person–job fit.     

The role of goal specificity in the goal-setting process

The purpose of this study was to investigate the relationship between goal specificity and task performance, with specificity operationalized as a continuous quantitative variable reflecting the range of performance levels individuals chose as their personal goals. It was hypothesized that, controlling for goal difficulty, specific personal goals would be associated with higher levels of task performance. It was also hypothesized that task strategy would mediate the relationship between goal specificity and performance and that specific goals would be associated with smaller goal-performance discrepancies. The results from a sample of 162 college students working on an eye-hand coordination task supported the hypothesis concerning goal-performance discrepancies. They hypotheses regarding task strategy and the relationship between goal specificity and performance were supported only on the second of two trials.     

Self-presentation: managing the impression of consistency when reality interferes with self-enhancement.

The manner in which an individual's self-perceptions affect related self-presentations was investigated. One hundred and twenty subjects believed that they would participate in a group task where their individual performance would either be known to the group or be completely anonymous. On the basis of bogus feedback from prior tests, subjects expected to perform either extremely well or very poorly on the group task; control groups received no such feedback. Before the task began, group members exchanged personal information that allowed them to vary their self-presentations. Factor analysis revealed two self-presentational factors: competence and interpersonal relations. A Performance Expectations X Anonymity interaction was obtained on self-presentational claims to personal competence. Under public performance conditions (where future public events could invalidate an unrealistically positive self-presentation), self-presentations were consistent with subjects' expectations of actual performance. However, under anonymous conditions, self-presentations were quite favorable and unaffected by expectations of actual performance. The results support an incentive model and fail to support a consistency model. Subjects seemed to desire as self-enhancing and approval gaining a public image as possible but conceded to the demands of public reality when necessary.     

Transportation,Stress, and Community Psychology

Conditions of transportation were investigated as sources of psychological stress as they affect the physiology, task performance, and mood of commuters. Participants in the study were 100 employees of industrial firms. Traffic congestion was construed as a behavioral constraint in terms of the concept of impedance which is defined by the parameters of distance and time. It was expected that the effects of impedance would be mediated by personality factors, such as locus of control. Multivariate tests of the internal validity of the impedance factor were significant. However, significant main effects for impedance were obtained only for mood and residential adaptation. The predicted interactions of impedance with locus of control were obtained across task performance indices. In multiple regression analyses, the distance and speed of the commute to work were found to account for significant proportions of variation in blood pressure, while several indices of personal control had significant regression effects on the task measures. The implications of the results for research in community psychology are discussed.
