Individual differences in anxiety level and eyewitness memory.

The present study investigated the relationship between individual differences in anxiety and eyewitness performance. Instructions designed to produce evaluative threat were given to anxious and nonanxious subjects at encoding and/or at retrieval. The performance of those subjects who were given anxiety-arousing instructions at encoding and retrieval and who scored high on the Test Anxiety Scale (TAS; Sarason, 1972) was less accurate on an eyewitness task than was that of the subjects who scored low on the scale. This difference in performance was attributable to improvement in the performance of nonanxious subjects, rather than debilitation in the performance of anxious subjects. Faced with the threat of failure, low-anxious subjects appeared to have the potential for increased effort. High-anxious subjects seemed to perform at or near capacity under all the experimental conditions because of their predisposition for task-irrelevant worry, which limited the possibility of an increase in working memory capacity.     

Effects of test anxiety,ego stress,and attentional skills training on arithmetic reasoning: An experimental evaluation of a brief counseling strategy

Abstract

Two hundred forty high school students (120 male and 120 female) in India performed a moderately difficult multiple choice Arithmetic Reasoning task after undergoing short-term (40 minutes) cognitive treatment in the form of Attentional Skills Training. A 2 × 2 × 2 (Test Anxiety x Attentional Skills Training x Stress) design with separate analysis for boys and girls indicated these results: with intervention the high anxiety subjects under ego stress conditions, compared to their high-anxious control, low-anxious ego stress, or low-anxious control counterparts, reported the maximum significant improvement in performance on the Arithmetic Reasoning test. The low-anxiety subjects performed consistently well with or without treatment or stress conditions. The findings shed new light on the attentional theory of test anxiety, and it was reasoned that long-term effects of cognitive treatment be studied by using varied performance tasks (difficulty level controlled) on different gender and age groups across cultures.

Anxiety symptom interpretation and performance expectations in high-anxious,low-anxious,defensive high-anxious and repressor individuals

To date, no research has investigated score predictions and anxiety interpretation in high-anxious, low-anxious, defensive high-anxious and repressor individuals. This study examined Eysenck’s (1997) predictions for cognitive biases on future performance expectations in all four groups. This study was conducted in an ecologically-valid sporting environment. Competitive shooters completed the Marlowe–Crowne Social Desirability Scale and the Sport Anxiety Scale prior to a major competition. Percentile splits identified the four defensiveness/anxiety groups. The modified Competitive Sport Anxiety Inventory-2 was used to assess the intensity and direction of anxiety prior to competition. Participants predicted their expected shooting score. The hypothesis that repressors would interpret their anxiety as more facilitative to performance compared to low-anxious individuals was partially supported. Repressors were more optimistic in their performance prediction in contrast to defensive high-anxious performers who, in turn, were more pessimistic compared to the other two groupings. High-anxious performers, contrary to predictions, demonstrated optimism in their future performance. The findings of this study corroborate the theoretical predictions and the evidence from previous studies with sport performers. Future research should continue to investigate the influence of cognitive biases on performance predictions in sporting environments using Weinberger et al.’s classifications.     

Anxiety and Repression in Attention and Retention

High- and low-anxious college students (as determined by scores on the Taylor Manifest Anxiety Scale; A. W. Bendig, 1956) and repressors (low anxiety and high scores on the Marlowe–Crowne Social Desirability Scale; D. P. Crowne & D. Marlowe, 1964) were compared on 3 cognitive tasks. High-anxious participants more often spelled the negative emotional meaning of ambiguous homophones (e.g., pane/pain) and forgot more of their free associations to emotional cue words than did the low-anxious participants. The repressors also detected the emotional meaning of the homophones but unlike the anxious, the repressors did recall their associations to the emotional words. In a working memory task using nonemotional items, the moderately anxious participants recalled fewer words than did the low- and high-anxious participants. The results confirm that both trait anxiety and repression affect information processing at a variety of stages but not in the same way. Repressors were sensitive to, and retentive of, negative emotional stimuli.     

Effects of age and anxiety on episodic memory: selectivity and variability

Selective age-related differences in source memory relative to item memory, and individual differences in memory performance in relation to anxiety were explored with high- and low-anxious subjects screened from normal young and elderly adults. They were read false facts about the locations of well-known and unknown sights in a male or female voice. Intentional and incidental learning instructions were administered for source memory. Selective age-related deficits in source memory were observed under both encoding conditions. Higher level of anxiety was related to lower memory performance only in the old group; this relation was stronger in source recall. The findings suggest that the presence of such selectivity is unrelated to the tradeoff between item encoding and source encoding. Anxiety affects the variability, and mediates the selectivity of age effects on episodic memory.

Re‐examining the effects of noncontingent success on self‐handicapping behaviour

Background: Self‐handicapping refers to the practice on the part of certain individuals to handicap their performance when poor performance is likely to reveal low ability. Noncontingent success (feedback that is inflated relative to performance) is more likely to promote self‐handicapping behaviour than noncontingent failure (failure feedback based on false or misleading information). However, the reasons for the differing effects of these forms of performance feedback on self‐handicapping behaviour remain obscure. Aims: The present study sought an explanation for the differing effects of these forms of performance feedback, testing the assumption that students high in self‐handicapping behaviour would react more negatively following noncontingent success, reporting more unstable and external attributions, higher anxiety, and a greater propensity to claim handicaps than those low in self‐handicapping behaviour. No differences were expected on any of these measures for high relative to low self‐handicappers following either noncontingent failure or success. Sample: Participants were 72 undergraduate students, divided equally between high and low self‐handicapping groups. Method: High and low self‐handicappers were assigned to one of three performance feedback conditions: noncontingent failure, success and noncontingent success. High and low self‐handicappers were then given an opportunity to claim handicaps prior to completing measures of attributions and state anxiety. Subsequently, they completed 12 remote associate tasks, serving as an assessment of performance, and 16 unicursal tasks, assessing practice effort. Results: Following noncontingent success, high self‐handicappers reported greater anxiety, more unproductive attributions and claimed more handicaps than low self‐handicappers. However no differences were evident for high and low self‐handicappers following either noncontingent failure or success. High self‐handicappers also performed poorly on the remote associates tasks and reduced practice effort on the unicursal tasks.     

Self-esteem and the effects of success and failure feedback n performance

High and low self-esteem subjects received success or failure feedback regarding their performance on a task described as measuring their sensitivity to other people. Presumably as part of another study, changes in their self-perceptions regarding sensitivity to others were assessed, as well as changes in their performance on a different task Changes in self-perception were greater when the feedback was consistent with subjects' overall level of self-evaluation Task performance following failure was poorer than that following success HSE subjects performed better following success feedback, and LSE subjects performed more poorly following failure There were no significant performance changes for the HSE-failure and LSE-success subjects. The degree of change in self-perception of sensitivity to others was highly correlated with the magnitude of performance changes     

Effort,aversive representations and performance in test anxiety

The effects that effort and attention to aversive representations have on performance are analysed. Effort is manipulated by monetary incentives, and aversive representations are provoked by test and failure conditions. The most difficult items of the task—an inductive non-verbal reasoning test—are performed more poorly by high-trait-anxious Ss under test conditions with reward than by low-anxious Ss, but they do not differ under test instructions without reward. And there are no differences in the less difficult items. These results lend support to Eysenck's conceptualization on the effects of anxiety on performance effectiveness and on processing efficiency. Alternative interpretations are discussed.     

Sensory feedback in the learning of a novel motor task

The role of different forms of feedback is examined in learning a novel motor task. Five groups of ten subjects had to learn the voluntary control of the abduction of the big toe, each under a different feedback condition (proprioceptive feedback, visual feedback, EMG feedback, tactile feedback, force feedback). The task was selected for two reasons. First, in most motor learning studies subjects have to perform simple movements which present hardly any learning problem. Second, studying the learning of a new movement an provide useful information for neuromuscular reeducation, where patients often also have to learn movements for which no control strategy exists. The results show that artificial sensory feedback (EMG feedback, force feedback) is more powerful than "natural" (proprioceptive, visual, and tactile) feedback. The implications of these results for neuromuscular reeducation are discussed.

When Audience Presence Is Enjoyable: The Influence of Audience Awareness of Prior Success on Performance and Task Interest

Subjects received positive feedback on a practice anagram task and then performed a similar task in front of either an audience that was aware of their prior success or an audience that was unaware of their prior success. Two control conditions were included in which subjects performed alone after receiving positive feedback or performed alone without feedback. Results indicated subjects' task interest and performance increased under conditions in which they performed in front of unaware audiences. In addition, subjects' task interest and performance levels decreased in the presence of audiences that were aware of their prior success. These results point to an important role of audience awareness in setting performance standards and expectations. These findings are interpreted from a resource-investment analysis of task value and performance. Implications for surveillance in public settings and in the workplace (e.g., automated computer monitoring) are discussed.     

The discrepant repressor: differentiation between low anxiety, high anxiety, and repression of anxiety by autonomic-facial-verbal patterns of behavior

This study examined the notion that personality questionnaires can be used to predict different styles of coping with anxiety as expressed by individual differences in patterns of autonomic, verbal, and nonverbal reactions. In line with earlier modifications of the repression-sensitization concept, the Taylor Manifest Anxiety Scale (MAS) and the Marlowe-Crowne Social Desirability Scale (SDS) were used to select four groups of 12 subjects each from a pool of 206 male students in Germany: low-anxious subjects (low MAS, low SDS), repressors (low MAS, high SDS), high-anxious subjects (high MAS, low SDS), and defensive high-anxious subjects (high MAS, high SDS). Several measures of autonomic arousal, facial activity, and self-reported affect were obtained during a potentially anxiety-arousing free-association task and during a number of control conditions, including a funny film. Significant differences in baseline-corrected heart rate and self-reported anxiety as well as rated facial anxiety all indicated that repressors exhibited a discrepancy between low self-reported anxiety and high heart rate and facial anxiety; low-anxious subjects reported an intermediate level of anxiety, although they showed low heart rate and facial anxiety; high-anxious subjects had consistently high values on all three variables; and the defensive high-anxious group showed an intermediate level of anxious responding. These group differences were specific to the task of freely associating to phrases of mixed (sexual, aggressive, neutral) content (but not to other experimental situations) and to self-reported anxiety (but not to other self-rated emotions or task difficult), indicating that they reflect individual differences in coping with anxiety.     

Effects of active and passive EMG biofeedback training on performance of motor and cognitive tasks.

The goal of this study was to compare the effects of general relaxation (passive group) and neuromuscular tension control (active group), both using EMG biofeedback techniques, on the performance of memorization, simple reaction time, and rotary pursuit. 18 subjects were given five consecutive daily sessions of training or were placed under control conditions, after which their performance on these various tasks was evaluated. Results indicate that control of neuromuscular tension seemed to facilitate performance on all tasks over that of the control group. Except for simple reaction time, there was no difference between the "active" and "passive" groups. The results are interpreted in terms of factors in selection of subjects and experimental conditions.     

Locus of control and effects of failure on perfomance and perceived competence

Reactions to related performance feedback of 117 internal and external eighth-grade children were investigated under conditions which made denial of personal responsibility for outcomes difficult. Both internals and externals were equally pleased by success feedback and displeased by failure and their competence judgement was influenced by the feedback received. However, internals exhibited more effective coping with failure than did externals. They improved their performance following failure feedback relatively more than after success and no external feedback conditions, and their percieved competance did not decrease in comparison with externals.     

Treadmill Gait Analysis Characterizes Gait Alterations in Parkinson's Disease and Amyotrophic Lateral Sclerosis Mouse Models

The effect of anxiety on learning and performance of a complex motor task was determined. In addition the effects of two stressors—competition and failure—and the interactions between these stressors and anxiety were investigated. 40 high and 40 low anxiety Ss (selected by the Taylor Manifest Anxiety Scale) learned and performed a coincident timing task. Competition was presented by offering the Ss a monetary reward for the best performance, while failure was manipulated by giving false knowledge of results and indicating that the performance level was inferior. Results showed that Ss low in anxiety performed significantly better than Ss high in anxiety during the initial learning of a complex motor task. No difference was found between Ss extreme in anxiety once the task was well-learned. Competition and failure did not affect performance or interact with the anxiety level of Ss.     

Anxiety symptom interpretation in high-anxious, defensive high-anxious, low-anxious and repressor sport performers

For the first time in a sport setting this study examined the intensity and direction of the competitive state anxiety response in collegiate athletes as a function of four different coping styles: high-anxious, defensive high-anxious, low-anxious and repressors. Specifically, the study predicted that repressors would interpret competitive state anxiety symptoms as more facilitative compared to high-anxious, defensive high-anxious, and low-anxious performers. Separate Multivariate Analyses of Variance (MANOVA) were performed on the intensity and direction subscales of the modified Competitive State Anxiety Inventory-2 (CSAI-2). A significant main effect was identified for trait worry revealing that low trait anxious athletes reported lower intensities of cognitive and somatic anxiety and higher self-confidence and interpreted these as more facilitative than high trait anxious athletes. The prediction that performers with a repressive coping style would interpret state anxiety symptoms as more facilitative than performers with non-repressive coping styles was not supported.     

Self-esteem and responses to success and failure: Subsequent performance and intrinsic motivation

A model is proposed in which the goal of people with high self-esteem is to cultivate personal strengths in order to excel, whereas the goal of people with low self-esteem is to remedy personal deficiencies in order to become adequate In two experiments, subjects received initial outcome feedback of either success, humiliating failure (internal attribution), or failure that allowed face-saving (external attribution) Experiment 1 then measured subjects intrinsic motivation to pursue the task during free-choice time Subjects with high self-esteem had the highest intrinsic motivation after success Subjects with low self-esteem had the highest intrinsic motivation after the humiliating failure Experiment 2 required a second performance on a similar task Performance results were consistent with the intrinsic motivation results of Experiment 1, with one exception High self-esteem subjects were sensitive to the different failure treatments, performing well after humiliation but poorly after face-saving Subjects with low self-esteem performed the same in both failure conditions The relation of the present model and results to previous work is discussed
