Effect of fear arousal upon task performance and verbal behavior.

80 undergraduate females were classified as being either high or low in fear of speaking in front of a group. ? were told that they were to speak following a task; the remaining Ss did the task without expecting to speak. All Ss spoke about the task for 1 min. immediately following the task. Experimental Ss took significantly longer to perform the task, and naive judges were able to detect differences in the verbal productions of the groups. Formal aspects of S's verbal productions also discriminated among high- and low-fear Ss. Implications for theory and importance of assessing different types of behavior are briefly discussed.

Effects of physiological arousal level, frustration, and task complexity on performance.

This paper investigates the effects of initial heart-rate level, frustration, and task complexity on digit-symbol performance. Low (LD) and high (HD) heart-rate Ss worked on a digit-symbol problem immediately before and after a frustration manipulation which raised heart rate about 20 beats/min. The results indicated that HD Ss achieved higher initial performance scores than LD Ss on tasks of relatively low complexity; however, following frustration LD Ss manifested a significantly greater increment in performance than HD Ss. The latter group showed a trend toward a decrement in performance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Don't look down: Emotional arousal elevates height perception.

In a series of experiments, it was found that emotional arousal can influence height perception. In Experiment 1, participants viewed either arousing or nonarousing images before estimating the height of a 2-story balcony and the size of a target on the ground below the balcony. People who viewed arousing images overestimated height and target size more than did those who viewed nonarousing images. However, in Experiment 2, estimates of horizontal distances were not influenced by emotional arousal. In Experiment 3, both valence and arousal cues were manipulated, and it was found that arousal, but not valence, moderated height perception. In Experiment 4, participants either up-regulated or down-regulated their emotional experience while viewing emotionally arousing images, and a control group simply viewed the arousing images. Those participants who up-regulated their emotional experience overestimated height more than did the control or down-regulated participants. In sum, emotional arousal influences estimates of height, and this influence can be moderated by emotion regulation strategies. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Repeated frustrations and expectations in hostility arousal.

"Two experiments were devised to test predictions developed on the basis of an earlier investigation… . (wherein) it was found that the partner's act had its greatest effect on S's final attitude toward him when it was inconsistent with the partner's earlier behavior… . The… experiment reported here… obtained essentially similar results… (suggesting) that unexpected frustrations produce a stronger aggressive reaction than anticipated frustrations because, as a result of the hypothesized contrast effect, the former probably are evaluated as being more severe."

"Self Verbalization and Emotional Arousal": Erratum.

Reports an error in the original article by David C. Rimm and Stuart B. Litvak (Journal of Abnormal Psychology, 1969[April],74[2],181-187). On page 187 of the article corrections need to be made in the first and second paragraphs. (The following abstract of this article originally appeared in record 1969-09037-001.) Investigated certain assumptions derived from A. Ellis' theory relating implicit verbalization to emotional arousal. Emotional responses (GSR and respiration changes) of 18 undergraduates instructed to silently read sequences of affectively loaded sentences were compared with those of 9 Ss who read neutral sentences. The relationship between relevance to S of the content of the sentences and level of emotional response was investigated, as was the effect of sentence type (observation, inference, or evaluative conclusion) on level of emotional response. Results were that Ss showed a significantly greater response to affectively loaded than to neutral sentences on 2 out of 3 responses measures. Neither relevance nor sentence type were found to have any significant effect. Results were interpreted as offering only partial support for the theory.

The effect of motivation arousal on humor preferences.

"The present experiment was designed to test the hypothesis that the arousal of different types of motivations would produce differences in humor preferences. It was predicted that in a hostility-arousing situation subjects would prefer humorous material of a hostile and aggressive nature, while subjects placed in a sexually arousing situation would prefer humor material with a sexual theme. This prediction was confirmed… [and] an explanation of the results was offered in terms of suppression." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attentional task aptitude and performance anxiety.

Anxious responding (trait, state, and test anxiety) has a negative impact on overt performance. Researchers have used a unidimensional method of assessing anxiety and performance, although a more informative approach would involve a comprehensive assessment battery and multiple performance tasks. Incorporating this strategy, the authors measured the impact of anxiety on 4 attentional processing tasks. Results revealed that "types" of anxiety symptoms were differentially related to attentional task performance; test anxiety accounted for the most variance in predicting performance on the Wechsler Adult Intelligence Scale-Third Edition (D. Wechsler, 1997) letter-number sequencing and digit-span subtests, trait anxiety and fear of negative evaluation were more significant in predicting Stroop performance, and math anxiety accounted for the largest variance toward understanding Paced Auditory Serial Addition Task (C. W. Lejuez, C. W. Kahler, & R. A. Brown, 2003) scores. Theoretical and clinical implications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Group performance in a cognitive task.

On a cross-word puzzle task performed by 60 pairs of male Ss, correlations between group performance and performance of the individuals (independently determined) were calculated. 82% of the true group performance variance on the task could be predicted from the individual performance scores. "It is suggested that the nature of the task is important in studies of group performance, and that the existence of 'group' phenomena should be empirically demonstrated rather than assumed."

Relationship between projective and direct measures of fear arousal.

The present study reports on the use of a projective measure which in 2 independent replications appeared to be a valid measure of level of induced fear, and which showed a high correlation (+.75) with a direct response scale. However, the data suggest that despite the magnitude of their relationship, the 2 measures are differentially sensitive to expressions of motivation which reflect the Ss' general style of defensive emotional response. Ss who reported themselves as being reticent in expressing their feelings of pain showed greater fear arousal on the projective measure than on the direct measure, while the opposite was true of Ss who reported that they were likely to express their pain to others (p     

Conductance levels during vigilance task performance.

Using apparatus similar to the Mackworth "clock" test, 9 Ss provided conductance trends over a 2-hour session. Cluster analysis revealed 3 clusters: ascending in 4 Ss, descending in 3 Ss, and cyclical in 2 Ss. "No significant differences were found between the performances of these three clusters nor between high and low conductance groups. The results suggest, however, that higher conductance level is associated with better performance." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effect of immediately preceding task brightness on visual performance.

To determine how visual performance at low photopic brightness levels is affected by the brightness of an immediately preceding visual task, Ss were required to read photographs of banks of instrument dials (a near-vision task) and banks of Landolt rings (a far-vision task) after adaptation to the brightness level of the first task, under speed and accuracy instructions. The Ss performed both the near and far tasks. Within the brightness ranges used, performance was related to the brightness of the task but not to the brightness of the immediately preceding task.

Schizophrenic performance in a word-communication task.

Speaker and listener skills in schizophrenic and in normal Ss were studied using a communication task in which the speaker provides clue words to distinguish referent from nonreferent stimuli, and the listener chooses the speaker's referent from each stimulus array on the basis of the speaker's clue words. 4 groups of 18 speaker-listener pairs were used: schizophrenic speakers-schizophrenic listeners; schizophrenic speakers-normal listeners; normal speakers-schizophrenic listeners; normal speakers-normal listeners. Analysis of accuracy scores (proportion correct referent choices) showed that schizophrenic speakers were inferior to normals (p     

Variability of performance in a vigilance task.

An experiment was conducted to determine the effect of signal pattern and frequency on the variability of S's performance in a vigilance task. Ss were 12 male college students who watched 3 dials during 3 consecutive 27-min. periods. Real signals occurred alone in 1 period while 2 different patterns of dummy signals were added in the other 2 periods. It was found that dummy signals which occurred at semiregular intervals were more effective in reducing S's variability than those which occurred at nonregular intervals. It was also found that variability increased with time. It is concluded that use of a semiregular pattern of dummy signals would be one way of improving performance on a vigilance task.

The influence of degree of expertise and objective task complexity on perceived task complexity and performance.

Research on expertise has shown that nonexperts may sometimes outperform experts. Some researchers have suggested that superior performance by experts depends on the match between the experts' cognition and the demands of the task. The authors explored this issue using a quasi-experiment set in an organization. They examined how 3 sets of similar tasks that differ in their type of complexity can lead to differences in task perceptions and performance among experts, intermediates, and novices. The results suggest that experts and novices pay attention to different aspects of a task and that this affects both their perceptions of task complexity (i.e., task analyzability and variability) and their performance on the task.

Emotional dissonance, burnout, and in-role performance among nurses and police officers.

Two studies including 108 nurses and 101 police officers tested the proposition that emotionally demanding interactions with recipients may result in emotional dissonance, which, in turn, may lead to job burnout and impaired performance. More specifically, on the basis of the literature on burnout and emotional dissonance, the authors hypothesized that emotional job demands would explain variance in burnout (i.e., exhaustion and cynicism/disengagement) through their influence on emotional dissonance. In addition, the authors predicted that emotional dissonance would be (negatively) related to in-role performance through its relationship with burnout. The findings of a series of structural equation modeling analyses supported both hypotheses. The implications for research and practice are discussed, as well as avenues for additional research.

The influence of task complexity and practice on performance after loss of sleep.

An experiment was conducted to assess the effects of degrees of task complexity and practice on performance after loss of sleep. The Ss were automatically presented every 7 sec. for 23 min., with cards containing 6 symbols. A symbol had to be chosen on the basis of certain rules. Some cards required 1 rule, some 2, some 3, and some 4. Group 1 was practiced after normal sleep and tested after 22 and 46 hr. without sleep. Group 2 was tested without sleep and without previous practice. Group 3 was practiced and tested after normal sleep. Loss of sleep had a greater effect after practice, but no clear differences emerged between the different levels of task complexity. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effect of variation in task complexity and displayed information on operator performance.

An experiment was conducted to determine the effects of amount of information displayed, level of task difficulty, and practice on performance speed and accuracy for a visual motor task. Based on results from 16 Ss, it was concluded that an increase in the number of cues available for visual reference will not necessarily affect performance. Further cooroborative evidence was obtained for the hypothesis that the criterion of redundancy in displayed information should be based on perceptual usefulness of the cues provided.

The relative importance of task and contextual performance dimensions to supervisor judgments of overall performance.

Although evidence supports the unique contribution of task performance and contextual performance to overall evaluations, little is known about the relative contribution that specific dimensions of contextual performance make to overall performance judgments. This study evaluated the extent to which supervisors consider task and contextual performance by using relative weights (J. W. Johnson, 2000) to statistically describe the relative importance of specific dimensions of each type of performance to overall performance ratings. Within each of 8 job families in a large organization, each of 4 dimensions of contextual performance made not only a unique contribution but a relatively important contribution to the overall evaluation. Evidence also supports the adaptive performance dimension of handling work stress as an aspect of contextual performance and job–task conscientiousness as an aspect of both task and contextual performance.

Implicit affective cues and attentional tuning: An integrative review.

A large and growing number of studies support the notion that arousing positive emotional states expand, and that arousing negative states constrict, the scope of attention on both the perceptual and conceptual levels. However, these studies have predominantly involved the manipulation or measurement of conscious emotional experiences (e.g., subjective feelings of happiness or anxiety). This raises the question: Do cues that are merely associated with benign versus threatening situations but do not elicit conscious feelings of positive or negative emotional arousal independently expand or contract attentional scope? Integrating theoretical advances in affective neuroscience, positive psychology, and social cognition, the authors propose that rudimentary intero- and exteroceptive stimuli may indeed become associated with the onset of arousing positive or negative emotional states and/or with appraisals that the environment is benign or threatening and thereby come to moderate the scope of attention in the absence of conscious emotional experience. Specifically, implicit “benign situation” cues are posited to broaden, and implicit “threatening situation” cues to narrow, the range of both perceptual and conceptual attentional selection. An extensive array of research findings involving a diverse set of such implicit affective cues (e.g., enactment of approach and avoidance behaviors, incidental exposure to colors signaling safety vs. danger) is marshaled in support of this proposition. Potential alternative explanations for and moderators of these attentional tuning effects, as well as their higher level neuropsychological underpinnings, are also discussed along with prospective extensions to a range of other situational cues and domains of social cognitive processing.

Leader's contribution to task performance in cohesive and uncohesive groups.

Army tank crews, B-29 bomber crews, antiaircraft artillery crews, and creative discussion groups provided data which were analyzed to determine the relationship between the leader's intelligence and group performance. Each sample was divided into cohesive and uncohesive groups, and the correlation between the leader's intelligence and group performance was computed. The results indicated consistently that the leader's intelligence predicts group performance in cohesive groups, but not in uncohesive groups.
