Training for Dangerous Task Performance: The Effects of Expectations and Feedback1

The training of individuals to perform dangerous tasks confronts theorists and practitioners with a critical issue: To what extent should individuals be exposed during training to stressors that characterize the conditions under which the task will eventually be performed? The present study evaluated two variables that might help resolve this dilemma. The first, a personality variable, consists of a person's generalized expectation that he or she will not be physically hurt while exposed to danger. The other, which is more sitution-specific, consists of the feeling of success or failure that the trainee experiences at the conclusion of training under physically dangerous conditions. The quality of soldiers' performance and the intensity of experienced stress were tested in a combat simulation. Individuals who tend to assign a low probability to their being physically injured in dangerous situations were found to benefit more from dangerous than from non-dangerous training. The opposite was found for individuals who assign a high probability to their being injured in dangerous situations. Moreover, exposure to serious physical threats during training yielded better training results than training that did not involve such threats only when the subjects concluded their training with a feeling of success. The subjective feelings of success or failure had no effect, however, under training conditions that did not expose trainees to danger. Theoretical and practical implications of these findings are discussed.     

The Contribution of Task Performance and Contextual Performance to Effectiveness: Investigating the Role of Situational Constraints

Task performance and contextual performance are two distinct dimensions of behaviour at work that can contribute independently to effectiveness outcomes for organisations. Contextual performance is important because it represents a type of behaviour that is largely under the motivational control of individuals. Little research has addressed how the opportunity to engage in contextual behaviours might be constrained by situational demands. This study examined the contribution of task performance and contextual performance to effectiveness in the work of air traffic controllers. As predicted, task difficulty moderated the relationship between contextual performance and effectiveness. The results demonstrate that contextual performance does contribute to effectiveness in technical domains, such as air traffic control, and highlight the importance of assessing situational factors when assessing performance and effectiveness.     

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.     

Putting Organizational Effectiveness Into Practice: The Preeminent Consultation Task

Successful consultation relies on the consultant's ability to conceptualize the operations of the total organization. An overview of the theoretical and practical applications of the construct “organizational effectiveness” (OE) is presented in relation to consultation. Barriers limiting earlier conceptualizations and applications of the construct are identified and discussed. A model of OE that melds open systems, organizational, and consultation theories is presented as a tool for guiding maximally beneficial consultation interventions. The implications of this model for consultation practice, advancing theory and research, and professional ethics are discussed.     

Quiet Eye Training: Effects on Learning and Performance Under Pressure

The aim of this study was to examine the efficacy of quiet eye (QE) training in optimizing the learning and performance under pressure of novices in a putting task. Fourteen participants performed 40 pre-test putts and were randomly allocated into a QE training or control group. They then performed 320 acquisition phase putts and a further 120 test putts in a retention-transfer (pressure)-retention design. The QE-trained group maintained more effective attentional control and performed significantly better in the pressure test compared to the control group. Furthermore, longer QE periods were associated with better performance across all test putts.     

Control and Anticipation of Social Interruptions: Reduced Stress and Improved Task Performance1

Social interruptions are frequent occurrences that often have distressing consequences for employees, yet little research has gauged their effect on individuals. Participants were exposed to 2 social interruptions as they engaged in a computer task with an accepted performance goal. Participants who were able to anticipate social interruptions performed significantly better than did those who could not anticipate them. Participants who had the opportunity to prevent interruptions reported significantly less stress than those who did not have this opportunity. This reduction in stress resulted even when participants did not take advantage of this opportunity. Implications for job performance and job satisfaction are discussed. Organizational strategies for how leaders can help employees manage social interruptions are suggested.     

Performance During a 3-Hour Simulated Sentry Duty Task Under Varied Work Rates and Secondary Task Demands

The performance of 14 soldiers was evaluated during 3 hr of simulated sentry duty when (a) the primary work rate was varied and (b) participants were required to intermittently perform a simple secondary task. Performance measurements included latency to detect a target, number of correct target detections, correct friend versus foe identification, targets hit, and latency to respond to the presentation of a continuous tone (secondary task). Activity monitors measured motor activity during study participation. During higher work rate sessions, participants responded to the appearance of a target more quickly, discriminated friend from foe more accurately, and hit more foe targets. The addition of a simple auditory task to the primary task did not affect performance on any of the sentry duty measures. These findings demonstrated that moderate increases in task engagement, or work rate, improved most performance metrics on a long duration (3-hr), militarily relevant vigilance task.     

The Predictive Stability of Ability Requirements for Task Performance: A Critical Renalysis

The traditional tenet of the stability of measured ability requirements for task performance has been challenged by a changing-abilities-requirements view. This view, based largely on interpretations of Fleishman's research, holds that systematic changes in the abilities contributing to performance occur relative to a variety of criterion tasks, as practice on those tasks continues. Previous criticisms of Fleishman's experimental-factor analytic approach are summarized and extended in this article. A reanalysis of %4 pairs of rs reported in Fleishman's studies and in a replication study by Hinrichs showed that the incidence of significant change in rs was within the range of chance expectation. Factor analytic studies by Fleishman and others that do not support the changing-abilities-requirements view are reviewed. The practical implications of Fleishman's research are discussed. It is argued that the data cited in support of the changing-abilities-requirements view require examination of external validity beyond laboratory practice tasks. Judgment on the issue of the stability of ability requirements should be withheld until more appropriate studies are conducted.     

Plasma Catecholamine and Performance Associations During Psychological Stress: Evidence for Peripheral Noradrenergic Involvement With an Attention-Demanding Task

The purpose of this investigation was to examine the associations between plasma catecholaminc (CA) response and selected performance measures during psychological stress. Nineteen men (between the ages of 35 and 50) performed a double-conflict (DC) task for 12 min. Self-reported distress resulting from the stress protocol was assessed using the Profile of Mood States and the Spielberger State-Trait Anxiety Inventory. Performance of the DC task was measured by total reaction time (TRT). Cognitive aftereffects were assessed by the time it took to complete three sets of anagrams administered immediately after the DC task. Plasma CA measures were taken at three intervals during the rest period and the DC task. The stress protocol resulted in increased self-reported tension, p ≤ 0.01; confusion, p ≤ 0.01; and anxiety, p ≤ 0.01; with reduced vigor, p less than or equal to 0.01. The men displayed improved TRT, p less than or equal to 0.01, during the DC task, and they had significantly extended performance time, p less than or equal to 0.01, on anagram Set 1 compared to Sets 2 and 3. Although both plasma norepinephrine (NE) and plasma epinephrine (E) increased, only E achieved statistical significance, p less than or equal to 0.05. The only significant correlation between plasma CA and performance occurred with NE and anagram Set 1, p less than or equal to 0.05. The findings arc discussed in terms of a postulated link between circulating NE and cognitive effects of stress.     

Musical Training,Bilingualism, and Executive Function: A Closer Look at Task Switching and Dual‐Task Performance

This study investigated whether musical training and bilingualism are associated with enhancements in specific components of executive function, namely, task switching and dual‐task performance. Participants (n = 153) belonging to one of four groups (monolingual musician, bilingual musician, bilingual non‐musician, or monolingual non‐musician) were matched on age and socioeconomic status and administered task switching and dual‐task paradigms. Results demonstrated reduced global and local switch costs in musicians compared with non‐musicians, suggesting that musical training can contribute to increased efficiency in the ability to shift flexibly between mental sets. On dual‐task performance, musicians also outperformed non‐musicians. There was neither a cognitive advantage for bilinguals relative to monolinguals, nor an interaction between music and language to suggest additive effects of both types of experience. These findings demonstrate that long‐term musical training is associated with improvements in task switching and dual‐task performance.

LMX and Subordinate Performance: The Moderating Effects of Task Characteristics

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.     

The Effects of Self-Set Goals on Task Performance

Locke & Latham (1990a) report that specific, difficult goals lead to better performance than "do-your-best" instructions, whether the goals are self-set or are set by an external source. However, in Experiment I, as well as in previous research (White, Kjelgaard, & Harkins, 1995), we did not find self-set goal effects. A meta-analysis showed that self-set goal effects can be produced if two conditions are met: Prior to setting their goals, participants take part in a pretest that is equal in duration to the experimental task; and the experimenter has access to the participants' goals and the performances. Experiment 2 confirmed these meta-analytic findings by showing that when these two conditions were met, goals stringent enough to produce the effects were set, and goal-setting effects were obtained.     

A Sensemaking Approach to Ethics Training for Scientists: Preliminary Evidence of Training Effectiveness

In recent years, we have seen a new concern with ethics training for research and development professionals. Although ethics training has become more common, the effectiveness of the training being provided is open to question. In the present effort, a new ethics training course was developed that stresses the importance of the strategies people apply to make sense of ethical problems. The effectiveness of this training was assessed in a sample of 59 doctoral students working in the biological and social sciences using a pre–post design with follow-up and a series of ethical decision-making measures serving as the outcome variable. Results showed not only that this training led to sizable gains in ethical decision making but also that these gains were maintained over time. The implications of these findings for ethics training in the sciences are discussed.     

不同形式的语言介入对汉语儿童心理理论发展的干预

为比较语言本身和语言交流的情境过程对儿童心理理论的贡献以及欺骗在此过程中的作用,本研究采用前后测对照实验设计探查了不同形式的语言介入和相关欺骗训练对儿童心理理论发展的影响。选取语言能力达到常模水平但未通过外表－事实区分任务的4岁组儿童77名,随机分为3个训练组和1个对照组,对其进行心理理论和语言能力前测,在各组的两种能力发展水平相当的前提下,对3个训练组分别作如下处理：完全训练组：带有心理状态动词的补语句法及欺骗训练;情境交际组：伴随语言情境交际训练和欺骗训练;补语句法组：心理状态动词和补语句法训练。一周后进行心理理论后测。结果表明,3个训练组与对照组之间在心理理论表现上均有显著差异。相对于一般语言交流的情境过程,补语句法和心理状态动词更能显著提高儿童的心理理论;早期欺骗经历也能促进儿童心理理论的发展,若二者结合使用则更利于儿童心理理论的改进     

The Effects of Task Content and Reward Contingency Upon Task Performance and Satisfaction1

A laboratory study examined the effects of task design and reward contingency upon task performance and satisfaction and upon behavioral and attributional measures of intrinsic and extrinsic motivation. Intrinsic and extrinsic motivation were defined by the task content-task consequence distinction. Both the task design and reward contingency factors were found to yield significant multivariate F ratios, but their interaction was not significant. Subjects in the contingent pay condition had higher performance quantity than those in the noncontingent condition. Subjects in the enriched task condition produced higher quality units than those in the nonenriched condition. Both contingent pay and enriched task conditons yielded higher task satisfaction and increased attributions of performance to intrinsic factors. Results were discussed in terms of cognitive evaluation theory and the distinction between intrinsic and extrinsic motivation.     

The Effectiveness of a REBT Training Program in Increasing the Performance of High School Students in Mathematics

The efficacy of an REBT-based skill training program on the mathematics performance of disadvantaged black eleventh graders enrolled in Upward Bound was examined. Fifty-six students (18 males and 37 females) were randomly assigned to Perception Analysis Training (PAT) or an attention control group (ACG). The two groups met at the same hour each week for eight-weeks. PAT consisted of instruction in the application of RET strategies to the management of emotions that interfere with the development of proficiency in mathematics. ACG group members discussed films pertaining to career and personal development. Pre-test results confirmed a relationship between beliefs and mathematics achievement. Three measures of problematic beliefs concerning mathematics were significantly correlated (p>.01) with high school math grades and performance on the California Achievement Test-Math (CAT). At post-test PAT participants were less committed to self-defeating beliefs regarding mathematics than AGC members. ANCOVAs showed that PAT students made significantly greater pre- to post-test gains in their mathematical performance than control group members. PAT group members out performed AGC subjects in terms of Upward Bound math grades (ES=0.61; p >.0008), high school math grades (ES = 1.09; p>.0001), and scores on the CAT (ES=0.40; p >.02).     

Cohesiveness and Performance on an Additive Task: Evidence for Multidimensionality

Abstract

This experiment contrasted two predictions regarding the effects of two types of cohesiveness on the performance of American students. Task-based cohesion and interpersonal cohesion were manipulated independently. Results show that high task cohesion facilitated performance, whereas interpersonal attraction had no apparent effect on production. Increases in interpersonal cohesion did, however, result in higher task commitment and more frequent interactions among group members. A path analysis suggested that potentially beneficial effects on production of increasing task commitment were obviated by the increased conversation also resulting from interpersonal cohesion. These data suggest that cohesiveness should be conceptualized as a multidimensional rather than as a unitary variable.     

The Effect of Crowding on Human Task Performance1

In a series of three experiments, groups of people performed tasks under varying conditions of density. The tasks ranged from very simple to complex, from rote memory to a test of creativity. Subjects worked on the tasks for 4 hours at a time for two or three successive days. There were no significant effects of density on performance, nor any consistent trends.     

The Effect of Attitude Similarity on Task Performance1

It was hypothesized in a two-person situation that students would perform significantly better on intellectual tasks when paired with a liked other than when paired with a disliked other. In a laboratory experiment, 108 male undergraduates performed one of three types of intellectual tasks with an attitudinally similar or dissimilar partner or with a partner about whom the subject had no attitude information. Individuals paired with a similar partner felt affectively more positive than those paired with a dissimilar partner (p < .01). Individuals paired with a similar other performed significantly better on the tasks than those paired with a dissimilar partner (p < .01).
