Previous research has implicated time urgency as a component of coronary-prone behavior. Arguments of Type A persons often suggest that their time-urgent stylistics are necessary to guarantee success, particularly in complex and/or managerial tasks. Experimentally induced time urgency was utilized in a simulated complex managerial task with unselected subjects to test the validity of such an assumption. It was found that time urgency interacts with information load to produce performance outcome. Moderately complex planning and decision making was found to be optimal at intermediate load levels, but disintegrated when time urgency increased to high levels. Similar results were obtained for long-term complex planning. Retaliatory decision making increased with load. Higher levels of time urgency resulted in greater retaliatory activity. It is concluded that managerial activities that require complex decision making and long-term future planning are hindered rather than aided by time urgency.  相似文献

This study integrates research linking academic performance with individual differences and class attendance. Whereas individual differences (ability, traits) are not controllable by students, students can control their attendance, study and work. Thus we sought to determine the extent to which “control” and “no control” variables predict academic performance. With N = 338, measures of verbal ability, the five-factor model, GPA, academic goals, and study behavior were used to predict exams, attendance, and independent projects completed. Uncontrollable factors accounted for 37% of the variance in exam scores; controllable factors accounted for an additional 6–10%. We also found an interaction such that, relative to low-ability peers, high-ability students’ attendance most enhanced their exam performance. Attendance was best accounted for by GPA, study and work. Projects were best predicted by low verbal ability and by personality traits.  相似文献

Using longitudinal data from a Chinese newcomer sample (N = 671), we investigated the predictive effects of adaptability on newcomers’ work‐related outcomes. Specifically, we tested 4 perceived P–E fit variables (i.e., P–O fit, needs–supplies fit, demands–abilities fit, and P–G fit) as mediators between adaptability variables and newcomers’ work‐related outcomes. Our results showed that after controlling for demographic effects and other personality variables (i.e., proactive personality and openness to experience), newcomers’ adaptability dimensions (i.e., cultural adaptability, work stress adaptability, interpersonal adaptability, and learning adaptability) were differentially associated with improvement in newcomers’ P–E fit perceptions over a 3‐month time period. In turn, the perceived P–E fit variables were related to the newcomers’ work‐related outcomes (i.e., job performance, job satisfaction, and turnover intentions), after controlling for the socialization process variables (i.e., institutionalized socialization experience, role clarity, and job‐related self‐efficacy). The mediating roles of perceived P–E fit variables were also confirmed. Both theoretical and practical implications in terms of adaptability, newcomer adaptation processes, and P‐E fit are discussed.  相似文献

Background. Current theories of self‐regulated learning predict a positive link between student monitoring accuracy and performance: students who more accurately monitor their knowledge of a particular set of materials are expected to more effectively regulate their subsequent study of those materials, which in turn should lead to higher test performance. Aims. The present study further explored the link between monitoring accuracy and performance by investigating whether monitoring of one set of materials would predict performance on a different set of materials. Sample. The participants were college students (N= 379) enrolled in an educational psychology course. Method. Students’ monitoring accuracy was measured at the start of the semester; the monitoring task involved materials that were not related to class content (i.e., general knowledge vocabulary) and that were related to class content (i.e., terms from educational psychology). Target performance was students’ scores on the final exam. Results. Monitoring accuracy significantly predicted student performance on the final exam, even when the monitoring task and final test were based on materials from different content domains. Also, the class‐related (vs. unrelated) materials in the monitoring task did not improve the predictive validity of monitoring accuracy, suggesting a limited role for domain specificity in the relationship between monitoring skill and performance. Conclusions. This study establishes a critical link between general monitoring accuracy and exam performance within a classroom setting.  相似文献

This study compared attentional strategies in prioritized and unprioritized multitasking situations using individual differences in the Type A behavior pattern (TABP) as predictors. The study expanded previous studies by using a triple task situation that presented two visual tasks and one auditory task simultaneously. One hundred and eighteen undergraduate students were utilized. One group received instructions for all tasks and their relative importance to each other for achieving a full performance score. The other group received instructions for the visual tasks only, and no information about their relative importance was given, creating ambiguity about priorities among the tasks. Global TABP and its subcomponents (i.e., time urgency, achievement strivings, impatience or irritability, polychronicity) were utilized as predictors of task performance. Significant correlations were found between the TABP subcomponents and different performance indexes, but such a relation was not found between global TABP and performance. Applied implications of these findings and directions for the future research are discussed.  相似文献

Fred E. Fiedler made an important contribution in summarising and discussing the tricky relationships between test-intelligence, time in service, and perceived experience on the one side, and rated leadership performance on the other. Two strings of results seem to be of importance for improving our knowledge on these relationships: (1) test-intelligence correlates with rated performance especially in the case of low perceived stress, and experience especially in the case of high stress; (2) test-intelligence correlates with rated performance if the other resource, perceived experience, is low. Both strings of results may fit with our expectations. Nevertheless, some aspects of the problem might trouble some readers, for reasons that Fiedler is not responsible for. There seem to be at least three clusters of unfulfilled wishes within this topic of research: selection and operationalisation of variables; design; and task requirements and intelligence.  相似文献

Studies have replicated both negative and positive associations between helpless attributional style and academic performance. Laboratory studies indicate that when enhancement effects occur, they may be moderated by the degree of failure individuals experience prior to task performance. In a longitudinal study of 96 college students who completed four examinations in two introductory psychology courses, we examined the relationship between helpless attributional style and examination performance across the semester, and whether prior examination failure moderated this association. Correlational analyses revealed that helpless attributional style was unrelated to exam performance in the first half of the semester and was positively related to improvements in performance in the second half. Regression analyses indicated that these enhancement effects were not moderated by previous performance on examinations in the course. The present findings underscore the need for longitudinal studies that investigate the pattern of associations between helpless attributional style and performance across time in real-life contexts.  相似文献

Two experiments were conducted to examine behavioral consequences of a sense of time urgency, which presumably characterizes individuals classified as manifesting a so-called “Type A” coronary-prone behavior pattern. Experiment I indicated that time-urgent Type A Ss were reliably less successful than noncoronary-prone “Type Bs” in performing a task requiring a low rate of response for reinforcement (DRL). Type As were not only unable to delay their responses; they also showed greater evidence of tension and hyperactivity than Type Bs during DRL performance. Experiment II extended these results to the interpersonal domain. Time-urgent Ss became more impatient and irritated than less urgent Ss when both types were systematically slowed down in their efforts to reach a solution on a joint decision-making task. The results were discussed in terms of a conceptualization of the A-B dimension as reflecting differential expectations of and needs for environmental control. Additional evidence was presented in support of this approach. Consideration was also given to possible physiologic mechanisms mediating the relationship between psychological variables such as the Type A pattern and actual occurrence of coronary heart disease.  相似文献

External number representations are commonly used throughout the first years of instruction. The twenty-frame is a grid that contains two rows of 10 dots each, and within each row, dots are organized in two groups of five. The assumption is that children can make use of these structures for enumerating the dots, rather than relying on one-by-one counting. We compared first-grade children's performance on two types of computerized enumeration tasks, in which between one and 20 dots were presented in random arrangements or on a twenty-frame. The number of dots was a strong predictor of response times and accuracy rates in the enumeration task with random arrangements but not in the twenty-frame task. Performance on the twenty-frame task was correlated with performance on a number and arithmetic test, even when other cognitive variables were statistically controlled. We discuss these findings in the light of theories on utilizing external representations to support numerical learning.  相似文献

Personality processes relating to social perception have been shown to play a significant role in the experience of stress. In 5 studies, the authors demonstrate that early stage attentional processes influence the perception of social threat and modify the human stress response. The authors first show that cortisol release in response to a stressful situation correlates with selective attention toward social threat. Second, the authors show in 2 laboratory studies that this attentional pattern, most evident among individuals with low self-esteem, can be modified with a repetitive training task. Next, in a field study, students trained to modify their attentional pattern to reduce vigilance for social threat showed lower self-reported stress related to their final exam. In a final field study with telemarketers, the attentional training task led to increased self-esteem, decreased cortisol and perceived stress responses, higher confidence, and greater work performance. Taken together, these results demonstrate the impact of antecedent-focused strategies on the late-stage consequences of social stress.  相似文献

ABSTRACT

Exposure to negative life stress has been associated with difficulty retrieving memories for specific autobiographical events, with important consequences for the emergence of emotional disorders. We examined whether social support can protect against the effects of negative events on memory specificity. University students (N?=?143) were assigned to groups based on whether or not they experienced a negative stressor, operationalised as whether or not their recent exam performance was in line with their expectations. After receiving their exam results (T1), and one month later (T2), participants completed measures of memory specificity, their attitudes towards themselves and the occurrence of other stress-related events. Participants also completed a general measure of perceived social support from friends, family, and significant others, and an equivalent measure for social support related to performance. For participants who experienced an exam-related stressor, reduced performance-specific social support from friends was associated with reduced memory specificity at T2, even when accounting for T1 memory specificity, individual differences in attitudes towards self, the experience of additional stressors, and gender. No such relation was present for participants who did not experience a stressor. These findings provide new understanding of the influence of social variables on autobiographical memory specificity.  相似文献

The study examined the effects of degree of paramenstrual distress, signal frequency, task load and time on task on psychomotor performance across the menstrual cycle. Simple reaction time, choice reaction time and pursuit tracking were the tasks employed, and performance was assessed using the metrics of mean level, variability, and errors of omission and commission. The results showed performance as a function of menstrual cycle phase and paramenstrual distress to be highly task and metric specific, a finding typical of stressor variables: pursuit tracking was affected by phase, with mean performance at its worst premenstrually; choice reaction time was dependent on a complex interaction of experimental variables and measurement metrics; simple reaction time showed no significant effects. Patterns of attention allocation in a time-sharing situation combining both pursuit tracking and choice reaction time components were also investigated. Trends here indicated relatively better performance both menstrually and intermenstrually as components increased in signal/response frequency, with a corresponding deterioration premenstrually. Overall performance capacity appeared to be greatest at menstruation, and the degree of attentional selectivity was least. High distress women performed better on low frequency components, whereas asymptomatic women did better at higher signal rates.  相似文献

The main purpose of this experiment was to examine the independent and interactive effects of three variables—attentional demand, cue typicality, and priming—on an event‐based prospective memory task. High attentional demand was expected to lower performance, but cue typicality and priming were expected to improve performance. The prospective memory task entailed writing an ‘X’ after hearing items from four semantic categories (e.g. birds), while performing a free‐association task. Results showed the predicted effects of attentional demand and typicality. Priming did not affect overall prospective memory performance but, as predicted, improved performance under conditions of high attentional demand with a typical cue. Overall, these results show the importance of cue and capacity variables, but they also support the value of examining how different variables in the prospective memory task can interact in affecting performance.

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.  相似文献

We examined the basic question of whether pressure is stressful. We proposed that when examining the role of stress or pressure in cognitive performance, it is important to consider the type of pressure, the stress response, and the aspect of cognition assessed. In Experiment 1, outcome pressure was not experienced as stressful but did lead to impaired performance on a rule-based (RB) category-learning task, but not on a more procedural information-integration (II) task. In Experiment 2, the addition of monitoring pressure resulted in a modest stress response to combined pressure and impairment on both tasks. Across experiments, higher stress appraisals were associated with decreased performance on the RB, but not on the II, task. In turn, higher stress reactivity (i.e., heart rate) was associated with enhanced performance on the II, but not on the RB, task. This work represents an initial step toward integrating the stress cognition and pressure cognition literatures and suggests that integrating these fields may require consideration of the type of pressure, the stress response, and the cognitive system mediating performance.  相似文献

Do interindividual differences in prospective memory task performance reflect individual differences in personality and lifestyle? Do the cognitive abilities known to change with age retain their power to predict episodic prospective memory task performance after controlling for personality and lifestyle variables, and do personality and lifestyle variables offer predictive power apart from that provided by cognitive ability measures? To answer these questions, we conducted a study with community‐living healthy individuals (n= 141) between 18 and 81 years of age. They completed three different episodic prospective memory tasks – two laboratory tasks and one field task – as well as various measures of personality, lifestyle, and cognitive ability. The results indicated that personality and lifestyle reliably predicted who will succeed and who will fail on all three episodic prospective memory tasks. Conscientiousness predicted performance on two of the prospective memory tasks; socially prescribed perfectionism and neuroticism each predicted performance on one of the prospective memory tasks. Cognitive ability predicted performance on one of the laboratory prospective memory tasks but not on the other two prospective memory tasks. After we controlled for individual differences in personality and lifestyle variables, cognitive ability was no longer able to predict performance on the laboratory prospective memory task. By contrast, controlling for cognitive ability had no influence on the predictive power of the personality and lifestyle variables.  相似文献

Research on stress has generally concluded that stress occurs within the person as a result of their cognitive appraisal of experience. However although a number of cognitive theories of emotion exist, an integrative analysis of cognitive appraisal and vulnerability to stress has not been produced. This report contains two studies. Study 1 draws together the major variables identified in the literature in an analysis of their power to differentiate between a clinical sample (n = 48), a self-help group (n = 54), and a control sample (n = 509). The analysis shows that achievement motivation, attributional style, problem-solving style, emotional reactivity; hopelessness, perceived control and perceived social support are significant discriminators. In a second study the relationship between these variables and aspects of life stress, work stress, life satisfaction, depression, anxiety, and positive affect were investigated. Again the data support an explanatory role for these variables. The suggestion is that these variables can be utilized in an integrative model of cognitive appraisal in the stress process to guide intervention.  相似文献

Prospective memory is memory for the realization of delayed intention. Researchers distinguish 2 kinds of prospective memory: event- and time-based (G. O. Einstein & M. A. McDaniel, 1990). Taking that distinction into account, the present authors explored participants' comparative performance under event- and time-based tasks. In an experimental study of 80 participants, the authors investigated the roles of cognitive load and task condition in prospective memory. Cognitive load (low vs. high) and task condition (event- vs. time-based task) were the independent variables. Accuracy in prospective memory was the dependent variable. Results showed significant differential effects under event- and time-based tasks. However, the effect of cognitive load was more detrimental in time-based prospective memory. Results also revealed that time monitoring is critical in successful performance of time estimation and so in time-based prospective memory. Similarly, participants' better performance on the event-based prospective memory task showed that they acted on the basis of environment cues. Event-based prospective memory was environmentally cued; time-based prospective memory required self-initiation.  相似文献

This study examined the relationship of operator personality (Five Factor Model) and characteristics of the task and of adaptive automation (reliability and adaptiveness-whether the automation was well-matched to changes in task demand) to operator performance, workload, stress, and coping. This represents the first investigation of how the Five Factors relate to human response to automation. One-hundred-sixty-one college students experienced either 75% or 95% reliable automation provided with task loads of either two or four displays to be monitored. The task required threat detection in a simulated uninhabited ground vehicle (UGV) task. Task demand exerted the strongest influence on outcome variables. Automation characteristics did not directly impact workload or stress, but effects did emerge in the context of trait-task interactions that varied as a function of the dimension of workload and stress. The pattern of relationships of traits to dependent variables was generally moderated by at least one task factor. Neuroticism was related to poorer performance in some conditions, and all five traits were associated with at least one measure of workload and stress. Neuroticism generally predicted increased workload and stress and the other traits predicted decreased levels of these states. However, in the case of the relation of Extraversion and Agreeableness to Worry, Frustration, and avoidant coping, the direction of effects varied across task conditions. The results support incorporation of individual differences into automation design by identifying the relevant person characteristics and using the information to determine what functions to automate and the form and level of automation.  相似文献

In this study, academic task assignments were modified in an effort to improve the conduct and task performance of three students with emotional and behavioral disorders. Functional assessments, including interviews and direct observations, were conducted to identify variables that affected the performance of each student during problematic assignments. The assessments implicated several variables for each student. These variables were then used as guides to modify the problematic tasks. The modifications resulted in reduced levels of problem behaviors and increased rates of task engagement, work productivity and accuracy for each of the students. The effects were demonstrated within ongoing academic activities and replicated through the use of reversal designs. The findings are discussed in relation to the practical process of functional assessment and the relevance of curricular and instructional arrangements to the occurrence of disruptive behavior.  相似文献
