Human operant behavior is often said to be controlled by different variables or governed by different processes than nonhuman operant behavior. Support for this claim within the operant literature comes from data suggesting that human behavior is often insensitive to schedules of reinforcement to which nonhuman behavior has been sensitive. The data that evoke the use of the terms sensitivity and insensitivity, however, result from both between-species and within-subject comparisons. We argue that because sensitivity is synonymous with experimental control, conclusions about sensitivity are best demonstrated through within-subject comparisons. Further, we argue that even when sensitivity is assessed using within-subject comparisons of performance on different schedules of reinforcement, procedural differences between studies of different species may affect schedule performance in important ways. We extend this argument to age differences as well. We conclude that differences across populations are an occasion for more precise experimental analyses and that it is premature to conclude that human behavior is controlled by different processes than nonhuman behavior. 相似文献

Compared widowed spouses who joined (n = 40) bereavement support groups (BSGs) during the first 13 months of bereavement with those who declined to join (n = 96). Controlling for gender, age, and socioeconomic status, no differences were found for perceived levels of social support, but joiners, compared with nonjoiners, reported experiencing more stressful events and scored significantly higher on measures of depression, anger, anxiety, and subjective stress. Nonjoiners and, to a lesser extent, joiners viewed those attending groups as less self-sufficient (e.g., need help, lonely), suggesting a mildly stigmatizing image of BSGs. A dialectical model is proposed in which BSG utilization rates are seen as the product of an avoidance-avoidance conflict involving the choice between suffering emotional distress on one's own or the perceived stigma of joining a BSG. Implications for future research on participation in self-help and mutual support groups are discussed. 相似文献

Recent interest in the characteristics of effective managers raises the notion that personality factors may be part of the effectiveness syndrome. Modern research in personality systematics makes it possible to refine and extend earlier analyses of this topic. A job analysis of three levels of management in a large trucking company identified the personality characteristics of good managers, as described by peers and subordinates. These managers and a large group of incumbents (n=372) completed the Hogan Personality Inventory (HPI). Managers were assigned scores reflecting their status in the organization; they also were rated by their supervisors. A subset of HPI components were significantly associated with the criteria, with correlations ranging from .22 to .66. These components were combined and used in five separate validity studies. The resulting measure was significantly associated with managerial performance in a variety of organizational settings. These results are consistent with the growing body of evidence suggesting that a coherent set of noncognitive characteristics promotes managerial performance across organizational types. 相似文献

Relationships among life events, prosocial skills, and behavior problems for 91 first through fourth grade children were examined. The data were based on mothers' reports of their children's lifetime life events, current prosocial skills, and current behavior problems. Higher prosocial skills scores significantly predicted lower Externalizing behavior problem scores. Higher weighted life events scores significantly predicted higher Internalizing behavior problem scores. The weighted life event scores×prosocial skills scores interaction did not significantly predict either Externalizing or Internalizing behavior problem scores. The more parsimonious main effects conceptualization suggests that life events and prosocial skills are orthogonal in young, elementary school children. 相似文献

Claims Examiners are critical for the profitability of large insurance companies. Mistakes in hiring these people can result in improperly processed claims and/or turnover, and this yields negative financial consequences for the company. This paper describes research evaluating the validity of selection procedures for the position of claims examiner at Blue Cross and Blue Shield of Oklahoma. A job analysis indicated that both cognitive skills and personal abilities are necessary for successful performance as a claims examiner. The job analysis also indicated that both subjective and objective criterion measures reflect important aspects of job performance. The criterion data included nine supervisory ratings, employee nominations, average percent of performance, absences, disciplinary actions, and sick leave. In a concurrent validation strategy, we tested a sample of experienced incumbents (N=50) using four cognitive ability tests (Basic Skills Tests: BST) and two measures of personality (Hogan Personality Inventory and PROFILE). Scales from two personality inventories were combined to form the Claims Examiner Inventory (CEI). Scores from the CEI and three of the four cognitive tests correlated significantly with the average percent of performance and six of the supervisory ratings, including the average supervisory rating. In addition to the cognitive measures, the personality measure contributed significantly to the prediction of percent of performance achieved with R=.64. These results are consistent with other research findings that support the use of both personality and cognitive measures as predictors of job performance. 相似文献

A number of studies manipulating the length of the interval between conditioning and testing indicate spontaneous recovery from overshadowing, suggesting that certain instances of overshadowing represent a deficit in memory retrieval rather than a failure of animals to form an association between the overshadowed stimulus and the US. The present series of experiments examined the influence of lengthening the retention interval on blocking, another stimulus selection phenomenon that is typically interpreted as an acquisition deficit. The results indicated that when subjects were tested shortly (3 days) after training conditioning to a taste blocked subsequent conditioning to an odor conditioned in compound with that taste (Experiment 1), whereas prior conditioning to an odor did not block subsequent conditioning to a taste conditioned in compound with that odor (Experiment 2). This pattern of results was essentially unchanged when testing occurred at a longer (21-day) retention interval. However, there was evidence of a US preexposure effect in Experiment 2 when subjects in the US ONLY control condition were tested at the 3-day retention interval, but not when testing occurred 21 days after conditioning. Experiments 3 and 4 examined whether this loss of the US preexposure effect over time might actually represent a change in the degree of contextual blocking as the retention interval is lengthened. Exposure to the conditioning context either during the interval between Phase 1 and Phase 2 of conditioning (Experiment 3) or prior to Phase 1 of conditioning (Experiment 4) alleviated this US preexposure effect suggesting that the loss of the US preexposure effect as the retention interval is lengthened observed in Experiment 2 is due to changes in the degree of blocking by contextual stimuli over time. The results are discussed in terms of differential susceptibility of forgetting of two functional roles played by a contextual stimuli in the current situation-context as a CS and context as a retrieval cue for other CS-US associations. 相似文献

At present there is a “crisis” in psychology in South Africa. A mental health investigation has been initiated and a national task force appointed in order to reform the profession in all its aspects. These events are the result of a deep sense of unease about the mission, relevance and image of the profession and an awareness that mainstream psychology is irrelevant to the nature and needs of the majority black population. Presently psychology in South Africa is at a crossroads. This paper identifies the mental health needs of the majority black population and suggests professional training programmes for future psychologists and the utilisation of services and resources in delivery systems. The article also re-defines the psychologist's role in a divided and traumatised society. 相似文献
