Three groups of pigeons were trained on a red-green discrimination in which the stimuli were alternately presented in a multiple schedule of reinforcement. The discrimination was reversed 24 times. Groups were given 1, 2, or 4 hr of training on each discrimination. Increasing the length of training had two principal effects on reversal performance: it increased the rate of extinction of responding to one of the stimuli and increased the rate of reacquisition of responding to the other. The latter effect involved both an increase in reacquisition of responding to a positive stimulus within reversals and an increase in recovery of responding to the previous negative stimulus between reversals. Improvements in performance of each group over the series of reversals were qualitatively similar to the two effects of length of training on each discrimination, and were analogous to effects obtained in other studies involving overtraining and successive reversals of simultaneous discriminations. 相似文献

On the basis of findings that categorical perception (CP) is possible in complex visual stimuli such as faces, the present study tested for CP on continua between unfamiliar face pairs. Results indicate that CP can be observed for unfamiliar faces, in both familiar (same-race) and unfamiliar (other-race) groups. In addition, significant CP effects were observed in inverted faces. Finally, half-continua were tested where midpoint stimuli became endpoints. This was done to ensure that stimulus artifacts did not account for the observed CP effects. Consistent with the perceptual rescaling associated with CP, half-continua showed a rescaled CP effect. We argue that these CP effects are based on the rapid acquisition of perceptual equivalence classes. 相似文献

To examine if animals could learn action-like categorizations in a manner similar to noun-based categories, eight pigeons were trained to categorize rates of object motion. Testing 40 different objects in a go/no-go discrimination, pigeons were first trained to discriminate between fast and slow rates of object rotation around their central y-axis. They easily learned this velocity discrimination and transferred it to novel objects and rates. This discrimination also transferred to novel types of motions including the other two axes of rotation and two new translations around the display. Comparable tests with rapid and slow changes in the objects' size, color, and shape failed to support comparable transfer. This difference in discrimination transfer between motion-based and property-based changes suggests the pigeons had learned motion concept rather than one based on change per se. The results provide evidence that pigeons can acquire an understanding of motion-based actions, at least with regard to the property of object velocity. This may be similar to our use of verbs and adverbs to categorize different classes of behavior or motion (e.g., walking, jogging, or running slow vs. fast). 相似文献

Assisting employees to explore internal job switches rather than leaving an organization is a positive measure aimed at enhancing employee retention and job satisfaction. This article describes how a municipal county government used J. L. Holland's (1992) occupational classification system to help employees achieve congruence between their interests and their job requirements. 相似文献

In Part I of this paper, we described a model that was used as a framework for reviewing studies of psychoeducational interventions intended to influence illness- and treatment-related behaviors and attitudes in pediatric cancer patients. In Part II, we distinguish between interventions that attempt to influence patients' behaviors just by providing information and interventions that specifically teach skills related to the behaviors they are trying to change. Many types of psychoeducational interventions appear to be effective and those that are training-based generally appear more effective than those that are information-based. Training-based interventions may face a barrier to wide adoption because they are resource-costly, but the development of digital-based training interventions may potentially overcome this barrier. 相似文献

Using multiple regression analysis and Pearson’s R, the current exploratory study of 89 African American male adolescents (M = 12.5 years old) examined relationships among REI (i.e., 20 as a socialization product of identity formation processes), prosocial behaviors (i.e., represented as supportive behavioral orientation in response to stress), and aggression (i.e., a reactive coping strategy). Significant relationships among racial public regard, age, and verbal aggression emerged. Older adolescents believed that other people have lower regard for their race, and this predicted an increase in verbal aggression. These findings demonstrate the importance of understanding contextual factors when examining outcomes. 相似文献

The objective of the study was to investigate whether high and low intensity versions of cognitive behaviour therapy (CBT) might be an effective therapeutic approach for enhancing the mental health of Aboriginal Australians. Five university‐educated Aboriginal counsellors received in‐depth training in CBT. Over the following year, they used CBT strategies with their clients, and met 10 times as a participatory action research group. The group addressed three key questions: (a) Does CBT appear to be useful for Aboriginal Australians? (b) If so, what elements of CBT are perceived to be effective? (c) What adaptations might be made to CBT to enhance its effectiveness with Aboriginal Australians? The resulting qualitative data were transcribed and analysed. Counsellors perceived CBT to be very useful for their Aboriginal clients and for themselves. They reported that it enhanced their clients' well‐being, their own clinical skills, and their own well‐being, and it reduced burnout. The qualities of CBT that were perceived to be effective were its adaptability, pragmatic here‐and‐now approach, capacity for low‐intensity interventions, safe containing structure, promotion of self‐agency, and valuable techniques. It was suggested that the prime requirement for adaptations to CBT were that they would need to fit different social and cultural contexts. 相似文献
