Two cynomolgous macaques categorized six colors into two groups of three after conditional discrimination training (zero-delay symbolic match-to-sample). The procedures resulted in the establishment of relations among the elements of each set-relations that were not specifically trained and that can be characterized by the properties of reflexivity, symmetry, and transitivity. Each set of colors was related to a characteristic pattern of responding: One response pattern involved temporal duration (press and hold the response keys); the second response pattern entailed repeated pressing and releasing of the response keys (fixed ratio 8). Six combinations of two colors were trained, three combinations from each set. After discriminative performance stabilized for each monkey, they were tested with 10 additional color combinations, all of which differed from the training combinations. The conditional relations established between test combinations can be characterized as stimulus equivalence. The training procedures were analogous to the procedure of using category names, and have implications for understanding the function of language in the formation of equivalence classes. 相似文献

All seven variables of containment theory were operationalized for questionnaires. Data were collected from 677 adolescents in a variety of high schools and correctional institutions, and divided into categories by race and sex. Factor analysis indicated that the structure of the relationships among the seven containment variables and delinquency was substantially different among black females. 相似文献

It is suggested that molar streams of behavior are constructed of various arrangements of three elementary constituents (elicited, evoked, and emitted response classes). An eight-cell taxonomy is elaborated as a framework for analyzing and synthesizing complex behavioral repertoires based on these functional units. It is proposed that the local force binding functional units into a smoothly articulated kinetic sequence arises from temporally arranged relative response probability relationships. Behavioral integration is thought to reflect the joint influence of the organism's hierarchy of relative response probabilities, fluctuating biological states, and the arrangement of environmental and behavioral events in time. 相似文献

Recently a controversy has arisen among behavioral decision theory researchers concerning the generalizability of research based upon student subject samples to the behavior of expert decision makers. This study compared the influence of framing and performance constraints (goals or limits) on the ability of expert and amateur negotiators to reach integrative agreements in a negotiation task novel to both. The results suggested that while experts did outperform amateurs on comparable competitive market simulations, the patterns of their performance as influenced by framing and performance constraints were consistent. 相似文献

Newcombe, Bandura, and Taylor developed a questionnaire measuring participation in space-related activities. The activities were classified as masculine, feminine, or neutral in gender stereotyping. A short version of this questionnaire was developed based on an item analysis of the responses by 485 introductory psychology students (236 women and 249 men). The 10 masculine, 10 feminine, and 10 neutral items chosen for the short form were given to 60 subjects (28 women and 32 men), along with a measure of spatial performance (Piaget's water-level task). Reliabilities (by coefficient alpha) were .79, .77, and .75, for the masculine, feminine, and neutral activity subscales, respectively. As with the original scale, women had a greater preference than men for feminine activities, men had a greater preference than women for masculine activities, and women and men had an equal preference for neutral activities. Masculine activity preference was associated with better water-level performance, with the relationship significantly stronger for women (r=.50) than for men (r=.10). Uses for the questionnaire in research on sex-related differences in spatial performance are suggested. 相似文献

This study assessed the role of adaptive versus maladaptive coping behaviors and personal characteristics in influencing the affective reactions of managers to four role stressors. Maladaptive coping was found to moderate the relationships of several role stressors with felt stress and job satisfaction. Maladaptive coping and trait anxiety also demonstrated independent additive effects on felt stress and job satisfaction over and above that of all four stressors. 相似文献
