In Experiments 1 and 2 rats were trained under two multiple schedules of reinforcement. In one, bar pressing during a tone-light compound stimulus was reinforced under a variable-interval food reinforcement schedule. In the other multiple schedule, bar pressing avoided grid shock on a free-operant schedule. In both multiple schedules, a discrimination was maintained by an extinction schedule that was operative during the absence of the tone-light compound. In Experiments 1 and 2 the intensity of the tone-light compound was manipulated over three levels. Subsequent extinction tests revealed that light was attended to, almost exclusively of the tone, when food reinforcement had maintained bar pressing. On the other hand, the tone gained considerable attentional control under the shock avoidance schedule. This stimulus-reinforcer interaction was maintained for all three levels of the compound intensity. In Experiment 3 it was investigated whether this interaction was associative by presenting shock during the absence of the tone-light compound when food reinforcement maintained responding, and food during the absence of the compound when shock avoidance maintained responding. Since both food and shock were presented during a single session for both schedules, nonassociative effects of the reinforcing stimuli were equivalent across the schedules. Nevertheless, the stimulus-reinforcer interaction was maintained, indicating that the interaction was an associative effect. 相似文献

The role of valence and instrumentality was examined in predicting three work-related criteria in a military setting: satisfaction, perceived effort, and turnover. A total of 323 enlisted men responded to desirability and instrumentality scales for each of four categories of performance outcomes: extrinsic rewards, personal fulfillment, recognition, and autonomy. Multiple regression analyses indicated that the different outcome types varied substantially in their relationship to the criteria, ranging from strongly positive to no relationship to strongly negative. Furthermore, the salience of valences and instrumentalities changed as a function of the criterion being predicted in a manner not deducible from current expectancy-valence models. Several implications of the results were discussed in terms of assumptions underlying general expectancy-valence approaches to motivation.This research was supported in part by Grant DAHC19-77-G0017 to New York University (Samuel Shiflett, principal investigator) from the Army Research Institute for the Behavioral and Social Sciences.

Adoption of a child is an event in which a number of crises have converged. Both the biologic and adoptive families have contributed their failures and crises, and the subsequent interpretations of these by the adopted child can lead to polarized themes of goodness and badness. The absence of the biologic parents and of a coherent history reinforces the tendency to splitting. This paper explores these operations and raises questions about prevailing adoption practices.Paper presented at Spence-Chapin Symposium on Identity Problems of Children in Non-Nuclear Families, April 11, 1981. 相似文献

The fading of a stabilized retinal image in the sighting and the nonsighting dominant eye was studied using the Haidinger’s brush target. Reaction time to the complete disappearance of the stabilized image was significantly longer when the target was input to the sighting eye. The greater persistence of stabilized targets in the sighting eye suggests possible differences in the neural channels from the two eyes or processing differences in the two monocular channels that are related behaviorally to eye dominance. 相似文献

A conceptual model of some of the intrapsychic and interpersonal forces that stimulate and maintain repetitive, nonproductive marital conflict behavior is presented. In this model, concepts derived from psychoanalytic and social-learning theory and integrated within a family systems framework. Implications for conjoint therapy with conflictual couples are discussed. 相似文献

Two studies were conducted to examine whether attributions made about events may be influenced by individual assumptions regarding causation that are age related. In Study 1, 96 subjects at three age levels (four and five years, eight and nine years, and college students) observed a target actor on videotape select an item from an unseen array, and four other actors either agree (high consensus) or disagree (low consensus) with the choice. Subjects were asked to decide why the actor liked the chosen object best—because of something about the actor (person attribution) or because of something about the item (entity attribution). The results showed that perceived locus of causality shifted from entity to person attributions with age. In addition, subjects at all ages were able to utilize the consensus information when they had no opportunity to form their own impressions about the items in the array. In Study 2, 126 subjects at four age levels (five and six years, seven and eight years, nine and ten years, and high school students) chose an item from among an array for themselves and responded to a person (self)/entity attribution question regarding the locus of their own choice. The entity to person shift with age was again found and was supported by additional measures. The results are discussed in terms of children's causal reasoning capacities and social environmental factors affecting developmental change in social judgments. 相似文献

Karttunen's seminal 1973 article Presuppositions of compound sentences, lays the groundwork for the elegant and fruitful theory of this subject which he subsequently presented in (1974). In (1973, pp. 185–8), however, he fallaciously argued that the regularities he discovered concerning the behavior of and, or, and if ... then in English cannot be embodied in any three-valued logic giving a truth-functional interpretation to these connectives. The present paper refutes Karttunen's argument by exhibiting an interpretation with the desired properties, and shows further how the full articulation of his 1974 system can be developed naturally within a truth-conditional semantics for English if bivalence is abandoned — contrary to what Karttunen expected. 相似文献

Some effects of positive life events on community mental health 总被引:1,自引:0,他引:1
Measures of positive and negative events were derived from a life-event inventory to test the predictions of an equilibrium model and a positive mental health model of psychological well-being. These measures were related to indicators of individual and community well-being with data obtained through a household survey of 454 residents. Residents who reported more negative events also reported more psychological distress and less positive adjustment. Positive events were associated with reports of positive adjustment. An analysis of census tract scores on life events revealed that the relative absence of positive events in census tracts was associated with higher service utilization rates to the community mental health center serving those tracts. The number of negative events was unrelated to service rates for census tracts but was related to several demographic indicators of well-being. 相似文献
