Two cognitive approaches, introduced by Schachter and Singer (1962) and by Valins (1966), have dominated the experimental study of emotion attributions. However, subsequent results using these approaches have not appeared to be very consistent, and this view is not consistent with more physiologically oriented theory. Research significant in the development of theory from these approaches was examined. Inconsistent findings using the Schachter and Singer paradigm were attributed to the difficulty of producting completely ambiguous physiological cues. The existence of active search in determining the cause of arousal was established and found central to production of Valins's false feedback effect. Postulated mediation by self-persuasion was found to provide the best fit to the existing data. The generality of these studies was described in terms of a more comprehensive theory based on the finding that the relative ambiguity of situational and physiological cues seems to provide the fundamental control over the emotion attribution process. This synthesis eliminates the deficiencies in previous hypotheses by more completely encompassing potential cue combinations.  相似文献

Learned helplessness theory predicts that animals exposed to inescapable shock acquire an expectancy of response-reinforcer independence, which proactively interferes with learning of response-reinforcer dependence. The theory also predicts that this expectancy can increase sensitivity to subsequent instances of response-reinforcer independence. These experiments test the latter prediction in a paradigm that minimizes the confounding effects of shock-induced activity deficits. Rats were trained to respond for food, then given either escapable, inescapable, or no shock. Subsequently, they received two sessions of response-contingent food followed by sessions of noncontingent food deliveries. During this phase, inescapably shocked animals decreased responding faster than did controls. Experiment 2 replicated this finding with a different schedule of food delivery and a procedure that more directly minimized the possibility that the outcome is due to either direct or indirect shock-induced activity changes. These results support the prediction that uncontrollable aversive events can increase an animal's sensitivity to noncontingent response-reinforcer relationships.  相似文献

The empirical base of Trope's position on achievement-task choice is critiqued here. Attention is focused on Trope's earliest studies (Trope, 1975; Trope & Brickman, 1975) because they provide this position's most critical tests. Support for the following three propositions of the position is assessed: (1) diagnosticity information, rather than task difficulty information, is the basis of task selection; (2) desire for information about one's ability, not the wish for certain affective consequences, is what motivates achievement-task choice; and (3) the success of the Atkinson model is owed to the adventitious confounding existing between task diagnosticity and task difficulty, and the resulting confounding between ability-informational and affective consequences. The major findings are that (1) the tests of all propositions have such serious logical flaws that they cannot answer the questions they seek to answer, (2) the task choice situation containing the diagnosticity manipulation employed by Trope is so different from real-life task choice situations as to call into question the relevance of Trope's findings for the latter situations, (3) Trope's diagnosticity manipulation is a meaningless one as it gives rise to situations that are logical impossibilities (e.g., skill tasks that are performed equally well by high- and low-skilled people), and (4) the tests of Atkinson's position are invalidated by a serious misinterpretation of that position by Trope.  相似文献

This paper describes how patients are interviewed in the context of a general hospital after they have been involved in an episode of self-harm. The interview schedule is structured upon the principles of brief therapy, and uses the 'neutral' approach of the Milan Team (Weakland 1974; Palazzoli et al. 1980). The schedule provides information for referring on and has proved to be 'therapeutic' in itself. The method of interviewing has been used in other hospital contexts with families where a member has been referred 'in a crisis' threatening, or indicating suicidal behaviour. It is suggested that the identification of who is involved systemically is of paramount importance, and that this may not involve 'the family' but significant others in the social network. The important systemic involvement of the general practitioner is recognized.  相似文献

The present study explored individual differences in performance of a geometric analogies task. Whereas past studies employed true/false or two-alternative items, the present research included four-alternative items and studied eye movements and confidence judgements for each item performance as well as latency and error. Item difficulty proved to be a function of an interaction between the number of response alternatives and the number of elements in items, especially for subjects lower in fluid-analytic reasoning ability. Results were interpreted using two hypothesized performance strategies: constructive matching and response elimination. The less efficient of these, response elimination, seemed to be used more by lower ability subjects on more difficult items. While two previous theories resemble one or the other of these strategies, neither alone seems to capture the complexity of adaptive problem solving. It appears that a comprehensive theory should incorporate strategy shifting as a function of item difficulty and subject ability.Componential models, based in part on past research, revealed that a justification component was activated and deactivated depending upon the nature of the analogy being solved. In addition, two new components, spatial inference and spatial application, were identified as important on some items, suggesting that different geometric analogy items invoke different cognitive processing components. Thus, a comprehensive theory should also describe component activation and deactivation.  相似文献

A battery of information processing measures and psychometric tests of specific and general cognitive abilities was administered to a sample of 105 individuals which included 34 monozygotic and 13 dizygotic reared apart twin pairs or triplets. Correlations between information processing parameters and psychometric abilities as well as twin resemblances for the information processing parameters were examined. In a principal components analysis of the information processing parameters, three components were identified which accounted for 67% of the total variation; Overall Speed of Response (OSR), Speed of Information Processing (SIP), and Speed of Spatial Processing (SSP). OSR was significantly correlated with WAIS IQ, and psychometric measures of verbal reasoning, spatial ability, and perceptual speed and accuracy. SIP was significantly correlated with WAIS IQ, measures of verbal reasoning, and one of the perceptual speed and accuracy measures. SSP was significantly correlated with measures of both spatial ability and perceptual speed and accuracy. Due to the small size of the dizygotic twin sample, no strong conclusions could be drawn regarding the magnitude of their resemblance. The correlation between component scores of reared apart monozygotic twins was significant for OSR, but not for SIP or SSP.  相似文献

Although the use of merit pay, incentive pay, bonus pay, and job promotion are well-established measures in the private or corporate sector of American society, few examples of successful teacher merit pay systems exist. In 1983, the Eastern Washington University Department of Education surveyed six major private corporations to determine whether corporate merit pay programs could be applied to teachers and educational institutions. Survey findings suggest several reasons why merit pay programs for teachers will probably fail: (a) lack of monetary goals; (b) the necessity for subjective evaluation, which requires multiple measurement devices, extensive supervision, and time; (c) the absence of a many-tiered corporate structure in most educational institutions; and (d) increased supervisory direction that could stifle creativity and flexibility.  相似文献

The influence of an isolated word’s meaning on lexical decision reaction time (RT) was demonstrated through four experiments. Subjects in two experiments made lexical decision judgments, those in a third experiment pronounced the words used in the lexical decision task, and those in a fourth experiment quickly pronounced their first associative response to the words. Differences in lexical access time for the words were measured with the pronunciation task, and differences in meaning were assessed with the association task. Multiple regression analyses of lexical decision RT were conducted using associative RT, pronunciation RT, and other target word properties (printed frequency, length, instance dominance, and number of dictionary meanings) as predictor variables. These analyses revealed a relationship between lexical decision RT and associative RT after the effects of other variables had been partialed out. In addition, word frequency continued to have a significant relationship to lexical decision RT beyond that shared with pronunciation RT and the other variables. The results of these experiments indicate that at least some of the effect of word meaning and word frequency in lexical decision is attributable to a decision stage following lexical access.  相似文献

Mixed hyperactive/reading-disabled children, selected from a large sample of hyperactive children, were compared to pure hyperactive children on demographic, behavioral, and neuropsychological measures. Children in the Mixed group were reading-disabled relative to age and IQ; those in the Pure group had achievement scores that were average relative to age and IQ. The Mixed group was significantly older than the Pure group; there were no differences in gender, race, or socioeconomic status. Behaviorally, the groups did not differ significantly on teacher ratings or on psychiatric ratings of aggression. The Mixed group had a significantly higher Performance IQ, whereas the Pure group had a significantly higher Verbal IQ and performed better on measures of cognitive impulsivity. Several other measures failed to distinguish the groups. The data give minimal support to the notion that pure hyperactive and mixed hyperative/reading-disabled children constitute distinct subgroups of Attention Deficit Disorder with Hyperactivity.This research was supported in part by Mental Health Clinical Research Grant MH-30906 and by U. S. Public Health Service Grant MH-18579.  相似文献
