Perception in chess 总被引:2,自引:0,他引:2
This paper develops a technique for isolating and studying the perceptual structures that chess players perceive. Three chess players of varying strength — from master to novice — were confronted with two tasks: (1) A perception task, where the player reproduces a chess position in plain view, and (2) de Groot's (1965) short-term recall task, where the player reproduces a chess position after viewing it for 5 sec. The successive glances at the position in the perceptual task and long pauses in the memory task were used to segment the structures in the reconstruction protocol. The size and nature of these structures were then analyzed as a function of chess skill. 相似文献

This study examined whether dissonance is, phenomenologically, an aversive state. Experimental subjects were induced to write counterattitudinal essays under a high-choice condition. One group of subjects was led to believe that a pill, which they had just taken in the context of a separate experiment, would cause them to feel pleasantly excited. A second group was led to believe that the pill would make them feel tense. A third group was given no information about the pill's potential side effects, while a fourth group expected to have no side effects at all. In this last condition, the results yielded the usual dissonance effect: subjects stated attitudes more congruent with the essay than did subjects in a survey control condition. When subjects were given an opportunity to attribute their arousal to an arousing, but nonaversive pill (i.e., the pleasant excitement condition), this effect was unchanged. In contrast, when subjects could attribute their arousal to an aversive pill (i.e., in the tensè and the no information conditions), this effect was virtually eliminated. These results are consistent with the notion that dissonance is an aversive state and that subjects will seize, when possible, an external attribution for this state. 相似文献

A series of three experiments is described comparing an aversive imagery and an electrical escape conditioning procedure in the treatment of chronic alcoholics. Treatment effects were objectively measured by recording subjects' alcohol consumption in a semi-naturalistic laboratory setting. In contrast to conventional group outcome studies, the use of single-subject methodology provided a fine-grained analysis of individual response patterns. The aversive imagery and escape conditioning methods did not differ from each other, and were relatively ineffective in suppressing alcohol intake. In contrast, a punishment procedure in which shock was contingent on drinking did effectively suppress drinking. The data suggest that alcoholics can control their drinking by self-administered shock. The implications for the analysis and treatment of alcoholics are discussed. 相似文献

The characteristics of mediational mechanisms based upon magnitude of reinforcement were investigated using rats. In two experiments, two-choice discriminations were trained in which selections of one lever in one external stimulus and a second lever in another external stimulus were reinforced with food. In the first experiment, it was found that the discrimination was acquired more rapidly when one choice was reinforced with a large number of food pellets and the other with a smaller number of pellets than when other configurations of reinforcement magnitude were provided. In the second experiment, reversal of a two-choice discrimination was found to be facilitated by prior exposure of the animals to the reversed relationships between the external stimuli and magnitudes of reinforcement. These results were consistent with predictions from a stimulus or associative view of anticipatory processes based upon magnitude of reinforcement. 相似文献

Rats with a history of intermittent punishment have been found to persist in the face of continuous punishment. It was predicted from an extension of frustration theory to punishment that increasing the intensity or frequency of intermittent punishment would increase persistence to high fear elicited by continuous punishment. Two experiments, employing 310 rats, verified this prediction for both intensity and frequency manipulations but indicated rather narrow boundary conditions for their effects. 相似文献

Two studies are reported which test the hypothesis that extraverts are more tolerant of cognitive inconsistency than are introverts. The first study tested this prediction in the context of Heider's balance model. While degree of extraversion did not moderate reactions to imbalance, extraverts did show less aversion to interpersonal disagreement than introverts. When coupled with other recently published data this suggests that extraverts find arousing social situations less aversive than introverts. In support of the main hypothesis, the second experiment showed that extraverts changed their attitudes less than introverts as a result of writing an essay which was counter to their own attitude under conditions where they had high perceived freedom of choice. 相似文献

A cross-validation methodology was employed to identify 16PF scales and items that significantly correlated with performance on the verbal, spatial, and memory/numerical abilities measured by the WAIS in a nonpsychiatric sample of 489 adults. For both men and women larger personality-ability correlations resulted in all analyses for verbal ability than for spatial or memory/numerical ability. The 16PF scale analysis offered results generally consistent with Cattell's research. The item analyses produced rather similar results for both sexes for verbal and spatial abilities. For verbal ability three major correlates resulted: communicative competence, equanimity/low anxiety, and a desire for times alone. Though few in number the item correlates of spatial ability suggested a dispassionate, nontemperamental style of interaction with one's environment as the major correlate. Memory/ numerical ability was somewhat independent of 16PF item responses for women, but was associated with fastidiousness in men. Possible cause-effect relationships were suggested and implications for future research discussed. 相似文献
