Proactive interference was studied using an intratrial preparation in two delayed matching-to-sample experiments employing pigeons. On interference trials, an interfering sample and a target sample were presented successively and were followed by a test consisting of a choice between two stimuli, one associated with each sample. Control trials were identical to interference trials except that the interfering sample was not presented. On both types of trials, choice of the comparison corresponding to the target sample was defined as correct. Colored fields and line orientations were employed as sample stimuli in Experiment 1, and samples of food and no food and of number of pecks were employed in Experiment 2. Interference was found to be equally robust regardless of whether the interfering and target samples were each selected from any of the four dimensions (color, line orientation, food/no food, or number of pecks). Amount of interference was found to be independent of whether the interfering and target samples employed on a trial were selected from the same dimension or from different dimensions. Evidence was also obtained suggesting that line orientation comparison stimuli are more likely to elicit a response not based on memory than are color comparison stimuli. 相似文献

It was hypothesized that certain language style variations would reflect apprehension about affirming the validity of communication content. Wiener and Mehrabian (Language within language: Immediacy, a channel in verbal communication. New York: Appleton-Century-Crofts,1968) have identified a cluster of such variations called verbal nonimmediacy, which they describe as indicators of psychological distance between the communicator and his/her communication. Four experiments are reported. Experiments 1 and 2 showed that communication about positive manifestations of disliked traits and negative manifestations of liked traits was more nonimmediate than when positive manifestations of liked traits or negative manifestations of disliked traits were described. This was true both when one's own or another's personality traits were described. In Experiment 3, nonimmediacy was found to increase when communications involved clear fabrications about either one's liked or disliked traits. Experiment 4 showed that when self-regard was experimentally manipulated, low self-regard subjects showed more opinion conformity and nonimmediacy in their disclosures to a confederate than did high self-regard subjects. 相似文献

In a previous investigation, we demonstrated the role of questions as an instructional resource in the social construction of conversation by depriving conversationalists of their use. The resulting conversational structure, measured in terms of the ability of third parties to reconstruct the dialogues after they had been randomized, was impaired. The importance of culturally shared knowledge for the reconstruction (and by implication the construction) task was apparent in the superiority of British over Canadian subjects in reconstructing unconstrained British dialogues. The present study was concerned with the effects of privately shared knowledge on the construction of conversation. Conversational structure and the frequency of questions were greater in strangers' than in mutual acquaintances' unconstrained dialogues. Strangers' dialogues, but not those of mutual acquaintances, were disrupted under a ban on questions. The results were taken to indicate that strangers need to provide one another with continual instruction in how to proceed, whereas mutual acquaintances, in virtue of their privately shared social knowledge, can construct orderly dialogue with less moment-to-moment guidance. 相似文献

The purpose of the present research was to determine if forewarning subjects about the halo effect eliminated the effect or made people aware of its impact. The research was a replication and extension of R. E. Nisbett and T. D. Wilson's (Journal of Personality and Social Psychology, 1977, 35, 250–256) experiment on the halo effect. Subjects viewed an interview of a college instructor who was either warm or cold and then rated his physical appearance, mannerisms, and French accent. Some subjects were told to introspect about their cognitive processes while viewing the interview and were told that the purpose of the study was to see how aware they were of the determinants of their ratings. Other subjects were also told specifically what the halo effect was and given a motivation either to show it or not to show it. In addition, a measurement technique different from that used by Nisbett and Wilson was utilized to allow a more precise measurement of awareness, and a new cover story was used to make the task more involving and important to subjects. Despite these attempts to eliminate the halo effect (or, at a minimum, to make people aware of it), the results indicated that subjects in all conditions were very susceptible to it. That is, subjects who viewed the warm version of the interview rated the instructor's appearance, mannerisms, and accent significantly higher than did those who viewed the cold version, even when informed and forewarned about this effect. The forewarning and introspection instructions also had no impact on subject's awareness of the halo effect. Subjects in all conditions indicated that their liking for the instructor had had only a minimal effect on their ratings. 相似文献

Urban secondary school teachers participated in a cognitive-behavioral stress management program. Assessment data were also collected from a waiting list control group. Dependent measures included self-reported anxiety and stress, and observations of teacher classroom behavior. Results showed that the training program significantly decreased self-reported stress and anxiety. Follow-up data indicated further decrease six weeks after termination of the training program. Results also indicated decreases in motoric manifestations of anxiety in the classroom as a result of the training. 相似文献

Language disturbances were studied in 40 patients with well-demarcated vascular lesions of the speech-dominant hemisphere. Computerized cranial tomography was used for localization of the lesion. Special emphasis was given to the analysis of automatized speech and repetitive verbal phenomena.Subcortical infarctions with basal ganglia involvement led to transient aphasia although long-lasting abnormalities of language could be detected in these patients. Aphasia was more severe if a cortical lesion was combined with a basal ganglia lesion. Automatisms and recurring utterances occurred only with combined cortical and basal ganglia lesions. A lesion of Wernicke's area alone, without involvement of prerolandic structures or subcortical nuclei, was sufficient to produce long-lasting aphasia, whereas lesions of Broca's area alone produced only transient language disturbances. The results are compatible with a recent theory of multiple cerebral representation of function. 相似文献

The hypothesis that vulnerable self-esteem internals and externals would react more defensively to negative intellectual and personality feedback than congruent (more secure self-esteem) internals and externals was investigated in two experiments. The defensive (DE)-congruent (CE) external distinction was strongly confirmed in both cases. In Experiment 1, DEs assumed less personal responsibility for failure than for success, while CEs assumed little personal responsibility for either outcome. Defensive externals performed more poorly than CEs on a task described as an IQ test, suggesting greater anxiety in the face of possible failure. In Experiment 2, DEs rated themselves more favorably and derogated evaluator's competence more than CEs following receipt of negative information regarding their interpersonal skills. Congruent internals (CI) performed more poorly than defensive internals (DI) on the “IQ” task, while male DIs attributed responsibility for outcomes more defensively. It was suggested that a consistently internal view of causation may increase stress in evaluative situations. Implications of these findings for better understanding the relationship between locus of control and maladjustment were discussed, and suggestions for future research were presented. 相似文献

The left and right hemispheres perform different encoding and decoding operations on a syntactically complex sentence in order to identify its meaning. Hemispheric asymmetry for syntax involves not only variations in capacity, but also differences in the strategy used to effect similar language performance. 相似文献

EMR children were taught to produce an interrogative strategy as an aid to paired-associate learning. Interrogative training was spread over four sessions with experimenter guidance gradually faded; training was followed by tests of long-term retention for the trained items, strategy maintenance, and generalization. Metamemory was assessed prior to training and following generalization. Analysis of recall demonstrated successful maintenance and generalization of the interrogative strategy; the quality of elaborations produced by the trained children predicted recall accuracy. Importantly, metamemory pretest measures for the interrogative trained children were related to strategy use at generalization. Metamemory posttest reliably predicted recall during training, maintenance, and generalization sessions and strategy use at maintenance. Interrogative training did not noticeably improve general aspects of metamemorial knowledge. 相似文献

The category theory concept of a commutative diagram is used to construct a model of the way in which symbolic processes are applied to problem solving. The model provides for a relationship between symbolic processes and the problem which depends on structural isomorphism and consistency, but is independent of similarity between symbol elements and problem elements. It is then shown that several different levels of thought can be distinguished within the basic model. More information is needed to assign symbolic processes to a problem in a consistent way with higher-level thought processes than with lower-level processes. These information-processing requirements permit the approximate age of mastery of each level to be predicted, thereby offering an alternate theory of cognitive developmental stages. Two experiments designed to test the theory are reported. 相似文献
