28 dextral males participated in a within-subjects experiment which tasted for the effects of question type (verbal versus spatial) and experimenter-position (in front of or behind the subject) on direction of conjugate lateral eye movements (LEMs) and bilateral differences in skin conductance responses (SCRs). Question dependent asymmetries were observed for LEM direction but not for SCR magnitude. Experimenter-position had no significant effect. The results for LEM direction are consistent with the hypothesis linking eye movements to the left or right with activation of the cerebral hemisphere contralateral to the direction of gaze. The results for SCR magnitude, given certain assumptions, can be reconciled with a hemispheric model of contralateral excitatory control of that system. 相似文献

This study examined the relationship of traditionality of occupational preferences and sex-role orientation to personality-occupational environment congruence in college women. Three-letter Holland personality codes were obtained for each of 184 college women based on same-sex normative scores from the Strong-Campbell Interest Inventory and on scores from the ACT Unisex Interest Inventory (UNIACT). Subjects' occupational preferences were classified as traditional, moderately traditional, or nontraditional based on the percentages of women in the occupation. Scores on the Bern Sex Role Inventory were used to classify subjects into one of four sex-role categories. Results indicated a strong association between congruence and traditionality of choice; women whose choices were in nontraditional career fields were significantly more likely to be making choices congruent with their personality type than were women choosing traditional career fields. Further, while sex-role orientation was not significantly related to either congruence or traditionality, masculine-typed women were most likely to make nontraditional and congruent career choices, while the majority of feminine-typed, androgynous, and undifferentiated women stated preferences for traditional career fields. Implications for the applicability of Holland's congruence postulate to women's vocational behavior are discussed. 相似文献

Two experiments concerned with children's intentional preparation for future retrieval in a memory-for-location task are presented. In the first experiment, 3-, 5-, 7-, and 9-year-olds were instructed to store and subsequently retrieve an object on a large spatial display. All age groups, except the 3-year-olds, tended to store the object at distinctive locations and their retrieval performance was facilitated accordingly. The four age groups did not differ in the types of selections made in a nonmemory control task. The second experiment dealt with the effects of feedback and informational factors on strategy acquisition. Preschoolers were given experience at retrieving the object from distinctive and nondistinctive positions on the stimulus display. Later, when instructed to store the object by themselves, older preschoolers produced the distinctive-position storage strategy following a feedback procedure in which they directly observed the consequences of their retrieval selections. The strategy was adopted by younger preschoolers, but only when additional strategy and task information accompanied visual feedback. The use of external memory tasks with young children and factors affecting strategy acquisition and utilization are discussed. 相似文献

Three experiments are reported which investigate the effects of attentional factors on learning set performance of children. Number of varying irrelevant dimensions, trials per problem, and age were examined. The first experiment tests with 6- and 8-year-old-children the effects of one as opposed to two varying irrelevant dimensions. An interaction between age and dimensions showed younger children to be differentially affected by the treatment conditions, two varying irrelevant dimensions being more difficult than one. There was no difference between treatments for the older children, nor between older and younger subjects receiving one varying irrelevant dimension. In the second experiment, 6- and 8-year-olds were examined on two varying irrelevant dimension problems, receiving either 4 or 12 trials per problem. Amount of exposure within-problems, affected performance with 12 trials per problem resulting in superior performance at both age levels. A third experiment tested 6-, 8-, and 10-year-old-children using one and two varying irrelevant dimension problems with 4 and 12 trials per problem. Results confirmed the finding that learning set acquisition is influenced by irrelevant dimensions and within-problems exposure, with these effects interacting with age and amount of training. These findings support the utility of applications of an attentional analysis to the learning set performance of normal children. 相似文献

The present investigation sought to test the applicability of the excitation transfer model (P. Tannenbaum & D. Zillmann. In L. Berkowitz, Ed., Advances in experimental social psychology, Vol. 8, New York: Academic Press 1975) to prosocial behavior. This model predicts that for individuals predisposed to act prosocially, arousal transferred from an unrelated source will facilitate such behavior. Two studies were conducted in which male college students, treated in either a positive or neutral manner and shown an arousing erotic or nonarousing control film, ostensibly rewarded and punished a confederate for performance on a memory task. Contrary to predictions, the first experiment found the arousing film increased reward regardless of treatment. In the second experiment, where the neutral treatment was given a more negative tone, the predicted interaction was found. Specifically, subjects treated in a positive manner and shown an arousing film were significantly more rewarding than were similarly treated subjects shown the nonarousing film. While type of film had no effect on neutral subjects' reward behavior, the arousing film did increase their punitive behavior. These results, coupled with physiological and self-report data, strongly support the excitation transfer model. 相似文献

Let n be the class of all finite interval orders that can be interval-represented using no more than n interval lengths or threshold levels. Thus 1 is the class of finite semiorders, and , the union of the n, is the class of finite interval orders. While each of 1 and is axiomatizable by a universal sentence in first-order logic, no n for is axiomatizable in the same sense. 相似文献

A series of experiments was carried out to evaluate the notion that rats given a sequence of massed daily trials on the radial maze reset working memory at the end of each trial by deleting its contents. Although curves presented by D. S. Olton [Scientific American, 1977, 236, 82–98; In S. H. Hulse, H. Fowler, & W. K. Honig (Eds.), Cognitive processes in animal behavior, Hillsdale, N.J.: Erlbaum, 1978] show that rats return to errorless performance at the beginning of each trial after the first, the fact that accuracy falls less rapidly over choices on Trial 1 than on subsequent trials suggests a proactive inhibition (PI) effect. In Experiment 1, Olton's findings were replicated, and a PI effect was observed on Days 1–2 of testing. On Days 3–5, overall accuracy improved significantly and was associated with the development of a strong tendency for rats to enter adjacent alleys, which became particularly marked on the final trials of a day's testing. In order to prevent rats from achieving accurate performance by using an adjacent alleys pattern, a procedure was used in Experiment 2 which involved initial forced random choices followed by a retention test consisting of free choices. Repeated daily trials with this procedure yielded a significant PI effect, which was more marked at a 60-sec delay than at a 0-sec delay. Experiments 3 and 4 showed this PI effect to be robust and resistant to manipulations designed to produce release from PI. Both the PI effect and a strong tendency found in Experiment 1 for animals to avoid on the initial choices of Trial n those alleys most recently entered on Trial n?1 argue that rats do not reset working memory between trials. 相似文献

Groups of adolescents of retarded and borderline intelligence, ranging in IQ from 44 to 80 and in mean MA (mental age) from 8 to 12 yr, and groups of nonretarded children ranging in mean MA from 6 to 12 yr, were given logical problem solving tasks. In the nonretarded groups, on a one-bit problem only the kindergarten children (mean MA = 6 yr) failed to perform above chance, and were not tested further. On a two-bit problem, only the first graders (mean MA = 7 yr) failed to perform above chance.Conversely, in the low IQ groups, only the borderline group (mean MA = 12 yr) performed reliably above chance on the one-bit problem, and none performed above chance on the two-bit problem. There is a profound deficiency in low IQ individuals on certain tasks requiring logic and foresight, and MA markedly over-estimates their performance relative to the performance of nonretarded individuals. 相似文献

The literature concerning the controversy between dissonance and selfperception theories is reviewed. It is proposed that the two theories be regarded not as “competing” formulations but as complementary ones and, furthermore, that each theory is applicable only to its own specialized domain. Self-perception theory, it is suggested, accurately characterizes attitude change phenomena in the context of attitude-congruent behavior and dissonance theory attitude change in the context of attitude-discrepant behavior. Attitude-congruent is defined as any position within an individual's latitude of acceptance; attitude-discrepant as any position in the latitude of rejection. An experimental test of these notions produced confirming evidence. Subjects who were given an opportunity to misattribute any potential dissonance arousal to an external stimulus did not change their attitudes, relative to low choice subjects, if they were committed to endorsing a position in their latitude of rejection. If the commitment concerned a position in the latitude of acceptance, however, these subjects did exhibit attitude change relative to low choice subjects. 相似文献
