Four groups of pigeons were trained on a free operant successive discrimination between line-stimuli differing in orientation. The groups differed according to their previous treatment. Two groups had received true discrimination (TD) training with stimuli differing in colour and two groups had received pseudo-discrimination (PD) training. For one pair of groups the line-stimulus that was to become the positive stimulus in the transfer stage of the experiment was superimposed on both colours and in these the subjects given PD training learned the orientation discrimination more readily than those given TD training. In the other pair of groups TD animals learned more readily than PD. These results require us to modify current theories of attentional factors in transfer. 相似文献

College students high and low in test anxiety attributed their performance on each of four examinations in a course to ability, test difficulty, preparation, and luck. Individuals high and low in test anxiety typically evidence systematic predispositions to account for their achievement-related behavior in different terms. The present research substantially replicated these earlier (laboratory and Intellectual Achievement Responsibility Scale) findings in an actual achievement setting. In addition, however, the present findings differed from the earlier evidence in some important respects. Specifically, (a) high test-anxiety students' attributions for failure were far less self-deprecating than in the laboratory evidence, and (b) high test-anxiety students' attributions (for both success and failure) became more personally flattering, or comforting, as the semester progressed. Results were discussed in terms of the laboratory — field distinction and of the influence of a temporal, or time of measurement, factor, hitherto ignored in the causal attribution literature.This research was facilitated by a grant from the Research Council of the Graduate School, University of Missouri-Columbia, and the National Institute of Mental Health (1 R08 31910), both to the first author. 相似文献

This study investigates the expression of attitudes by individuals within the context of groups. A link is made between two
theoretical areas: that of intergroup relations and that of the effects of group interaction on the expression of opinions.
It is argued that individuals in groups adopt more polarized attitudes to achieve a more positively distinct group identity,
and to afford themselves identification with that group. Subjects individually expressed their opinion on an issue, while
the salience of group membership was varied by evoking the identity of an alternative group which held opposed opinions on
the issue. When their own group identity was more salient, subjects tended to express their opinions in a more polarized manner,
and in a manner more in keeping with the presumed view of their group. Also, they attributed to the other group attitudes
that were more polarized and more in keeping with their presumed view of the issue. 相似文献

Subjects viewed sequences of slides depicting everyday events, and in later recognition tests, they correctly rejected distractors that were inconsistent with some invariant of the event but falsely accepted consistent distractors. J. J. Jenkins has accounted for the differential recognition of consistent and inconsistent slides of pictorial sequences in terms of fusion, the abstraction of an event from a series of temporally related items. The conditions under which event fusion was likely to occur were manipulated in three experiments: degree of ordering of the action-sequence slides, semantic vs. nonsemantic orienting tasks during acquisition, and duration of retention interval Recognition performance was generally more accurate under conditions of semantic processing, ordered acquisition sequences (for the semantic task), and shorter retention intervals. However, these variables did not affect differential recognition of consistent vs. inconsistent slides. A further experiment showed that the absence of an effect of disordering acquisition sequences on differential recognition could not be attributed to subjects’ reordering the disordered sequences in a way consistent with the original event. The data did not support the hypothesis that recognition performance was based on fusion of events depicted by temporally ordered slide sequences. It was suggested that memory for featural detail is a relevant factor in performance. 相似文献

When people recall an event collaboratively we may expect the product to be influenced by the combined cognitive resources of the group, interpersonal acquaintance of the members, and social competition engendered by salient intergroup considerations. Using undergraduate students and serving police officers as subjects, a range of experimental conditions was established which varied on the three factors of cognitive resources of the participants (Cognitive Resources), interpersonal acquaintance of the participants (Interpersonal Acquaintance) and professional salience (Professional Salience) of the recall material. Participants answered a questionnaire concerning a police interrogation they had witnessed, and rated how much confidence they had in their answers. Multiple regression revealed statistically significant associations between (i) Cognitive Resources and number of correct answers, (ii) Interpersonal Acquaintance and confidence for implicational errors, and (iii) Professional Salience and (a) number of implicational errors and (b) confidence in confusional errors. The theoretical implications for our understanding of memory as a social process are discussed, and the practical implications for courtroom testimony briefly described. 相似文献

When measuring the same variables on different occasions, two procedures for canonical analysis with stationary compositing weights are developed. The first, SUMCOV, maximizes the sum of the covariances of the canonical variates subject to norming constraints. The second, COLLIN, maximizes the largest root of the covariances of the canonical variates subject to norming constraints. A characterization theorem establishes a model building approach. Both methods are extended to allow for Cohort Sequential Designs. Finally a numerical illustration utilizing Nesselroade and Baltes data is presented.The authors wish to thank John Nesselroade for permitting us to use the data whose analysis we present. 相似文献

College students in two psychology courses estimated their confidence in passing and their anticipated score for three examinations. On the first examination the results from both courses supported the prediction that women, compared to men, would be less confident of passing, would predict lower scores, and would underestimate their obtained scores. These sex differences disappeared, as predicted, on the second and third examination for the course, in which the situation remained relatively constant over the term. However, contrary to predictions, the sex differences were maintained over all three examinations for the second course, which involved different instructors for each exam. Thus, the effects of feedback on performance expectancies seem to be vulnerable to situational changes. 相似文献
