In three experiments rats were given injections of LiCl after consuming distinctively flavoured water. The rats developed an aversion to the flavour and in all experiments the magnitude of the aversion was found to be reduced in subjects that had received pre-exposure to the flavour without aversive consequences. Experiment 1 demonstrated this pre-exposure effect to be a case of latent inhibition. The remaining experiments investigated the effects of pre-exposing the flavour in a context different from that used for conditioning. It was found (Experiment 2) diat latent inhibition transferred perfectly when the context change consisted of a move from one home cage to another. Context specificity of latent inhibition was found (Experiment 3) only when the subjects were given daily sessions in die experimental contexts, these being cages different from the home cage. 相似文献

In two experiments involving a total of 542 subjects, a series of slides depicting a burglary was shown. After the initial event, subjects were exposed to one or more narratives about the event that contained some misinformation or neutral information about four critical details. Finally, subjects were tested on their memories of what they saw, and their reaction times and confidence levels were measured. When subjects took a standard test in which the misinformation item was a possible response option, they responded very quickly and confidently when making this incorrect choice. Misled subjects responded as quickly and confidently to these "unreal" memories as they did to their genuine memories. It does not seem, then, that the misinformation effect arises from a large proportion of subjects who must resolve a conflict between two memories when they are tested, a conflict that would be expected to take time. When subjects took a modified test in which the misinformation item was not a possible response, misled subjects were as accurate as were controls, but they responded more slowly, regardless of whether they ultimately chose the right or wrong option. These findings indicate that misinformation does introduce some form of interference not detected by a simple test of accuracy. 相似文献

How much is an icon worth? 总被引:1,自引:0,他引:1

We report a new technique for assessing the amount of information extracted from the icon that follows a briefly presented picture. The problem of how to measure such information was formulated in terms of how much physical exposure of a picture an icon is worth. Consider two types of stimulus presentations, each with a base duration of d ms. The first is a d-ms picture followed by an icon, and the second is a d + a-ms picture not followed by an icon. How large does a have to be so that equivalent amounts of information are extracted in the two cases? To answer this question, we showed people pictures and later tested their memory for the pictures. We found that the physical exposure duration needed to reach a particular level of performance was approximately 100 ms longer when an icon was not permitted versus when the icon was permitted. This value was independent of the base duration and the luminance of the picture. Moreover, the same value was obtained using three different kinds of memory test and four different sets of pictures. We conclude that an icon is worth approximately 100 ms of additional physical exposure duration. A reasonable explanation for this robust equivalence between icon and stimulus is that the same encoding processes are responsible for extracting information from the icon and from the physical stimulus. Therefore, any variable that affects these encoding processes must affect extraction of information from the icon and the physical stimulus in an identical manner. This prediction was confirmed for one such variable, picture luminance. 相似文献

From an initial pool of 96 students, 36 subjects were selected based on Novaco Anger Scale scores to form high-, moderate-, and low-anger groups (n=12). They completed self-report questionnaires and participated in a structured interview designed to elicit cognitive and affective responses to hypothetical situations involving interpersonal conflict. High- and moderate-anger groups scored significantly higher than low-anger subjects on a questionnaire measure of irrational thinking. High-anger subjects scored higher than low-anger subjects on general anxiety, suspiciousness, fear of negative evaluation, hostility, and criticism of themselves and others. Interview ratings showed that there were no group differences in self-reports of anger or ability to cope with conflict, yet raters judged high-anger subjects to display more anger than low-anger subjects in their stated response actions. Estimates of coping ability varied inversely with reports of anger experienced. Generally, results support a relationship between irrational thinking patterns and anger in feeling and action. Implications for treatment are discussed. 相似文献

In three experiments, 469 subjects watched a short videotape of a bank robbery and later estimated the duration of the tape. Subjects invariably overestimated the durations. Accuracy of time estimation was unrelated to amount of free recall (Experiment 1) or accuracy of memory (Experiment 2). Females overestimated to a greater degree than males (Experiments 2 and 3). A more stressful version of the event produced greater overestimates than a less stressful version (Experiment 3). The relationship between induced arousal and time estimation appears to be different for men and women. 相似文献

When people are exposed to misleading details after a witnessed event, they often claim that they saw the misleading details as part of the event. We refer to this as themisinformation effect. In four experiments, involving 570 subjects, we explored the role that discrepancy detection plays in the misinformation effect. Experiment 1 showed that subjects who naturally read a post-event narrative more slowly were more resistant to the effects of misleading information contained in the narrative. In Experiment 2, subjects who naturally read more slowly were more likely to detect a discrepancy between what they were reading and what was stored in their memory. In Experiment 3, subjects who were instructed to read slowly were more likely to detect a discrepancy than were those who were instructed to read quickly. In Experiment 4, subjects who were instructed to read slowly were more resistant to misleading postevent information. Taken together, these results suggest that longer reading times are associated with a greater scrutiny of postevent information. This leads to an increased likelihood that discrepancies will be detected and that the misinformation will be resisted. 相似文献

There are very few women who take up careers as engineers - especially at the non-professional level. The present research attempts to throw some light on this issue, examining by means of a postal questionnaire the educational experiences of 22 young women craft and technician apprentices in a variety of engineering jobs. Comparisons are made with 33 similar young women who have chosen more traditional 'female' occupations. The results show significant differences between engineers and non-engineers in terms of their subject choices and curriculum opportunities at school and their perceptions of the attitudes of parents to wards their careers. Possible implications of the findings for developments in curriculum planning and careers guidance are explored. 相似文献

The paper attempts to account for the confusion over the validity of the concept of schizophrenia in terms of two closely related aspects of conceptual indeterminacy. Firstly, it is identified on the basis of a breakdown in intelligibility, but what constitutes such a breakdown is indeterminate. Secondly, the concept sits between the categories of natural disease or illness on the one hand, and character trait or moral failing or gift on the other. This entails an indeterminacy in attempting to define the role that physiological explanation could have. Light may be thrown on the concept by exploring a distinction between a life story in which the schizophrenic condition emerges as the conclusion of the story and a causal process in which the condition is the end result or final consequence. 相似文献
