Two experiments were performed for the purpose of isolating factors that influence speed of memory scanning by children. The first experiment revealed an interaction involving age and type of stimulus. Young children required relatively greater time to process ambiguous stimuli. The second experiment, involving a pretraining phase designed to induce mediation, showed that preschool children scan representations more rapidly when given instructions to apply a mediator. 相似文献

Stimulus-echo latencies of a blind, severely echolalic child were measured to assess the capabilities of spontaneous transduction/reproduction of a verbal signal. Mean offset-to-onset latencies of 270 msec and onset-to-onset latencies of 792 msec are comparable to laboratory reaction times for syllable imitation. Results are considered within the theoretical context of physiological speech, i.e., externalized exposure of a psittacine level of verbal processing divorced from semantic, syntactic, lexical and, quite probably, phonological interference. 相似文献

How infants come to master reaching for moving objects was studied in a situation where the distance to and the velocity of the moving object varied. Eleven infants participated in the study. They were from 12 to 24 weeks old at the first session, were seen at 3-week intervals until 30 weeks old, and were finally seen once at 36 weeks old. The following behaviors were observed from video recordings: frequency of fixated and followed motions, latency to first goal-directed behavior, type of goal-directed behaviors, and type of reaches. It was found that by the time the infant masters reaching for stationary objects he will also successfully reach for moving ones. Eighteen-week-old infants caught the object as it moved at 30 cm/sec. The results suggest a basic human capacity to time-coordinate one's behavior with external events, and to foresee in one's actions future positions of moving objects. 相似文献

Rats of the Maudsley Reactive and Maudsley Non-reactive strains were given 25 trials of escape-avoidance conditioning after exposure to inescapable shock. Prior shock exposure (PSE) did not affect avoidance or escape latencies, but decreased the number of avoidances made by the Maudsley non-reactive animals and increased the number of their failures to escape. The results are interpreted as demonstrating an interference with the classical conditioning of a conditioned emotional response, through a reduction in the information content of the CS following PSE. The strain differences are interpreted as due to the non-reactive animals being especially sensitive to PSE. 相似文献

Walster, Walster, Piliavin, and Schmidt (Journal of Personality and Social Psychology, 1973, 26, 113–121) found that a hard-to-get woman was liked only if she was hard-to-get for other men but easy-to-get for the subject. They suggested that the subjects liked this type of woman because of the socially desirable personality characteristics they attributed to her. A second determinant of liking is proposed in the present study. It concerns the effect of a person's evaluation of a subject on the subject's self-esteem. It was predicted that there would be a positive relationship between changes in the subject's self-esteem and liking for the evaluator. The results demonstrated that this determinant, as well as the one that Walster et al. suggested, is important in understanding the type of opposite-sex person that men and women find most attractive. These results, and the differences between the Walster et al. and the present studies, were discussed in terms of the relative impact of the two determinants in laboratory and real-life situations. 相似文献

Career commitment processes in the young adult years: An illustration from the ROTC/Army career path
Josefina Jayme Card 《Journal of Vocational Behavior》1978,12(1):53-75
This paper presents and tests a model of career commitment in the young adult years. Data for the study were collected from nationwide stratified random samples of approximately 1000 high school seniors, 1600 college students, and 600 ROTC-graduate Army officers. It was found that the model could predict membership in ROTC and the strength of the individual's commitment to a military career and that hypotheses that had been made about the career commitment process were generally confirmed. Many of the specific findings, differences in the demographic, aptitude, and sociopsychological profile of participants and nonparticipants in a career path, the widening of these differences with the passage of time, the importance of early exposure to the career eventually chosen, the relationship between initial motivation in exploring a career path and subsequent commitment to the career, and the changes in the nature of influential factors as an individual matures, may be generalizable to other types of careers. 相似文献

In a natural setting, helping was investigated as a function of a female requestor's dependency on the subject for help and whether or not she was at fault for her plight. Based on previous research and the hypothesized operation of two norms, it was predicted that the negligent requestor would be more likely to receive help than the victim of circumstance when her dependency was high, but would be less likely to receive help when her dependency was low. Randomly selected telephone subscribers received a “wrong number” telephone call from a stranded women motorist. The woman asked the subject to make a phone call for her; the dependent variable was whether the subject helped by making the call. Results were consistent with predictions. When dependency is high, the victim's negligence appears to operate as an indication of greater need, whereas when dependency is low, it seems to operate as a sign that the victim is less deserving of help. Results were discussed in relation to different social norms that may be activated as a function of the dependency of the requestor. 相似文献

There seems to be widespread agreement among theoreticians and methodologists alike that new approaches to studying intelligence should somehow combine the differential and cognitive (information-processing) approaches that have been used in the past, and that the combination should somehow enable the investigator to isolate components of intelligence that are elementary (at some level of analysis). Researchers disagree, however, as to how the differential and cognitive approaches should be combined, and consequently, in how elementary components of intelligence should be isolated and in what they are. How does an investigator choose from among the multiple paths available for theory and research? In this article, I propose some guidelines that may help investigators make informed choices. The article is divided into three major parts. In the first, I propose guidelines for choosing from among various methodologies for studying intelligence, and then describe briefly at least some of the methods that meet (or come close to meeting) these guidelines. In the second part, I propose guidelines for the specification of subtheories (and eventually, full-fledged theories) of intelligence, and illustrate how these guidelines can be met. Finally, I describe the direction in which I believe our subtheories and methods should lead us. 相似文献

A series of studies investigated the conditions under which normal and educable mentally retarded adolescents (13 to 15 years old) would or would not disregard irrelevant information in memory. A directed forgetting task was used in which the person was required to recall short sequences of picture names. In some sequences there was a cue to forget the first few pictures (irrelevant information) and to remember only the subsequent pictures (relevant information). When normal adolescents were given no explanation of the forget cue, there was interference from the irrelevant information. A minimum explanation of the cue, however, was sufficient to eliminate interference for the normal adolescents. The same minimal explanation was not sufficient for mentally retarded adolescents. It was clear that irrelevant information in memory interfered with the performance of retarded adolescents given only a minimal explanation of the forget cue. These results are important since most naturalistic situations do not involve an elaborate explanation of the importance of disregarding irrelevant information previously stored in memory. 相似文献

Three studies are reported, which tested the notion that persons possessing the Type A “coronary-prone” behavior pattern would be more susceptible to the experience of psychological reactance than would Type Bs, i.e., persons without that pattern. In Experiment 1, subjects exposed to a persuasive communication that was either low or high in coerciveness rated the degree of coercive intent behind the communication. Type As perceived greater coerciveness overall than Type Bs, a finding that was most reliable in the low coercion condition. In Experiment 2, subjects' postcommunication opinions were assessed, so that resistance to persuasion could be measured. A gender difference within Pattern A emerged from this study. Male Type As resisted the persuasion attempt to an equivalent degree whether it was low or high in coerciveness; female Type As displayed comparable resistance in the low coercion condition, but tended to be even more resistant in the high coercion condition. In contrast, both male and female Type Bs displayed persuasion in the low coercion condition, and resisted (to a degree comparable to Type As) in the high coercion condition. Experiment 3 further investigated resistance to persuasion among females, using a different issue for the persuasion attempt. Type A women again resisted more in the high coercion than the low coercion condition. Type B women displayed no evidence of resistance in either condition. Discussion centers on the observed gender difference and the possible theoretical importance of the notion that Type As perceive threat at lower objective levels than do Type Bs. 相似文献
