In two experiments, 5- to 13-year-old children were required to mentally track the rotation of a pointer around a circular backdrop, and to indicate the pointer's imagined position on the backdrop at the sound of a signal. In Experiment 1, children imagined the pointer rotate around its end point. In Experiment 2, children imagined the pointer rotate around its midpoint, and indicated the position of one of its two ends at the time of the signal. The end to be indicated was not specified by the experimenter until the time of the signal. Thus, children were required to use an imaging strategy that could keep track of the changing positions of both ends of the pointer. In both experiments, children older than 8 years of age generated linear distance × time functions indicating mental tracking, but younger children did not. In Experiment 2, the proportions of children at each grade level using holistic or part-to-part strategies to mentally track the pointer were comparable, as were mental tracking rates. The results were discussed in relation to both recent research on children's counting, and Piagetian and information-processing views of metal imagery development. 相似文献

This paper reports a procedure, like classical conditioning, that produces enhancement of liking for flavors by humans. The procedure is “pairing” of a relatively neutral flavor with sugar (a hedonically positive taste). Specifically, subjects drank 24 small samples of flavor A sweetened and 24 small samples of flavor B unsweetened. They were then tested for their liking for flavors A and B, both sweetened and unsweetened. In three different studies, varying in a number of aspects of stimulus presentations and context, a relative enhancement in liking for flavor A appeared both on the day of exposure and 1 week later. An absolute enhancement in liking of flavor B (a “mere exposure” effect) also occurred in two of the three experiments. 相似文献

The present study compared two recent scales developed to measure career indecision, the Career Decision Scale and the Vocational Decision-Making Difficulty Scale. The subjects were 857 male and female undergraduates. The scales were factor analyzed, the total scores were correlated, and the factor structures were examined for similarities and differences. Test-retest correlations were performed on the items, the total scores, and the factor scores of both measures. Subjects who were satisfied with their career choices were compared with subjects who were unsure, dissatisfied, or undecided about their career choices using the items, total scores, and factor scores. The results are discussed along with the implications for the future development of the scales. 相似文献

The degree of agreement in independent diagnosis of headache by a neurologist and a clinical psychologist was determined to be 86.4% in a series of 66 consecutive patients. Fifty-five percent of the disagreements were due to the patients' giving different information to the two assessors. This source of disagreement was associated with the patients' having had previous psychiatric treatment.This research was supported in part by Grant NS-15235 from the National Institute of Neurological and Communicative Disorders and Stroke. 相似文献

The determinants of leadership seniority in laboratory groups were investigated in two experiments. In both experiments a procedure was used in which individual group members were periodically replaced throughout 7 generations. The individuals within the groups folded origami products and traded with other groups so as to earn quarters. In the first experiment the effect of social familiarity on seniority was investigated by comparing a set of standard groups with a set of rotational groups in which the group members moved from group to group between generations and thus always interacted with strangers. There was less seniority in the rotational groups. In the second experiment the effect of experience on seniority was investigated by comparing a set of standard groups with a set of experienced groups in which the new group members were recruited from the standard groups. There was less seniority in the experienced groups. It was found in both experiments, in agreement with previous research, that over generations the subjects earned increasing amounts of money and worked with increasing speed and efficiency. 相似文献

The role of sensory reinforcement was examined in programming multiple treatment gains in self-stimulation and spontaneous play for developmentally disabled children. Two phases were planned. First, we attempted to identify reinforcers maintaining self-stimulation. Sensory Extinction procedures were implemented in which auditory, proprioceptive, or visual sensory consequences of self-stimulatory behavior were systematically removed and reintroduced in a reversal design. When self-stimulation was decreased or eliminated as a result of removing one of these sensory consequences, the functional sensory consequence was designated as a child's preferred sensory reinforcer. In Phase 2, we assessed whether children would play selectively with toys producing the preferred kind of sensory stimulation. The results showed the following. (1) Self-stimulatory behavior was found to be maintained by sensory reinforcement. When the sensory reinforcer was removed, self-stimulation extinguished. (2) The sensory reinforcers identified for self-stimulatory behavior also served as reinforcers for new, appropriate toy play. (3) The multiple treatment gains observed appeared to be relatively durable in the absence of external reinforcers for play or restraints on self-stimulation. These results illustrate one instance in which multiple behavior change may be programmed in a predictable, lawful fashion by using “natural communities of sensory reinforcement.” 相似文献

In this investigation peer networks were formed consisting of students with autism and fourth grade peers. They were trained to tutor first grade students in sight word recognition. The purpose of the study was to determine if the target students could be trained effectively as tutors, to determine outcomes for the first graders, and to determine effects on social integration of network students. Effects were measured for implementation of tutoring steps, increases in sight words learned on a weekly basis for the tutees, and social interactions among network students during free time activities. Using a reversal design, with a multiple baseline component, results demonstrated higher gains on weekly pre- and posttests for first graders than control students who received classroom instruction only, successful implementation of peer tutoring steps by the network participants, and increased duration of social interaction time for the target students with autism and network companions. These findings were replicated in the following year. The peer network system for students with autism, thus not only increased their time and social engagement with typical peers but also provided a productive, socially acceptable activity for increasing academic performance for first graders exhibiting delays. 相似文献

Research and theory on medical technologysuggests that, for many expectant mothers, medicalintervention in pregnancy and childbirth results infeelings of alienation from their bodies and a lack ofcontrol over the childbirth experience. Few studies,however, examine the influence of medical interventionon the expectant father's experience of this significantlife event. In this study, we compare expectant fathers' and mothers' experiences with medicaltechnology during pregnancy and childbirth. In-depthinterviews were conducted with 15 primarily White,middle-class, married couples prior to and after the birth of their first child. Our findings revealdifferences in the impact of medical technology onexpectant mothers' and fathers' perceptions ofinvolvement and control over pregnancy andchildbirth. 相似文献
