The effects of a cooperation contingency on behavior in a continuous three-person environment 总被引:1,自引:1,他引:0 下载免费PDF全文
Emurian HH Emurian CS Bigelow GE Brady JV 《Journal of the experimental analysis of behavior》1976,25(3):293-302
Five groups of three subjects resided for 10 or 15 days within a continuously programmed environment. Subjects followed a programmatic arrangement of required and optional private and social activities that determined the individual and group baseline behaviors into which experimental operations were introduced and withdrawn. A cooperation condition was in effect when all three subjects were required to select simultaneous access to a group area before it became available for use. A noncooperation condition was in effect when access to a group area could be selected by individual subjects, without regard to the other subjects' selections. For all groups, the effects of these two conditions on individual and group behaviors were investigated in reversal designs where several successive days occurred under each condition. Groups 1, 4, and 5 had the noncooperation condition interposed between cooperation conditions. Groups 2 and 3 had the cooperation condition interposed between noncooperation conditions. Durations of triadic activities, per cent of time in triadic activities, intercom use, and intersubject program synchronization were greater during cooperation conditions than during noncooperation conditions. These data show that a cooperation contingency within the behavioral program affected both social behavior and the collateral individual behavior necessary to execute the cooperation response. 相似文献

Begg (1978), among others, has recently argued that recognition performance is independent of the size and number of units stored in memory, that is, the degree of interitem organization. In four experiments, interactive imagery was contrasted with separation imagery on recognition memory. In the first two studies, the recognition of single words was better under separation instructions; in the final studies, in which recognition of pairs of words was required, performance was better following interactive imagery. Rather than being independent of the size of memory units, recognition depends upon the relationship between the size of the units encoded at learning and the nature of the test items themselves. 相似文献

Previous work has demonstrated that children who are poor readers have short-term memory deficits in tasks in which the stimuli lend themselves to phonetic coding. The aim of the present study was to explore whether the poor readers' memory dificit may have its origin in perception with the encoding of the stimuli. Three experiments were conducted with third grade good and poor readers. As in earlier experiments, the poor readers were found to perform less well on recall of random word strings and to be less affected by the phonetic characteristics (rhyming or not rhyming) of the items (Experiment 1). In addition, the poor readers produced more errors of transposition (in the nonrhyming strings) than did the good readers, a further indication of the poor readers' problems with memory for order. The subjects were tested on two auditory perception tasks, one employing words (Experiment 2) and the other nonspeech environmental sounds (Experiment 3). Each was presented under two conditions: with a favorable signal-to-noise ratio and with masking. The poor readers made significantly more errors than the good readers when listening to speech in noise, but did not differ in perception of speech without noise or in perception of nonspeech environmental sounds, whether noise-masked or not. Together, the results of the perception studies suggest that poor readers have a perceptual difficulty that is specific to speech. It is suggested that the short-term memory deficits characteristic of poor readers may stem from material-specific problems of perceptual processing. 相似文献

This study examined whether male and female supervisors differed in their delivery of performance feedback to subordinates. Male and female subjects supervised 2 confederate subordinates whose performance was stable and either above or below average. Supervisors regularly checked each subordinate's performance and could deliver one of several feedback messages. A MANOVA was performed on frequency of specific negative, general negative, specific positive, general positive, and neutral feedback messages, followed by step down analyses to isolate which dependent variables contributed uniquely. Male and female supervisors were distinguished by their use of specific negative feedback. Males were more likely to provide such messages to poorly performing subordinates, a result consistent with suggestions that males are characterized by a more directive leadership style. 相似文献

A critical overview is presented of workplace stress-management interventions. It is suggested that they have so far failed to deliver what they have promised. Evaluation studies fail to distinguish between the aims and objectives of primary prevention interventions, such as stress-management training, where potential benefits can only be assessed in terms of long-term outcomes, and secondary and tertiary interventions, such as counselling, where existing disorders are treated. Stress-management interventions are based on inadequate and oversimplistic theories which obscure the many conflicting interests of employees, employers and researchers, and ignore empirical evidence which suggests that individual well-being, attitudes to work, and work behaviours are minimally linked. It is suggested that alleviating the problems that people experience at work will remain elusive unless the conceptual problems in occupational stress are more fully acknowledged. 相似文献

General practice is an obvious but relatively untried context within which to practise family therapy. This paper describes the development of a family therapy clinic within a group general practice and considers the influence of the practice setting on the practical style and theoretical approach of the family therapy team. The influence of the clinic on the referring habits and on the consulting style of the GPs is also considered in the context of the changes taking place in the organization of general practice. 相似文献

In the course of a prospective longitudinal study, we examined age of onset of behavior problems in a group of boys and girls identified with attention deficit disorder (ADD) at age 11. Onset occurred during the preschool years, by the first year of schooling, or by the end of the second year of school. Onset was strongly related to informant source at age 11, pattern of comorbidity of disorder at age 11, and developmental language, perceptual motor, and IQ measures. Onset by the first year of schooling was particularly related to poor reading skills. By age 15, nearly three-quarters of those with onset of problems before age 6 had one or more DSM-III disorders. 相似文献
