The φ-maze is a novel implementation of the T-maze that can be used for various behavioral experiments. It consists of a start/goalbox from which a central alley leads to a choice point. Left and right arms return to the start/goalbox, where reinforcers are delivered. A holding chamber at the choice point can be used for delayed (non)matching-to-sample experiments. Lamps mounted under the translucent acrylic floor serve as visual stimuli. The design incorporates reliable and inexpensive automated guillotine doors and a modification of a commercially available pellet dispenser that allows the automated dispensing of Froot Loop reinforcers. The φ-maze has been used successfully in experiments involving spatial and visual alternation, visual discrimination, and delayed matching-to-sample. 相似文献

Relationships between sociometric indices and scores of 160 elementary-school children on the Children's Assertive Behavior Scale (CABS) were examined to determine whether this instrument differentiates children of varying levels of social competence. Children who obtained either high or low scores on peer nominations of friendship and admiration were identified and compared on CABS passive, aggressive, and assertive scores. Children who scored high on positive peer nominations responded in a significantly less aggressive manner than children who received low scores on such nominations. These effects were observed for the CABS format that consisted of stimulus situations involving adults but not for the form involving peers. With regard to responses toward peers, a significant interaction between sex and sociometric status emerged. These findings suggest the importance of incorporating subject variables such as race and sex as well as assessments of behavior toward both adults and children in isolating and training components of social skill.The authors wish to express their appreciation to Jean Birbilis, Gail Hammersly, Marieta Knopf, and Donna Wadley for their assistance in data collection and analysis. 相似文献

The Wilson-Patterson Conservatism Scale was given to 34 schizophrenic and 34 non-schizophrenic patients in a Dutch mental hospital. The absence of liberal-scoring schizophrenics was interpreted as consistent with the theory that the social withdrawal seen in chronic schizophrenia represents a strategy for coping with stimulus overload. Internal consistency analysis of C scale performance indicated that this test might be used to assess thought disorder in much the same way as the Bannister and Fransella Grid Test, but a great deal more economically. Furthermore, the questionnaire permits a more detailed examination of the source of inconsistency than does the repertory grid method. 相似文献

Two factors, level of processing (Craik & Lockhart, 1972) and congruity (Schulman, 1974), known to have large effects on the recall of experimenter-provided responses to questions, were examined in a series of five incidental learning experiments using subject-generated responses. The data show that manipulation of level of processing has the same effect on recall of subjectgenerated responses as it does on experimenter-provided responses. However, the effect of congruity is reversed for subject-generated responses. The data suggest that the difficulty of generating unrelated responses (“incongruous“ items) may account, at least in part, for the failure of the “principle of congruity“ with subject-generated responses. 相似文献

To evaluate the influence of spouse co-operativeness and couples training in the treatment of obesity, 29 obese men and women were assigned to three experimental conditions: (1) Co-operative spouse-couples training: subjects attended all meetings with spouses. Spouses were trained in modeling, monitoring, and reinforcement techniques; (2) Co-operative spouse-subject alone: subjects attended meetings alone even though their partners had agreed to become involved in treatment; (3) Non-cooperative spouse: subjects had spouses refusing to participate in the program, and attended sessions alone. At the 3-month and 6-month maintenance assessments. subjects in the spouse training condition lost significantly more weight than subjects in the other two conditions. Weight losses compared favorably to those of any controlled study with subjects in the couples training group averaging nearly 30 lbs lost after 8 months of treatment. In the absence of spouse training, subjects with co-operative spouses did no better than subjects with non-co-operative spouses. The findings suggest that spouse training may have a potent facilitative effect in weight reduction, and that this effect may promote long-term maintenance of weight loss. 相似文献

A simple circuit for a digital millisecond timer and event counter is described. The total cost of the unit including all components, a power supply, and an enclosure is less than $30. Daily use in simple reaction time experiments has demonstrated the reliability of the design. 相似文献

Effects associated with specific feedback modalities are neither clear nor well explored. The present paper provides an overview of feedback modalities typically used for the presentation of information from major physiological systems. Some consideration of feedback modality in relation to theory is provided with a discussion of trends in past applications. 相似文献

A multipurpose laboratory system incorporating a voice interactive terminal and graphic display system is described. The facility is designed to investigate some aspects of human performance on concurrent verbal and tracking tasks. The results of a pilot study showing decrements in dual-task performance are reported. 相似文献
