Self-reinforcement in operant situations generally refers to those arrangements in which the subject delivers to himself a consequence, contingent on his behavior. However, it is noted that the definition of all other types of reinforcement make its delivery contingent on the subject's behavior. What is actually at issue is the agent who defines whether or not the response required for reinforcement has been met. In self-reinforcement, the subject himself defines this. In the laboratory, this requirement is machine-defined; in school examinations, it is teacher-defined; and in many clinical self-control situations, it is also independently defined. A reinforcement contingency presupposes such independence, absent in self-reinforcement. Implications for research and practice are discussed and alternative formulations are offered. 相似文献

In the last few years, a number of asymptotic results for the distribution of unrotated and rotated factor loadings have been given. This paper investigates the validity of some of these results based on simulation techniques. In particular, it looks at principal component extraction and quartimax rotation on a problem with 13 variables. The indication is that the asymptotic results are quite good. 相似文献

Sex-related effects on clinicians' attributions of parental responsibility for child psychopathology
Christine V. Abramowitz Stephen I. Abramowitz Lawrence J. Weitz Bennett Tittler 《Journal of abnormal child psychology》1976,4(2):129-138
An attempt was made to reproduce and extend previously reported data suggesting the operation of sex-related bias in clinicians' attributions of parental involvement in children's psychopathologies. More and less sex-role traditional male and female family-oriented practitioners were shown contrived profiles in which a boy or girl was described as masculine or feminine role-deficient, and apportioned maternal versus paternal blame, treatment focus, adjunctive therapy need, and likelihood of sabotage. As in the previous study, mothers were implicated slightly more than fathers and also were viewed as requiring relatively greater therapeutic attention by female than by male clinicians. However, several earlier findings were not replicated. Overall, the results offer only marginal support for the notion of sex-related practitioner bias. 相似文献

The perceptual complexity of intransitive adverbials, truncated passives and full passives was investigated in two experiments using rapid visual processing tasks. Both forms of passive were found to be more complex than the intransitive adverbials, presumably because of the lack of correspondence of surface and base orders. However, deletion of the logical subject in truncated passives did not increase their complexity relative to full passives. 相似文献

Forty male undergraduates were provoked following their ingestion of high or low doses of either alcohol or delta-9-tetrahydrocannabinol (THC). The expression of physical aggression was related to the quantity of alcohol ingested. The high dose of alcohol instigated more intense aggression than the low dose. The high dose of THC, on the other hand, did not increase aggressive behavior. In fact, it tended to produce a weak suppression effect. 相似文献
