A functional analysis identified the reinforcers for 3 participants' problem behavior, but only relatively mild problem behaviors (e.g., screaming, disruption) were observed when all topographies produced tested consequences. We then conducted an extinction analysis in which specific topographies produced a reinforcer while all other topographies were on extinction. The extinction analysis confirmed that the same reinforcer identified in the initial functional analysis maintained more severe topographies of problem behavior (e.g., aggression). In addition, results of the extinction analysis indicated that 2 of the participants displayed patterns of responding consistent with a response class hierarchy hypothesis, in which less severe problem behavior frequently occurred prior to more severe topographies. The 3rd participant displayed a response pattern indicative of differential reinforcement effects. 相似文献

Separating the acquisition of prerequisite skills from the learning of skills in vivo may be a more efficacious procedure for self-help training of low functioning developmentally delayed children. Two procedures for training independent use of a fork at meals were compared using two equivalent groups of three subjects each, in multiple baseline design. Using previously accepted procedures, one group was trained during meals while the experimental group received prerequisite training making use of simulated food (styrofoam pieces). Data during training, generalization-to-meal, and follow-up were collected. For 6 months following training, the efficacy of prerequisite training was upheld. The complexity of individual responses to the singular or conjunctive use of social and edible reinforcement for the purpose of self-feeding skill generalization and maintenance, is discussed. 相似文献

We evaluated a training package designed to teach menstrual care skills to five mild to severely mentally retarded women. Three specific skill areas (changing stained underwear; sanitary napkin; and both stained underwear and sanitary napkin) were task analyzed and taught in a sequential manner. Results of a multiple-baseline design across women indicated that the training package was successful in teaching these skills; the women continued to perform the skills during naturally occurring menses up to 5 months following termination of the study. 相似文献

Patterns of intellectual ability were examined in 81 children with verbal deficits identified by a Low Verbal/High Performance WISC profile. The results of verbal and nonverbal tests of intellectual functioning were factor-analyzed, and three groups of children were defined based on patterns of factor scores. Group 1 consisted of children with a Specific Language Disability (SLD) but good Abstract Reasoning ability, while Group 2 included SLD children with good Sequencing-Memory skills. Group 3 children displayed a General Language Disability (GLD) with deficits in both abstract reasoning and sequencing memory. The intellectual patterns were related to cognitive interpretations and found to have educational implications, with Group 1 children reading adequately, Group 2 children showing somewhat poorer reading skills, and Group 3 children reading very poorly. These findings emphasize the importance of identifying subgroups of children with verbal deficits and demonstrate the feasibility of extracting relatively specific cognitive information from global measures of intelligence. The results question the appropriateness of applying traditional assumptions regarding cognitive organization derived from studies of normal children to atypical groups of children. 相似文献

Gleason's theorem for R
3 says that if f is a nonnegative function on the unit sphere with the property that f(x) + f(y) + f(z) is a fixed constant for each triple x,y,z of mutually orthogonal unit vectors, then f is a quadratic form. We examine the issues raised by discussions in this journal regarding the possibility of a constructive proof of Gleason"s theorem in light of the recent publication of such a proof. 相似文献

We conducted functional analyses of aberrant behavior with 4 children with developmental disabilities. We then implemented functional communication training (FCT) by using different mands across two contexts, one in which the establishing operation (EO) that was relevant to the function of aberrant behavior was present and one in which the EO that was relevant to the function of aberrant behavior was absent. The mand used in the EO-present context served the same function as aberrant behavior, and the mand used in the EO-absent context served a different function than the one identified via the functional analysis. In addition, a free-play (control) condition was conducted for all children. Increases in relevant manding were observed in the EO-present context for 3 of the 4 participants. Decreases in aberrant behavior were achieved by the end of the treatment analysis for all 4 participants. Irrelevant mands were rarely observed in the EO-absent context for 3 of the 4 participants. Evaluating the effectiveness of FCT across different contexts allowed a further analysis of manding when the establishing operations were present or absent. The contributions of this study to the understanding of functional equivalence are also discussed. 相似文献

"IF YOU LET ME PLAY SPORTS" 总被引:4,自引:0,他引:4
This study tests a model specifying that girls' precollege participation in sporting activities will foster positive body images, enhanced perceptions of physical competence, and more flexible gender identities, which, in turn, predict higher college self-esteem. A sample of 220 college females (mean age = 19.65 years) provided retrospective reports of their precollege sport involvement and contemporaneous assessments of body image, perceived physical competencies, gender identity, global self-esteem, and other psychosocial variables. Consistent with prior reports on male and mixed-gender samples, greater precollege sport participation predicted higher self-esteem in this exclusively female sample. Follow-up path analyses and tests for mediation revealed that the model's intervening variables totally mediated the sport participation/self-esteem relationship. The patterning of these data implies that participating in sports promotes females' self-worth by fostering physical competencies, favorable body images, and gender flexibility, and, in the absence of any such psychosocial benefits, participation in sports has little salutary effect on and can even undermine self-esteem. 相似文献

The goal of the present research was to assess the reliability and validity of the fiftyitem Modified Godfrey-Richman ISM
Scale (M-GRISMS). The sample consisted of seventy-one female and sixty male introductory psychology students. Test items included
various ethnic groups (Racism subscale), religious groups (Religion subscale), and the Heterosexist and Sexist subscales.
Each of these was parsed into various subcategories, e.g., the Racism subscale assessed attitudes toward African-Americans,
Asian-Americans, European-Americans, Hispanics, and Native Americans. The final version of the M-GRISMS (the M-GRISMS-M) was
found to be highly reliable and valid. Eight independent factors traversed two or more “isms.” 相似文献
