The present study reinforced the two instructors of two students with profound mental retardation first for the instructors' training behaviors, then for improved student learning in a multiple baseline across responses design. Reinforcement of the instructors' training behaviors increased their training behaviors, replicating the findings of previous studies, but had no effect on student learning. When the reinforcement for the instructors was instead made contingent upon student learning, the student learning improved and the instructors' high level of training behaviors was maintained. In addition, the instructors began to request training for themselves. These findings suggest that staff motivation programs for instructors might usefully base the reinforcers not only on the instructor's performance, but on the progress of their students. 相似文献

This study examines the effects of patient age, gender, and depression on 88 advanced medical students' beliefs, attitudes, intentions, and behavior. Each subject heard an audiotaped patient portrayal. Patient age (32 or 67 years), gender, and depressive symptoms varied in a 2 × 2 × 2 between-subjects factorial design. All of the patients reported the same symptoms except that half of them also presented symptoms of depression. Questionnaires assessed beliefs about the patient's condition, attitudes toward the patient, treatment intentions, and recall of patient information. Expectations of an age bias were not substantiated. Females were rated less seriously ill, less likely to require laboratory tests, and more likely to receive medication than males. Among depressed patients, counseling and reassurance were more likely for females, and a nonpsychiatric consult was more likely for males. Recall of the symptoms presented was better for depressed patients. The implications for medical practice are discussed. 相似文献

The only hope of survival for children with a number of life-threatening illnesses is a successful bone marrow transplant (BMT). Unlike the treatment source for most therapies, the raw material for transplant therapy comes from a human being. Although many BMTs are autologous, utilizing the patient's own bone marrow, a large percentage of childhood BMTs rely on bone marrow from children or adolescents who are biological siblings to the sick child. Medical and legal systems are confronted with a dilemma when healthy children are needed to undergo minimally risky, yet somewhat painful, procedures for the benefit of their critically ill siblings. This article reviews legal issues involved in sibling bone marrow donation and psychological research that is relevant to those issues. The article concludes with proposed directions for future psycholegal research and a discussion of ethical issues that are not amenable to empirical investigation. 相似文献

The Web Interface for Statistics Education (WISE) project includes a World-Wide Web site to support the teaching of introductory social-science statistics courses. The site provides easy access to data bases, archived discussion lists, electronic journals, links to other sites focused on relevant statistics topics, and it includes a prototype of an on-line tutorial. The tutorial, which is the focus of the current paper, is designed to capitalize on special capabilities offered by the Web. The easy linkage between Web pages provides support for a highly interactive tutorial, which uses “failure-based” learning and immediate feedback. Students rated the tutorial as easy to use and indicated that it would have improved their initial statistics course. 相似文献

Homelessness among families has become a growing social problem for communities, yet little is known about the types of daily survival strategies such families employ. This paper presents results of a qualitative study of the coping narratives of 64 mothers living in temporary emergency shelters with their children. The women reported using a variety of coping responses to daily stressful events. These included the use of direct actions and more palliative strategies. Results suggest that stress and coping theory may be useful for understanding homelessness. Implications for program development and future research are discussed. 相似文献

This study focused on the impact of stimulus presentation format in the gating paradigm with age. Two presentation formats were employed—the standard, successive format and a duration-blocked one, in which gates from word onset were blocked by duration (i.e., gates for the same word were not temporally adjacent). In Experiment 1, the effect of presentation format on adults’ recognition was assessed as a function of response format (written vs. oral). In Experiment 2, the effect of presentation format on kindergarteners’, first graders’, and adults’ recognition was assessed with an oral response format only. Performance was typically poorer for the successive format than for the duration-blocked one. The role of response perseveration and negative feedback in producing this effect is considered, as is the effect of word frequency and cohort size on recognition. Although the successive format yields a conservative picture of recognition, presentation format did not have a markedly different effect across the three age levels studied. Thus, the gating paradigm would seem to be an appropriate one for making developmental comparisons of spoken word recognition. 相似文献

This study determined whether ambivalence toward Native peoples would result in amplified, or polarized, responses to members of the group, as assessed in terms of both general attitudes and social policy endorsements. In addition, it examined whether priming would mediate these effects, based on the notion that ambivalent attitudes contain both positive and negative dimensions that may be activated at different times. Induction of different mood states was used as an indirect priming manipulation. One hundred thirty-eight Canadian participants completed measures of ambivalence toward Native peoples and Canadians. One week later, these participants underwent a positive, neutral, or negative mood induction procedure. They then indicated their attitudes toward Native peoples and Canadians, and responded to social policy questions involving both groups. Participants who were highly ambivalent or not ambivalent toward Native peoples were retained for analysis; participants generally displayed low ambivalence toward Canadians. It was predicted and the results confirmed that only participants who were ambivalent toward Native peoples would display a relative response amplification effect: a greater difference between positive and negative mood states in their responses to Native peoples than in their responses to Canadians. 相似文献

This paper presents the application of an overlapping sampling technique used with a fast Fourier transform on electroencephalographic data. The use of this sampling and analysis technique is demonstrated on data in which steady state, rate of change, and critical event hypotheses are tested. The benefit of applying computer-generated three-dimensional graphics to the results of using this innovative sampling and analysis technique is emphasized. 相似文献

Factor analyses of child behavior problems have often yielded two broadband syndromes, Overcontrolled (e.g., worrying, fearfulness, withdrawal) and Undercontrolled (e.g., restlessness, fighting, disobedience). We explored whether these two broad-band syndromes might be identified for youngsters in Jamaica. We obtained teacher reports for 320 clinic-referred Jamaican youngsters on a 24-item problem checklist designed by Jamaican clinicians for the assessment of child behavior problems and subjected these to principal components analyses. Regardless of whether the sample was split according to age or sex, the analyses revealed factors similar to the Over- and Undercontrolled syndromes most often found in other cultures. The analyses also revealed school absence factors in each age and sex group; school avoidance was correlated with crying in children (aged 6–11) but with conduct problems in adolescents (aged 12–17). The findings suggest important similarities and possible differences between the factor structures of child behavior problems in Jamaica and the United States.This study was supported through grants from the University Research Council of the University of North Carolina at Chapel Hill and Sigma Xi, the Scientific Research Society, which we gratefully acknowledge.

The personal/group discrimination discrepancy (PGDD) refers to greater reporting of discrimination at the group than personal level. We examined whether the PGDD is one example of people's general tendency to distance themselves from negative attributes related to the social categories to which they belong, and whether this tendency varies as a function of ingroup identification. Female undergraduates (n=87) rated the extent to which positive and negative attributes, including being discriminated against, characterized themselves personally and women as a social category. As expected, negative attributes, including discrimination, were more strongly associated with the category than with the self, whereas positive attributes were more strongly associated with the self than with the category. Women who were lower in group identification were especially likely to show these discrepancy effects. The implications for personal and social identity are discussed. 相似文献
