Subjects wielded occluded rods, with or without attached masses, and reported the distances reachable with their distal tips. Experiments 1–3 compared wielding about the wrist, the elbow, and the shoulder. Experiments 4 and 5 compared free wielding, using the whole arm, with wielding only about the wrist. The two comparisons, respectively, were of spatial and temporal variations in the rod’s rotational inertia. Perceived extent was found to be constant in both comparisons. This constancy was tied to the inertia tensorI ij defined about a point that remains a fixed distance from the object during wielding—an invariant of the spatially and temporally dependent patterning of mechanical energy impressed upon the tissues of the body. Discussion focused on the reciprocal action and perception capabilities of multisegmented limbs, the tensorial relations in the neurobiology of dynamic touch, and the strategy of understanding perceptual constancy through invariants. 相似文献

Two investigations examine the effect of similarity of sexual attitudes on (a) attraction to a stranger and (b) marital sexual satisfaction. In an experiment using undergraduates, manipulation of subject-stranger similarity in general affective orientation to sexuality affected attraction and other evaluative dependent variables. In the second investigation, married couples revealed sexual attitudes and sexual satisfaction. Husbands and wives were similar (r= 0.58, p < 0.001) in their affective orientations to sexuality. Discrepancy between the partners’ scores predicted sexual dissatisfaction in both partners. In addition, the wife's affective orientation to sexuality predicted more indices of sexual satisfaction and adjustment in both the wife and the husband than did the husband's affective orientation to sexuality. Finally, spouses with a positive affective orientation to sexuality were more accurate when judging their partner's sexual enjoyment, compared to spouses with a negative orientation. The findings have implications for the effects of similarity of attitudes on interpersonal attraction and on relationship quality. 相似文献

A proximal-distal theoretical framework was developed to examine the multivariate roots of homophobia. Using data from a sample of 288 undergraduates who had participated in a computer-assisted panel study over a three-year period, the effects on homophobia of distal and proximal family factors (e. g., parental education and family environment), distal and proximal individual factors (e. g., personality constructs and current beliefs), and proximal individual-situational factors (e. g., acquaintance with homosexuals) were tested in regression analyses. Both analyses employing sets of variables varying in proximity to the homophobic attitude and hierarchical regression employing variables contributing significantly in each set supported the proposed framework. All sets predicted significantly when regressed separately on homophobia; the sets containing the distal factors contributed most weakly, and the sets containing the proximal factors contributed most strongly. In hierarchical regression analysis, this pattern maintained such that the incremental increase in r2 decreased with the addition of each more distal set, with the most distal factors failing to contribute significantly to the prediction. The importance of study findings for attitude change efforts is discussed. 相似文献

A functional analysis of the self-injurious behavior (SIB) of 3 adults with profound developmental disabilities showed that each engaged in SIB in more than one assessment condition. Such outcomes may result from a failure to isolate the variable maintaining SIB, or they may reflect multiple sources of control over SIB. In order to identify more clearly the determinants of SIB, each subject was exposed to a series of treatments appropriate to one or both of the apparent functions of SIB. These treatments, applied sequentially on baselines appropriate to each behavioral function, identified the maintaining variables for SIB through differential outcomes across baselines. Results indicated that the SIB of 2 subjects was multiply controlled, confirming the outcomes of the functional analysis. However, the SIB of the 3rd subject was eliminated using a treatment designed for a single function, suggesting spurious results of the original assessment. Alternative interpretations of undifferentiated assessment data are discussed, as are analysis and treatment issues related to multiply determined behavior disorders. 相似文献

Eight children with developmental language impairment (LI) and eight age-, sex-, socioeconomic-status-, and I.Q.-matched controls were given tests of comprehension and expression of affective intent in spoken language and through facial expression. The LI children performed significantly more poorly than did controls in both comprehension and spontaneous expression of vocal affect. On tasks involving emotional facial expression, the opposite results were observed: The LI children were more dramatic in their expression of facial affect than were the controls. Children with language impairment appear to have a deficit in affective comprehension and expression that is modality-specific, i.e., limited to vocal affect. The heightened range of affective facial expression that they demonstrate may be a compensatory mechanism to offset their difficulties with vocal affect.This work was supported by grant 12-203 from the March of Dimes Birth Defects Foundation, and by NINDS grant NS22343 for the Center for the Study of the Neurological Basis of Language. 相似文献

In two experiments, conducted in Germany and the U.S.A., it was found that exposure to a rape report lowered self-esteem and positive affect in women who do not accept ‘rape myths’ (stereotypical beliefs which blame the victim and exonerate the rapist; Burt, 1980). Men high in rape myth acceptance (RMA) showed an increase in positive affect and self-esteem as a function of exposure to rape; men low in RMA and women high in RMA were largely unaffected. Both experiments demonstrated that these effects were specific to rape, as opposed to violence in general. These results support the feminist hypothesis that the threat of rape serves the function to exert social control over women and to sustain men's dominance. Potential cognitive mechanisms mediating the observed effects are discussed. 相似文献

This study compared the REST (Real Economy System for Teens) program with traditional talk therapy in the treatment of oppositional defiant adolescents. The REST program uses rules for five target behaviors: room care, personal hygiene, completion of chores, abusiveness, and safety violations. Objective measures and subjective parental ratings were taken. Twenty-five adolescents were assigned to each therapy group. In the REST program the adolescent was provided with only food and shelter. The adolescent had to earn money through the REST allowance program to pay for everything else. Earning the allowance was made contingent upon compliance with all rules for the five target behaviors. The results showed significantly greater improvement on all target behaviors for the REST program than for traditional therapy. In addition, parents of adolescents in the REST group reported that their adolescents seemed happier, more relaxed, and closer to them. 相似文献

The Cook and Medley (1954) Hostility (Ho) scale has been used in several important studies evaluating potential health consequences of hostility. A relative lack of compelling information about the construct validity of the Ho scale, however, has raised concerns about the appropriate interpretation of previous research. In this study, 60 married couples discussed a low conflict topic, a high conflict topic, and then a second low conflict topic. High Ho men responded to the high conflict topic with significant increases in self-reported anger and anxiety and overt hostile behavior, but low Ho men did not. Furthermore, compared to low Ho men, high Ho men blamed their wives more for their usual disagreements on the high conflict topic and saw their disagreement-engendering behavior as more intentional. Among women, Ho scores were weakly related only to overt hostile behavior. Finally, couples consisting of two low Ho persons displayed a uniquely agreeable interactional style. 相似文献

To test the hypothesized immaturity of juvenile delinquents' moral reasoning, the results of 15 studies of the moral reasoning of juvenile delinquents were integrated quantitatively using meta-analysis. Hedges and Olkin (1985) methods were used to (a) compute effect sizes, (b) test the homogeneity of the obtained effect sizes, and (c) test the statistical significance of the pooled mean effect size. The results supported the hypothesis that the moral reasoning of juvenile delinquents is immature. It was concluded that several other issues are in need of investigation. 相似文献
