The present study fills a crucial gap in literature surrounding the lives of African American men by exploring factors that shape the quality of these men's friendships. Drawing on data from a sample of 171 African American men, the study examines the relative utility of subjective religiosity, subjective spirituality, advice exchange, and affective sharing as predictors of the level of perceived support from male and female friends. Findings reveal age differences in subjective religiosity, subjective spirituality, and in level of advice and affective exchange in men's same-sex as well as cross-sex friendships. Age differences emerged in men's perceptions of the supportiveness of their friendships with women but not with men. Age was not a predictor of perceived supportiveness of same-sex or cross-sex friendships. Subjective religiosity did not predict support in same-sex or cross-sex friendships. Subjective spirituality positively predicted perceived support in men's same-sex friendships but not in cross-sex friendships. Implications of these findings are discussed.  相似文献

We used repetition blindness to investigate the nature of the representations underlying identification of manipulable objects. Observers named objects presented in rapid serial visual presentation streams containing either manipulable or nonmanipulable objects. In half the streams, 1 object was repeated. Overall accuracy was lower when streams contained 2 different manipulable objects than when they contained only nonmanipulable objects or a single manipulable object. In addition, nonmanipulable objects induced repetition blindness, whereas manipulable objects were associated with a repetition advantage. These findings suggest that motor information plays a direct role in object identification. Manipulable objects are vulnerable to interference from other objects associated with conflicting motor programs, but they show better individuation of repeated objects associated with the same action.

Most research on persuasion examines messages that directly address the attitude of interest. However, especially when message recipients are inclined to resist change, indirect methods might be more effective. Because values are rarely attacked and defended, value change could serve as a useful indirect route for attitude change. Attitudes toward affirmative action changed more when the value of equality was attacked (indirect change) than when affirmative action was directly attacked using the same message (Experiments 1-2). Changes in confidence in the value were responsible for the indirect change when the value was attacked (controlling for changes in favorability toward the value), whereas direct counterarguments to the message were responsible for the relative lack of change when the attitude was attacked directly (Experiment 2). Attacking the value of equality influenced attitudes toward policies related to the value but left policy attitudes unrelated to the value unchanged (Experiment 3). Finally, a manipulation of value confidence that left attitudes toward the value intact demonstrated similar confidence-based influences on policies related to the value of freedom (Experiment 4). Undermined value confidence also resulted in less confidence in the resulting policy attitudes controlling for the changes in the policy attitudes themselves (Experiments 3 and 4). Therefore, indirect change through value attacks presented a double threat-to both the policy attitudes and the confidence with which those policy attitudes were held (potentially leaving them open to additional influence).

At least four conceptually distinct mechanisms may mediate relations between parasite-stress and cultural outcomes: genetic evolution, developmental plasticity, neurocognitive flexibility, and cultural transmission. These mechanisms may operate independently or in conjunction with one another. Rigorous research on specific mediating mechanisms is required to more completely articulate implications of parasite stress on human psychology and human culture.  相似文献

A subject's performance under a conditional-discrimination procedure defines conditional relations between stimuli: “If A1, then B1; if A2, then B2.” The procedure may also generate matching to sample. If so, the stimuli will be related not only by conditionality, but by equivalence: A1 and B1 will become equivalent members of one stimulus class, A2 and B2 of another. One paradigm for testing whether a conditional-discrimination procedure has generated equivalence relations uses three sets of stimuli, A, B, and C, three stimuli per set. Subjects learn to select Set-B and Set-C comparisons conditionally upon Set-A samples. Having been explicitly taught six sample-comparison relations, A1B1, A1C1, A2B2, A2C2, A3B3, and A3C3, subjects prove immediately capable of matching the B- and C-stimuli; six new relations emerge (B1C1, B2C2, B3C3, C1B1, C2B2, C3B3). The 12 stimulus relations, six taught and six emergent, define the existence of three three-member stimulus classes, A1B1C1, A2B2C2, and A3B3C3. This paradigm was expanded by introducing three more stimuli (Set D), and teaching eight children not only the AB and AC relations but DC relations also—selecting Set-C comparisons conditionally upon Set-D samples. Six of the children proved immediately capable of matching the B- and D-stimuli to each other. By selecting appropriate Set-B comparisons conditionally upon Set-D samples, and Set-D comparisons conditionally upon Set-B samples, they demonstrated the existence of three four-member stimulus classes, A1B1C1D1, A2B2C2D2, and A3B3C3D3. These larger classes were confirmed by the subjects' success with the prerequisite lower-level conditional relations; they were also able to select Set-D comparisons conditionally upon samples from Sets A and C, and to do the BC and CB matching that defined the original three-member classes. Adding the three DC relations therefore generated 12 more, three each in BD, DB, AD, and CD. Enlarging each class by one member brought about a disproportionate increase in the number of emergent relations. Ancillary oral naming tests suggested that the subject's application of the same name to each stimulus was neither necessary nor sufficient to establish classes of equivalent stimuli.  相似文献

The role of valence and instrumentality was examined in predicting three work-related criteria in a military setting: satisfaction, perceived effort, and turnover. A total of 323 enlisted men responded to desirability and instrumentality scales for each of four categories of performance outcomes: extrinsic rewards, personal fulfillment, recognition, and autonomy. Multiple regression analyses indicated that the different outcome types varied substantially in their relationship to the criteria, ranging from strongly positive to no relationship to strongly negative. Furthermore, the salience of valences and instrumentalities changed as a function of the criterion being predicted in a manner not deducible from current expectancy-valence models. Several implications of the results were discussed in terms of assumptions underlying general expectancy-valence approaches to motivation.This research was supported in part by Grant DAHC19-77-G0017 to New York University (Samuel Shiflett, principal investigator) from the Army Research Institute for the Behavioral and Social Sciences.

America's judicial system is both exceptionally punitive and demonstrably unjust toward racial minorities. While these dual realities are structured into America's institutions, we propose they are also partially sustained by the intersection of ideologies that are both racialized and sacralized. Using multiple waves of the General Social Surveys and a unique measure that asks Americans to choose between two forms of judicial injustice (wrongful conviction or erroneous acquittal), we examine how white racial identity intersects with biblical literalism to bolster America's bent toward unjust punitiveness. In the main effects, Americans who affirm biblical literalism are more likely to show a preference for convicting the innocent, as are whites compared to Black Americans. Examining interaction effects, however, we find whiteness moderates the influence of biblical literalism such that only white biblical literalists (as opposed to non‐white biblical literalists or white non‐biblical literalists) are more likely to prefer wrongful conviction. Indeed, in our full model, being a white biblical literalist is the strongest predictor of preferring wrongful conviction. We theorize that preference for wrongful conviction over erroneous acquittal stems, at least in part, from the combination of sacralized authoritarianism and perceived racial threat.  相似文献
