Legitimizing the Leader: Endorsement by Male Versus Female Authority Figures

Subjects viewed a videotaped group discussion by a leader and four other group members and evaluated each of them for leadership competence. The leader, either a man or a woman, was either personally endorsed ("legitimized") or unendorsed by either a male or a female authority figure. Legitimation raised both leaders' performance evaluations. Legitimation by the female authority affected the leaders' evaluations, overall, as much as legitimation by a male authority. For the male leader, legitimation by the male and female authority figures produced equal impact. However, legitimation by the female authority figure produced significantly greater impact on evaluations of the female leader's performance than the same legitimation by a male authority figure. The data suggest that female authority figures can be effective legitimizers of both sexes, but male authority's endorsements of a female subordinate may be viewed as suspect.     

Visual persistence of spatially filtered images

Periodic stimuli such as sine-wave gratings and checkerboard patterns have been used in many studies of visual perception. It is well known that with such stimuli, visual persistence increases as spatial frequency increases and as contrast decreases. It is not clear, however, that similar relationships obtain for aperiodic stimuli such as natural images. Digitized images of objects (a face and a vase) were submitted to two-dimensional Fourier analysis. Four pairs of spatial frequency band-limited images were created for each image. Each pair consisted of a normal (NP) and a scrambled (SP) phase version, with the magnitude spectrum and space-averaged luminance the same within each pair. Filter bandwidths were one octave wide. Threshold persistence was measured for each spatially filtered image. Visual persistence for SP images increased significantly as spatial frequency increased, whereas no significant differences were found for NP images. This suggests that the temporal processing of complex, aperiodic visual images is influenced by the spatial frequency and contrast of local features within the image and cannot be predicted by space-averaged estimates of contrast and spatial frequency.     

Religiosity and psychological distress among blacks

The influence of religion on mental well-being has been the subject of controversy for a long while. Yet little is known about this relationship among black Americans. Using a probability-based sample of 451 urban black Americans, this study examines gender differences in religiosity and explores the ramifications for mental health. Findings indicate that females are more religious than males as evidenced by their greater participation in organizational forms of religious practice such as meetings and other gatherings. However, for both males and females, religiosity varied significantly by age and by marital and parental status. On the other hand, there were no differences in religiosity according to levels of education, income, and employment status for either males or females. With regard to mental health, greater religiosity was associated with fewer depressive symptoms for both males and females. Further, in the event of stressful circumstances, the influence of religion on mental well-being for females was direct, while religious involvement appeared to have an indirect or stress- buffering effect for males.     

The relations among cry characteristics, demographic variables, and developmental test scores in infants prenatally exposed to methadone

This study examined the relations among developmental test scores, infants' demographic characteristics, and cry features. Cry features were strongly related to developmental test scores at all ages, suggesting that use of the infants' cry characteristics can help to identify those infants at greatest risk for later developmental problems.     

SCIENTISM, INTERPRETATION, AND CRITICISM

Abstract. What is the relationship between natural science, social science, and religion? The dominant paradigm in contemporary social science is scientism, the attempt to apply the methods of natural science to the study of society. However, scientism is problematic: it rests on a conception of natural science that cannot be sustained. Natural scientific understanding emerges from an instrumental and objectifying relation to the world; it is oriented toward control and manipulation of the physical world. Social-scientific understanding, by contrast, must begin with a practical and meaningful relation to the world: it is oriented toward the mediation of values and objective possibilities in the social world. Social science is therefore a form of practical reason based on objective claims. But while social-scientific understanding starts with interpretation, its possibilities by no means end there. In particular, by developing abstract and objectified models of society as a system, social science opens existing social organization to critical reflection. Religion, by contrast, is a form of speculative reason about ultimate values, based on subjective claims of religious experience. Social science nevertheless shares with religion an orientation toward values and concern with the “good life.”     

The effects of spatial phase on reaction time to spatially filtered images

Summary Many studies of visual perception have used periodic stimuli such as sine-wave gratings and checker-board patterns. It is well known that reaction time (RT) to such stimuli increases with increasing spatial frequency and decreasing contrast. While this is the case with periodic stimuli it is not clear that these relationships obtain for aperiodic stimuli such as natural scenes. A digitized image of an object (a vase) was submitted to two-dimensional Fourier analysis. Four pairs of spatial frequency band-limited images were created for each image. Each pair consisted of a normal-phase (NP) and a scrambled-phase (SP) version, with the magnitude spectrum and space-averaged luminance the same within each pair. Filter band-widths were 1 octave wide. Manual RT was measured for onset and offset of each spatially filtered image. Mean RT for SP images increased significantly with increasing spatial frequency, while no other significant differences were found with the NP images. This suggests that the temporal processing of complex, aperiodic images is influenced by the spatial frequency and contrast of local regions within the image, rather than by the space-averaged contrast of the entire image, and cannot be predicted by global estimates of contrast and spatial frequency.     

TV commercials as achievement scripts for women

This study suggests that sex stereotypes implicitly enacted, but never explicitly articulated, in TV commercials may inhibit women's achievement aspirations. Men and women (N=180) viewed locally produced replicas of four current, sex-stereotyped commercials, or four replicas that were identical except that the sex roles were reversed, or (control) named their favorite TV programs. All subjects then wrote an essay imagining their lives “10 years from now.” The essays were coded for achievement and homemaking themes. Women who viewed traditional commercials deemphasized achievement in favor of homemaking, compared to men and compared to women who had seen reversed role commercials. The reversed role commercials eliminated the sex difference in net achievement focus. Control subjects were indistinguishable from their same-sex counterparts in the traditional condition. The results identified some social changes needed to make “equality of opportunity” a social reality for women as well as men.     

SOCIOBIOLOGY, ETHICS, AND THEOLOGY

Abstract. The topic of sociobiology and ethics opens up a range of questions that have to do with important relationships: between the history of nature and human being, between biological evolution and psychosocial evolution, between is and ought , between language usages in one domain and another. The task of ethics is properly to discern what sociobiology has to tell us about the fundamentals of life and persuasively to direct our actions in accord with those fundamentals, in a manner that is consistent with our essential humanity. From the theological perspective all of this transpires within the creative will of God.     

GOD AND CHAOS: THE DEMIURGE VERSUS THE UNGRUND

Abstract. The human quest for meaning is an attempt to bring experience into conjunction with illuminating concepts. The second law of thermodynamics is of wide human concern, because it touches experience which is existentially charged and therefore which humans must interpret in broad metaphysical terms. Five types of experience have been incorporated into the second law: running down, degeneracy, mixed-up-ness, irreversibility of time, and emergence of new possibilities. The dominant Western tradition (Plato) places these experiences within a metaphysical scheme that evaluates them negatively, whereas a minority tradition (Berdyaev) evaluates them positively. The former makes entropy anti-God; the latter places entropy within God.
