Techniques for the production of point-light and fully illuminated video displays from identical recordings

Illumination of only a few key points on a moving human body or face is enough to convey a compelling perception of human motion. A full understanding of the perception ofbiological motion from point-light displays requires accurate comparison with the perception of motion in normal, fully illuminated versions of the same images. Traditionally, these two types of stimuli (point-light and fully illuminated) have been filmed separately, allowing the introduction of uncontrolled variation across recordings. This is undesirable for accurate comparison of perceptual performance across the two types of display. This article describes simple techniques, using proprietary software, that allow production of point-light and fully illuminated video displays from identical recordings. These techniques are potentially useful for many studies of motion perception, by permitting precise comparison of perceptual performances across point-light displays and their fully illuminated counterparts with accuracy and comparative ease.     

Change and stability with respect to attitudes and practices related to marriage in Ashkabat,Baku, and Ankara: Three Turkic cultures

Changes in practices and views related to marriage were investigated by conducting interviews with respondents of Turkic origin residing in the capitals of Turkey, Turkmenistan, and Azerbaijan: three Turkic cultures with different historical backgrounds. The results revealed that, with some exceptions, practices related to marriage demonstrated a trend toward modernity in all three samples. The most rapid and consistent pattern of transition was evidenced for the Ankara sample, the Ashkabat sample revealed both change and stability, whereas the Baku sample demonstrated the least amount of change with respect to practices related to marriage. Less change was evidenced for attitudes. The results were discussed with reference to historical events and value systems surrounding national identities of the respective cultures. It was argued that, in the case of Turkmenistan, symbols of the clan system were retained and changes were consistent with basic values of the Oguz family. In the case of Azerbaijan, relative gender equality and elaborate ceremonies involving the extended family were construed as attempts at preserving Turkish identity in the face of Russian domination. Lastly, it was argued that the official endorsement of Western‐style families, contact with the West, and rejection of Eastern ways for over a century in Turkey has resulted in the most consistent pattern of relationships between different indicators of the Western‐style family.     

Guided Affective and Cognitive Imagery to Enhance Self-esteem Among Hawaiian Children

This article discusses the use of guided affective and cognitive imagery to enhance self-esteem among children of Hawaiian ancestry. Children who participated in the intervention strategy, which consisted of 10 group sessions, had significantly higher scores on some areas of self-esteem.     

Developmental differences in schema dependency for temporally ordered story events

This research project was undertaken to investigate whether temporally ordered story events would be recalled in logical sequence as opposed to presentation order by various ages and under various task conditions. A 24-hour delayed condition was used as well as immediate recall. Six-year-olds, 8-year-olds, and adults were asked to recall four narratives. Instructions given were either vague or specifically required subjects to recall events exactly as they had been presented. Following the delayed recall, a picture-sequencing task was adminstered to assess whether picture cues would enable subjects to demonstrate awareness of input order even though they had reordered events in recall. All subjects reordered more during the delayed recall than during the immediate recall. Age differences (p<0003) occurred in the ability of subjects to demonstrate verbatim memory on the picture-sequencing task. Findings suggest that in contrast to adults, once children have reordered narrative events in memory, they no longer have an alternative verbatim version available. Results also suggest a greater schema dependency in children than in adults in recall tasks.     

Correlates of child abuse potential

Coercion theory provided the theoretical rationale for the present study. The hypothesis was that mothers' reports of child behavior problems and mothers' reports of external locus of control would be related to abuse potential. A total of 95 mother-child pairs were screened for child abuse potential during visits to a hospital-based pediatrie clinic. Following brief interviews, mothers completed three measures: Milner's Child Abuse Potential Inventory, Levenson's Locus of Control Scales, and the Revised Behavior Problem Checklist. Perceptions of control by powerful others and by chance were related to abuse potential for mothers of both sexes. Mothers' reports of their sons' anxiety-withdrawal and conduct-disorder behavior problems were related to abuse potential. There was a significant association among lie scores, internality, and abuse potential for mothers of female children. Mothers with high abuse potential reported significantly more behavior problems in their children. The findings were discussed in relation to coercion theory.Portions of this paper were presented at the biennial meeting of the Society for Research in Child Development, Detroit, April 1983. This research was conducted by the first author in partial fulfillment of the requirements for the Ph.D. at the University of Miami under the direction of Drs. Keith G. Scott and Annette M. La Greca. The first author wishes to thank the members of the committee, Drs. Herbert C. Quay, Simon B. Miranda, Daryl Greenfield, and Julia Rosenkrans, for their many contributions. Also, special thanks to the University of Miami Child Protection Team for their continuous support and guidance, and special appreciation to the mothers and children who participated in the study.     

Modes of social support: The social support behaviors (SS-B) scale

Conclusion The SS-B appears to be a promising measure of five modes of available supportive behavior: emotional support, socializing, practical assistance, financial assistance, and advice/guidance. The measure was designed to assess supportive behavior available from family and from friends. For specific purposes the measure might be modified to tap enacted supportive behavior, as was done in Study 4, or might focus on different sources (cf. Tardy, 1985). Further evidence of the divergence of mode-specific scales would be valuable and might be demonstrated by comparing samples with mode-specific deficits, by comparing support received for different problem types (in a more sophisticated fashion than was done here), and by showing differentiated associations between modes of support and various outcome variables. The reliable and valid assessment of specific modes of supportive behavior is an important agenda item in social support research: Such a measure would allow more elaborate theories to be tested, and will undoubtedly prove essential in a complete understanding of social support processes.     

Decisions about the axes of disoriented shapes

Subjects were timed as they made decisions about the location of an asterisk placed to the left, right, top, or bottom of disoriented shapes, and their reaction times were plotted as a function of the angular departure of the shapes from the upright. In Experiment 1, the shapes were letters, and the functions suggested that the subjects generally mentally rotated some internal representation of each letter to the upright in order to decide whether the asterisk was to the left or the right, regardless of whether the letters were vertically symmetrical (A, T, U, V), horizontally symmetrical (B, C, D, E), or asymmetrical (F, G, R, L). For decisions about top and bottom, mental rotation rarely occurred, although there was some evidence for it in the case of horizontally symmetrical letters. Experiment 2 showed that mental rotation was not involved when subjects made one response if the asterisk was to the left or right, and another if it was at the top or bottom. In Experiment 3, the shapes were relatively unfamiliar architectural symbols, and in this case mental rotation was most strongly induced by those decisions requiring mirror-image discrimination, that is, left-right decisions for vertically symmetrical shapes and top-bottom decisions for horizontally symmetrical ones. Taken overall, the results suggest that there are two task ingredients that may induce mental rotation: One is the labeling of the left and right sides of a disoriented shape, and the other is the discrimination of mirror images.     

Stability and change in role innovation and life plans

Trends in women's labor force participation between 1967 and 1981 are noted as background to this 14-year longitudinal study of 117 women who graduated from college in 1967 and were studied in 1967, 1970, and 1981. The women represent a stratified random sample of the graduating class of 1967 from one large midwestern university. The three strata are role-innovators (women in male-dominated occupations, traditionals (women in female-dominated occupations), and moderates (women in occupations having 30 to 50% women). Samplewide changes are consistent with national trends: increased employment, increased role-innovation, greater educational achievement, and later and smaller families than expected in 1967. There was also a dramatic increase in perceived conflict between marriage and career. Within these trends, however, large parts of the sample showed strong consistency: 81% of the original role innovators and 69% of the original traditionals were still role-innovators and traditionals, respectively, in 1981. This longer term consistency overrode a great deal of temporary change in the traditional direction between 1967 and 1970, particularly for the role innovators and moderates. Much of this temporary shift was associated with early child rearing. Factors associated with increased role innovation and increased traditionality were the importance women gave to having a career, the relative priorities they placed on career vs family, their expectations of marriage-career conflict, and their expections of husband's acceptance of their career. Increased role innovation was also associated with attaining more education, not marrying, and having fewer children.
