GLOBAL PROCESSING OF BIOLOGICAL MOTIONS

Abstract— The structure of the human form is quickly and unequivocably recognized from 10 to 13 points of light moving as if attached to the major joints and head of a person walking Recent psychophysical and computational models of this process suggest that these displays are organized by low-level processing constraints that delimit the pair-wise connections of the point lights In the current research, these low-level constraints were rendered uninformative by a masking paradigm The results from four experiments converged to show that the perception of structure in a point-light walker display does not require the prior detection of individual features or local relations     

“I’ve said I’m sorry,haven’t I?” A study of the identity implications and constraints that apologies create for their recipients

In contrast to previous research on apologies, which has examined their role in enhancing impressions of those issuing them (e.g., Darby and Schlenker, 1989), the research reported here draws upon Goffman’s (1955) analysis of the “corrective cycle” and is concerned with constraints associated with the receipt of apologies. Study 1 examines the implications for the actor of accepting, not accepting, or rejecting apologies. It is demonstrated that across a variety of judgments, most positive views of the actor result when apologies are accepted; least positive views are associated with their rejection. A follow-up study sought to establish whether this effect would occur under circumstances in which unconvincing apologies are rejected. Results indicate that the apology’s status (convincing versus unconvincing) has no bearing on perceptions of actors. Based on a hypothetical role-play format, Study 2 addresses the matter of whether actors experience a subjective sense of constraint upon receipt of unsatisfactory apologies. The data suggest that there exists a pronounced tendency to accept such apologies, though typically with conditions that would be specified to the offender. More general implications of the data are discussed.     

Ideological Beliefs About Family Practices: Contemporary Perspectives Among North Indian Families

Ninety-two dual-wage and 103 single-wage Indian families with a preschool-age child residing in extended and nuclear households provided assessments regarding their beliefs about the division of household chores, financial responsibilities, childcare, and filial obligations. Analysis focused on possible differences in belief structures that may be attributed to the gender of the parent, family structural living arrangement, and maternal employment outside of the home. Husbands and wives did not differ in ideological beliefs on any of the components assessed, but differences did emerge as a function of family structural arrangements and whether or not the wife worked outside of the home. Data are discussed in terms of possible changes in ideological beliefs about family functions and practices and the broader socio-cultural factors operating within Indian society.     

Concordance Between Mothers' and Children's Reports of Somatic and Emotional Symptoms in Patients with Recurrent Abdominal Pain or Emotional Disorders

Mother–child concordance regarding children's somatic and emotional symptoms was assessed in children with recurrent abdominal pain (n = 88), emotional disorders (n = 51), and well children (n = 56). Children between 6 and 18 years of age and their mothers completed questionnaires assessing the children's somatic symptoms, functional disability, and depression. Mothers of children with recurrent abdominal pain reported more child somatic and depressive symptoms than did their children, and mothers of children with emotional disorders reported more child depressive symptoms than did their children. Higher levels of maternal distress were associated with greater mother-child discordance in the direction of mothers reporting more child symptoms than did their children. No significant child age or sex differences were found in concordance patterns.     

On the time course of negative priming: Another look

In two experiments, the pattern of persistence of negative priming effects across delay intervals of 500 and 2,500 msec was assessed using a within-subjects, random sequencing of delays. Neill and Valdes (1992; Neill, Valdes, Terry, & Gorfein, 1992) have argued that a within-subject experimental design is required for decay of negative priming to be seen, in contrast to results reported elsewhere (e.g., Tipper, Weaver, Cameron, Brehaut, & Bastedo, 1991) showing stable negative priming effects across delays. In neither experiment was substantial evidence of decay detected, raising questions for the notion that suppression necessarily declines across brief temporal intervals and for the assertion that episodic retrieval is the sole source of negative priming.     

The relationship between frontalis muscle activity and self-reports of headache pain

The relationship between levels of frontalis muscle activity and self-reports of pain was evaluated in two studies. In Study I frontalis muscle activity and self-reports of pain collected during biofeedback treatment of muscular contraction headache clients were correlated. In Study II frontalis EMG activity was increased and decreased using biofeedback techniques while concurrent reports of headache pain were recorded. The results of Study I indicated a significant relationship between EMG activity and reported headache pain for only two of the five subjects studied. The biofeedback procedures in Study II were associated with reliable increases and decreases in EMG activity. Concordance between EMG and pain reports occurred only during the EMG increase condition. Overall correlations were significant for one of the 2 subjects. The results suggest that EMG activity may not be sufficient to account for pain reports in all chronic headache clients, and variables other than EMG activity may be influencing reports of pain in some patients.
