An experimental evaluation of three theories of auditory stream segregation

Three theories of auditory stream segregation were evaluated. In two-part trials, subjects heard an induction sequence, whose effects upon an immediately subsequent test sequence were measured. The rhythm and total duration of Induction Sequence tones were varied in two experiments. The similarity between induction and test sequences aided segregation, but rhythmic predictability and longer tone durations did not. Frequency alternation during the induction sequence was not necessary to induce segregation in the test sequence. Furthermore, peripheral processes inadequately account for the segregation effects found. The data suggest that, once a distinct percept emerges from an auditory scene, properties derived from the percept (particularly changes) are fed back to control the ongoing analysis of that auditory scene. A neural adaptation to stimuli with constant properties may form part of this analysis.     

Parent reports of child behavior problems: Bias in participation

This paper compares the characteristics of 274 children whose parents agreed to provide information about their children's functioning in research with children whose parents did not. Parents had provided permission for child participation in school-approved research. Measures included self-, peer, teacher, and parent ratings. Parents of minority children were less likely to participate than parents of nonminority children. Among nonminorities, children of parent participants were viewed as more socially skilled and liked by their peers; teachers rated them as having less attention problems, less depression, and better academic skills than children of nonparticipating parents. Among minorities, no differences emerged. Implications for research involving the use of parent ratings are discussed.Portions of this paper were presented at the annual meeting of the Society for Research in Child and Adolescent Psychopathology, Sarasota, Florida, February 1992. The authors appreciate the efforts of Shari Wasserstein in assisting with the organization of the data. The authors also appreciate the helpful comments of two anonymous reviewers.     

Parent Involvement in Early Intervention for Disadvantaged Children: Does It Matter?

This study investigated the association between parent involvement in early intervention and children's later school competence. Parents (N = 704) of children participating in the Chicago Longitudinal Study were interviewed retrospectively about their school involvement in preschool and kindergarten. Parents reported on the activities in which they participated and their frequency of program participation. Results indicated that even after controlling for family background, the number of activities in which parents participated in preschool and kindergarten was significantly associated with higher reading achievement, with lower rates of grade retention at age 14 (eighth grade), and with fewer years in special education. The frequency of parent involvement was only marginally associated with reading achievement but was associated with lower rates of grade retention and fewer years in special education. A confirmatory analysis indicated that teacher ratings of parent involvement in first and second grade were significantly associated with higher reading achievement in eighth grade, lower grade retention rates, and lower rates of special education placement through eighth grade. Findings support the benefits of parent involvement in early childhood programs.     

Performativity and Pedagogy: The Making of Educational Subjects

Building from J.L. Austin's concept of performative, this essay explores the production of subjectivity and of educational subjects by applying important work from Judith Butler on Foucault, Derrida, and as centrally illustrative, through an analysis of sex and gender. Given this analytical framework, the turn is then to queer performativity and the possibility of performative power in pedagogy. The last draws assistance from Valerie Walkerdine, Homi Bhabha and especially James Donald.     

Ambient Sexual Harassment: An Integrated Model of Antecedents and Consequences

Research on sexual harassment as a prevalent job stressor has focused primarily on outcomes for the direct targets of harassment; the antecedents and consequences ofindirectexposure to sexual harassment have not been explored. Ambient Sexual Harassment is proposed as an assessment of indirect exposure to sexual harassment. Ambient Sexual Harassment is defined as the general or ambient level of sexual harassment in a work group as measured by the frequency of sexually harassing behaviors experienced by others in a woman's work group. The integration of Ambient Sexual Harassment into the model of sexual harassment developed by Fitzgerald, Drasgow, Hulin, Gelfand, and Magley (1997) proposes that indirect exposure to sexual harassment will have similar antecedents and job-related, psychological, and health outcomes as direct exposure. An empirical test of the model, using samples of female employees from a public utility company (N= 455) and a food processing plant (N= 194), generally supports predictions.     

Between adolescents and aging grandparents: Midlife concerns of adults in the “Sandwich generation”

This study examined whether the midlife transition of men and women in the “sandwich generation” was related to their 15- to 19-year-old adolescent's psychosocial development and their relationships with their own aging parents (i.e., the grandparents). One hundred eighty-six (186) respondents representing adolescents, mothers, and fathers from 62 families completed questionnaires that assessed adolescents' psychological autonomy and involvement in adult-type roles, adults' midlife transition and marital quality, and adults' relationships with their aging parents. Analyses conducted by domain revealed that women reported greater concerns with midlife issues when their adolescents demonstrated fewer signs of psychological autonomy and involvement in adult-type roles whereas men reported more intense midlife concerns when they experienced more strain in their relations with their own parents. When adolescent, grandparent, and marital factors were considered conjointly, the results indicated that women's level of midlife concerns was still related to their adolescents' development, but men's level of concerns was most strongly related to their satisfaction with the quality of their marriages. The discussion focuses on adult women's and men's experience of the midlife transition in relation to adolescents' development, parents' relationships with aging grandparents, and marital quality.     

Psychological Science in Australia

This paper is a brief account of the Australian Strategic Review of the Psychology Discipline and its Research. Issues discussed include Australia's contribution to world research in psychological science, research funding, the age and qualifications of researchers, the social and economic benefits arising from the applications of research outcomes, multidisciplinary issues, the role of psychology in industry, links between the discipline and the profession of psychology, professional training, cross-cultural issues, and educational issues. Priorities for development of research and postgraduate training are identified, and include human factors and other areas related to technological change, clinical psychology with particular attention to health psychology, industrial and organizational psychology, and neuroscience and physiological psychology.
