Construct Validity of Raven's Advanced Progressive Matrices for African and Non‐African Engineering Students in South Africa

We test the hypothesis that the Raven's Advanced Progressive Matrices has the same construct validity in African university students as it does in non‐African students by examining data from 306 highly select 17‐ to 23‐year olds in the Faculties of Engineering and the Built Environment at the University of the Witwatersrand (177 Africans, 57 East Indians, 72 Whites; 54 women, 252 men). Analyses were made of the Matrices scores, an English Comprehension test, the Similarities subscale from the South African Wechsler Adult Intelligence Scale, end‐of‐year university grades, and high‐school grade point average. Out of the 36 Matrices problems, the African students solved an average of 23; East Indian students, 26; and White students, 29 (p<.001), placing them at the 60th, 71st, and 86th percentiles, respectively, and yielding IQ equivalents of 103, 108, and 118 on the 1993 US norms. The same pattern of group differences was found on the Comprehension Test, the Similarities subscale, university course grades, and high‐school grade‐point average. The items on the Matrices ‘behaved’ in the same way for the African students as they did for the non‐African students, thereby indicating the test's internal validity. Item analyses, including a confirmatory factor analysis, showed that the African/non‐African difference was most pronounced on the general factor of intelligence. Concurrent validity was demonstrated by correlating the Matrices with the other measures, both individually and in composite. For the African group, the mean r=.28, p<.05, and for the non‐African group, the mean r=.27, p<.05. Although the intercepts of the regression lines for the two groups were significantly different, their slopes were not. The results imply that scores on the Raven's Matrices are as valid for Africans as they are for non‐Africans.     

An Evolutionary Game Theoretic Perspective on Learning in Multi-Agent Systems

In this paper we revise Reinforcement Learning and adaptiveness in Multi-Agent Systems from an Evolutionary Game Theoretic perspective. More precisely we show there is a triangular relation between the fields of Multi-Agent Systems, Reinforcement Learning and Evolutionary Game Theory. We illustrate how these new insights can contribute to a better understanding of learning in MAS and to new improved learning algorithms. All three fields are introduced in a self-contained manner. Each relation is discussed in detail with the necessary background information to understand it, along with major references to relevant work.     

Who's That Girl: Television's Role In The Body Image Development Of Young White And Black Women

Although findings indicate a connection between frequent media use and greater body dissatisfaction, little attention has focused on the role of race. Accordingly, this study investigates the relation between television viewing and body image among 87 Black and 584 White women. Participants reported monthly viewing amounts of mainstream and Black-oriented television programs as well as body attitudes as measured by the Eating Disorders Inventory, the Body Esteem Scale, and the Body Shape Questionnaire. Results suggest different patterns predicting body image for White and Black women. Among White women, viewing mainstream television predicted poorer body image, while viewing Black-oriented media was unrelated to body image. Among Black women, viewing Black-oriented television predicted healthier body image, while viewing mainstream television was unrelated to body image. Ethnic identity also predicted healthier body image among Black women, and appeared to moderate, to some extent, the contributions of viewing Black-oriented programming.     

Gender Role Self-Concept and Gender-Typed Communication Behavior in Mixed-Sex and Same-Sex Dyads

The focus of this study was the relation between both gender role self-concept and gender role attitudes with gender-related behavior of interacting partners. We observed gender-typed communication behaviors of mixed-sex and same-sex dyads and measured gender role self-concept and gender role attitudes. Thirty mixed-sex dyads, 19 women dyads, and 15 men dyads participated in a behavior observation study. The results revealed that the activation of gender role self-concept varies depending on the gender of the interacting people. Furthermore, we found that context and gender of the interacting persons moderated the relation between self-concept and behavior. Participants' gender role attitudes did not correlate with their own behaviors but did with their partners' behaviors.     

Aesthetics of Surrender: Levinas and the Disruption of Agency in Moral Education

Education has long been charged with the taskof forming and shaping subjectivity andidentity. However, the prevailing view ofeducation as a project of producing rationalautonomous subjects has been challenged bypostmodern and poststructuralist critiques ofsubstantial subjectivity. In a similar vein,Emmanuel Levinas inverts the traditionalconception of subjectivity, claiming that weare constituted as subjects only in respondingto the other. In other words, subjectivity isderivative of an existentially priorresponsibility to and for the other. Hisconception of ethical responsibility is thusalso a radical departure from the prevailingview of what it means to be a responsible moralagent. In this paper, I use jazz improvisationas a metaphor to focus on three interrelatedaspects of ethical responsibility on Levinas'saccount: passivity, heteronomy, andinescapability. I then point toward some waysin which reframing responsibility andsubjectivity along this line might offer newpossibilities for conceiving subjectivity andmoral agency in education.     

Antecedents and Potential Moderators of the Relationship Between Attitudes and Hiring Discrimination on the Basis of Sexual Orientation

A sample of 236 undergraduates (most of whom were White women) rated resumes in which gender, masculinity/femininity, and sexual orientation were manipulated while qualifications were kept constant. Overall, participants rated lesbian and gay male applicants less positively than heterosexual male applicants, but more positively than heterosexual women. Religiosity, beliefs in traditional gender roles, beliefs in the controllability of homosexuality, and previous contact with lesbians and gay men were related to attitudes toward lesbians and gay men, which was in turn related to beliefs about employing them. Several factors were hypothesized to moderate the relationship between beliefs about employing lesbians and gay men and discrimination, although the expected relationships were not found. Implications and directions for future research are discussed.     

Biological bases of face preference in 6-week-old infants

Six-week-old infants (N =40) who started the experiment in either a calm or crying state, received sucrose from an experimenter, while in eye contact with her. Sucrose was delivered either by syringe or on a pacifier. After 3.5 min., the experimenter retired, the mother came into the test room and placed her infant over her shoulder en face with a video camera. The experimenter and a confederate, both dressed identically, sat in front of and slightly to either side of the infant and the infant could choose to look at either experimenter. To minimize position bias, experimenters switched sides every 30 sec. To maintain a stable level of infant attention, they simultaneously called the baby's name at 10 sec. intervals. When an infant looked at one or the other experimenters, she raised her thumb in camera view. Only crying infants who sucked a sweet pacifier showed a preference for their experimenter. As a group none of the other infants did so. However, there was a wide distribution of sucking times in calm week 6 infants. Choice was linearly related to sucking duration. Infants who sucked for substantial periods of time, showed a strong preference for the experimenter. Those who sucked for minimal periods of time strongly preferred the confederate. Based on these findings and ones from 9- and 12-week-old infants, a model is presented in which preference in this experimental paradigm is determined by idealized levels of central activation. These levels may be inferred from the normal crying function at a particular age.     

Developmental trajectories of internalising behaviour in the prediction of adolescent depressive symptoms

Using a community‐based Australian birth cohort, groups with distinct longitudinal profiles (trajectories) of internalising behaviour from early childhood through mid‐adolescence were identified for boys and girls from parent ratings. Six internalising trajectories were identified for both genders, comprising stable, decreasing, and increasing pathways. Hierarchical regression models predicted the contribution of internalising trajectories to self‐reported age 17 depressive symptoms for males (n = 557) and females (n = 633), after controlling for the effects of a range of adolescent precursors. Internalising trajectories and adolescent psychosocial factors, each contributed to the prediction of subsequent depressive symptoms, with girls and boys on increasing internalising trajectories and boys on a fluctuating high trajectory particularly at risk. Results suggest that parent ratings can identify coherent internalising behaviour pathways that originate early in life and influence subsequent adjustment.     

The Meaning of the Sperm Donor for Heterosexual Couples: Confirming the Position of the Father

In the literature, relatively little attention has been paid to the meaning of donor involvement in the intimate couple dyad. The current study aimed to enrich our understanding of couples' meaning‐making regarding the anonymous sperm donor and how they dealt with the donor involvement. Semi‐structured interviews were conducted with nine couples, who had at least one child conceived through sperm donation. Our thematic analysis showed that the donor conception was seen as a different path to create a normal family. Once the family was formed, most couples avoided talking about the donor because it was perceived as disrupting men's growing confidence in their position as father. Participants tried to confirm the position of the father to protect the family relationships. Uncertainties about how they were perceived as parents showed the continuing dominance of genetic ties within our social discourse. Participants also dealt with reminders of the donor in their daily life. Overall, they tried to manage the space taken up by the donor and to protect the position of the father. We relate our findings to literature on topic avoidance and shared obliviousness in families. For counseling practice, it could be useful to explore couples' meaning‐making about the donor as this seemed to serve family functioning.     

FAMILY CONFLICT MODERATES EARLY PARENT–CHILD BEHAVIORAL TRANSACTIONS

The reciprocal transactions that shape early parent–child relationships are influenced by contextual stress, such as family conflict. Although family conflict is a salient stressor to the family system, few studies have considered how parent–child transactions vary according to exposure to family conflict. The present study examined how family conflict alters early parent–child behavioral transactions. We utilized three waves of data from a multisite longitudinal study of low‐income families (N = 2, 876), child age 14 months, 24 months, and 36 months, to identify behavioral transactions of positive and negative maternal (supportiveness, negative regard) and child (engagement, negativity) behaviors. Results indicated that family conflict at 14 months diminished the positive association between maternal supportiveness and child engagement, and amplified the inverse association between maternal negativity and child engagement. Family conflict at 14 months also was associated with increased stability of child negativity and subsequent increased maternal negative regard at 36 months, in part via increases in 24‐month child negativity. In sum, family conflict occurring early in childhood predicted and moderated behavioral transactions between young children and their mothers.
