The depth of a group's personality resources: Impacts on group process and group performance

The present study examines the productivity of task groups in relation to the personality resources of its members and its two dimensions of group process: task focus and shared exchange. It is hypothesized that the depth of a group's personality resources impacts upon productivity both directly through the application of its member's personality resources to successful group outputs, and indirectly through the mediating agency of group process variables that also contribute separately to successful group outputs. To test these hypotheses, the performance of 43 groups in a 3-month social psychology class was measured across three course assignments. This averaged performance score was related to the groups' process scores and to their total levels of personality resources measured by a comprehensive personality inventory administered at the beginning of the groups' life. Using multiple regression, we found that a group's performance was predicted by total member intellect, openness (negatively), and emotional stability (negatively). Blocked regression revealed that group intellect exercised a direct effect upon group performance, but that the effects of group openness and group emotional stability on performance were mediated through the group's two group processes of task focus and shared exchange. It is hoped that this demonstration of a two-step approach to studying the impact of group member's personality through its direct effects on group performance and its indirect effect on performance-linked aspects of group process will be extended to other types of personality measures, and to other types of groups addressing different tasks in other cultural settings.     

Organisational Factors, Social Factors, and Women's Advancement

This study examines if organisation size and the degree to which the organisational hierarchy is male moderate the relationships between social factors (career and psychosocial functions of mentor support, and internal and external networks) and women's advancement in management. In all, 848 women in the Australian banking sector were surveyed. Results from moderator regression analyses found that, although male hierarchy does not moderate these relationships, the size of the organisation does. Specifically, career functions of mentor support and internal networks explain women's advancement more in small than in large banks. Recommendations for facilitating women's advancement in management are discussed.     

The role of injection cues in the associative control of the US pre-exposure effect in flavour aversion learning

Two experiments, using rats as subjects, examined the role of contextual cues in producing the unconditioned stimulus (US) pre-exposure effect in conditioned taste aversion. Experiment 1 showed a significant US pre-exposure effect, when the pre-exposure was conducted in a familiar context, and that a change of context between the pre-exposure and conditioning phases did not attenuate this effect. Experiment 2 demonstrated that extinction of injection-related cues after the pre-exposure stage attenuated the US pre-exposure effect, when the pre-exposure was conducted in either a familiar or a novel context. Taken together, these results support the associative explanation of the US pre-exposure effect in terms of blocking, incorporating a role for injection-related cues in the context blocking analysis of the US pre-exposure effect.     

Assessing inattention and impulsivity in children during the Go/NoGo task

Behavioural performance in the Go/NoGo task was compared with caregiver and teacher reports of inattention and hyperactivity‐impulsivity in 1,151 children (N=557 boys; N=594 girls) age 9–10 years old. Errors of commission (NoGo errors) were significantly correlated with symptom counts of hyperactivity‐impulsivity, while errors of omission (Go errors) were significantly correlated with symptom counts for inattention in both caregiver and teacher reports. Cross‐correlations were also evident, however, such that errors of commission were related to inattention symptoms, and errors of omission were related to hyperactivity‐impulsivity. Moreover, hyperactivity‐impulsivity and inattention symptoms were highly intercorrelated in both caregiver (r=.52) and teacher reports (r=.70), while errors of commission and omission were virtually uncorrelated in the Go/NoGo task (r=.06). The results highlight the difficulty in disentangling hyperactivity‐impulsivity and inattention in questionnaires, and suggest that these constructs may be more clearly distinguished in laboratory measures such as the Go/NoGo task.     

Sexual Orientation and Developmental Challenges Experienced by Gay and Lesbian Youths

Youths with a homosexual orientation face different developmental challenges during adolescence than those faced by heterosexual youths or individuals who recognize their homosexual orientation later in life. We discuss the impact of “coming out,” or defining a homosexual orientation, on the development and identity formation of youths who come out during adolescence. The process of coming out is presented as entailing four broad dimensions: recognizing oneself as lesbian or gay; exploring one's sexual orientation through the gay and lesbian community; disclosing one's sexual orientation to others; and becoming more comfortable with one's sexual orientation. Some of the major challenges faced by these youths are described, and future directions for research efforts are discussed.
