Computers and girls: Rethinking the issues

A perspective is developed about emerging sex differences in the use of computer technology in education. Computers tend to be conceptually assimilated to the category of science/mathematics/technology, and thus acquire some of the traditional qualities of differentiated interest among boys and girls. Findings from several research projects are reported which point to patterns of difference in educational settings. It is argued that sex differences emerge in relation to the functions computers serve and the organization of learning settings of which they are a part.The preparation of this article and the research reported was supported by the Spencer Foundation, the Department of Education, and the National Institute of Education.

Self‐Enhancement in Military Leaders: Its Relevance to Officer Selection and Performance

We report on two studies in which we measured army cadets' tendencies to engage in two types of self‐enhancement: communal self‐enhancement (a moralistic bias in self‐presentation) and agentic self‐enhancement (an egotistic bias in self‐presentation). These self‐presentation styles were then related to their selection and performance as military leaders. In Study 1, scores on self‐enhancement questionnaires were used to predict selection decisions for 206 applicants to an army officer training program. We found that applicants who were higher in either communal or agentic self‐enhancement were more likely to be accepted for leadership training. In Study 2, we evaluated peer and superior ratings of 94 military cadets' leadership, reflecting leadership emergence and leadership effectiveness, respectively. We found that communal self‐enhancement negatively predicted leadership emergence, with those ratings becoming more negative over a 3‐year time‐span, whereas agentic self‐enhancement positively predicted leadership effectiveness. Our results imply that, at least in the present military context, people making selection decisions should be particularly aware of the relations between (a) applicant self‐enhancement tendencies and those decisions, and (b) high communal self‐enhancement in officer trainees and negative evaluations by their cadet peers.     

The emergence of gender differences in physical aggression in the context of conflict between young peers

It is well known that a gender difference in physical aggression emerges by the preschool years. We tested the hypothesis that the gender difference is partly due to changing tactics in peer interaction. Observations of girls’ and boys’ social initiatives and reactions to opportunities for conflict were made, using the Peer Interaction Coding System (PICS) in four independent samples of children between 9 and 36 months of age, which were aggregated to form a summary data set (N= 323), divided into two age bands (below or above 24 months of age). Linear mixed‐model analyses revealed significant age by gender interactions in the use of bodily force in response to peers’ initiatives and in the tendency to use bodily force at later stages of conflicts with peers. The gender difference in use of force was not explained by differences in the use of verbal tactics. These cross‐sectional findings suggest that girls are initially more likely than boys to use reactive aggression, but then desist, whereas boys increase their use of force to defend their territory and possessions. The difference between older and younger girls likely reflects girls’ abilities to regulate their behaviour in response to social challenges and the fact that girls are explicitly socialized to yield to peers’ demands.
