The Role of Attitudes in Reactions Toward Diversity in Workgroups1

The present study examined attitudes toward diversity as a moderator of outcomes of diversity in workgroups. Two studies were conducted that focused on the development of the Attitudes Toward Diverse Workgroups Scale (ADWS) and on the impact of diversity attitudes on task performance and psychological reactions in actual face‐to‐face diverse brainstorming groups. The first study supported the internal consistency and stability of the ADWS and revealed that it was related, in the predicted way, to the Big Five and general prejudice. The second study revealed that high scores on the productive and affective dimensions of the ADWS enhanced brainstorming performance (quality of ideas) in actual diverse groups and positive psychological reactions to the group experiences, respectively.     

TOWARD BETTER META‐ANALYTIC MATRICES: HOW INPUT VALUES CAN AFFECT RESEARCH CONCLUSIONS IN HUMAN RESOURCE MANAGEMENT SIMULATIONS

Simulations and analyses based on meta‐analytic matrices are fairly common in human resource management and organizational behavior research, particularly in staffing research. Unfortunately, the meta‐analytic values estimates for validity and group differences (i.e., ρ and δ, respectively) used in such matrices often vary in the extent to which they are affected by artifacts and how accurately the values capture the underlying constructs and the appropriate population. We investigate how such concerns might influence conclusions concerning key issues such as prediction of job performance and adverse impact of selection procedures, as well as noting wider applications of these issues. We also start the process of building a better matrix upon which to base many such simulations and analyses in staffing research. Finally, we offer guidelines to help researchers/practitioners better model human resources processes, and we suggest ways that researchers in a variety of areas can better assemble meta‐analytic matrices.     

Longitudinal Effects of Television on Children's Leisure-Time Reading A Test of Three Explanatory Models

Using a sample of 1,050 Dutch elementary schoolchildren who were in Grades 2 and 4 at the outset of the research, this study investigated (a) the longitudinal effects of television viewing on the frequency with which children read books and comic books at home, and (b) the causal mechanisms that underlie television's effects on leisure-time reading. The children were surveyed three times, at 1-year intervals. Structural equations analysis suggested that television viewing reduced children's comic book reading only in the period from Year 2 to Year 3. Book reading, however, was found to be reduced by television viewing over both measurement periods. The data suggest that two causal mechanisms underlie television's reductive effect on children's book reading: (a) a television-induced deterioration of attitudes toward book reading, and (b) a television-induced deterioration of children's ability to concentrate on reading.
