All Georgia children in Grades 4, 8, and 12 (250,000) were given mental ability and reading and arithmetic achievement tests in the Fall of 1971. Four demographic variables from the 1970 census, the educational expenditure per child, average daily attendance, and 12 test variables were inter-correlated. All correlations between mental ability and fertility ratios are negative. All are significant. Also, all correlations between fertility ratios and measures of school achievement are negative and significant. Per capita expenditure does not have a significant effect on school achievement at any grade level.

General mental ability (GMA) has long been considered one of the best predictors of training success and considerably better than specific cognitive abilities (SCAs). Recently, however, researchers have provided evidence that SCAs may be of similar importance for training success, a finding supporting personnel selection based on job-related requirements. The present meta-analysis therefore seeks to assess validities of SCAs for training success in various occupations in a sample of German primary studies. Our meta-analysis (k = 72) revealed operational validities between ρ = .18 and ρ = .26 for different SCAs. Furthermore, results varied by occupational category, supporting a job-specific benefit of SCAs.

Abstract. The purpose of this study was to test for race and sex differences in general mental ability (GMA) retest performance and to identify the psychological mechanisms underlying these differences. An initial and retest administration of a GMA assessment separated by a six-week span was completed by 318 participants. Contrary to our predictions, we found that race, sex, and emotional stability failed to moderate GMA retest performance. However, GMA assessed via another ability test and conscientiousness both partially explained retest performance. Additionally, we found that retesting may reduce adverse impact ratios by lowering the hiring threshold. Ultimately, our findings reinforce the need for organizations to consider race, sex, ability, and personality when implementing retesting procedures.
