Two problems in the investigation of predictive bias in tests, the effect of unreliability of the predictors, and the effect of excluding a predictor from the regression equation on which there are preexisting group differences, are discussed. (Author)

A meta-analysis of outcomes from 32 studies investigating pretest effects was conducted. For all outcomes the average effect size was +.22, indicating an elevating effect of pretest on posttest. Duration of time between pre- and posttesting was also related to effect size. Researchers should continue to include pretest as a design variable.…

Examined seasonal migration in a sample of northeastern older adults (N=1279). Seasonal migrants were more likely married, retired, and reported higher levels of income and education. Most migrated to destinations in the southeast because of better climate and recreational opportunities. (Author/JAC)

Tested the relationship between psychological depression and feeling old in 308 older adults. Results indicated that regardless of age, people who felt older were more depressed and less healthy than people who felt younger.

Argues that the housewife role itself, which both housewives and employed wives share, is anomic.

The wife's perception of marital communication was negatively related to the tendency for the couple to choose female sterilization, conditional on female labor force participation. Communication questions are…

Examined the relationship between age and perceived health status in 660 adults. Number of symptoms was the strongest predictor of perceived health status employed in this analysis, followed by age, education, and race. Persons over 60 tend to perceive their own health in a significantly more positive fashion. (Author/JAC)

Results of a statistical study of language in 30 infants suggest that two acquisition styles (nominal/pronominal and referential/expressive) are developing in parallel. Only for children heavily emphasizing one strategy can a distinctive style be determined. Results at 20 months were only partially predictive of performance at 28 months. (MSE)

Results showed differences on 16 items including family history, drug and alcohol use, events preceding the crime, and relationship between offender and…

Studied levels of psychological functioning of survivors (N=147) of the Beverly Hills Supper Club fire. Results showed the group as a whole was more impaired than the comparison sample. Survivors who were at the fire were less impaired than survivors not at the fire. (WAS)
