Bases for recent allegations of sex bias in Kohlberg's theory of moral development are discussed, and studies comparing the development of moral reasoning across the sexes are reviewed. A meta-analysis supported the conclusion that the overall pattern is one of nonsignificant sex differences in moral reasoning. (Author/RH)

Results suggest that (1) sex differences are found for some types of spatial ability but not others; (2) large sex differences are found only on measures of mental rotation; (3) smaller sex differences are found on measures of spatial perception; and (4) when sex differences are found, they can be detected across the life span.

Meta-analysis is a quantitative or statistical method for doing a literature review which replaces the traditional narrative method of reviewing literature. Statistics are taken from individual empirical studies and then statistical formulas are used to combine and test hypotheses. For feminist psychology, meta-analyses have usually been directed…

Twenty-four studies on creativity and bilingualism are compared in a table and text. Twenty of the studies found bilinguals to be more creative than monolinguals. Four studies found an interaction between sex and bilingualism. (DB)

Sex differences in language use have been examined for many years, but no clear-cut conclusions exist. A meta-analysis of the existing literature was conducted regarding powerful/powerless language use, including 30 studies, with a total combined sample size of 3,012. The overall correlation indicated that men use more powerful language than…

According to Gilligan (1982) there are two different orientations for describing moral development: a justice orientation characteristic of males, and a care orientation characteristic of females. Gilligan claims that the care orientation is confounded with the justice orientation in Kohlberg's (1983) conceptualization of Stage 3: mutual…

This study used meta-analysis research techniques to determine if there are differences in General Aptitude Test Battery (GATB) validities and test scores between males and females. The sample consisted of 26,111 subjects from 122 Specific Aptitude Test Battery (SATB) validation or revalidation studies analyzed since 1972. Four approaches were…

Research on the emergence of sex differences in spatial ability during early adolescence prompted a meta-analysis of 172 spatial ability studies conducted since 1974. The meta-analysis confirmed that there are actually several spatial abilities, that some types of spatial ability show marked sex differences while others show none, and that spatial…

Relates the development of theories concerning gender differences in mental ability and reexamines them using meta-analysis. Finds that the greatest difference is in one type of spatial ability, mental rotation. There is only a small difference in mathematical performance, and no difference in verbal ability. (DM)

Meta-analyses of sex differences in attitudes and affect specific to mathematics found that effects were small in size and similar to sex differences in mathematics performance. When differences did exist, the pattern was for females to hold more negative attitudes than males. However, males held more sex-stereotyped attitudes than did females.…

Whether or not there are sex differences in helping behavior is a question that has attracted interest from both theoretical and applied perspectives. A meta-analysis was conducted of 172 studies of helping behavior, coded for publication date, source, sex of author, sample size, setting, type of appeal for help, availability of other helpers, sex…

Combines meta-analysis and process analysis to clarify the nature and magnitude of gender differences in cognitive, psychosocial, and physical tasks and their implications for mathematics and science careers. Findings indicate that learning and working environments should be redesigned to promote gender equality. (FMW)

Both the career model and the decision model have been proposed to explain patterns of contraceptive use in teenagers. The career model views contraceptive use as a symbol of a woman's sexuality and implies a clear decision to be sexually active. The decision model is based on the subjective expected utility (SEU) theory which holds that people…

Examines the findings of 53 studies of sex differences in propositional logic, combinatorial reasoning, and proportional reasoning tasks. Finds sex differences for the latter two tasks to be vulnerable to Rosenthal's "file drawer" problem and effect size to be small for all tasks. Discusses possible explanations for sex differences in…

Current thought about the effects of single-parenting on children's sex-role development has supported (1) the traditional view that being raised in a single-parent home is deleterious to the well-being of children; (2) the conditional view noting that differences exist between children in father-absent and father-present homes (but only in…
