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…

Distributions of child attachment classifications in mother-child dyads in which the child evidenced physical problems were similar to distributions in normal…

Maintains that fathers' role in attachment and the impact of the quality of…
