A key prediction of cognitive theories of gender development concerns developmental trajectories in the relative strength or rigidity of gender typing. To examine these trajectories in early childhood, 229 children (African American, Mexican American, and Dominican American) were followed annually from age 3 to 5 years, and gender-stereotypical…

One hundred 18-month-olds were tested using sequential touching and following 4 different priming contexts using sets of toys that could be simultaneously categorized at either the basic or global level. An exact expression of the expected mean sequence length for arbitrary categories was derived as a function of the number of touches made, and a…

Looking times of 96 preschoolers were recorded as they were habituated on slides of sex-typed toys. After habituation, subjects were shown a test series of 24 slides. (Author/SS)

Three studies investigated: the effect of parent involvement on the exploratory behaviors of children rated as high-, moderate-, or low-explorers; whether maternal presence increased the exploration of low-exploratory children, decreased the exploration of high-exploratory children, or both; and whether maternal presence or mother/child…
