Discusses how Adolph's research is relevant to four themes that are foundational to contemporary research on the development of perception and action: (1) reciprocity between perception and action; (2) prospective control of behavior; (3) variation and selection in the development of new behaviors; and (4) contributions of age and experience.…

Examined recall by 14- to 32-month-olds for multistep event sequences experienced at 13 to 20 months. Found that within step-length groups, there were no age differences in the length of time over which memory was evidenced. With prompts by event-related props, age-related differences in memory appeared. Age-related effects were particularly…

Used Visual Expectation Paradigm to describe information processing changes and individual differences during first year of life. Found regular age changes in mean reaction time and variability but not in minimum reaction time, suggesting that growth rate of sensory-detection information is constant during first year but age changes occur in level…

Speculates on underlying processes for the reaction time variance and age differences in anticipation latency using the Visual Expectation Paradigm. Discusses the dichotomization of reactive and anticipatory behavior, limitations of longitudinal designs, drawbacks in using standard procedures and materials, and inferences that can be made…

Discusses two major contributions of Liben and Bigler's work: (1) introduction of new measures of sex typing; and (2) the proposal that there are two plausible ways in which gender attitudes and sex typing of self might be related. Considers the importance of context on gender salience for information processing. Asserts that Liben and Bigler's…

Responds to concerns that individual items included as stereotypes in the Occupation Activity Trait Scales (children's and adult's versions) are not highly stereotyped. Discusses future directions for research, noting that a developmental approach is critical to understanding gender differentiation establishment and that it is also important to…

Cross-sectional and longitudinal study of one- to six-year-olds in full-time child care assessed sequences and individual differences in development of social competence with peers. Study collects most extensive and varied data to date. Findings concern stability of individual differences, social classifications, influences of variations in…

Identifies contributions of Liben and Bigler's studies to gender development related to measuring self and other sex typing, developing a theoretical account of the self-other relation, and incorporating individual differences. Raises questions about measures used and interpretations of the findings. Suggests issues for future research:…

Four studies established the reliability and validity of measures for assessing attitudes toward others and sex typing of self in occupations, activities, and traits. A fifth study provided longitudinal data from children tested 4 times from age 11 to 13 years. Data supported conceptual distinctions among individual's gender attitudes toward…
