The primary focus of this research is upon a secondary or derived aspect of maternal employment, namely, the supervision of children whose mothers work. (Author)

The investigators assessed the effects of two variables, overt labeling and cultural differences, on the short-term memory performance of young children. (Authors)

Videotapes of two 17-month old children -- each child sometimes described as a boy and sometimes as a girl -- were shown to 85 adult middle-class subjects, who rated attributes of the children on questionnaires containing sex role items. (Authors/RY)

The effects of rate of stimulus presentation and reinforcement conditions on the two-choice discrimination learning performance of MA matched normal and familial retarded children were examined. (Authors)

The present study investigated some properties of the environment that control an infant's response to his mother's departure and, in particular, the readiness with which he follows her. (Authors)

The primary purpose of this study was to investigate conservation acquisition across subcultural groups. (Author)

A child's history of reinforcement is regarded as setting a standard that determines what current rates of reinforcement will be deprivational or satiational for him. (Author)

The present study tested the feasibility of using a purely verbal recognition-memory procedure with young children and examined the role of verbal associations in the memory encoding of such children. (Author)

These findings suggest that a high density of negative feedback induces both reflective and impulsive children to make fewer errors than does positive feedback. (Authors)

A replication of a previous longitudinal study of American children -- this time with Guatamalan children. (RY)

The purpose of the study was to determine (a) whether there are differences in the way in which Negro and white experimenters interact with Negro and white subjects; and (b) whether such differences influence performance on tests of motor impulse control, reflectivity, innovative behavior, and curiosity.

Results of two experiments support the view that logical development can occur when there is no direct internalization of a societal language and that deaf adolescents are capable of propositional thought despite their language deficiency. (Author/WY)

Results of an experiment with children ages 3-11 years performing serial recall tasks suggest that it is not until about age 5 years that children's overt speech reaches a functional stage that would justify internalization. (Author/WY)

Cognitive style was modified in a sample of 50 impulsive and 50 reflective fourth-grade boys. Subjects viewed a film-mediated model displaying a response style opposite to their own cognitive style. The specific cues in the model's behavior which facilitated shifts in cognitive style varied with the intellectual levels of the subject. (Author/WY)
