To determine whether cognitive level rather than social class differences influence problem solving strategies, children from two SES levels were matched on cognitive abilities (preoperational, transitional and concrete operational) and administered a partial reinforcement task. (BD)

Black children (N=233) from three age levels and two socioeconomic (SES) levels were given five Piagetian tasks to determine if differences in sex were associated with differences in cognitive development levels. Results showed that higher SES children performed better than lower SES children on all five measures of reasoning, seriation,…

A total of 122 kindergartners, third and fifth graders viewed 30 pictures of familiar objects and interested on their free recall of the object names and their recognition of the original pictures. Half received instruction in adult recognition strategies, half in adult recall strategies. (MS)

The development of social cognitions about classroom life and their potential influence on children's classroom behavior were studied. Each of 360 first and fifth grade children from schools in middle class and working class neighborhoods were interviewed using booklets illustrating classroom behavior. The results indicated that children do…
