Described are three experiments which probed children's sensitivity to structure or organization in visual patterns. Each experiment employed a different paradigm (complexity judgment, discrimination learning, recognition learning, and memory) in order to tap different aspects of children's use of structural information. Subjects were children in…

This study examines the interactive roles of social, cultural, and cognitive developmental factors in determining children's moral and achievement judgments. A total of 1485 male and female Iranian children/students of diverse social background (ranging in age from 4-18) served as subjects. Subjects were asked to evaluate (reward/punishment) the…

This survey sought to estimate the economic value of children to their parents in two peasant villages in Java and Nepal in order to examine the economic interpretation of fertility.

The effects of modeling and corrective feedback on conceptual rule acquisition and retention were studied with a total of 48 3- and 4-year-old children. Equal numbers of children from each age group were randomly assigned to one of four training groups: modeling, corrective feedback, modeling and corrective feedback, and a no modeling/no…

In this study, the occupational advancement of black and white workers of comparable ages is compared through longitudinal census data. Two specific hypotheses are tested which propose (1) large and systematic racial differentials exist in the effect of mobility on occupational advancement between firms; and (2) differentials in intrafirm…

A total of 23 children were observed from age 1 to 3 in order to assess day-to-day learning environments and their effect on intellectual development. Observers used a time-sampling technique to code behaviors for one hour on three to five separate occasions during each of four periods: age 12-15 months, 18-21 months, 24-27 months and 30-33…
