Tested the comprehension of 3- and 4-year-old children with probable and improbable sentences in active and passive voice in order to evaluate the importance of semantic support for comprehension of passive sentences. (Author/SDH)

Three-, four- and five-year-old children were presented an array of metamemory tasks designed to test their understanding of variables which affect the difficulty of memory performance. (JMB)

The influence of perceptual factors and language comprehension on quantity judgments (number conservation) was assessed in children, aged 2-5. (ST)

Four types of semantic relation, assumed by different researchers to be implicated in the organization of semantic information, were investigated by means of false recognition and word association tasks presented to independent samples of 4- and 5-year-old children. (Author/SB)

The purpose of this study was to investigate the Ivanov-Smolensky procedure as an effective clinical device for the assessment of cognitive development in children under four years old. This procedure, expressly developed for assessing development in children with limited verbal skills, minimizes some of the research problems associated with young…

This study examines the longitudinal relationships between mastery motivation and differentiated measures of intellectual development assessed at 1 and 3 1/2 years of age in a sample of 35 children (21 boys and 14 girls).

The children were divided into three age groups representing one year intervals. The task for the study involved a "guessing" game in which a colored…

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…

The present report is the fourth of a series concerned with mental functioning and its development in early childhood.
