This longitudinal study combined, in a single study, different aspects of children's knowledge about mental phenomena and thus could investigate relations among the development of language, theory of mind, and later metamemory. In total, 183 German children were tested at ages 3, 4, and 5. Each time of testing included a set of theory-of-mind…

Two studies found infants' scores on the Range of State Cluster of the Neonatal Behavioral Assessment Scale with Kansas Supplements to correlate significantly with visual discrimination performance at three months of age. The correlation with behavioral state organization contradicted the prediction that orientation scores would predict visual…

Investigated infants' integration of visual information across space and time. In four experiments, infants aged 12 months and 6 months viewed objects after watching light trace similar and dissimilar shapes. Infants looked longer at novel shapes, although six-month-olds did not recognize figures taking more than 10 seconds to trace. One-year-old…

Investigated the development of social referencing (children's looks toward parents, instrumental toy behaviors, affective expressions, etc.) in 40 infants aged 6-9, 10-13, and 14-22 months. Results indicated that looking behavior of younger children may function differently from that of older children, and social referencing involves a number of…

Visual behavior of infants was assessed with multiple discrimination tasks week to week from four to seven months of age. Task to task reliability was low, but attentional averages from week to week were reliable. Generally, infants with shorter fixations showed more novelty preferences, and infants' shift rate improved with age. (SKC)

Observed social interactions of 110 Embu children in rural Kenyan community bimonthly between 15 and 30 months of age. Found children who talked frequently, and whose vocalizations were responded to, performed better on assessment measures and showed more positive affect than children who had fewer social interactions or were carried a great deal.…

Examines preschool children's ability for advance planning and mishap prevention or remediation related to familiar events. Indicates that children three to five years old appear to use general event knowledge in constructing verbal plans. However, developmental differences in the quality of plans suggests that the ability of using general…
