Human development is thought to evolve from the dynamic interchange of biological dispositions and environmental provisions; yet the effects of specific biological and environmental birth conditions on the trajectories of cognitive and social-emotional growth have rarely been studied. We observed 126 children at six time-points from birth to 5…

Objective: To examine developmental and behavioral status of children in child welfare (CW) over time, by intensity of CW involvement using a national probability sample. Methods: As part of the National Survey of Child and Adolescent Well-being (NSCAW), data were collected on 1,049 children 12-47 months old investigated by CW agencies for…

Diagnosing autism and PDD-NOS at very early ages has become a major priority in the field of mental health. More recently, researchers have also come to realize the importance of identifying co-occurring conditions of psychopathology in this population. In the present study, 309 children between 17 and 37 months of age who had been identified as…

Behavioral symptoms of comorbid psychopathology of 651 children 17-37 months of age who were at risk for developmental disabilities were studied using the BISCUIT-Part 2. In Study 1, norms and cutoff scores were established for this new scale on this sample. In Study 2, frequency of response on the 52 items measured was reported. Problems in…

This paper focuses on possible relations between early peer skills and developing cognitive abilities. One promising area for discovering relations between cognitive development and peer interaction appears to be related to the young child's developing ability to differentiate self from other, that is, decentration. Decentration is typically…

Hearing loss as a result of meningitis, now the leading nongenetic cause of deafness in infants and young children, may be reduced by the introduction of the HiB (Hemophilus influenzae type B) vaccine. It is highly effective, relatively safe, and recommended for most children over 24 months and high risk children 18-24 months old. (VW)

Multimethod assessments of temperament were obtained from 89 twins at 18 and 24 months of age. Ratings of subject reaction to restraint and parent ratings of temperament plus coordination of these temperament dimensions with analogous dimensions obtained at 12 months provided evidence of stability of temperament across six-month intervals during…

Discusses strategy-like behaviors in a memory-for-location task found in four studies of 18- to 24-month-old children. Interprets results as evidence of an early natural propensity to keep alive what must be remembered, a rudimentary version of what will later become more elaborate mnemonic strategies. (Author/CB)

Provides instructions for creating inexpensive activities and toys for infants and toddlers to supplement major toy purchases in early care programs. Includes instructions for making bean bags, cellophane snakes, sock bracelets, one-piece puzzles, milk carton blocks, a pounding bench, paint gloves, and people puzzles. (KB)

Analysis indicated that young children consistently differed in the initiation of interaction and the conflict contributions they elicited from peers. Relationship effects were found in games and contingent interaction. (RH)

This commentary on the research reported in this monograph stresses the importance of the analogy between the processes involved in pretense comprehension and the processes required to comprehend written or spoken text. The commentary also raises the concern that children could perform correctly on pretense problems using processes of text…

This response to the commentary on the research reported in this monograph discusses children's understanding of pretending adults' attitudes to pretend situations; the effect of the distinction between fictional and instructional texts on interpreting children's understanding of pretense, when pretense comprehension is seen as analogous to text…

Spontaneous peer interactions of toddlers paired in mixed- or same-age dyads were observed in an effort to see whether the toddlers would adjust their social behavior to the age of their partners. (PCB)

Investigates the effect of disciplinary reasoning on subsequent misbehavior with 2 and 3 year olds. The largest increase in disruptive behavior by age 4 occurred when parents used reasoning frequently without backing it up with punishment. The largest decrease occurred when parents used reasoning frequently but backed it up with punishment when…

Four experiments examined the effects of reenactment on 18-month-olds' event memory. Results indicated that reenacting novel activities in a laboratory playroom improved event memory. Reenactment was more effective after a time delay, and the effects of timing of reenactment were more pronounced after a six-month delay. Reenacting half of the…
