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…

Children at a very young age are ready and willing to discover the world through tasting, smelling, hearing, touching, and seeing. As they emerge into an awesome world of sounds, touches, movements, lights, tastes and smells from birth, infants must learn to regulate this overwhelming amount of sensory stimulation. At first, an innate sensory…

Changes in distress and problem behaviors of 38 infants/toddlers were examined after children transitioned from familiar to new classrooms to look at effects of non-continuity of caregiver. Child's age, classroom quality, teacher sensitivity, and transitioning with a peer were examined as possible mediators. Results suggest that transitions were…

In 3 studies, young children were tested for their understanding of pretend actions. In Studies 1 and 2, pairs of superficially similar behaviors were presented to 26- and 36-month-old children in an imitation game. In one case the behavior was marked as trying (signs of effort), and in the other case as pretending (signs of playfulness).…

Effects of negative input for 13 categories of grammatical error were assessed in a longitudinal study of naturalistic adult-child discourse. Two-hour samples of conversational interaction were obtained at two points in time, separated by a lag of 12 weeks, for 12 children (mean age 2;0 at the start). The data were interpreted within the framework…

Auxiliary syntax is recognized to be one of the more complex aspects of language that children must acquire. However, there is much disagreement among researchers concerning children's early understanding of auxiliaries, with some researchers advocating a relatively abstract grammar as the basis for auxiliary syntax, while others view the…

One of the most influential recent accounts of pronoun case-marking errors in young children's speech is Schutze & Wexler's (1996) Agreement/Tense Omission Model (ATOM). The ATOM predicts that the rate of agreeing verbs with non-nominative subjects will be so low that such errors can be reasonably disregarded as noise in the data. The present…

This study examined California's efforts to foster preservice preparation of early intervention assistants through a certificate program offered by community colleges, the Community College Personnel Preparation Project. Community colleges enrolled in the project must meet a series of requirements, including infusing early intervention assistant…

"Child Care Health Connections" is a bimonthly newsletter published by the California Childcare Health Program (CCHP), a community-based program of the University of California, San Francisco School of Nursing, Department of Family Health Care Nursing. The goals of the newsletter are to promote and support a healthy and safe environment…

By law each state is required to ensure that all substantiated cases of maltreated infants and toddlers are referred to Part C early intervention services. In reality, many children may not be receiving the child development services they need. Researchers have known for some time that children who have been abused are at greater risk for…

This study investigated the influence of the intervention process on the effectiveness of a program aimed at promoting positive parenting. The study involved a homogeneous intervention sample (N = 120) of mothers and their 1-, 2-, or 3-year-old children screened for high levels of externalizing problems. The alliance between mother and intervener,…

We investigated humor as a context for learning about abstraction and disbelief. More specifically, we investigated how parents support humor understanding during book sharing with their toddlers. In Study 1, a corpus analysis revealed that in books aimed at 1- to 2-year-olds, humor is found more often than other forms of doing the wrong thing…

Background: Individuals with autism spectrum disorders (ASDs) show variability in their sensory behaviors. In this study we identified clusters of toddlers with ASDs who shared sensory profiles and examined differences in affective symptoms across these clusters. Method: Using cluster analysis 170 toddlers with ASDs were grouped based on parent…
