In many societies the prevalence of behavioural problems in school-aged children varies by national origin. We examined the association between national origin and behavioural problems in 1 1/2-year-old children. Data on maternal national origin and the Child Behavior Checklist for toddlers (n = 4943) from a population-based cohort in the…

This study examined the relationship among language proficiency, behavior problems, and other areas of development in 36 children (ages 36 to 40 months). A strong association was found between deficiencies in both expressive and receptive language and behavioral difficulties. Specifically, deficits in expressive language at age 2 were more…

A natural language sample of babble and words was obtained for 47 2-year-old children and compared with expressive language scores 5 months later. More than 50 percent of the variance in language outcome test scores was accounted for by rate of word use, rate of vowel babble, and behavior problems. (Author/DB)

The maladaptive behaviors, personality, and language skills of a male whose chromosome analysis showed evidence of mosaicism with karyotype 49,XXXXY and 48,XXXY are described. Research on severity of mental handicap with extra chromosomes, delayed speech development, and discrepancy between verbal and performance intelligence is examined. (JDD)

An interactive model of language intervention that targeted specific vocabulary was evaluated in a study of 16 mothers and their preschool children with language delays. Children in the experimental group used more target words and acquired more symbolic play gestures than those in the control group. Mothers in the experimental group reported a…

Although role or perspective taking has been considered important for the development of mature social thought and behavior, and training for perspective taking has been used to remediate deficient behavior, few studies with either normal or disturbed populations have examined naturally occurring behaviors expected to correlate with…

This article summarizes procedures used in translating technical jargon in the field of behavior therapy to plain English. It lists phrases translated from applied behavior analysis to public education, presents acronyms useful in remembering sequences of steps, and describes two tests to help in decision making in behavior analysis applications.…

The papers comprising this volume discuss research based on an ecobehavioral interaction approach to special education. Six papers are included, which range from a highly conceptual discussion of second language instruction/learning to research concerning interventions to reviews of the research literature. The papers have the following titles and…

This study of teaching methods in language interventions with three preschool children with autism found greater improvements in responding and considerably less disruptive behavior during the natural language (using functional stimuli and natural reinforcers) teaching condition compared to the traditional language condition. (Author/DB)

Two studies examined effects of combinations of setting events on social interactions of seven preschool children with language delays and social interaction deficits. The optimal combination of events for promoting peer interaction included teacher absence from the activity, a limited number and form of materials, and children paired with a…
