Purpose: The authors examined (a) whether dose frequency of milieu communication teaching (MCT) affects children's canonical syllabic communication and (b) whether the relation between early canonical syllabic communication and later spoken vocabulary is mediated by parental linguistic mapping in children with intellectual disabilities (ID).…

This study examined the relationship between prelinquistic vocalization and expressive vocabulary one year later in 58 toddlers (ages 17- to 34-months old). Rate of vocalizations, rate of vocalizations with consonants, and rate of vocalizations used interactively were all positively related to later expressive vocabulary. (Author/DB)

This study used an intact group comparison to examine attention following in 34 children aged 2 years diagnosed with autism spectrum disorder (ASD) matched pairwise for vocabulary comprehension with a group of typically developing toddlers. For both groups of children, the presence of verbal labels during a referential task increased attention to…

This study examined whether maternal responsivity would predict the extent to which prelinguistic milieu teaching (PMT) facilitated generalized intentional communication better than a contrast small-group treatment with 58 children (ages 17 to 36 months) with developmental disabilities. If mothers were relatively responsive before treatment, PMT…

Fifty-eight prelinguistic children with developmental disabilities and their mothers participated in an experimental test of whether intentional communication elicits maternal responses purported to facilitate language development. Results indicated that treatment effects on maternal responses varied by pre-treatment maternal education level and…

Thirty-five children diagnosed with autism or pervasive developmental disorders at age 2 were re-evaluated 2 years later for factors related to spoken language development including child variables and environmental variables. After controlling for age 2 language skills, the only significant predictors of age 4 language skills were motor imitation…

Analysis of mothers' pragmatic language use and children's language levels during free play sessions suggested that a mother-driven, direct influence model may be inappropriate for many mother speech-child language development relationships and points to the feasibility of child- and mother-driven explanatory models for indirect relationships.…

Four toddlers with mental retardation were studied in the context of a multiple baseline across subjects design. Results supported the use of a modified version of milieu teaching to increase intentional requesting by these children. Increased intentional requesting was generalized to interactions with mothers. (Author/DB)

Receptive language, prelinguistic communication, maternal responses, vocabulary level, and expressive language were measured at six-month intervals for 58 young children with disabilities or developmental delays and their primary caretakers. Results supported the importance of caregivers responding differentially to preintentional and intentional…

This study evaluated the effectiveness of Prelinguistic Milieu Teaching for toddlers (n=39) with intellectual disabilities and responsivity education for their parents as a means of facilitating children's communication and language production skills. Comparison of parent child pairs receiving or not receiving the intervention found the…

A study involving 58 children (17 to 36 months) with developmental disabilities in the prelinguistic period of development and their mothers found that the relationship between intentional communication and later language was, in part, due to covarying relationships with maternal responsivity. (Author/CR)

A study tested the relationship between prelinguistic pragmatic functions and later expressive vocabulary of 58 toddlers with mild to moderate developmental delays. Results indicate that rate of joint attention and rate of communication were statistically significant predictors of later expressive vocabulary. Rate of behavior regulation was not a…
