Children learn the words of their native language(s) from interactions with their caregivers. Although previous research has found that the language children hear during those interactions predicts vocabulary outcomes, few studies have investigated how qualitative features of social interactions work together to affect children's vocabulary…

The predictive ability of early consonant inventory and intentional communication on later expressive language was examined in 36 boys with fragile X syndrome (FXS). Autism symptom severity was included as a potential moderator. Participants were visited in their homes twice over a 6-year period, and mother-child interactions were videotaped,…

Introduction: Children and young adults with Down syndrome can demonstrate increased behavior problems compared to their typically developing peers through childhood and adolescence. Though current tools measure behavior problems in persons with intellectual disabilities, they do not capture all the behavioral problems that can occur in…

This study aimed to investigate the relationships between abilities to initiate and respond to joint attention and symptoms of autism that have, and have not, been theoretically linked to joint attention. Participants were 51 boys and five girls with autistic disorder, aged between 2 years and 6 years 5 months. Measures of joint attention…

This review looks at the impact of word finding deficits, psycholinguistic considerations in naming (including relevant intrinsic and extrinsic variables), behaviors indicative of word finding difficulty, screening for word finding disorders in the classroom, direct assessment (both formal and informal), individual differences, and word retrieval…

Research examining autistic symptoms in Angelman syndrome (AS) is limited. The goal of this study was to further characterize the nature of stereotyped behaviors, social interaction deficits, and developmental disturbances in individuals with AS. Parents of 248 individuals between the ages of 3 and 22 completed a survey of autistic symptomatology…

Adults (n=20) who interacted with small groups of preschoolers, including a child with expressive language disorder (ELD), evaluated the ELD child differentially depending on awareness of the child's ELD label. Adults unaware of the label ranked the ELD child as less likable and less productive and predicted less academic competence. Aware adults…

Addressing methodological limitations, Study One compared parent-child interactions of normal and language-delayed children; Study Two investigated whether mothers adjust the length of their utterances to the child's ability to comprehend or to produce language; Study Three probed interactional variables associated with variations in the…

Apparently positive behaviors, such as praise, help-giving and pity, may indicate low estimation of ability to the student, and blame, relative neglect, and anger may be perceived by the recipient as high estimations of ability. These behaviors influence recipient self-perception and determine expectations, affective reactions and performance.…

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…

Studied one aspect of communication competency: how people express emotions through verbal behavior. Found, among other conclusions, that references to unpleasant emotions outnumber references to pleasant emotions almost two to one. (PD)
