Purpose: This study was aimed at determining the role of prosody and situational context in children's understanding of expressive utterances. Which one of these 2 cues will help children grasp the speaker's intention? Do children exhibit a "contextual bias" whereby they ignore prosody, such as the "lexical bias" found in other studies (M. Friend…

Background: Little is known about trajectories of cognitive functioning as individuals with Williams syndrome (WS) move though adulthood. Method: The present study investigated cognitive, linguistic and adaptive functioning in adults with WS aged 19-55 years, using both cross-sectional and longitudinal approaches. Results: Data from the…

Evaluation of questionnaires on the expressive communication skills of 211 individuals with severe mental retardation (including both children and adults in a variety of residential settings) revealed a wide range of communication abilities, with a significantly larger percentage of adults than children communicating at symbolic levels. (Author/DB)

Language sample data from normal subjects (ages 40-79) were collected to determine how normal aging might affect performance on a picture description task, routinely used for assessment of aphasic individuals. Only an increase in the number of paraphasias and a decrease in communication efficiency correlated with increased age. (DB)

This study of the forms and functions of expressive communication produced by 84 children and adults with severe mental retardation found significant differences among participants associated with differences in their communication levels (contact gesture, distal gesture, or symbolic), age (child or adult), and residential status (community home…

Children's use of contextual discrepancy and stressed intonation to interpret literal form and illocutionary function in the use of ironic utterances was examined in two experiments, each using first- and third-grade children and college-age adults. Results suggest a complex relationship between literal form and illocutionary function in…

A study examined the long- and short-term spectral characteristics of speech simultaneously recorded at the ear and at a reference microphone position. Twenty adults and 26 children (ages 2-4) produced 9 short sentences. Children's vocal levels were low in amplitude at both the ear and at the microphone position. (Contains references.) (CR)

Longitudinal change in syntax comprehension and production skill, measured over six years, was modeled in 31 individuals (ages 5-20) with Down syndrome. The best fitting Hierarchical Linear Modeling model of comprehension uses age and visual and auditory short-term memory as predictors of initial status, and age for growth trajectory. (Contains…

Connected speech of 134 healthy, Canadian French-speaking adults, grouped according to age and education level, was analyzed using an aphasia battery. Results demonstrated that older subjects with less education produced fewer content units and were less efficient in transmitting lexico-semantic information. Effects of age and education level on…
