Current understanding of word-finding (WF) difficulties in children and their underlying language processing deficit is poor. Authors have proposed that different underlying deficits may result in different profiles. The current study aimed to better understand WF difficulties by identifying difficult tasks for children with WF difficulties and by…

This longitudinal study examined the predictive validity of the MacArthur Communicative Developmental Inventories-Short Form (CDI-SF), a parent report questionnaire about children's language development (Fenson, Pethick, Renda, Cox, Dale & Reznick, 2000). Data were first gathered from parents on the CDI-SF vocabulary scores for seventy-six…

Recent work in adult psycholinguistics has demonstrated that activation of semantic representations begins long before phonological processing is complete. This incremental propagation of information across multiple levels of analysis is a hallmark of adult language processing but how does this ability develop? In two experiments, we elicit…

Three investigations of preschool children's comprehension of "younger" and "older" are discussed. Results suggest children focus on height in their initial hypotheses about meanings of the terms, ignoring age or function cues. These and findings about acquisition of antonyms are discussed in terms of recent theorizing about lexical-meaning…

Investigates expression of part-whole semantic relation by children 3 to 12 years old and indicates that older children prefer its use significantly more often. The part-whole semantic relation was also observed to take several linguistic forms, such as partitive, spatial, and possessive. Age, experimental task format, or type of experimental…

Children aged 2 1/2-4 were asked questions containing comparative and superlative forms of adjectives in pairs designated as unmarked/marked or positive/negative. Differences in frequency of correct responses were greater between unmarked/marked pairs than between positive/negative pairs. No evidence appeared for a marking explanation of adjective…

In this experiment, children were given three words (a triplet made up of two nouns and one verb) and were asked to produce an utterance with them. The results were analyzed in terms of word order chosen and age of child. (NCR)

Investigated overextensions in comprehension and production, using the preferential-looking model, in 99 children (ages 1;9 to 2;3) who were asked to find the referent that matched the label they were given in real and anomalous trials. Results confirm that overextensions in production are not diagnostic of children's underlying semantic…
