The experiments described in the lead articles by Kowalski and Zimiles and by O'Hanlon and Roberson examine factors that lead to color term acquisition. These experiments touch on the debate regarding the relative contributions of language and concepts in word learning. In this reflection, we examine how conclusions concerning the debate depend…

Children aged 3, 6, 9 and 12 years were asked to name and sort 25 different drinking vessels. Results showed three stages: (1) they ove rextend the term "cup"; (2) they focus only on certain perceptual properties; (3) they show growing awareness of functional properties and hence the vagueness of the boundary.

Examination of object word learning and use in beginning (vocabulary of less than 50 words) and advanced (vocabulary of more than 50 words) infant speakers indicated that both groups formed concepts, learned, and generalized words for the to-be-learned objects. Advanced speakers learned more words and concepts and engaged in broader generalization…

The acquisition of spatial terms in the language development of young children is examined. Two primary theories of word meaning and concept acquisition are reviewed, followed by a summary of current developmental research on spatial terms and factors influencing acquisition. Finally, guidelines for the assessment and teaching of spatial terms are…

Eighteen children (mean age 10.2 years) with mild mental retardation were pretested on a variety of measures and then instructed on Piagetian concepts twice per week for 4 months via a learning set technique. When posttested at semester's end, the children had, with few exceptions, mastered the concepts and made significant gains on the Peabody…

This study investigated (1) the order of acquisition of related temporal and spatial terms, (2) the application of temporal and spatial terms and (3) the relationship between the application of temporal and spatial terms and performance on cognitive measures of temporal and spatial ordering. Children 3 to 5 years of age were tested on four…

Three studies tested the hypothesis that children's difficulty acquiring dimensional adjectives, such as big and little, is a consequence of how these words are used by adults. Findings indicated that children easily acquired novel dimension words when such words were used in a strictly comparative fashion, but had difficulty when also exposed to…

Twenty-four 12- to 19-month-old children were studied to examine the cognitive basis for the emergence of verbs. Substantial increases in verb comprehension across contexts, abstract cognition, and the ability to engage in symbolic action were observed, suggesting a relationship between underlying cognitive development and increased verb…

Investigates the role of intraverbal learning (a process through which semantic knowledge is acquired from purely linguistic information) in preschool children's acquisition of semantic concepts. Shows that the relative effectiveness of pictorial and intraverbal information depends on the child's age, the type of information supplied, and the…

The frequency and type of inappropriate word extensions (i.e., use of ball for moon) in the spontaneous speech of nine young language disordered children (2.8 to 3.4 years old) were studied. The percentage of inappropriate word extensions of these children was comparable to that of normal children at the same level of linguistic development.…

This paper studies aspects of the conceptual basis for language acquisition, with a focus on the perceptual-cognitive skills used to assign meanings to words. A first assumption is that the correspondence between adult and child perceptual features allows for early communication. Apparently, in the first year, naming is characterized by…

Cognitive development research can be applied to the learning of a second language, resulting in a view of language learning as the acquisition and development of expertise. From this framework, two processes are viewed from within this framework for learners of English: learning vocabulary and learning discourse and story. (Contains 10…
