A major concern in recent research is whether perceptual or functional information is of primary importance in children's early word meanings. In the study described here, artificial objects were used so that form and function could be independently manipulated. There were 57 subjects, ranging in age from 2.5 years to adulthood. The subjects were…

Two experiments used the preferential looking task to assess early word comprehension in 12- to 24-month olds. Results indicated that when target stimuli were named, 12-month olds displayed an increase in target looking for typical--but not atypical--targets, whereas 18- and 24-month olds displayed increases for both.

Compares two types of semantic development (the acquisition of disappearance words and success-failure words) to performance on two types of cognitive tasks (object-permanence and means-ends tasks) among infants. (HOD)

Children may be able to gain partial information about the meaning of a word from clues, such as how it is used in a sentence and what words it is contrasted with. This strategy, known as "fast mapping," may provide a very useful first step in language learning. One question which arises from studies of fast mapping is whether fast…

The three basic language learning models are the rote-memory model (prescriptive), the abilities model (behavioristic), and the critical age model. If this last model, a deterministic one based on observable facts about the human condition, becomes as popular in American schools as it is in British schools, language will become an important aspect…

Questions whether children's use of language indicates they (1) understand temporal sequence, (2) distinguish goal-oriented from nongoal-oriented activities, and (3) prefer discussing the aspect of events prior to the time of events. Also investigates whether findings for past and future conditions are parallel. (Author/DB)

Examined three-year-old children's ability to generalize novel words to new instances. Suggested that children's similarity judgments and feature selection in name generalization are guided by nonstrategic attentional processes that are minimally influenced by new conceptual information. Proposed that these findings may explain the extraordinary…

Describes three experiments that tested autistic children's nonverbal and verbal categorization abilities. Concludes that autistic children do not suffer a specific cognitive deficit in ability to categorize and form abstract concepts. (HOD)

Two experiments examined preschoolers' and adults' relative reliance on visual and verbal information in identification of animals and machines. Findings include both children and adults can use either visual or verbal cues in categorization, and a stricter definition is used in identifying animals. Results suggest that a perceptual to conceptual…

Describes two studies investigating the development of recursive thinking in 60 Dutch children five, seven, and nine years of age. The first study replicated earlier research employing a verbal production procedure. The second study used verbal comprehension procedures and concluded that development appears two years earlier than indicated by the…

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…

From the standpoint of transformational grammar, this experimental work evaluates the extent to which children choose or fail to generalize their rules for the placement of the negative particles "not" and "n't." The subjects were eight three- and four-year-olds of middle-class background who had been producing sentences with…

The role of language in conservation tasks and the development of the concept of conservation of quantity in young children are investigated in this study. A total of 50 children, aged 3.0 to 4.7 years, were divided into three groups according to age with a large number clustered around age 4.0 years. Children were randomly assigned to one of two…

A model for developing instructional analogies was used to produce experimental treatments that included text from a high school biology textbook to which was added extended verbal analogies written by the researcher linking each of two biology concepts to analogous familiar concepts. The control treatment was text from the biology textbook…

This paper reports on an experiment undertaken to delineate more clearly the relationship between the naming process in children and certain aspects of the environment which may play a role in that process. The investigation concerned the effect of manipulation and of object novelty on naming. Sixteen children, ten girls and six boys, ranging in…
