Category-based induction is a hallmark of mature cognition; however, little is known about its origins. This study evaluated the hypothesis that category-based induction is related to semantic development. Computational studies suggest that early on there is little differentiation among concepts, but learning and development lead to increased…

Children's sensitivity to the quality of epistemic reasons and their selective trust in the more reasonable of 2 informants was investigated in 2 experiments. Three-, 4-, and 5-year-old children (N = 90) were presented with speakers who stated different kinds of evidence for what they believed. Experiment 1 showed that children of all age groups…

Semantic and cognitive factors governing passive-voice comprehension were studied in kindergarten, first-, and second-grade children. (ST)

Two predictions based on H. Clark's and E. Clark's hypotheses of the acquisition of word meanings were tested: (1) when learning words which have both spatial and temporal meanings, children will understand the spatial meanings first, and (2) children understand the positive member of an antonym word pair before they understand the negative…

Tests the hypothesis that semantic memory changes with age such that concepts become more strongly associated with their superordinate classes than with their exemplars. The Stroop color-naming technique was employed with 48 children 8 through 12 years of age to measure the degree of semantic activation between concepts in memory. (Author)

Preschool children were tested for their understanding of the use of definite and indefinite articles in 2 kinds of story-telling tasks. (ST)

Conclusion drawn is that bilinguals, brought up in a one-person, one-language home environment, reach a stage in semantic development some 2-3 years earlier than their unilingual peers. (Author/CB)

In three experiments, three- and four-and-a-half-year-old preschool children were tested on free and cued recall tasks in which semantic and contextual cues were manipulated. When context and target items were integrated experimentally at presentation, unrelated context cues improved recall. A developmental increase in the effectiveness of…

Two studies addressed whether preschoolers consider speakers' knowledge states when establishing initial word-referent links. Children showed better learning from a speaker knowledgeable of novel words' referents than from an ignorant speaker. Four-year-olds, but not 3-year-olds, learned words better when speaker said the object was made by…

Presents a study which assessed preschool children's understanding of "front,""back," and "side" through a variety of tasks. A developmental sequence is defined. (ED)

Japanese and American children participated in a free word association experiment. Results indicated that culture was influential in the formation of language. (ST)

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)
