Examined the relationship between infants' early verbal imitation, when the ability to copy behaviors first emerges, and their lexical development during the second year of life. Twenty infants were examined longitudinally at ages 10, 13, 17, and 21 months. Suggests that infants' early imitation of words not in their repertoires predicts and may…

Investigated developmental change in symbolic representational ability by examining infants' imitation of vocalizations, words, visible motor actions, and nonvisible motor behaviors at ages 10, 13, 17, and 21 months. Results revealed a pattern of increasing imitation, supporting the view that a domain-independent representational capacity develops…

Data from 48 infants revealed (1) that infants aged 1;2-2;3 failed to establish a stable word-object link even in follow-in labeling and (2) that only infants aged 1;6-1;7 could identify the correct referent during discrepant labeling. During the period between 1;2-1;7 infants are becoming increasingly adept at acquiring new labels under minimal…

This study of 52 learning-disabled children, aged 8-13, found that direct feedback and practice improved metaphor interpretation. The approach was highly successful in teaching students to generalize concrete concepts to abstract ones. Further descriptive analyses indicated that grade and reading levels of subjects correlated with metaphor…

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…

Two experiments examined toddlers' noun vocabularies and interpretations of names for solid and non-solid items. Results indicated that one side of the solidity-syntax-category organization mapping was favored. Seventeen- to 33-month olds do not systematically generalize names for solid things by shape similarity until they already know many…

Investigated the nature and representation of vocabulary instruction in the teachers' edition of social studies textbooks for grades four through eight. Found that although publishers realized the importance of vocabulary, they continued to include vocabulary activities that represent traditional rather than higher order ideas about how to support…

This study describes the vocal development of infants born with very low birth weights (VLBW). Samples of vocalizations were recorded from three groups of infants when they were 8, 12 and 18 months of age: preterm VLBW infants with bronchopulmonary dysplasia (BPD), preterm VLBW infants without BPD, and healthy full-term infants. Infants with BPD…

This study investigated the effect of day care attendance on the receptive and expressive language development of nine 4-year-old children. Five children who had 2 years of day care experience comprised a day care group. A home-reared group was composed of four children who had 3 months of day care experience. Children's receptive language ability…

A major purpose of the research reported here is to determine whether or not children of minority backgrounds possess the ability to tell stories and verbalize in narrative form at age 3 and 4. Narratives and speech play were collected over a 9-month period in two Headstart classes in Honolulu (Hawaii). The children, most of mixed backgrounds,…

The phenomenon of limited bilingual language proficiency is reported to have negative academic and/or cognitive consequences, especially among Mexican-American minority language students. Where such students have been diagnosed, fears of concomitant congitive retardation are also expressed. Research was undertaken to understand the phenomenon…

The importance of the role of meaningfulness as a learning variable is discussed. (DEP)

Investigated the premise that differences in developmental patterns as recorded on a scored biodata form are related to differences in verbal behavior as evidenced in six protocols derived from responses to the Kent-Rosanoff Word Association Test. Subjects were 110 female college students. (SDH)

While previous studies investigating sex differences in the growth of academic abilities have been inconsistent in their conclusions, sex differences have often been reported, particularly in the areas of verbal and mathematical achievement. Results from several longitudinal studies have suggested that these measured differences in achievement are…

The concept of consciousness played a central role in Vygotsky's research and theory. Unfortunately, with the advent of behaviorism, consciousness fell into disfavor. One of the major obstacles in studying consciousness is that there is no single acceptable definition of the term. Various researchers have dealt with five different aspects of…
