We investigate the effects of age-related factors and formal instruction on the development of reading-related skills in children aged 4 and 7 years. Age effects were determined by comparing two groups of children at the onset of formal schooling; one aged 7 (later-schooled) and one aged 4 (earlier-schooled). Schooling effects were measured by…

In three experiments, adults and 30-month-old children (1) selected a novel object as the referent for a novel term; (2) extended the new word to another exemplar; and (3) allowed the new word to preempt another novel label from applying to the just-named object. (BC)

Discusses the interaction of age and sex factors on consistency of recognition of 71 Peabody Picture Vocabulary Test pictures by preschool children. (TO)

Examined digit and word dichotic listening in children in kindergarten and again one year later. Found that in the second digit test, between-ears performance difference decreased; overall performance increased. Between-ear differences across the two word tests were not significant, but overall performance improved over time. Age changes in the…

Examines whether age-related differences would be observed between young children and adults for discrimination of synthesized, five-format consonant-vowel syllables that differed in voicing onset time of the initial consonants. (HOD)

Investigations of the effects of visual imagery and pictorial stimuli on young children's oral prose learning indicated: (1) age differences affect the ability to profit from self-generated imagery; (2) experimenter-provided cues help to generate imagery; and (3) the type of cue provided relates to the kind of information recalled.

The relationship of age and developmental differences to modeling and motor skill development were examined. Comparisons of the observational learning patterns of four- and five-year-old children and of seven- and eight-year-olds suggest that their physical and cognitive capacities call for different instructional strategies. (Author/PP)

Investigated children's understanding of meaning of the cognitive verb "know" (as defined by an abstractness and conceptual difficulty hierarchy). Found that knowledge increased with development, and low levels of meaning were mastered before high levels, and more rapidly. Understanding in audio-taped stories was more difficult than in video-taped…

A 7-month longitudinal study of 20 2- and 3-year-old children shows that children at an early age already know that counting words each refer to a distinct numerosity, although they do not know to which numerosity. It takes children a long time to learn the latter. (SLD)

Thirty-seven second, 41 fourth, and 46 sixth graders were tested on low-level subcomponents of reading efficiency and high-level text comprehension to assess the relationship between the two parameters. High-level comprehension does not depend on efficiency of lexical access processes, but verbal memory span is important in high-level…
