Data suggest that young infants (110-130 days old) process distinctive features of objects that continuously change orientation. The importance of these findings for theories of cognitive and perceptual development of infants is discussed. (Author/DB)

Explores longstanding inconsistencies in Piaget's account of development of spatial representation and perspective-taking. Examines Piaget's early writings and the findings of the original "three mountains" experiment. Concludes that Piaget's alternative theory is compatible with contemporary thinking and is important as a contributory…

Examines the fallacies about the nature of abilities and learning and about the interaction between sense modalities which follow from the dichotomy in relation to explanations of spatial development in the blind. Suggests that interactions between cognitive and perceptual factors need to be considered to explain more adequately effects of sensory…

Factor analysis of correlations among the measures of recall clustering, free sorting, and recognition errors revealed significant convergent validity for consistent use of a semantic perceptual organization strategy in the three tasks. Ten-year-old, adult, and elderly adult subjects relied on a semantic strategy; four- and six-year-olds encoded…

Studied the relationship of joint mother-child planning before and during tasks, and the ability of four and eight year olds to plan on their own. Found that older children planned more effectively, especially during tasks, and that mothers of younger children concerned themselves with task procedures rather than strategy. (MDM)

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…
