Although fluency and automaticity of handwriting have been recognized as important research topics for 30 years, empirical data on respective developmental courses among typically developing children as well as clinical samples have remained very limited. To fill this gap, this study investigates the development of handwriting automaticity…

Reports results from a controlled longitudinal study of 141 Swedish children with syndromes of perceptual, motor, and attentional deficits, giving special reference to generalized hyperkinesis. (MP)

Infants were tested at 5, 8, and 13 months of age for numerosity perception. Subjects observed displayed figures on a screen moving at constant speed with irregular trajectories and occasional occlusions. Results demonstrated that discrimination of units, and not of characteristic patterns, underlies numerosity perception. (BC)

Children were tested at ages four and six for recall of clusterable objects under play and sort conditions. Conceptual clustering predicted recall performance of six-year olds in both conditions and of four-year olds in the sort condition. The stability of memory variables was low with the exception of free recall. (BC)

Over half the world's population speaks a tone language, yet infant speech perception research has typically focused on consonants and vowels. Very young infants can discriminate a wide range of native and nonnative consonants and vowels, and then in a process of "perceptual reorganization" over the 1st year, discrimination of most…

The development of and relationship between early language, symbolic play, sensorimotor skills, and social development were examined in a longitudinal study conducted in Japan with two young autistic males who were observed from the approximate ages of 2 to 4 years in clinic, day care, and home settings. One child acquired speech; the other did…

This study attempts to identify potential school problems in preschool children in order to facilitate the provision of relevant information for systematic screening and early guidance. Data from the first 14 months (to the end of the preschool period) of a longitudinal study extending from 4 1/2 years of age to the end of second grade are…

The third Fenno-Hungarian Conference on Developmental Psychology covered four main concepts: the historical roots and development of social competence through three generations, parent-child interaction, parenthood, and the development of socio-cognitive competence through childhood and adolescence. A series of papers was presented addressing the…
