| Research Abstract |
The purpose of the present study was to examine whether neurodevelopmental status and visuo-cognitive function during the first year of life were significantly correlated with intellectual function later in childhood or not. The results were as follows : (1)Three-to 10-month-old infant's performances of novelty preference in paired-comparison paradigm (preferential looking) appeared to be curvilinearly related (inverted U-form) with the scores on the Simultaneous Processing Scale of the K-ABC in 3 years later. (2)Both the Bayley Infant Neurodevelopmental Screener and the Revised edition of Japanese Denver Developmental Screening Test predicted no more than 1 % of the variance in standard scores of the K-ABC later in childhood. (3)Proprioceptive sensitivity and stranger anxiety observed in infancy were strongly correlated with self-recognition ability in one-half year after. We concluded that the lack of prediction found in this study was interpreted as evidence for a fundamental discontinuity in intelligence.
