Sa. Rose et Jf. Feldman, PREDICTION OF IQ AND SPECIFIC COGNITIVE-ABILITIES AT 11 YEARS FROM INFANCY MEASURES, Developmental psychology, 31(4), 1995, pp. 685-696
Relations between infant information processing and specific cognitive
outcomes at 11 years were examined in a sample of preterms and full-t
erms followed longitudinally (N = 90). Infancy measures, obtained at 7
-months and 1-year, included visual and tactual recognition memory, cr
oss-modal transfer, object permanence, and visual attention; eleven-ye
ar measures included perceptual speed, memory, spatial ability, verbal
ability, and IQ. Two of the infancy measures (7-month visual recognit
ion memory and 1-year cross-modal transfer) predicted 11-year IQ. Most
of the infancy measures were related to perceptual speed, even with I
Q controlled, and were selectively related to other 11-year abilities,
independent of both speed and IQ. These findings reinforce the notion
of cognitive continuity from infancy. Specifically they suggest that
the infancy measures share a common core-perceptual speed-but that som
e of the measures may also tap other conceptually distinct abilities.
