This is a comparative study on the follow-up samples of Japan-US cross-cultural project concerning maternal influences upon the cognitive development of children. In order to compare the longitudinal generazability of our findings from preschool data, several cognitive measures assesed at 11:0 (Japan) or 12:0 (U.S.) were examined in relation to preschool measures and to early maternal variables. The level of performances were moderately stable throughout preschool and school period in both countries. Most of the present measures were highly correlated with socio-economic status (SES) and parental education in Japan, on the contrary, the correlations of demographic variables with child's measures diminished at school-age level in the U.S. The correlational patterns of early maternal factors with child's outcomes were generally maintained nearly same fashion in both countries, but, the relationships were stronger and tended to continue more persistently in Japan than in the U.S. The mechanisms of early environmental and maternal influences upon later child's cognitive development were discussed in relation to socio-cultural background in the two countries.
