Three hundred kindergarten, first and second grade children from Beijing, C
hina were given the Boehm Test of Basic Concepts-Revised (BTBC-R) at the en
d of the school year. Their performance was compared with that of American
children from the standardization sample of BTBC-R. This study explores two
questions: (1) Will lexical diversity and morphological complexity affect
the rate of acquisition of the basic relational concepts between children w
ho speak distinctly different languages? and (2) to what extent do conceptu
al factors interact with linguistic differences in children's development o
f basic relational concepts? Results showed that Chinese children acquired
significantly more basic relational concepts than their American peers at b
oth first and second grades did but not at kindergarten. This difference in
acquisition is discussed in terms of the characteristics of the two langua
ges. Nonlinguistic factors are discussed in terms of cultural and parental
influences on young children's conceptual development.
