K-Abc Score Patterns of Sioux Children: Mental Processing Styles, Effects of School Attendance, and Relationship Between Raw Scores and Age

Abstract

This study examined several relationships with and between scores on the Kaufman Assessment Battery for Children (K-ABC) and a group of Sioux children (N = 48) living in a rural reservation area. The specific relationships that were examined included the relationship among raw scores on the K-ABC and age; mental processing patterns of the K-ABC Simultaneous, Sequential, and Achievement scores; and the effects of school attendance on K-ABC scores. The study sample was found to have a significantly stronger and less variable relationship between age and K-ABC raw scores. Consistent with some previous research, the simultaneous Processing scores for this group were found to be significantly higher than either their Sequential Processing or Achievement. Additionally, school attendance patterns appeared to have very limited and nonsignificant effects on the subjects' K-ABC performances. Findings of this study are discussed in terms of the relationship to previous studies that used the K-ABC with American-Indian children. Finally, implications of this study are discussed.
