Investigated whether group differences between immigrants and majority group members are best described as Jensen effects or as cultural effects and studied the bias of culture-reduced tests and culture-loaded tests.

Spearman's hypothesis states that the differences between Blacks and Whites in psychometric IQ are attributable to a fundamental difference in general intelligence ("g").

Eighty gifted and 80 nongifted African American, Latino, Filipino, and white elementary school students were evaluated through information processing tasks.

Intelligence tests were administered twice to 426 members of 93 transracial adoptive families, once when the adopted children's ages averaged 7 years and again when they averaged 17 years. Correlations suggest that influences on intellectual development in this sample of black and interracial adoptees reared in white families are similar to those…
