Near Identity of Cognitive Structure in Two Ethnic Groups

Abstract

As part of a large-scale family study in Hawaii, Americans of either Japanese or European ancestry were administered a battery of 15 cognitive tests. Principal component analyses (varimax rotations) yielded the same four major cognitive factors for each of the two ethnic groups, and these factors are defined by strikingly similar factor loadings.

Genetic and environmental influences on the Verbal-Perceptual-Image Rotation (VPR) model of the structure of mental abilities in the Minnesota study of twins reared apart

“…In MISTRA, the Raven was presented via slides in a psychophysiology laboratory (Lykken, 1982), and administered on an untimed basis. DeFries et al (1974) reported internal consistency and retest reliabilities for the HB tests ranging from .58 for Immediate Visual Memory to .96 for Vocabulary.…”

Sex differences in mental ability: A proposed means to link them to brain structure and function

“…In MISTRA, the Raven was presented via slides (Lykken, 1982), and administered on an untimed basis. DeFries et al (1974) reported retest and internal consistency reliabilities for the tests ranging from .58 for Immediate Visual Memory to .96 for Vocabulary.…”

“…The HB was developed to assess familial resemblance in cognitive ability in the Hawaii Family Study of Cognition (DeFries et al, 1974;Kuse, 1977). Two tests in this battery (Number Comparison and Social Perception) were not administered, again to avoid duplication of tasks.…”
