Peer reviewedZwiebel, Abraham; Mertens, Donna M. – American Annals of the Deaf, 1985
Results of Snijders-Oomen Nonverbal Intelligence Test for 251 deaf and 101 hearing children in Israel included that (1) factor structure for total deaf group differs from that of hearing group; (2) differences in cognitive structure were evident by age level for deaf; and (3) differences exist between cognitive structures of hearing and deaf…

Peer reviewedFischer, Donald G.; And Others – Perceptual and Motor Skills, 1982
EEG correlates of intellectual functioning in academically handicapped and talented adolescents were investigated. Data from Ertl's Brainwave Analyzer were factor analyzed and used to predict verbal, numerical, reasoning, and spatial abilities and reading and mathematics achievement. Correlational patterns differed by group. Implications for…

Direct linkDolan, Conor V.; Roorda, Willemijn; Wicherts, Jelte M. – Intelligence, 2004
Spearman's hypothesis states that the differences between Blacks and Whites in psychometric IQ are attributable to a fundamental difference in general intelligence ("g"). To investigate this hypothesis, Jensen devised the method of correlated vectors. This method involves calculating the correlation between the factor loadings of the…

Peer reviewedSmith, Glen A.; Stanley, Gordon – Intelligence, 1983
Relationships between intelligence test scores and measures derived from reaction time and perceptual speed procedures were investigated. Only three reaction time measures produced correlations greater than .25 with a general intelligence factor. Test-retest reliability of reaction time measures was low. The reaction time-intelligence relationship…
