Experimenter bias effects were experimentally manipulated in a sample of 97 school psychologists scoring 3 subscales (Similarity, Vocabulary, and Comprehension) of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III). First year (n=29), interns (n=42), and experienced (n=26) psychologists were randomly assigned to either a bias or…

Elementary school children were tested individually on their learning of mathematics and on Piagetian tests of concrete operations. Younger children were found to be inferior to older children in their success on learning tasks. (ST)

Purpose of the study was to provide an adequate test of the original Rosenthal and Jacobson teacher expectancy hypothesis by using: (a) equivalent control and experimental groups based on pretest data, and (b) a more suitable test of intelligence. (Authors/CB)

Purpose of study was: (1) to obtain data in a cultural setting concerning the ability of children to conserve weight at the point of transition from primary to secondary education; and (2) to explore the relationship between performance or reasoning tasks of the kind employed in nonverbal psychometric tests and the presence or absence of ability…

Report of an interview with the inventor of the neural efficiency analyzer, reputed to be the first successful culture-free measure of native intelligence. (Author)

A general theoretical rationale is outlined for identifying different kinds of traits, states and function fluctuations of intelligence, providing a basis for developing a set of mathematical procedures which would allow for some separation of traits and states, both seen as patterns of distinct but covarying processes. (Author/MB)

Split-half reliability, test-retest reliability, and concurrent validity, with the WISC as a criterion of the Long and Short Forms of the French Pictorial Test of Intelligence, were compared, using kindergarten and second grade samples. Reliability and validity coefficients for The Short Form did not differ significantly from the Long Form.…
