Insufficient research attention has been focused on the development of academic "under"-achievement and motivational beliefs. A longitudinal, person-centered approach was used to identify latent subgroups of growth in the joint development of teacher-reported underachievement and four motivational beliefs (self-concept, task importance,…

Compared the SIT with the WISC-R for a group of intellectually gifted students. Results indicated reduced correlations between the measures. (Author)

Investigated use of revised Slosson Intelligence Test (SIT) for screening public school students (N=131) for giftedness. Found revised SIT intelligence quotient (IQ) mean to be significantly lower than old ratio SIT IQ mean, significantly higher than Wechsler Intelligence Scale for Children-Revised and Stanford-Binet means. Advises caution in…

Scored protocols for 683 gifted students aged six to 12 years using 1961 and 1981 norms of the Slosson Intelligence Test (SIT). Average 1981 norm score was 5.17 points lower than the 1961 norm score. Differences increased with age. Discussed implications for using the SIT for selecting gifted children. (Author/BH)

The Slosson Intelligence Test (revised norms) (SIT) and the WISC-R (Wechsler Intelligence Scale for Children-Revised) were compared. Results provide a moderate degree of support for the concurrent validity of the revised SIT norms, using the WISC-R as the criterion. However, the intelligence quotients on the two tests may not be interchangeable.…

Examined whether Wechsler Intelligence Scale for Children-Revised and the Slosson Intelligence Test could be used interchangeably for identifying gifted students or if the Slosson should be used as a screening instrument in the process of screening and identification in students (N=38) identified as potentially gifted. Results indicated tests…

The capability of the Slosson Intelligence Test and the Otis Lennon Mental Ability Test to predict academic achievement as measured by the Stanford Achievement Test is examined. The results indicated that the Slosson and Otis-Lennon significantly predict Stanford Vocabulary, Reading Comprehension, and Mathematical Concepts subtest scores.…

The Slosson Intelligence Test (SIT) and the Stanford-Binet, Fourth Edition (SBIV) were administered to 95 elementary students referred because of either learning problems or potential giftedness. SIT scores predicted SBIV verbal scores more accurately than composite scores. Overall the SIT predicted SBIV scores better for students with learning…

All variables except the Slosson Intelligence Test were poor predictors of Wechsler Intelligence Scale for Children (Revised) intelligence scores. A moderate correlation was found between verbal and full scale IQ scores and a lower relationship between performance IQ scores on the two scales. Results may be culture specific. (Author/JAC)

Concern about the possible bias of using only verbal assessments for the identification of intellectually gifted students led to an examination of the effect of incorporating nonverbal assessments of intelligence into the identification process. Two nonverbal instruments (Progressive Matrices and Test of Nonverbal Intelligence) were used in…
