The California Psychological Inventory (CPI), the Slosson Intelligence Test (SIT), and the Shipley-Institute of Living Scale (SILS) were administered to undergraduates. The Intellectual Efficiency scale scores were correlated .52 with the SIT scores and .39 with the SILS scores. The SIT and SILS were correlated .49. (Author/GK)

The mean IQ on the Slosson Intelligence Test (SIT) was substantially higher than expected based on the earlier Peabody Picture Vocabulary Test (PPVT) scores. Sampling error and examiner error were excluded as explanations. Results suggest that the PPVT and SIT yield different scores and lack comparability. (Author)

This study was concerned with determining the validity of the Slosson Intelligence Test (SIT) using the Stanford-Binet Intelligence Scale (S-B), Form L-M as the validity criterion. The sample consisted of 724 students enrolled in 10 public school systems in northeastern Massachusetts. Using the Pearson-Product Moment formula a coefficient of…

This critical evaluation of the Slosson Intelligence Test (SIT) determined that the test items are 30 years old, scores are derived from a nonrepresentative norm group, and scores are not interchangeable with other intelligence measures. The paper concludes that the SIT is unsuited for educational decision-making purposes, including screening,…

Critiques the 1990 revision of the Slosson Intelligence Test. The SIT-R is an untimed, individually administered screening instrument that assesses the mental ability of children and adults. Many of the problems with the original version have been addressed in the revised version, but with varying success. (LKS)
