The Raven Advanced Progressive Matrices Test (APM) is a well-known measure of higher order general mental ability. The time to administer the test, 40 to 60 minutes, is sometimes regarded as a drawback. To meet efficiency needs, the APM can be administered as a 30-or 40-minute timed test, or one of two developed short versions could be used. In…

Samples of entering first-grade students were used to examine the predictive validity of the group administered Metropolitan Readiness Test (MRT) and the individually administered Meeting Street School Screening Test (MSSST). The advantage of the latter was found to possibly outweigh the advantage of efficiency in group administration. (Author/GK)

A unidimensional latent trait model was used to test a single-factor hypothesis of the Lawson Classroom Test of Formal Reasoning. The test failed to provide a valid measure of formal reasoning. This was a result of test format which neglected aspects of formal reasoning emphasized by Inhelder and Piaget. (Author/DWH)

Effects of the number of individuals coacting while taking two standardized motor performance tests were examined. Increases in aptitude scores corresponding to increases in group size were predicted based upon the summation hypothesis of social facilitation theory. Results indicated a group size effect.

An alternative way of studying group differences is proposed based on ordering analysis using item hierarchies as a basis of comparison between two groups. Subjects were sets of twins in elementary school. Results showed that blacks and whites and males and females had similar item hierarchies for complex items. (Author/LMO)

A paper-and-pencil test of seven of Inhelder and Piaget's formal operational schemes was developed. Multitrait-multimethod cross-validation procedures indicated that the objective test is a valid and reliable measure. It has the advantage of use in a large group setting without the need for trained clinical interviewers. (Author/PN)

Concurrent validity studies are reported for the School Attitude Measures (SAM), a recently developed school affective assessment procedure. The studies were conducted at three grade levels (5th, 8th, 11th) with a total sample of 153 subjects. Results indicated that the SAM shows promising concurrent validity related to the criterion measures…

The score distributions of the two methods of administration described in the title revealed comparable means, standard deviations, and general shape of distribution. With respect to validity coefficients, no appreciable differences were found. (JKS)
