This study was conducted to determine how items of the Stanford-Binet Intelligence Scale, Form L-M, had performed in the 1930's standardization sample in comparison with the 1972 standardization sample. (SB)

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…

Two hundred-sixteen fifth- and sixth-graders were dichotomized on attitude toward school (positive or negative) and randomly assigned to three conditions in which they were instructed that they were about to take either an Intelligence, Achievement, or a Routine test. Results of analysis of variance on Kuhlmann-Anderson scores revealed significant…

Investigated the effect of examiners' ethnicity on the intelligence test performance of Anglo and Mexican-American subjects. On the WISC Vocabulary, Mexican-American subjects scored significantly higher when the test was administered by Mexican-American examiners. (Author)

Timed and untimed scoring methods were employed with five WAIS subtests administered to 40 young and 40 old subjects matched for verbal intelligence. Elimination of bonuses for rapid performance differentially improved the scores of older subjects but did not raise those scores to levels achieved by the young. (Author)

The results of this study show that, below ten years of age, stability in IQ scores from group verbal tests is considerably below that for Stanford-Binet. Non-verbal IQ scores were found to have substantially less stability than verbal IQs. (Author/DEP)

Black students from two cities and Mexican-American students, both male and female, showed small but consistent tendencies to perform better, relative to White groups, on three nontraditional measures: tests of inductive reasoning, spatial scanning, and associative memory. These measures showed somewhat less discrepancy between the groups than did…

Results of a subtest of the Project Access battery, comparing the influence of race, sex and city on inductive reasoning items, are presented. The participating Junior High students represented three racial groups, Black, White, and Mexican Americans, from three cities, Los Angeles, Memphis, and Washington, D. C. The test, entitled Letter Groups,…
