The purpose of the present studies was to test the hypothesis that the psychometric characteristics of ability scales may be significantly distorted if one accounts for emotional factors during test taking. Specifically, the present studies evaluate the effects of anxiety and motivation on the item difficulties of the Rasch model. In Study 1, the…

The scores of 537 14-year-old students in Nigeria on the Raven Progressive Matrices were correlated with their scores on an achievement test, to provide an estimate of the predictive validity of the Raven. Results indicated low validity for this usage. (Author/JKS)

One hundred undergraduate arts students were tested on all the scales of Wechsler Adult Intelligence Scales (WAIS) and the Differential Aptitude Tests. Varimax solutions were extracted on WAIS scores under four analytic conditions. No progressive increment in the WAIS communalities was marked as the marker variables increased. (Author/RL)

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…

Factor analysis of an administration of the Raven Progressive Matrices Test to children in grades 1, 2, and 3 revealed three orthogonal factors interpreted as (1) concrete and abstract reasoning, (2) continuous and discrete pattern completion, and (3) pattern completion through disclosure. Results are discussed in several contexts. (RC)

Canadian undergraduate students were administered the British general ability test, AH2, along with a multiple-choice vocabulary test and the Standard Progressive Matrices, a nonverbal ability test. Scores were compared with British norms and intercorrelated with those of the other two tests. Correlations with the other ability tests were low.…

Bilingual Navajo adolescents aged 14-16 were administered the Raven Standard Progressive Matrices (RSPM) and Comprehensive Tests of Basic Skills (CTBS). Correlations were moderate and were higher for females than for males. Norms were established for adolescent Navajos on the RSPM, a nonverbal test of intelligence and visual reasoning. (Author/GDC)

The Raven Coloured Progressive Matrices and a Piagetian battery were administered to a sample of hearing-impaired elementary school children under six different conditions. Results indicated that scores varied as a function of the degree and type of feedback or elaboration. (JKS)
