The results indicate that although relational concepts influence the cognitive aptitudes which are reflected in analogy item performance, success in solving analogies does not depend on individual differences in some major aspects of processing relationships. (Author/DEP)

The hypothesis that racial differences in IQ stem from differences in components of executive systems including knowledge base, control processes, and metacognition was investigated. Group differences in metamemory, strategy use, and general knowledge, but not perceptual efficiency, were observed. Metamemory predicted crystallized but not fluid…

The multidimensional structure of verbal comprehension test items was investigated. Empirical evidence was provided to support the theory that item tasks are multivariate-multiordered composites of faceted components: language, contextual knowledge, and cognitive operation. Linear and circular properties of cylindrical manifestation were…

Children aged 6 to 13 years were given verbal and nonverbal fluency tasks and block design subtests of the Wechsler Intelligence Scale for Children-Revised. Results, providing normative data, showed that fluency tasks are age-, but not sex-dependent, and are modestly correlated to one another. (Author/CM)

The predictive power of various cognitive skills at three months of age in terms of later cognitive functioning was examined. Visual habituation and recovery predicted later intellectual functioning at 24 months better than global intelligence or object permanence scores. Changes in cognitive functioning may be a transformation of skills.…

Studied modeling individual latent growth curves of older adults on measures of fluid intelligence by fitting second-order polynomial curves reflecting initial test performance improvement followed by relative stability/drop to the recorded scores of each of 248 subjects. Results suggest substantial plasticity in fluid intelligence of older…

Performance on items in intelligence and achievement tests can be represented in terms of child development and information processes. Research is reviewed on item performance that supports developmental and information processing effects, particularly in children. Some suggestions regarding item development are made. (Author/TJH)

The performance of 136 college students at the University of Western Ontario (Canada) on various parameters of two well-known puzzles was compared with performance on a measure of general intelligence and the Hidden Figures Test. An interpretation of the results is provided by Sternberg's experimental subtheory of intelligence. (SLD)

Howard Gardner's Multiple Intelligence construct is considered from the perspective of its viability in gifted education, especially in comparison with the more traditional Intelligence Quotient-based construct of intelligence. Empirical and theoretical support and contradictory findings are discussed from the literature in cognitive science and…

Three studies involving 16 college students explored cognitive processes reflected by reaction time (RT) and movement time (MT). The hypothesis that correlations of RT and MT with measures of intelligence are due to effects on a common stage of information processing cannot be rejected on the basis of study findings. (SLD)

Whether relations between intelligence test performance and information processing measures depend on individual differences in speed-accuracy preferences rather than capacity limitations and whether the impact of strategic variables changes with increasing age or extraversion was studied with 83 adults ages 50 to 79 years. Results are discussed…

This commentary on a paper by Douglas Detterman and others (EC 604 995), which tested a model assessing basic cognitive abilities in young adults with and without mental retardation, criticizes the paper for drawing conclusions not justified by the empirical results. (JDD)

Proposes that educational researchers consider the implications of a new psychological concept, dysrationalia: the inability to think and behave rationally despite adequate intelligence. The paper argues that researchers need an intuition pump, or prompt, like dysrationalia to aid in reconceptualizing intelligence because I.Q. tests do not measure…

Eight tactile-kinesthetic indices and 27 cognitive-ability and mental-speed measures were administered to 195 college students and community members. Results suggest that tactile-kinesthetic abilities share much with broad visualization and fluid intelligence, little with crystallized intelligence, and differential relationships with speed related…

Cognitive subtest scatter has often been considered to be diagnostically significant. The current study tested the diagnostic validity of four separate operationalizations of WISC-III subtest scatter: (a) range of verbal, performance, and full-scale subtests; (b) variance of verbal, performance, and full-scale subtests; (c) number of subtests…
