This speech reports an experiment on memory and verbal ability. The study notes that in previous research, verbal ability has been found to correlate with sensitivity to order, an important component of intelligence. This relationship may be due largely to the greater word store of high verbal scorers. The author's experimental hypothesis is that…

Black-and-white or color versions of four types of illustrations (simple line, detailed line, photograph of model, photograph of specimen) of the heart were used to complement oral instruction in a study to determine which type of visualization would be most effective in facilitating the achievement of students of different IQ levels.

Past validity research involving the Leiter International Performance Scale and the Arthur Adaptation of the Leiter International Performance Scale is reviewed, particularly as it relates to evaluating intelligence of hearing impaired children. (Author)

A follow-up investigation of 68 children 10 years of age who had been assessed originally at ages 4, 8, 13, and 27 months, did not reveal strong relations between infant variables (such as attentiveness, vocal excitability, irritability, or activity) and reflection-impulsivity, intelligence quotient, or reading ability at age 10. (JMB)

Compared intrachild variability of five-year-old children on the Primary Mental Abilities Test when subjects reached their fifth birthday after completing at least two years of preschool enrichment. Conclusions, although qualified on the basis of limited sample size, revealed wider intrachild variability with minority children. (Author)

The role of mental age (MA) and visual-perceptual ability in number concept development was examined with 48 nonretarded and retarded children from regular school settings. (Author)

The response to the question "What next?" is a synthesis--a combination of philosophical, psychological, and linguistic scholarship with electronic and computational technologies, under the pressure of commercial requirements for improved man-computer communication. (Author/VT)

This study of young men from two-child families shows that birth-order effect and level of ability were not influenced by length of interval between firstborn and secondborn. (MP)

A reevaluation of a number of experiments suggests that normal and retarded persons differ on short-term memory tasks from the time of initial stimulus exposure. The hypothesis that memory differences are due to differential encoding as a result of more adequate rehearsal by the normal subjects is unacceptable. (Author/BW)

Correlations with Binet IQ in the ITPA normative sample were corrected for restricted intelligence range. The corrected correlation for the Psycholinguistic Quotient is as high as that between the WISC and the Binet, a finding that raises a serious question about the construct validity of the ITPA. (Author)

Regular booklet and puzzle forms of the Raven Coloured Progressive Matrices were administered to 70 deaf elementary students to determine the effects of testing-the-limits procedure. (Author/CL)

The Lorge-Thorndike Intelligence Test was found to be effective in screening 275 fifth grade students for learning disabilities. (CL)

Hirschi and Hindelang's (1977) causal model in which IQ is linked to delinquency by a set of school-related variables is examined, using Costner's multiple indicator procedure. (Author)

Describes a study of level of intellectual development displayed by a population of Australian primary school education students at the time of entry to college. Results agree with United States research which indicate that a significant proportion of high school and college students is not at the level of formal operations, an idea contrary to…

The author examines the evolutionary and neural roots of a triune intelligence comprised of a primal mind, an emotional mind, and a rational mind. A simple brain model and some definitions of unfamiliar behavioral terms are included. (Author/MA)
