This quantitative study of imagery in 96 undergraduates addresses the problem of individual differences in the characteristics of mental imagery workspaces. A 20-item questionnaire embodying nine characteristics of mental imagery workspaces was administered to 78 females and 18 males. Analysis of variance by gender disclosed significant higher…

The effect of a relevant analogy and of subject visualization on the amount of cognitive capacity needed to process unfamiliar information about science was investigated. The dependent measure was reaction time on a secondary task while listening to six tape recorded passages about chemistry and physics in a 2 x 2 x 6 mixed design. The analogy…

A graphical method is proposed which allows one to visualize a real matrix and its inverse. In this scheme, various special properties of the matrix are easily recognized. Up to 5x5 matrices can be graphed on an average page if the range of values does not exceed two orders of magnitude. (Author/LS)

Six studies were performed investigating the relationship between digit span (DS) capacity and other memory and problem solving tasks: (1) Ss were administered a DS test, an aurally presented mental addition test, a similar multiplication task, and a written timed division test. DS correlated only with the second; (2) Ss were required to…

A 90-minute computer-assisted instruction (CAI) unit course supplemented by a 1-hour lecture on the dynamic nature of three-dimensional rotations and Euler angles was given to 29 undergraduate engineering students. The area of Euler angles was selected because it is essential to problem-working in three-dimensional rotations of a rigid body, yet…

Sixty of the possible beginning phonemes of English monosyllables were paired with the vowel /a/ in nonsense syllables, and used in illustrative one-syllable words. The sixty manners of commencing words had been scaled in terms of their relative perceptual similarity-dissimilarity in sounds. Both syllables and words were divided into three levels…

The findings of this study indicated that induced imagery facilitated correct shape reproduction in 8-year-olds better than induced verbalization. (JMB)

Suggests lessons based on categorizing and several learning modalities to expand students' vocabulary. (MKM)

Relation of male adult age and performance on memory for designs was determined by analyzing three cross-sectional samples, two longitudinal samples, and within-cohort comparisons of men born in same period, tested at different times. Results indicate age declines in memory-for-designs performance but only small vocabulary change. (Author)

The factor differentiation hypothesis suggests that the factor structure of a set of tests tends to differentiate over time, becoming more complex and articulated. This experimental study provides evidence confirming that hypothesis. (Author/JKS)

The predictability of individual differences in the ability to reason about dynamic displays from tests using static displays was studied in 170 adults given paper-and-pencil and computer controlled tests. Several multivariate analyses indicated that the ability to reason about dynamic motion was distinct from the ability to reason about static…

Provides tentative evidence to suggest the presence encountered in a dark tunnel as reported by near-death experiencers may not always be the higher self, especially for victims of child and sexual abuse. Presents three case histories which suggest that in some cases presence may be a female who provides comfort to suffering children. (Author/NB)

Spelling tricks for 35 sight words that can be used by learning disabled or regular classroom students are given. They include replacing silent or confusing letters with pictures to aid visual recall; locating a smaller, more familiar word in the longer word; and rhyming certain letter groups to related words.
