The first aim of this study was to assess the proportion of students at different levels in a Nigerian secondary school who interpret selected diagrams in 3 or 2 dimensional terms and to see if there are differences between these interpretations and those of English students. (Author/AM)

Fifth grade students completed ten trials of recalling familiar nouns plus two summary trials. Alpha factor analysis indicated that the measurement procedures may be conceived of as derived from a single domain and the use of a summary trial was a simple way to increase the generalizability of a particular measurement procedure.

A program designed to test the visual literacy of fourth grade students was described. Its basic purpose was to provide many experiences in which children must arrive at evaluative decisions, make comparisons, and use their imaginations. (Author/RK)

The instigative aggression paradigm, in which male and female subjects instructed a female confederate which shock to set for an opponent in a competitive reaction time task, was employed. Results were discussed in terms of violation of task role and sex role expectations. (Editor/RL)

Seven children aged 7 to 9 years were auditorily presented five-digit numbers for retention intervals of 0 to 10 seconds. Pupil size was recorded during stimulus presentation, retention interval, and recall of items. (Author/SB)

Two-letter stimulus displays, differing in the magnitude of the horizontal spatial separation between the letters, were presented tachistoscopically to 10 retarded and 1 nonretarded adults. (Author/CL)

This study is a detailed analysis of the course of habituation of preschool children to visual stimuli using behavioral measures as data. (Author/SB)

Two experiments examined preschoolers' visual and verbal coding processes in a pictorial short-term memory task. Results of both experiments indicated that high visual similarity had a deleterious effect on recall accuracy regardless of the verbal codability of the stimuli. (Author/JMB)

An experiment is reported in which 25 listeners were presented with pairs of stimuli of equal duration, but differing in fundamental frequency, and were asked to decide which of the two stimuli was longer. (Author/RM)

Groups of 7 1/2-month-old infants heard 1 of 8 episodes consisting of no, slight, moderate, or large discrepancy between a habituated standard and a transformed auditory stimulus. Patterns of cardiac deceleration supported the hypothesis that attentiveness is an inverted-U function of the degree of discrepancy between stimulus event and schema.…

Marks (1973) and Gur & Hilgard (1975) have reported success in predicting performance in visual-memory tasks from scores in a questionnare of self-rated vividness of imagery, i.e. the Vividness of Visual Imagery Questionnaire (VVIQ; Marks, 1973). These findings were disconfirmed in two experiments in which the VVIQ was used and vivid pictures…

Described is a prosthesis that connects a television camera and associated circuitry to the visual centers of the brain to restore a limited amount of visual sensation to totally blind persons. (Author/MH)

Two studies examined recognition memory for pictures in elementary school children and adults. Photographs were used which showed either single objects or multi-object scenes and distractors which differed from targets in that an element had been added, an original element moved, or the vantage point changed. (Author/JMB)

The influence of stimulus number and familiarity on judged duration were investigated. Results showed that the number of stimulus elements presented within a given interval affected its perceived duration, although the familiarity of those elements (as defined herein) did not. (Editor/RK)
