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)

The present experiment was an attempt to determine whether, under different testing procedures and with different stimulus materials, an effect of poststimulus study time on picture recognition could be demonstrated. (Author)

It has been proposed that the ability of a visual noise mask to stop processing of a target stimulus under backward-masking conditions be gauged by its ability to obscure the target when both stimuli are viewed simultaneously. Authors assessed the usefulness of this proposal. (Editor/RK)

Differential fixation to novel stimuli was obtained from 4-month-old infants to test the discrepancy hypothesis, which predicts a curvilinear relationship between degree of discrepancy and attention. (ST)

Young children usually prefer to classify objects on the basis of shape rather than color. The present study explored this phenomenon with a stimulus matching test and a component selection test. (ST)

In a study of spatial perspectives, third- and fifth-grade students were asked to coordinate perspectives on single-object and multiple-object arrays. (ST)

The present study was designed to identify sources of information in the human face and to determine how this information is processed by young children in solving problems. (ST)

The development of the ability to associate numerals with sets of appropriate size was studied in children, ages 4 to 5-1/2. (ST)

A historical sketch of the development of Otto Neurath's visual science method called International System of Typographic Picture Education (ISOTYPE). (HB)

The present experiment was designed to investigate the influence of label training on the reporduction-recall of visual stimuli and follows in the tradition of the Gestalt memory-for-form literature. (Author)

Presents an investigation of the hypothesis that specific reading disability is attributable to inadequate visual memory. A total of 126 subjects, ages 7-14, who were asked to demonstrate retention of randomly arranged Hebrew letters on three separate occasions, provided no evidence that deficient visual memory is a likely source of reading…

Ambiguous pictures that could be seen as faces or as meaningless patterns were the stimuli in two recognition-memory experiments. Recognition was far more accurate when the stimuli were seen as faces. (Editor)
