Compares estimates of monocular visual resolution of children 6- to 36-months of age with three psychophysical procedures: the Probabilistic Estimation by Sequential Testing (PEST), a modification of the PEST procedure, and the method-of-constant stimuli. (HOD)

Two experiments examined the effect of concurrently holding 0, 2, 4, or 6 nouns in memory on the recognition of visual stimuli briefly presented to the left or right visual fields. (Editor)

It is proposed that in the process of letter perception a preliminary nonverbal code is available in the right hemisphere until superceded by a verbal code in the left hemisphere. (Editor)

The data indicate a negative relationship between illusion susceptibility and education. This supports the sophistication hypothesis suggested by Segall, Campbell, and Herskovits. (DB)

An Ames static trapezoidal window was used to test infants' responsiveness to pictorial depth. Sensitivity to the pictorial information for depth that is present in the trapezoidal window appears to develop after the age of 22 weeks. (Author/DB)

Reports effects of context that are entirely perceptual. Visual discrimination was enhanced when line segments were flashed in a region that was perceived as a figure. Discrimination was substantially degraded when the same region was seen as ground although the physical stimulus remained identical throughout figure-ground reversals. (Author/JN)

Studies demonstrate increasing glucose metabolic rates in human primary (PVC) and association (AVC) visual cortex as complexity of visual scenes increase. AVC increased more rapidly with scene complexity than PVC and increased local metabolic activities above control subject with eyes closed; indicates wide range and metabolic reserve of visual…

Preferential looking at stimuli varying in temporal frequency was examined in 11 prematurely born infants. The relationship between amount of looking and stimulus frequency yielded a significant linear trend with the fastest frequency used (4 hertz) being most preferred. (Author/DB)

The time course of kindergarten children's memory for left-right orientation during the first 2 l/2 seconds after receptor stimulation was investigated by means of a successive matching-to-sample task with tachistoscopically presented abstract figures. (Author/DB)

This study found that color in a film helped fourth- and fifth-grade students of all ability levels learn incidental information, but affected learning of task-relevant information differently depending on ability level. (Author/JEG)

Performance by 77 hearing-impaired elementary students on test of visual processing was compared with scores on a test of reading comprehension. Performance intelligence quotient correlated with both visual processing and reading scores. Some variance in reading scores was explained by intelligence quotient and performance on memory tests for…

Event-related potentials (ERPs) of children and adults were measured while subjects observed pictures of facial expressions. Adults had greater ERP responses to happy than to angry faces, whereas children had greater ERP responses to angry than to happy faces. (BC)
