This annotated bibliography on visual perception and its relation to reading is composed of 55 citations ranging in date from 1952 to 1965. Its divisions include Perception of Shape by Young Children, Perception of Words by Children, Perception in Backward Readers, and Perception of Shapes, Letters, and Words by Adults. Listings which include…

The purpose of the two experiments was to assess the effects of two levels of stimulus redundancy and three levels of irrelevant visual stimulation on performance in a successive discrimination task and a reproduction task. The results indicate that increases in redundancy facilitated performance in the reproduction task but had no appreciable…

This study investigates the hypotheses set forth by Russian researchers that there may be identified a pervasive characteristic of the central nervous system labeled as "strength". Ten of the 12 measures used were direct replications of representative strength measures derived from the Russian work. Two additional measures were included to test…

Human recognition behavior is influenced by the phenomenon of shape constancy, which occurs when the shape of an object is correctly perceived regardless of the orientation of the object in space. The research reported here tests the validity of the shape-slant invariance hypothesis, a theoretical formulation of the phenomenon of shape constancy.…

A study investigated changes in recognition time for short sentences presented on television screens of varying sizes with viewers at varying distances. In a posttest only control group design, subjects in several different groups viewed a series of similar sentences under conditions where screen size and distance from the screen were varied. The…

Visual preference technique was found to be a method for exploring the genesis of normal and abnormal selective attention, pattern discrimination, and recognition memory. The study of infants with differing degrees of risk for mental subnormality produced substantial evidence for relationship between early visual selectivities and future…

Some infants, soon after birth, are capable of storing visual information as reflected in their ability to detect and respond to change in the immediate environment. (Author)

Testing Pollack's hypothesis that decreases in effective contour contrast (resulting from a decrease in receptor sensitivity with age or from a change in actual stimulus contrast) lead to decreases in illusion magnitude. Conclusions are questioned by Sjostrom and Pollack (PS 501 740). (Author/MB)

Children's abilities to judge "who is older" without using size as a cue were studied. Five-year-olds were better able to discriminate age than four-year-olds but were not equal to adults. No significant sex differences were found. (Author/RD)

Effects of target-noise similarity on the ability to discriminate between two target letters were investigated. Performance was low when the noise letter shared the same name as the target. Thus, interletter interference effects cannot be explained in terms of inhibition between visual features. A "cognitive masking" hypothesis is proposed.…

Matching-to-sample skills are involved in language acquisition and reading and counting abilities. The rapid, even errorless, induction of matching performances in young children and 28 individuals with mental retardation (ages 11-20) was demonstrated through the structuring of a visual array that promoted detection of the relevant stimulus.…

In three experiments, three normal preschoolers were presented with sorting tasks ordinarily insoluble for four-year-olds. Found that, although the subjects had difficulty correctly sorting the pictures when told what criterion to sort by, they could provide correct answers when asked what they were looking for. This self-instructional effect was…
