Research on the role of visual memory and serial recall in dyslexia is reviewed. Findings touch on feature theory, which proposes that information is held in the form of "features," and that students for example learn to discriminate letters by marking certain identifiable aspects. Other studies are described which focus on speed of processing…

A study tested the theory that an item that stands out from its background is better remembered than one that is similar to the background (the isolation effect). Specifically, the study examined whether the isolation effect would be greater when there was a larger and more confusing mass of background items, whether position of the isolated item…

One theoretical model for understanding the visual event suggests that a visual event has both a surface (descriptive) and a deeper (experience) level of understanding. Both levels are needed to comprehend and appreciate images, with each level affecting the other. A person's perspective is an important part of the visual event, which depends upon…

The effect of labels influences nursery school children to process or store information about associated pictures more effectively than they would have done in the absence of labels. (Author/DEP)

Compared was the visual memory of 18 deaf and 18 normal hearing children (7- to 12-years-old). Ss' visual discrimination and visual memory were tested with filmstrip materials from Project LIFE (Language Improvement to Facilitate Education). Time scores and error scores were used to measure the performances of both groups. Results showing that…

The purpose of this study was to determine whether there were any differences between the responses made by selected college students to information presented in a visual context and to the same basic information presented in a verbal context. Selected college students were asked to respond to pictorial information and to the same basic…

The analysis of previously obtained data concerning short-term visual memory and cognition by a method suggested by Tucker is proposed. Although interesting individual differences undoubtedly exist in people's ability and capacity to process short-term visual information, studies have not generally examined these differences. In fact, conventional…

In a series of six experiments, undergraduate college students visually imagined letters or words and then classified as rapidly as possible the imagined letters for some physical property such as vertical height. This procedure allowed for a preliminary assessment of the temporal parameters of visual imagination. The results delineate a number of…

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)

The four BASIC programs described can be used to control experiments and facilitate classroom demonstrations and laboratory exercises in human memory, operant behavior, and visual discrimination. (RM)

The article summarizes findings of research on individual differences in reading ability, noting the primary effects of lack of phonological awareness on the ability to phonologically segment, analyze, and synthesize the speech stream. Other sources of individual differences are also addressed: early visual processes, naming processes, context,…

Four experiments investigated the nature of spatial representations used in locomotion. Participants learned the layout of several objects and then pointed to the objects while blindfolded in 3 conditions: before turning (baseline), after turning to a new heading (updating), and after disorientation (disorientation). The internal consistency of…

Textons are elongated blobs of specific color, angular orientation, ends of lines, and crossings of line segments that are proposed to be the perceptual building blocks of the visual system. A study was conducted to explore the relative memorability of different types and arrangements of textons, exploring the time course for the discrimination…

The relationship between visual recognition memory and performance on a paired-associate task for good and poor readers was investigated. Subjects were three groups of 21, 21, and 22 children each, with mean IQ's of 98.2, 108.1, and 118.0, respectively. Three experimental tasks, individually administered to each subject, measured visual…

A comparison was made of short- and long-term visual and auditory memory in relation to visual and auditory interference. The questions investigated were: (1) will interference be greater when it occurs in the same modality (auditory or visual) in which it was learned (i.e., similarity hypothesis), or (2) will interference be greater when it…
