A study involving deaf and hearing children investigated the perceptual abilities of deaf children employing tasks with both simultaneously and sequentially presented stimulus material. A series of motion picture tests, mostly involving abstract geometric figures, suggested that deaf and hearing children are comparable on visual memory tasks and…

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…

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)

Primacy and recency aspects of short term memory (STM) were investigated with 30 learning disabled (LD) and 30 normal children, all with a mean age of 113 months. The pretest experiment compared the serial position curve performance of LD and normal children when seven-digit series were presented visually or auditorially. The second experiment…

Three short studies were conducted on long-term effects of visual perception training on perceptual memory, involving the visual illusion of apparent movement, in educable and trainable mentally retarded children (EMR and TMR) and in learning disabled children (LD). Variables were lengths of training session and retention interval. Tables…

Twenty-eight kindergarten children (5-6 years old) were tested in order to identify children with learning disabilities and to compare tests results. (Author)

Among the findings were that there was no significant difference in performance between Down's syndrome, other mentally handicapped, and normal Ss matched for mental age, when extraneous developmental factors were eliminated; and that there was no relationship between mental age and visual perception in any group.

Findings suggested that a deficit in auditory memory rather than cross-modal perception appears to be a factor in poor reading comprehension. (Author/DLS)
