Peer reviewedMosley, James L. – American Journal of Mental Deficiency, 1978
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)

Peer reviewedWiig, Elisabeth H.; Neurman, Jane E. – American Annals of the Deaf, 1972
Response patterns of deaf and hearing children in matching visual stimuli employing the dimensions of color, size, orientation, and form were compared. (KW)

Switzky, Harvey N.; And Others – AAESPH Review, 1979
The results suggested that profoundly retarded children do show habituation and dishabituation to visual stimuli and are actively storing and processing information about their perceptual world. (Author/DLS)

Analysis of the Averaged Visually Evoked Potentials in Normal Children. (RIEEC Research Bulletin 3.)
Download full textMizutani, Tohru; And Others – 1973
Evaluated were the properties and fine structures of averaged visually evoked potentials (AVEP) in 60 normal children between the ages of 2 and 9 years. Electroencephalographic recordings were taken while white diffuse flashes were used to deliver visual stimuli to the Ss. Three types of AVEP patterns were discerned, with no relationship observed…

Visual perseveration was investigated within educable mentally retarded and second, fifth, and eighth grade normal children (N = 12 each group). (Author)

Peer reviewedHicks, Wanda M. – American Annals of the Deaf, 1979
A study involving eight youths and adults with retinitis pigmentosa (and only 20 degree visual field and hearing loss of at least 20 decibels) determined variance in the ability to perceive and comprehend visual stimuli presented by way of the manual modality when modifications were made in configuration, movement speed, movement size, and…

Peer reviewedStratford, B. – Journal of Mental Deficiency Research, 1979
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.

Peer reviewedThor, Donald H. – American Journal of Mental Deficiency, 1973
The deficit in counting ability was examined through assessment of counting and tracking task performances of 18 adolescent educable mentally retarded (EMR) boys and through comparision of performances of 20 EMR boys and 20 younger normal boys. (Author/MC)

Peer reviewedFriedlander, Bernard Z.; Knight, Marcia S. – American Journal of Mental Deficiency, 1973
Sixteen deaf-blind, retarded, preschool postrubella children (mean age 6 years) were tested in an operant procedure which allowed them to select preferred illumination feeback as reinforcement for operating a simple two-choice lever switch. (Author/MC)
