Seventeen visually impaired children, aged 7-11 years, were compared with sighted children on a test of facial recognition and a test of expression identification. The visually impaired children were less able to recognize faces successfully but showed no disadvantage in discerning facial expressions such as happiness, anger, surprise, or fear.…

THE BASIC INTENTION OF THE STUDY WAS TO INVESTIGATE MENTAL RETARDATION IN TERMS OF PERCEPTUAL AND RESPONSE ABILITY DEFINITIONS, TO TEST THESE ABILITY DEFINITIONS OBJECTIVELY, AND TO EVALUATE THEM AS THEY RELATE TO THE INTELLIGENCE FACTOR. BOTH PERCEPTUAL AND RESPONSE FACTORS WERE EXAMINED FROM THE STANDPOINT OF MENTAL DISTURBANCES WITH REFERENCE…

Practice in interpreting the critical features of incomplete line drawings and integrating fragmentary visual information was shown to enhance the visual efficiency of partially sighted children, aged 5 to 8. (BW)

A comparison of test results on the Visual Discrimination Test was made between a group of 22 reading disabled children and 22 children who were reading on or above grade level. Both groups were of average or above-average intelligence and the two groups were matched for age and sex. The mean age was 10 years and 3 months and all the reading…

Maintains that having students estimate the size and width of a class waste paper can (placed on a desk) is a simple and effective way of illustrating perceptual distortion. Tests show that people will consistently overestimate the height of the can, allowing for a useful discussion on sensory distortion. (MJP)
