The relationship of visual field to brain function is examined in research, and the correlation of gifted students' use of visual field of Piagetian theories of formal logical thought is analyzed. (C L)

To test the suggestion that a deficit in selective attention is characteristic of learning disabled (LD) but not hyperactive (H) children, 72 students (12 LDH, 12 H, and 36 normal Ss) were timed on visual search tasks. (Author)

When stimuli differed on two dimensions (size and shape), either of which furnished enough information for a correct response, eight educable retarded adults were faster to discriminate than when stimuli differed only on dimension. (Author)

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)

In an examination of the validity of the Visual Closure subtest of the Illinois Test of Psycholinguistic Abilities, 94 learning disabled students (mean age 9 years) were administered three visual measures. (CL)

To determine the intertest reliability of the Beery Developmental Test of Visual Motor Integration (VMI) and the Bender Visual Motor Gestalt Test (BGT), 64 six to nine year olds were administered both tests.

In studies with 22 normal hearing adults and two hearing impaired children (12-13 years old), speech was presented under different degrees of optical distortion. (CL)

Cited is research which indicates that ocular motor abnormalities in children with reading difficulties are factors in the processing of visual information. (CL)

Twenty-two third-grade good and poor readers were tested for their ability to name pictures while trying to ignore words or nonword strings of letters printed inside the pictures. Both groups experienced more interference from intracategory than extracategory words, indicating that they processed the words automatically. Only the good readers…

Thirty-nine fourth grade children exposed to a haptic (active touch) match-to-sample task made significantly fewer post-test errors, relative to control subjects, on a visual problem-soving task. (Author/PHR)
