The cerebral laterality of children with various configurations of verbal-performance discrepancies was inferred with an objective measure of lateral preference using Verbal and Performance IQ scores of the WISC-R. Results were interpreted as lending support to the notion of competition antagonism between cortical hemispheres and a possible…

Offers case studies of "problem" students who have been motivated to learn through their interest in and talent for artistic expression. Suggests ways teachers can channel students' interests in productive ways; e.g., Individual Idea Logs (to record fantasies, doodles, inventions) and five-minute drawing breaks. (DMM)

Examines the role of the brain in conceptualizing and understanding intrapersonal communication. Drawing on research and theory from several disciplines, develops a communicative perspective on intrapersonal communication, focusing on specific interhemispheric and intermodular processes inherent in intrapersonal communication. Discusses…

A study provided hemisphere specific simulation and hemispheric alluding stimuli to 15 middle school students with L-type dyslexia and 15 with P-type dyslexia. Traditional decoding and comprehension exercises were provided to 15 students with M-type dyslexia. Readers with all types of dyslexia exhibited significant improvement in reading accuracy…

Large and reliable laterality effects have been found using a dichotic target detection task in a recent experiment using word stimuli pronounced with an emotional component. The present study tested the hypothesis that the magnitude and reliability of the laterality effects would increase with the removal of the emotional component and variations…

A study investigated whether a correlation exists between the degree and nature of left-brain laterality and specific reading and spelling difficulties. Subjects, 50 normal readers and 50 reading disabled persons native to the island of Bornholm, had their auditory laterality screened using pure-tone audiometry and dichotic listening. Results…

RESEARCH HAS SHOWN THE RELATIONSHIP OF VISUAL-MOTOR DYSFUNCTIONS TO READING DIFFICULTIES AND SCHOOL FAILURE. THIS STUDY WAS DESIGNED TO IDENTIFY THE EXTENT OF SUCH DYSFUNCTIONS IN SEVERAL GROUPS OF FULL-TIME DAY STUDENTS AND TO ASSESS THE FEASIBILITY OF VISUAL TRAINING AND POSTURE REMEDIATION METHODS FOR STUDENTS ON ACADEMIC PROBATION. WHILE THE…

It was reasoned that if the right ear/left brain hemisphere is more efficient than the left ear/right hemisphere at extracting the meaning of a sentence, then verbatim information presented to the right ear may be more difficult to retrieve than verbatim information presented to the left ear immediately after the sentence is heard. This idea was…

The purpose of this study was to determine how retarded readers differed from normal readers in the various ways laterality is manifested. An additional purpose was to investigate the development of laterality as seen across several age levels. Subjects were 80 white male 9-, 10-, 11-, and 12-year-olds from regular classrooms in suburban…

Sperry (1961) and others working on split brain learning reported that the two halves function in a nearly identical manner, giving excellent controlled replication of a learning problem. The present experiments were carried out with cats trained in a tactile discrimination apparatus, sometimes being forced to use the left paw, and sometimes being…

Reviewed is research on laterality and its relationship with reading in normal and learning disabled children. (CL)

The Scholastic Aptitude Test scores of 86 left-handed undergraduates were examined as a function of familial sinistrality, strength of left-handedness, and sex. An interaction was found between familial sinistrality and strength of handedness in terms of aptitude. (Author/BS)

Sex differences in cognitive skills, grouped into motor, spatial and linguistic areas, are assessed in relation to current theories of cerebral lateralization. Few convincing sex differences exist, either overall, or in interactions with functional localization. Qualifying criteria include age, birth order, culture, sex of experimenter and sex…

Findings support the hypothesis that lateral preference, per se, has little effect on information-processing behaviors. (Authors)
