Article reviewed some recent research on hemispheric lateralization of the human brain. (Editor/RK)

Article investigated a more precise characterization of dominance with the focus on recent research on the brain's left hemisphere. (Author/RK)

The relationship between neurological impairment or brain damage and severe reading disability is investigated. Symptoms and causes of neurological impairment are listed, and reading disability theories are discussed. Smith and Carrigan offer a neurochemical explanation of reading disability based on synaptic transmission problems. Orton,…

In an effort to explore S. Orton's "intergrading" hypothesis, six developmental dyslexics (ages 16 to 47) and four good readers were tested on measures of interhemispheric coordination. Dyslexics showed reduced laterality bias and longer response latencies to bihemifield stimuli. (Author/DB)

Middle and secondary school students who continue to display reversal problems despite intervention should be taught to compensate. Compensation can be based on the student's common error problems. (CL)

Five male learning disabled students (eight to 13 years old) learned more words using the nonpreferred hand in tactile processing to remediate reading than with the preferred hand. (CL)

Compared four-year-old left-handed children and children lacking definite hand preference with right-handers on motor skills. Found no differences between left-handers and right-handers of either sex, but the children lacking hand preference had lower scores. Possible sex differences and implications for the education of children lacking…

Reports a study of the lateral preferences and left minus right hand movement time of 129 pupils attending a dyslexia clinic for remedial teaching, and the incidences of left handedness and developmental language problems in relatives. (RH)

In an attempt to further substantiate Bender's throry of maturational lag as a factor in schizophrenia, 72 schizophrenic children, ages 7 to 15 were tested on their ability to make right-left discriminations. The results indicated that the schizophrenic children as a group performed substantially poorer than normal children. (CS)

Investigated hand preference using a questionnaire. Respondents were divided into: right-handers (N=523), left-handers (N=412), and impossible to classify (N=42). Items were subjected to a cluster analysis. Results show a clear grouping of items for left-handers and a vaguely similar grouping for right-handers, characterized by the muscle groups…

Research is reviewed concerning the current state of knowledge about normal hemispheric specialization; distinctions among such terms as dominance, laterality, and lateralization; and models of abnormal cerebral organization in dyslexic children. The question of dyslexic subtypes is undertaken along such dimensions as handedness, eyedness, and…

The behavioral manifestations of hand, eye, foot, and ear preference were studied in a sample of 384 children of 3, 4, and 5 years of age, and were compared to the preferences of a group of 171 high school students. Results indicate that some aspects of lateral preference behavior are influenced by age-related variables. (Author/RH)
