We report the first major genetic study of mild mental impairment. From a representative sample of 3,886 twins (1,314 monozygotic, 1,296 dizygotic same-sex, and 1,276 dizygotic opposite-sex), the lowest 5% were selected on a composite measure of verbal and nonverbal abilities assessed by parents when the twins were 2, 3, and 4 years of age. Twin…

This book describes a neuro-developmental approach to learning difficulty assessment and remediation through assessment of a student's reception of information through the sensory channels, processing of sensory information in the brain, and repertoire of responses for expression. Chapter 1, "Reflexes: Their Impact on Success or Failure in…

The unit provides information on the study of the human brain for students in grades 5-9 with suggestions for extending the lessons for gifted and talented students. Learning activities are offered for ten lessons (sample subtopics in parentheses); introduction to the unit (student pretest and posttest); brain growth; medulla-oblongata-reptilian…

Research findings in the area of brain growth periodization establish that the human brain does not grow on a constant continuum. Eighty-five to ninety percent of youngsters of average and above ability experience periods of great brain growth between ages 3-10 months, 2-4 years, 6-8 years, 10-12 years, and 14-16+ years. Mental growth data have…

Reported is a research program to observe children at high risk for schizophrenia and explore possibilities of prevention. Characteristics of the high risk group (n=207) observed during 1962 are discussed, and a theory which suggests that schizophrenia is an evasion of life is explained. Among results of a diagnostic assessment conducted 10 years…

Some of the major lines of investigation that point to neurophysiological factors in spatial skill are presented. These lines include: the two hemispheres of the brain, recent studies, tachistoscopic studies, morphological differences between the cerebral hemispheres, Geschwind and Levitsky's discovery, cerebral dominance re-examined, sex…
