The author considers cerebral dominance and brain asymmetry, the development of the cerebral cortex and examples of aberrancy, and diseases of the immune system, all of which relate to recent anatomical and epidemiological findings in developmental dyslexia. These discoveries have led to testable hypotheses which may enhance current understandings…

Children (N=434) with nonsyndromic mental retardation were analysed for frequency of prenatal, perinatal and infantile biological disturbances.

Literature is reviewed on biobehavioral state and orienting (the reflex alerting to a novel stimuli and resulting in physiological arousal) in an attempt to identify conditions that are prerequisite to or facilitate learning in the profoundly retarded. Several areas are identified where further research is needed. (Author)
