“…In addition to issues of attentional deficits, any neuropsychological theory of attention that utilizes concepts of cerebral specialization and hemispheric lateralization must also address the controversy of whether lateralization is present at birth (Kinsbourne & Hiscock, 1977), develops over time from bilateral to increasing unilaterality as the brain matures (Lennenberg, 1967), or there is a bilateral but unequal hemispheric representation of language which, over development, changes in the degree of lateralization (Satz, Bakker, Teunissen, Goebel, & Van der Vlugt, 1975). Attentional theories based on right hemisphere dominance, hemispheric specific priming, or lateralized neurotransmitter systems would be difficult to support in a young nonlateralized child.…”
