The Ontogeny of Cerebral Dominance

Abstract: It has long been known that in most people the language function depends on the activity of the left cerebral hemisphere. It is clear that language develops from a base state of no language. But does language lateralization analogously develop from a base state of no lateralization? It has been generally assumed that this is so. The child at the very beginning of language development is regarded as using both cerebral hemispheres for this purpose. Differences of opinion have related more to the time frame within which lateralization occurs (Lenneberg, 1967; Krashen, 1972) than to the question of whether lateralization develops at all.

Interactions of mothers and nurses with premature infants

Abstract: The initial attachment of three mothers to three premature infants weighing less than 1500 g was assessed by observation of the mother9s behaviour during visits to her child in the hospital nursery. Interactions of mothers and infants were compared with those of nurses and infants. Premature infants, during a stay in hospital of approximately 7 weeks, have to adapt to up to 70 different nurses and receive generally little contact stimulation from them. Mothers change in their interactional behaviour over time but show persistent individual differences in amount of touching, smiling and talking to their infants. Follow-up investigation will determine if the maternal behaviour as demonstrated in the nursery is predictive of later parenting disorders.
