Early mother-infant interaction and 24-hour patterns of activity and sleep.

Studies of mother-infant interaction carried out at Boston University Medical Center over the past decade have been directed at the task of documenting earliest interactional behavior in greater detail as well as searching for a logic which might bring greater coherence to the diversity of that detail. The research approach has reflected the viewpoint that at the outset of life such a logic can be sought in the constraints to interaction imposed by vital biological determinants concerned with regulation, adaptation, and, in the large view, organization. Once one begins to examine the problem of adaptation and to design research revelant to it, the scope of the issues involved becomes apparent, as does the extent of ignorance regarding the mechanisms responsible for the adaptive process.
