| Abstract: | Recent progress in primatology, neurology and psychology has made it possible to begin to synthesize and combine the data and concepts from these fields into the physical anthropological approach to child growth and development. This paper attempts to conceptualize this new biobehavioral approach, reviewing two studies which exemplify it, already under research at the Krogman Growth Center. The first, which deals with mother-newborn social interaction, explores neonate attachment behaviors and predictable maternal response. The methodology of this study relies heavily on ethological techniques. The second study, involving pre-pubescent and post-pubescent same sex twins, aims to delineate the genetic and environmental components of certain human behavioral qualities, such as intelligence, using the genetic approach to human variation. The problem of how this possibly interacts with the secular trend is also discussed. |
