Infants' motor skill development triggers changes in parent-infant interactions, exploration, and play behaviors, particularly during periods of locomotor transitions. We investigated how these transitions reorganized infants' and mothers' explorations of spatial layouts. Thirteen infants and their mothers were followed biweekly from the age of 6…

This research examined the child, parent, and family conditions under which attachment disorganization was related to both level and change in externalizing behavior during preschool among a community sample.

However, no study based on long-term observation is presently available that deals with the appearance and development of pointing as an interaction between mothers and their children. Therefore, this…

The histories and behaviors of 5 infants with deafness or hearing deficits and other disabilities were compared with 10 at-risk infants with hearing deficits, 8 infants with hearing deficits not at risk for other disabilities, and 20 normal infants. Mothers' stress levels and infants' behaviors were assessed for the three groups. (SW)

This study used the Nursing Child Assessment Feeding Scale (NCAFS) and the Nursing Child Assessment Teaching Scale (NCATS) to examine mother-infant interaction in Japanese dyads. Subjects were residing in Hikkaido, Japan, and assessments were…
