Mother-infant engagements in dyads with handicapped and nonhandicapped infants: a pilot study

The purpose of this study was to investigate the effect of a handicapping condition on mother-infant interactions and, to investigate the conditions under which coordinated attention to an object and a person is demonstrated. This study provides a unique opportunity to make across-mother and within-mother comparisons of mother-infant interactions in two sets of fraternal twins. In each set, one infant was handicapped whereas the other was nonhandicapped. Microanalyses of several aspects of mother-infant free-play sessions showed that handicapped infants emitted fewer object-directed behaviors, had fewer instances in which their leads were followed, and spent relatively little time in joint attention with mother. The data also suggest that repetitive sequences with an object may be an important context in which coordinated attention is demonstrated.
