Role-differentiated bimanual manipulation (RDBM) is a complex behavior requiring the complementary movement of two hands to achieve a common goal. The current study investigated the relation of RDBM efficiency (speed to complete a successful RDBM) with hand preference, toy type (simple/difficult), age, and hand used to perform the RDBM. This study observed 46 infants between the ages of 9 to 14 months, each with a different hand preference category. Changes in RDBM efficiency across time were examined across different hand preference groups for RDBMs performed on simple toys using the right hand. The analysis revealed that early-right preference infants had …

Sitting is one of the first developmental milestones that an infant achieves. Thus measurements of sitting posture present an opportunity to assess sensorimotor development at a young age, in order to identify infants who might benefit from therapeutic intervention, and to monitor the efficacy of the intervention. Sitting postural sway data was collected using a force plate from infants with typical development, and from infants with delayed development, where the delay in development was due to cerebral palsy in most of the infants in the study. The center of pressure time series from the infant sitting was subjected to a …
