(Baltimore, MD) In a new study published today in the journal Developmental Science (Epub ahead of print), researchers from the Kennedy Krieger Institute and Vanderbilt University found that early motor experiences can shape infants' preferences for objects and faces. The study findings demonstrate that providing infants with "sticky mittens" to manipulate toys increases their subsequent interest in faces, suggesting advanced social development.
This study supports a growing body of evidence that early motor development and self-produced motor experiences contribute to infants' understanding of the social world around them. Conversely, this implies that when motor skills are delayed or impaired as in autism future social interactions and development could be negatively impacted.
"Our results provide us with a new way to think about typical, and also atypical, development," said Klaus Libertus, PhD, the study's lead author and a research scientist at Kennedy Krieger Institute's Center for Autism and Related Disorders. "The mind is not independent from the body, especially during development. As motor skills advance, other domains follow suit, indicating strong connections between seemingly unrelated domains. Such connections have exciting implications, suggesting that interventions could target the motor domain to foster social development."
Previous research has found that infants diagnosed with autism spectrum disorders (ASD) show less interest in faces and social orienting. While the current study was conducted with typically developing infants, it indicates that infants who are at risk for ASD or show signs of abnormal social development may benefit from motor training as early as 3 months of age.
"For parents, this means that early motor development is very important and they should encourage motor experiences and active exploration by their child," said Dr. Libertus. "Fostering motor development doesn't h
