My specific area of research deals with how human infants learn perceptual-motor behaviors such as reaching, crawling, and walking. In more detail, my key area of interest lies in how young infants take advantage of early sensory-motor experiences in order to begin performing these adaptive behaviors. Studies are designed in such a way as to examine the processes of change as infants are provided with opportunities to gain unique sensory-motor experiences.
Another area of investigation is aimed at addressing the impact that early sensory-motor experiences have upon the development of hand preference. For instance, how do unique sensory-motor experiences modify the developmental trajectory of hand preference? How do ongoing perceptual-motor behaviors, such as crawling and walking, impact hand preference?
Finally, studies are being designed to investigate how infants utilize environmental information in order to adapt their perceptual-motor behaviors to meet specific task demands. For instance, how do infants use visual information to plan their reaching movements? How do infants modify their reaching movements when presented with an obstacle that blocks their preferred reaching hand?
