Abstract	It is suggested that in human adults the use of visual information for action mode selection and movement control is dissociated (Milner & Goodale, 1995, 2008). More specifically, action mode selection primarily relies upon allocentric information, whereas movement control mainly exploits egocentric information. In the present study it is investigated whether this dissociation is already present in 6to 10-monthold infants; that is, whether usage of allocentric information is limited to action mode selection (i.e., reaching with one or the other hand) or is also exploited for movement control (i.e., reaching kinematics). Infants were presented with laterally approaching objects at two speeds (i.e., 20 and 40 cm/s) against a stationary or moving background. Background motion affects allocentric information about the object's velocity relative to its background. Results indicated that object speed in relation to infants' action capabilities constrained both infants' action mode selection and movement control. Background motion also affected action mode selection, albeit that the effects of object speed were more pronounced. Importantly, background motion did not affect movement control, except for movement onset. These findings indicate that information usage is not completely dissociated for action mode selection and movement control during early development, although alternative interpretations cannot be ruled out.
