Visual constraints in the development of action

The chapter's aim is to understand the role of visual information in the control of avoidance and interception behaviors in infancy from the ecological psychology approach to perception and action. We show that during infancy developmental change in action is associated with the use of different information sources and that this process of attunement promotes the perceived action possibilities (affordances). In the final section, we position these findings within Milner and Goodale's two-visual system model, which holds that perception and action are mediated by two functionally and neuron-anatomically separate visual (sub-)systems. © 2007 Elsevier B.V.
