If infants attribute a special causal status to direct launching, they should dishabituate more if the test event differs from the habituation in terms of causality compared to if it does not. A key experiment by Leslie (1984) put forward the argument that infants' causal perception is much like adults, and subject to little or no developmental change. However Cohen and Amsel (1998), with support from previous research Cohen (1998) and Oakes and Cohen (1994), have argued on the basis that causal perception is the result of systematic development through the first year. The two approaches to the question of causal development in infants represent a modular, nativist framework, predicting similar results in all three groups, in this article referenced through Leslie's work (1982; 1984), and a constructivist developmental framework. This predicts recovery of attention to events differing in terms of causality only at ...
