Can 6-month-old infants process causality in different types of causal events?

Two experiments investigated 6-month-old infants' processing of causal and noncausal events with the habituation/dishabituation technique. Experiment 1 was carried out with the usual launching events. Results showed that 6-month-old infants can recognize the presence of causality embedded in a direct launching event. Experiment 2 was carried out with a previously univestigated type of causal event: the entraining event. Results showed that 6-month-old infants could nor process causality through a direct entraining event. Findings are discussed in terms of compatibility with a modular or an information-processing framework.
