Three studies examined the development of category-based induction using an induction then recognition (ITR) procedure in which participants make category-based predictions about study items and are then given a surprise recognition test that requires discrimination between old and new category members. Exposure duration for study items was either self-paced (Experiment 1) or fixed for 5-year-olds and adults (Experiments 2a-b). Adults always showed a decrement in recognition performance following induction. Children showed the same decrement when exposure duration was equated across age groups. These results show that both young children and adults spontaneously access category-level information during induction. When study exposure time is self-paced, however, children may process additional, noncategorical aspects of study stimuli.
