The past 15-20 years have witnessed a particularly strong interest in our ability to rapidly extract structured information from the environment. This fundamental process of human cognition is widely believed to underpin many complex behaviors – from language development and social interaction to intuitive decision making and music cognition – so this interest spans practically all branches of cognitive science. Research on this topic can be found in two related, yet traditionally distinct research strands, namely "implicit learning" (Reber, 1967) and "statistical learning" (Saffran, Aslin, & Newport, 1996).
