Implicit learning of first-, second-, and third-order transition probabilities

Most sequence-learning studies have confounded different types of informati on, making it difficult to know precisely what is learned. Addressing many of the confounds, the current study shows that people can learn 1st-, 2nd, and 3rd-order transition probabilities. Measures directly assessing awarene ss of the probabilities show that the knowledge is implicit early in traini ng and becomes explicit with extended training.
