(A) Explicit knowledge for the No-El groups which was tested following the retention test on day 4. (B) Explicit knowledge for the El groups on day 1. (C) El group explicit testing was performed at the end of the second day of practice.

A pretest of explicit knowledge was administered at the beginning of day three and repeated at the conclusion of practice for the El groups. All participants in the El groups were at least explicitly aware of the existence of a repeating sequence; recognition memory varied. Mean (standard error of the mean).

^**Below 50% represents performance worse than change on recognition tests.
