Participants are given tasks designed to elicit knowledge that was acquired incidentally or unconsciously and is evident when performance shows greater inclination towards items initially presented than new items. Performance on indirect tests may reflect contributions of implicit memory, the effects of priming, a preference to respond to previously experienced stimuli over novel stimuli. Types of indirect memory tests include The Implicit Association Test, The Lexical Decision Task, The Word Stem Completion task, Artificial Grammar Learning, and Word Fragment Completion.
