“…For example, when subjects were given 5 s to try to retrieve the English equivalent of an Eskimo word, and then saw both words for 5 more seconds, later memory performance was better than when the English and Eskimo words were both available for 10 s (Carrier & Pashler, 1992). This benefit of testing over restudying-henceforth, the testing effect, also sometimes referred to as retrieval practice-has been found with learning of facts (McDaniel & Fisher, 1991), of face-name pairs (Carpenter & DeLosh, 2005), and even of visuospatial information (Carpenter & Pashler, 2007;Kang, 2010; see Roediger & Karpicke, 2006, for a review). The present article asks whether the benefits of testing are confined to tasks requiring literal reproduction or, rather, generalize to more complex forms of learning, such as function learning.…”
