Failure of further learning: activities, structure, and meaning.

Previous research has shown that little benefit is achieved through spaced study and recall of text passages after the first recall attempt, an effect that we term the failure-of-further-learning. We hypothesized that the effect occurs because a situation model of the text's gist is formed when the text is first comprehended and is consolidated when recalled; it dominates later recall after verbatim memories of more recent study episodes have been lost. Experiments 1 and 2 attempted to circumvent the effect by varying the activities of participants and requiring interactive exploration.
