On interpreting the effects of repetition: Solving a problem versus remembering a solution

https://doi.org/10.1016/S0022-5371(78)90393-6Get rights and content

When a problem is repeated, the later presentation of the problem sometimes results in the subject responding by remembering the solution rather than by going through the operations that would otherwise be necessary to solve the problem. The means of obtaining the solution is shown to influence subsequent retention performance; retention of the solution suffers if it has been obtained by remembering rather than by solving the problem. The distinction between solving a problem and remembering a solution is used in an account of the effect of spacing repetitions and other standard memory phenomena. The relevance of the distinction to tasks such as word perception is also discussed.

      These include: desirable difficulty, elaborative retrieval, and skills learning. Research has noted that retrieval becomes more effective as the effort of retrieval increases, for example through increasing difficulty of the task to complete.22-24 This can be partially attributed to increased cerebral processes involved during the act of recall.

      In contradistinction, increased rest intervals within training may generate more opportunity for variability and allow the capture and incorporation of pre- and post-session experiences, which would produce a wider view of the task and its neural representation, as proposed by the encoding variability hypothesis (see also Kovacs, Han, & Shea, 2009). Deficient processing theories suggest that massed presentations are encoded to a lesser degree than spaced presentations (Cuddy & Jacoby, 1982; Jacoby, 1978). Thus, the parsing of practice over multiple sessions has been suggested to promote superior performance due to encoding variability (Dempster, 1996).
