Overcoming fixation with repeated memory suppression.

Fixation (blocks to memories or ideas) can be alleviated not only by encouraging productive work towards a solution, but, as the present experiments show, by reducing counterproductive work. Two experiments examined relief from fixation in a word-fragment completion task. Blockers, orthographically similar negative primes (e.

Effects of similarity on environmental context cueing.

Three experiments examined the prediction that context cues which are similar to study contexts can facilitate episodic recall, even if those cues are never seen before the recall test. Environmental context cueing effects have typically produced such small effect sizes that influences of moderating factors, such as the similarity between encoding and retrieval contexts, would be difficult to observe experimentally. Videos of environmental contexts, however, can be used to produce powerful context-dependent memory effects, particularly when only one memory target is associated with each video context, intentional item-context encoding is encouraged, and free recall tests are used.

Multiple-choice tests exonerated, at least of some charges: fostering test-induced learning and avoiding test-induced forgetting.

Among the criticisms of multiple-choice tests is that-by exposing the correct answer as one of the alternatives-such tests engage recognition processes rather than the productive retrieval processes known to enhance later recall. We tested whether multiple-choice tests could trigger productive retrieval processes-provided the alternatives were made plausible enough to enable test takers to retrieve both why the correct alternatives were correct and why the incorrect alternatives were incorrect. In two experiments, we found not only that properly constructed multiple-choice tests can indeed trigger productive retrieval processes, but also that they had one potentially important advantage over cued-recall tests.

Thinking can cause forgetting: memory dynamics in creative problem solving.

Research on retrieval-induced forgetting has shown that retrieval can cause the forgetting of related or competing items in memory (Anderson, Bjork, & Bjork, 1994). In the present research, we examined whether an analogous phenomenon occurs in the context of creative problem solving. Using the Remote Associates Test (RAT; Mednick, 1962), we found that attempting to generate a novel common associate to 3 cue words caused the forgetting of other strong associates related to those cue words.
