Modality-specificity effects in priming of visual and auditory word-fragment completion.

In this study, the researchers examined modality-specificity effects in priming of visual and auditory word-fragment completion by the presentation of visual or auditory primes. In 2 experiments, within-modality priming and cross-modality priming were observed, with greater priming observed in the within-modality conditions. The prime was presented in a word list in Experiment 1 and either presented or inferred in priming sentences in Experiment 2. Inferring a target that was not actually presented in the sentences resulted in priming of fragment completion but not in modality specificity. These results, coupled with comparisons to explicit cued fragment completion, support the interpretation that priming of word-fragment completion is owing to both a perceptual and a nonperceptual component. This latter component may be different than the conceptual processes used for explicit memory, which did show modality specificity for inferred targets.

Priming problem solving with conceptual processing of relevant objects.

In the present study, the author explored the effect of processing relevant information on producing solutions to brief insight problems. She hypothesized that the conceptual processing of objects relevant to the target solution would facilitate that solution relative to unrelated objects or the shallow processing of words. The author also explored the effect of knowledge of the relationship between the initial object-processing task and the problem-solving task. The results showed that participants who conceptually processed objects related to the target solution (Experiment 1), but not those who shallowly processed words related to the target solution (Experiment 2), were more likely to produce the solution relative to the control; and knowledge of the relationship between objects and solutions made no difference in the frequency of target solutions produced. The results of Experiment 3 showed that conceptual processing of an object could prime a nondominant solution for an ambiguously worded problem. Taken together, the results of the studies supported the effect of conceptual processing on facilitating insight in problem solving.

Priming guesses on a forced-recall test.

The forced-recall paradigm requires participants to fill all spaces on the memory test even if they cannot remember all the list words. In the present study, the authors used that paradigm to examine the influence of implicit memory on guessing--when participants fill remaining spaces after they cannot remember list items. They measured explicit memory as the percentage of targets that participants designated as remembered from the list and implicit memory as the percentage of targets they wrote but did not designate as remembered (beyond chance level). The authors examined implicit memory on guessing with forced recall (Experiment 1), forced cued recall with younger and older adults (Experiment 2), and forced free and cued recall under a depth-of-processing manipulation (Experiment 3). They conclude that implicit memory influences guesses of targets in the forced-recall paradigm.
