Word-type effects in word-stem priming: evidence for semantic processing in the perceptual representation system?
While a presemantic Perceptual Representation System is believed to mediate implicit memory tasks such as word-stem priming, clinical studies suggest semantic information can be processed during priming. To clarify the nature of this system, we investigated word-type effects in word-stem priming in a nonclinical sample of 41 undergraduates who rated the pleasantness of threatening and nonthreatening words, performed implicit and explicit memory tasks, and completed measures of mood state. More nonthreatening words were primed and scores on the Beck Depression Inventory were negatively correlated with production of nonthreatening words. During cued recall, more threatening than nonthreatening words were remembered and ratings of state anxiety were negatively correlated with recall of nonthreatening words. Our findings support the contention that semantic information is processed during priming and that mood congruent biases also operate. These results may call for a reconceptualization of the Perceptual Representation System.
