Abstract
-
The primary purpose of this investigation was to test the hypothesis that implicit memory for spoken words results from the operations of a memory system devoted to pattern recognition. Pattern recognition entails pre-lexical processes, which produce a detailed record of the acoustic characteristics of a speaker's voice along with subword information. To test this hypothesis, the relation between speech perception and implicit memory was examined. Auditory repetition priming was employed as the behavioral expression of implicit memory. Phoneme monitoring latencies were used to measure speech perception and memory processes. In addition to testing the main hypothesis, Experiment 1 investigated the detrimental effect of speaker variability on memory; Experiment 2 examined whether expectations can modulate this effect; and Experiment 3 assessed the effect of voice familiarity. The results showed that although speech perception operations entailed the use of word information, implicit memory relied on pre-lexical operations. Consistent with this finding, the number of speakers comprising the acoustic environment was found to produce a linear decrement in auditory priming. Stable acoustic changes in a multiple-speaker environment during the encoding of a set of spoken words rather than expectations regarding these changes were found to modulate the detrimental effect of speaker variability on memory. Voice familiarity, however, did not improve memory. Taken together, the present findings indicate that implicit memory of spoken words entails the encoding, storage and retrieval of speaker-specific episodic representations, which are pre-lexical in nature.
