Similarity mapping in spoken word recognition

Five phoneme monitoring experiments are reported that investigate the relationship between the degree of lexical activation (based on similarity of the input to a real word) and phoneme perception. Experiment 1 showed that phoneme monitoring detection times increased as similarity of the carrier to a real word decreased. Experiment 2 replicated these results with a set of two syllable stimuli. Experiment 4 extended the results of Experiments 1 :Ind 2 to a new phoneme. Two additional control experiments (Experiments 3 and 5) were conducted with truncated stimuli where lexical contributions were removed. The results are discussed in terms of the architectural relationship between the acoustic-phonetic input, form-based lexical levels, and semantic levels Of representation. (C) 1997 Academic Press.
