2006, Doctor of Philosophy, Ohio State University, Psychology.
The word recognition system is a remarkably robust system. Given this robustness, how tolerant is the system of noise within the speech signal, such as phonological mismatches? A phonological mismatch is when a phoneme is substituted in a word to create a nonsense word. For example, “bemocrat” differs from “democrat” in terms of the initial phoneme. Phonological mismatches vary along two dimensions: position (initial or medial) and distance. With regards to distance, a phoneme can be altered by either one distinctive feature (near change), or two or three distinctive features (far change). To investigate the issue of tolerance, simulations were first performed on TRACE, an influential model of word recognition, because it could provide actual results. The simulations demonstrated that the model is more tolerant of medial rather than initial mismatches, but the results were mixed concerning the distance of the mismatch. Next, three experiments were conducted. The first experiment, which utilized the phoneme monitoring paradigm, produced suspect results. The second experiment, which utilized the form priming paradigm, revealed that the recognition system is more tolerant of medial rather than initial mismatches, which confirms the results of the TRACE simulations. Similarly, the experimental results were mixed with regards to the distance of the mismatch.
