5th International Conference on Spoken Language Processing
In the present study, we examined whether stress constrains the number of activated lexical candidates. In a phoneme monitoring task, we used Dutch carrier words that start in their citation form with a reduced vowel (denoted as @), but which can also be produced with an unreduced vowel. For example, a word such as frequent (meaning frequent) can be pronounced as fr@QUENT or freQUENT. We examined whether mis-stressing these words had an effect on the activation of their lexical representation. Twenty subjects detected a target phoneme (e.g., the 't') in fr@QUENT, freQUENT, FR@quent, or FREquent; stress denoted in capitals. Results showed that target phonemes in words were reacted faster than in pseudowords, but neither stress, nor the nature of the vowel had an effect on the size of lexical effect. This confirms that stress is not part of the lexical input representation.
