Abstract:
:This study addressed whether temporally salient (e.g., word onset) or prosodically salient (e.g., stressed syllables) information serves as a cue to capture attention in speech sound analysis. In an auditory oddball paradigm, 16 native English speakers were asked to ignore binaurally presented disyllabic speech sounds and watch a silent movie while ERPs were recorded. Four types of phonetic deviants were employed: a deviant syllable that was either stressed or unstressed and that occurred in either the first or second temporal position. The nature of the phonetic change (a change from a voiced consonant to its corresponding unvoiced consonant) was kept constant. MMNs were observed for all deviants. In contrast, the P3a was only seen when the deviance occurred on stressed syllables. The sensitivity of the P3a to the stress manipulation suggests that prosodic rather than temporal salience captures attention in unattended speech sounds.
