Abstract

This paper presents the results of an experiment examining the effects of position of lexical stress on response latency in trained picture naming. Stimuli comprised matched lists of disyllabic words where lexical stress fell either on the initial (SW e.g., 'banjo) or final syllable (WS, e.g., balloon). Following training, participants were required to name the pictures in two conditions — speeded and delayed. Response latency was determined by handmarking the acoustic onset from a digital recording of the response. Analyses revealed an interaction between stress pattern and naming condition: Stress pattern influenced immediate naming latencies, but did not influence delayed naming latencies. Words with stress on the second syllable were produced more slowly in the immediate naming condition. This pattern of results excludes the source of a lexical stress effect at an articulatory level and is consistent with a theory where lexical stress influences retrieval and encoding of phonology. Theoretical accounts of these data will be discussed, and these data related to earlier accounts of effects of lexical stress on reading (Rastle & Coltheart, 2000). [ABSTRACT FROM AUTHOR]
