Abstract

This article presents the results of an experiment on spoken word recognition. The study included 19 individuals with Parkinson's disease (aged 60-85 years) and a control group (21 elderly adults without PD and socio-demographically equivalent). The experiment consisted of an auditory lexical decision task. The stimulus material was manipulated in the pre-tonic syllable from which three conditions were obtained: unmanipulated syllable, shortened syllable, and lengthened syllable. Results showed a significant effect of shortened syllable condition and disease on response accuracy. The response time did not reflect an effect attributable to the clinical condition, but it did reflect an effect attributable to the manipulation of the syllable. Syllable duration manipulation proved to be a valid alternative to study auditory word recognition in a clinical population.
