简介
Purpose
To investigate the effects of increased syntactic complexity and utterance length demands on speech production and comprehension in individuals with Parkinson’s disease (PD) using behavioral and physiological measures.
Method
Speech response latency, interarticulatory coordinative consistency, accuracy of speech production, and response latency and accuracy on a receptive language task were analyzed in 16 individuals with PD and 16 matched control participants.
Results
Individuals with PD had higher oral motor coordination variability, took a longer time to initiate speech, and made more errors on the speaking task compared with the control group. They also received lower scores on the 2 complex conditions of the receptive language task. Increased length and syntactic complexity negatively affected performance in both groups of speakers.
Conclusions
These findings provide a novel window …
