Evaluating Verbal Communication in Structured Interactions: Theoretical and Clinical Implications
The goal of this clinical trial is to learn about the effect of communicative interaction on verbal communication in people with amyotrophic lateral sclerosis (ALS) and age-matched speakers. The question is, What are the effects of communicative interaction on verbal communication in people with ALS? Participants will read words and sentences while they are in a solo setting and interactive setting.
