Sponsor: Penn State University
Summary
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?

Interventions
Structured Communicative Interaction
Two interlocutors, one with ALS and a typical, unfamiliar interlocutor or an age-matched speaker and a typical interlocutor, will work together. On each trial, one of the interlocutors will be randomly chosen to be the "speaker" and the other will be the "listener". Each participant in the pair will view the same set of words on their screens. After one second, one of the words will be highlighted on the speaker's screen, they will say the word in the phrase "Click on the \_\_\_\_ this time", and the listener will click on it. After the listener has made their selection, both participants will receive feedback on trial success.
Clear Speech
PALS and age-matched speakers will read critical words consisting of target segments (e.g., "hid", "ship", "net") in random order four times. These words will be embedded in the carrier phrase "Click on the \_\_\_ this time." Participations will be instructed to overenunciate the critical words.
Unstructured communicative interaction
Two interlocutors, one with ALS and a typical, unfamiliar interlocutor or an age-matched speaker and a typical interlocutor, will work together. The pairs will be presented with two different versions of the same picture with eight differences chosen to elicit the same target segments (e.g., "hid", "ship", "net"). These pictures will be modified from the LUCID corpus. In total, pairs will complete four picture sets per session. Pairs will be given 5 minutes for each picture set.
