Evaluating Verbal Communication in Structured Interactions: Theoretical and Clinical Implications

"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."

"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."

"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."
