简要总结
In this study, we will evaluate how solo, naive listeners perceive the speech of people with amyotrophic lateral sclerosis (ALS) and age-matched speakers produced across interactive and non-interactive contexts with an unfamiliar, naive interlocutor.
详细描述
Listeners will hear recorded speech of PALS and age-matched speakers and indicate what they heard. Recorded speech consists of vowels and consonants produced in non-interactive and interactive tasks. The perceptual judgements will be compared to see whether interactive contexts have similar perceptual effects across the two groups.
Plans for Assignment - This is a single group study in which all participants will engage in the same tasks.
Delivery of Intervention: Solo listeners will participate in this study in a remote, asynchronous format. They will be recruited using the online participant recruitment platform Prolific © and will use their own laptop/computer and headphones.
Adequacy of Sample size: We will use n = 1300 listeners to achieve 80% power at alpha of .05 to detect between group differences with the assumption of medium effect sizes (Cohen's f = 0.3).
Adequacy of Analyses: The proposed statistical analyses (Generalized mixed effects regressions) are standard and will be used to analyze the effect of the intervention on the outcome measures described below.

研究组 & 干预措施
Listener Perception of Speech Produced in Different Task Settings
Listeners will hear recorded speech of PALS and age-matched speakers produced within interactive and non-interactive contexts and indicate what they heard.
干预措施: Listener judgements of speech produced in different tasks (Behavioral)
结局指标
主要结局
Intelligibility of recorded speech
时间窗: one 20 minute session
Perceptual judgments will be provided by solo, naïve listeners who did not participate in the interactions. Listeners will hear recorded speech of PALS and age-matched speakers recorded across the different tasks and indicate what they heard. The score will be expressed in percent. The possible range is between 0-100%. The higher scores mean a better outcome.
