Assessing Perceptual Effects of Interactive Tasks
Purpose
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.
Condition
- Amyotrophic Lateral Sclerosis
Eligibility
- Eligible Ages
- Between 18 Years and 65 Years
- Eligible Sex
- All
- Accepts Healthy Volunteers
- Yes
Inclusion Criteria
- passing the remote hearing screening - having no known speech, language or neurological disorders per self-report - being a native monolingual speaker of American English - having no experience communicating with people with dysarthria - being between the ages of 18 and 65.
Exclusion Criteria
- None - if volunteer meets the inclusion criteria, then they will be enrolled

- Allocation
- N/A
- Intervention Model
- Single Group Assignment
- Intervention Model Description
- 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.

Detailed Description
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.
