Assessing Perceptual Effects of Interactive Tasks
Penn State University
Summary
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.
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 participa…

Interventions
- BehavioralListener judgements of speech produced in different tasks
Listeners will hear recorded speech of PALS and age-matched speakers across interactive and non-interactive tasks and indicate what they heard by clicking one of four words displayed on the screen. Standard attention checks and minimum performance thresholds (Theodore, 2021) will be used to ensure that listeners are engaged and are able to provide meaningful perceptual judgments.
