Interventions

  • Listener judgements of speech produced in different tasks — BEHAVIORAL
    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.

Study Details

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.
