Interventions
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.
