What the study is about

This study examines how cochlear implant users understand and comprehend speech in realistic communication situations. Through six experiments measuring listening effort via pupillometry and discourse comprehension, we will investigate how linguistic context, cognitive demands, and processing time affect speech understanding in CI users, and in normal-hearing controls) to identify factors underlying communication resilience versus vulnerability and develop improved, ecologically valid assessment and rehabilitation strategies.

Being studied: Experiment 1: Syntactic and Semantic Context; Experiment 2: False Hearing and Context Overuse; Experiment 3: Two-Sentence Problem; Experiment 4: Cascading Effects on Discourse Comprehension; Experiment 5: Self-Paced Discourse Comprehension; Experiment 6: Clinical Application

Conditions: Cochlear Implant Users
