Autonomic Decoupling in Listening Effort: Why Single-Channel Biomarkers Fail

2026-07-28

Abstract excerpt

<h4>Objective</h4> Current theoretical frameworks operationalize listening effort as a monolithic, unified sympathetic response, driving the search for a single universal clinical biomarker (predominantly task-evoked pupillometry). This study stress-tests the “unified arousal” hypothesis by evaluating the continuous cross-modal overlap of autonomic and cortical responses during a speech-in-noise paradigm. <h4>Des...
