Abstract
Recent studies have examined the potential role of executive functions (EFs) on the speech communication ability of cochlear-implant, hearing-aid users, and other patients with disordered speech, language, or hearing; in many of the tests used to measure EFs, the stimuli are visual rather than auditory. We developed an Auditory Executive Function (AEF) test battery in which the stimuli consist of word commands (e.g., “quit,” “stop”) spoken either in stern or in lenient voice tone. The battery measures the speed and accuracy of voice-tone classification in four conditions: (1) in the absence of information or response conflict (baseline); (2) while attempting to inhibit potent but inappropriate responses prompted by conflicting ear-laterality information (inhibitory control); (3) while having to switch between incompatible response-mapping rules from trial to trial (cognitive flexibility); and (4) while having to monitor and update the word presented in the current trial and remember the word presented 2–3...
