Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Phase 1: WIRT Development and Validation Accuracy: Percentage of correctly identified words in the WIRT. Reaction Time: Speed of response to auditory stimuli (ms). Item Difficulty: Performance metrics to refine word difficulty levels. Phase 2: Translation and Validation of Behavioral Measures Listening Effort: Self-reported scores on a 10-question Visual Analog Scale (VAS). Translation Accuracy: Accuracy in translating the EEAS questionnaire. Internal Consistency: Reliability of the EEAS (Cronbach’s alpha). Phase 3: Normative Estimation and Validation Normative Baselines: WIRT performance data from 200 participants. Group Comparisons: Differences in WIRT performance and listening effort between normal-hearing and hearing-impaired groups (27 participants each).Timepoint: Phase 1: WIRT Development and Validation Accuracy: Percentage of correctly identified words in the WIRT.

Secondary
| Measure | Time frame |
|---|---|
| 1. Assess differences in listening effort between hearing-impaired participants & normal-hearing participants using the Word Identification & Recall Test (WIRT) & Extended Effort Assessment Scale (EEAS). 2.Investigate electrophysiological markers during the WIRT task in normal-hearing participants. 3.Investigate electrophysiological markers (e.g., amplitude & latency) during the WIRT task in normal-hearing participants.Timepoint: Measured at baseline & at post-assessment (e.g., 4 weeks & 8 weeks) for group comparisons. Electrophysiological markers recorded during WIRT sessions at specified time points (e.g., baseline & follow-ups). | — |
