***p < 0.001; **p < 0.01, *p < 0.05; Low and High Frequency Thresholds are the pure tone threshold constructs that are scaled with a mean of 0, but we present the average threshold for the low (250, 500, 1000 Hz) and high (2000, 3000, 4000, 6000, 8000 Hz) frequency thresholds. Also see Fig. 1 for the range of pure tone thresholds. MCQ, rank of the proportion of delayed reward choices from the Monetary Choice Questionnaire Delay Discounting; prop- proportion; Import- Importance. Frequency and means (std dev) are presented along the top row. ^A smaller proportion value indicates greater delay discounting.
