Results of regression analyses using six different models: one model with a single predictor for each of the sensory modalities and a sixth model containing all five predictors together. This analysis was performed once with the total raw scores (i.e., sum of low- and high-threshold items) and again with the low- and high-threshold items separately. F stats, p values, and adjusted R² are presented for each model. Italics indicate significant after Bonferroni correction (p < 0.01)
