TABLE III.

Results of rank-based, mixed-effects regression relating the electrode yielding the worse threshold in experiment 1 to sensitivity of the pair in experiment 2. Dependent variable was sensitivity in d′ units. Categorical variables were coded as 0–1. The value represented by each estimate is shown in parentheses beside the name of the variable. p-values were calculated using the normal distribution (as opposed to t-distribution) by default in the rlme package in R.
