The logit scores provided the basis for statistical modeling of the data, which found a significant (p < .001) decline in hit rate for each of the room illumination conditions. These models also provide predictions of hit rate, i.e., the values that fall on the linear regression line, for each of the T3 values within the sampled range. These are shown in parentheses beneath each mean logit value. These predictions are very similar to the observed hit rates that are shown in Fig. 3.
