Figure 6.

Effect of the interaction between Cho by stimulus condition by degree of difficulty on cross modal reaction time. Reaction time is reported in milliseconds (ms) on the y-axis. Cho:Cr concentration is reported on the x-axis. Stimulus condition is reported at the top of each panel. Difficulty is indicated by color and shape. The “hard” condition is in red triangles. The “easy” condition is in blue circles. The light blue and red areas reflect the standard error of the mean (SEM) for each difficulty condition.
