Figure 7. Results of Experiment 4.
A) Mean correct reaction time (RT) as a function of set size for each stimulus type. B) Mean correct reaction time (ms) as a function of steepness. The steepness refers to the time to reach the maximum amplitude from its minimum (or vice versa). Note that 13 ms reflects a square-wave modulation. These data show that auditory driven search requires abrupt auditory and visual events.
