Figure 1.
Response times and errors to easy- and hard-shot decisions when sound was or was not present.
Dark grey bars represent when the sound was present and clear bars when the sound was absent for easy- and hard-shot decisions (A – response time and standard error bars in ms; B – total percentage and standard error bars of decision errors). All differences are significant.
Figure 2.
Cumulative probability distribution for response times pooled across decision type (hard and easy).
Note that even the earliest RTs are affected when sound (grey line) is compared with no sound (black line) conditions.
