A number of investigators have pointed to the importance of non- signal event rates relative to vigilance performance. The purpose of the present study was to investigate the relationship between type of response requirement, task difficulty, and vigilance performance. A response which required greater motor committment was compared to button pressing tasks used by earlier investigations. The difficulty of the task was increased by decreasing the duration of the stimuli.
