Evoked Response Measures of Resource Allocation: Effects of Primary Task Load.

Abstract

The major emphasis of the research was to assess the utility of employing event-related potentials in monitor type tasks. The 'work manipulation' paradigm was employed. Auditory probes were presented along a secondary channel unrelated to the perceptual-motor task. In the initial study amplitude and latency measures of Wave V of the brain stem evoked potential were measured to auditory probes under conditions of tracking a visual target with a joystick, and just observing the visual display. It was noted that a reduction in amplitude and an increase in latency of Wave V occurred during the tracking task. Although not statistically significant all subjects demonstrated the same effect.
