The sympathetic nervous system response to a Continuous Performance Task.

A Continuous Performance Task is an example of a mental stressor which requires vigilance, attention, and effort. We hypothesized that a sympathetic nervous system response would be evident from a resting baseline period to this attention test, and explored if physiological measures were correlated to state and trait anxiety, perceived stress, mindfulness, and performance on the task. In 20 undergraduates, blood pressure and skin conductance increased due to the attention test but heart rate variability did not change. The physiological variables did not correlate to psychological variables; there was a trend of higher perceived stress correlating to lower foil accuracy rate (
