I am conducting a study of changes in the latency of phasic arousal
responses following a treatment protocol for attention disorders in
adults. Currently I am invoking a startle response and then measuring the
time it takes for autonomic phasic arousal to begin as measured by
amplitude rise in the EDR of the left hand. I am not so interested in EEG
measures of arousal. Does anyone have a better idea for looking at phasic
arousal latencies in the autonomic system. HR and BVP are not good
measures of the global arousal mechanism in my mind; however I am open to
suggestion. I have found a correlation between PA latencies and attention
perfomance measures that is fairly predictable.
If you know of any literature of normative latencies with such a measure I
would be most appreciated. My lit search came up almost devoid of
anything meaningful.
