Table 1.
Threat | Safe | |
---|---|---|
Skin conductance change (µSiemens) | 0.10 (0.03) | 0.00 (0.02) |
Heart rate change (beats per min) | −0.95 (0.42) | 0.13 (0.38) |
Corrugator EMG change (µV) | 0.58 (0.20) | −0.06 (0.14) |
Inspiratory volume (ADU) | 74963 (2680) | 77739 (4189) |
Mean (SE) for each dependent measure as a function of cue type. Values reflect changes in skin conductance, heart rate, and corrugator electromyographic activity relative to a 1-second pre-cue baseline. µV=microvolts; ADU= analog-to-digital units.
