The startle reflex, facial electromyogram (EMG), and autonomic nervous system responses were examined during imagery varying in affective valence and arousal. Subjects (N= 48) imagined affective situations during tone‐cued 8‐strials. Startle blink magnitudes were larger and latencies faster during negatively valent than during positively valent conditions and during high‐arousal than during low‐arousal conditions. Greatest heart rate acceleration and fastest and largest skin conductance responses to ...
