Subtle threat cues may impair cognition via reduced HF-HRV; hypothesis-generating for environmental effects on autonomic function during testing.
Does viewing a subtle threat cue (the color red) influence HRV reactivity and cognitive performance in participants taking an IQ test?
Viewing a subtle threat cue such as the color red decreases high-frequency heart rate variability, which correlates with worse cognitive performance.
