This research was designed to extend the literature on heart rate variability (HRV) in cognitive performance contexts by examining whether a subtle threat cue (the color red) in a test environment influences HRV reactivity and whether HRV reactivity is associated with change in cognitive performance. Thirty-three participants took an IQ test, briefly viewed red or a chromatic or achromatic control color, and then took a parallel form of the IQ test. High frequency (HF)-HRV (often referred to as respiratory sinus arrhythmia), was assessed before and after the color manipulation. Results indicated that participants who viewed red (relative to a control color) exhibited a decrease in HF-HRV and that decreased HF-HRV was associated with worse IQ performance. These findings demonstrate the sensitivity of HRV as an index of effective and efficient emotion regulation in an achievement context.
