Does heart rate and cardiac phase influence visual perception?
Heart rate and cardiac phase (specifically the P wave) appear to influence visual perception, suggesting a role for cerebral perfusion in perceptual performance.
Sandman et al. (1977) studied this question. Heart rate and cardiac phase vs. Different heart rates (low, middle, high) and cardiac phases was evaluated on Tachistoscopic recognition task performance. Low heart rate and stimulus presentation during the cardiac P wave enhanced visual perception performance, particularly during the fastest exposures.
