Cardiac deceleration blockade does not affect reaction time; leaves open its role as a central process marker rather than performance driver.
Does pharmacological blockade of cardiac deceleration affect reaction time performance?
Heart rate deceleration during reaction time tasks is likely a peripheral manifestation of central processes rather than an afferent feedback mechanism facilitating performance.
Obrist et al. (1970) studied this question.
