Abstract
The cardiac-somatic coupling hypothesis predicts a phasic decrease of general somatic behavior concomitant with a phasic heart-rate deceleration. This hypothesis was investigated during a constant 4 s foreperiod (FP) in a simple auditory reaction-time task. Intertrial interval duration was variable (mean 15.5 s; range 11–20 s). The response was a plantar flexion of the right foot. Besides ECG and EOG, surface EMG of nine striate muscles varying in relevance to response execution was recorded.
In agreement with the hypothesis, heart rate, eye movements, and m. mylohyoideus EMG were decreased at the end of the FP. An increase in the EMG of the agonist m. soleus, antagonist m. tibialis anterior, m. peroneus longus, and m. trapezius was found during the FP. The activity in all other response-irrelevant muscles did not significantly differ from baseline. It was concluded that the results are at variance with the cardiac-somatic coupling hypothesis. Changes in surface EMG are discussed in terms of motor preparation.
