Data were obtained from elite rifle marksmen during baseline and performance conditions (prior to trigger pull) to examine electroencephalographic (EEC) alpha and heart rate (Ilk) patterning. The results were discussed in terms of “response intention” because a trend was found in HR patterning during performance which paralleled that associated with Laceys' (1970) work on selfpaced “key pressing.” Additionally, directional fractionation of the arousal response was evidenced by an increase in tonic MR from baseline to performance which was accompanied by an absence of change in EECJ, Finally, regression analyses revealed a differential relationship of temporal EEC with HR. Specifically, a cardiac “sensitivity” of the right hemisphere was shown by an association between HR and subsequent EEG during the final phase of the marksman's preparatory state. Occipital EEC also appeared to be influenced by cardiovascular activity. These findings extend the generality of the fractionated arousal construct to an intentional and well‐learned motor skill paradigm and question the generality of the activation model.
