According to the data of a psychodiagnostic study 52 unilateral right-handed men have shown correlation of a dominant elbow with an individual style of emotional responding. These styles correspond to two parameters of personality - "general activity" and "emotionality" in V. D. Nebylitsin's terms. It is supposed that the A. R. Luria test ("arms cross") is an outer marker of the functional dominance of frontal-reticular or frontal-limbic brain structures. Neurophysiological and neurochemical arguments thereof are given.
