Asymmetry in the relationship between finger temperature changes and emotional state in males.

Abstract

Eighty male college students each listened to monaural music that was intended to cause either positive-valence emotions (e.g., happiness) or negative-valence emotions (e.g., unhappiness). When the music was to the left ear, subjects' finger temperature changes during the music correlated significantly with the subjects' ratings of the valence of the emotions they experienced during the music. When the music was to the right ear, finger temperature changes were not different during positive- versus during negative-valence music, and the subjective reports did not correlate significantly with the finger temperature changes. The results are interpreted as indicating that the extent to which males' autonomic responses, such as finger temperature changes, reflect the emotional state of the subject depends upon which cerebral hemisphere is more involved in the processing of the emotion-generating stimulus. Theoretical and practical aspects of this finding are discussed.
