Exercise-produced arousal, film-induced arousal and attribution of internal state.

Respiration rates were monitored on 20 high-anxious and 20 low-anxious female Ss while they were watching an anxiety-provoking film on industrial accidents. Half of the Ss exercised on a bicycle while half remained seated throughout their viewing of the film. Exercised Ss reported feeling less anxious while viewing the accidents compared with the inactive controls. All groups recalled similiar amounts of the film content, and respiration rates did not increase while viewing the accidents. Results of self-report of anxiety are consistent with a recently advanced theory of objective self-awareness.
