in the absence of autonomic arousal, behavior that appears emotional will not be experienced as emotional
"In the presence of a barking dog, for example, the sympathectomized cats manifested almost all of the signs of feline rage. Finally, Cannon notes the report of Dana (1921) that a patient with a spinal-cord lesion and almost totally without visceral sensation still manifested emotionality.
For either the Jamesian or the present formulation such data are crucial, since both views demand visceral arousal as a necessary condition for emotional arousal. When faced with this evidence, James's defenders (e.g., Wenger, 1950; Mandler, 1962) have consistently made the point that the apparently emotional behavior manifested by sympathectomizied animals and men is well-learned behavior, acquired long before sympathectomy. There is a dual implication in this position: first, that sympathetic arousal facilitates the acquisition of emotional behavior, and second, that sympathectomized subjects act but do not feel emotional. There is a small but growing evidence supporting these contentions. Wynne and Solomon (1955) have demonstrated that sympathectomized dogs acquire an avoidance response considerably more slowly than control dogs. Further, on extinction trials most of their 13 sympathectomized animals extinguished quickly, whereas not a single one of the 30 control dogs gave any indication of extinction over 200 trials. Of particular interest are two dogs who were sympathectomized after they had acquired the avoidance response. On extinction trials these two animals behaved precisely like the control dogs - giving no indication of extinction. Thus, when deprived of visceral innervation, animals are quite slow in acquiring emotionally-linked avoidance responses and in general, quick to extinguish such responses." (p. 163)
"A line of thought stimulated by the Wynne and Solomon (1955) and the Hohmann (1962) studies may indeed be the answer to Cannon's observations that there can be emotional behavior without visceral activity. From the evidence of these studies, it would appear, first, that autonomic arousal greatly facilitates the acquisition of emotional behavior but it is not necessary for its maintenance if the behavior is acquired prior to sympathectomy; and second, that in the absence of autonomic arousal, behavior that appears emotional will not be experienced as emotional."
