Caption: Conditioned by the ringing of the bell.
As I study this image, it seems that woman and beast are both, in their own way, waiting for the bell to ring. The woman gazes up expectantly while the primate patiently bides his/her time. Like Pavlov's dog, both have been programmed to have a particular reaction when they hear the tolling of the bell. Pleasure or pain? Reward or torment? They must wait to find out.
