I didn't mention a conditioned aversive stimulus. My general psychology prof made it clear that it is impossible to condition a stimulus! However, we know that animals are capable of timing, so that an emotional response could vary in a time-dependent manner. Unsignaled avoidance isn't a problem (or at least it wasn't in my dissertation 20 years ago).
