“…The study and several others that I will describe employed eyelid conditioning in the rabbit. The use of the rabbit in this form of Pavlovian conditioning is notable in that it was first accomplished by Ken Goodrich, Len Ross, and me when we were working with Kenneth Spence doing human eyelid conditioning (Goodrich, Ross, & Wagner, 1957, 1959, and was assiduously investigated by Dori Gormezano and his students (e.g., Gormezano, Schneiderman, Deaux, & Fuentes, 1962), so that it is, arguably, the best characterized example of Pavlovian conditioning today. Due to the neurophysiological work of Dick Thompson (1986) and his students, we also have greater knowledge of the neurocircuitry involved than in any other instance of learning in a vertebrate.…”
