"Pavlov's symptom is a sign of catatonic stupor: the patient answers a question or performs some action only after being addressed in a quiet voice, but does not respond to a similar address made in a normal or loud voice. Moreover, such patients often answer questions with a negative connotation. Patients who are in a stupor during the day begin to move, talk, and eat at nightfall." - https://en.wikipedia.org/wiki/Nobel_Prize_in_Physiology_or_Medicine
