Did you know that…..
Pavlov established the concept of “conditional reflex“?
He noted that a laboratory dog responded to his approaching step, as to the meat which frequently accompanied his arrival.
Pavlov found that if a tuning fork were sounded when meat was supplied, the dog would come to respond to the former in the absence of the latter; that is, salivary reflexes could be attached to an originally ineffective stimulus (tuning fork) on condition that it accompanied the native stimulus (meat) for this response.
