Na een mailgesprek met David Lichman (de clickerende PNH-instructeur, ik citeer "I believe that Parelli has moved dramatically towards positive reinforcement using food rewards - especially in the case of what they metaphorically call the Left Brained Introvert horse... the horse that doesn't really want to move his feet for you, and has the "What's in it for me?" attitude. Punishing or using negative reinforcement more violently often makes things much worse with these horses.") dacht ik terug aan onderstaande test.
