Just as I was getting my head around the ‘Training Quadrant’ I came across the ‘Punishment Quadrant’. This is Ian Dunbar’s idea as described in Cesar Millan’s book ‘Cesar’s Rules’. The four quadrants are:- 1. ‘non-aversive, non-punishment’, 2. ‘aversive non-punishment’, 3. ‘aversive punishment’ and 4. ‘non aversive punishment’. Keep up the good work Ian! (I think).
