i dont see whats the point though, isnt that just reinforcing good/ desired behavior ? isnt that just positive reinforcement training ?
its more than that - its the whole operand conditioning thing....
so its not just positive reinforcement - although thats part of it.... but its also about punishment as well (Withdrawing things):
Reinforcement, punishment, and extinction
Reinforcement and punishment, the core tools of operant conditioning, are either positive (delivered following a response), or negative (withdrawn following a response). This creates a total of four basic consequences, with the addition of a fifth procedure known as extinction (i.e. no change in consequences following a response).
It is important to note that actors are not spoken of as being reinforced, punished, or extinguished; it is the actions that are reinforced, punished, or extinguished. Additionally, reinforcement, punishment, and extinction are not terms whose use is restricted to the laboratory. Naturally occurring consequences can also be said to reinforce, punish, or extinguish behavior and are not always delivered by people.
Reinforcement is a consequence that causes a behavior to occur with greater frequency.
Punishment is a consequence that causes a behavior to occur with less frequency.
Extinction is the lack of any consequence following a behavior. When a behavior is inconsequential (i.e., producing neither favorable nor unfavorable consequences) it will occur with less frequency. When a previously reinforced behavior is no longer reinforced with either positive or negative reinforcement, it leads to a decline in the response.

its actually really interesting and effective
