A favorite snack is given for a positive response. The best way to start this procedure is with objects not normally ingested. Once the command is learned, new inedibles are introduced. This procedure is gradually extended to having the client hand over preferred objects. At this point the client begins to be token-trained.
Tokens are redeemable for a favorite snack.
Gradually, the number of tokens are reduced. At this point the trainer also introduces to the client tokens for other positive behaviors in addition to turning over inedibles.
