Document Summary
Lecture 8 token economies and group contingencies. Individual is given tokens contingent on desired behaviour, which they can trade in for backup reinforcers at a specific time. Tokens are used to represent a reward. The world actually runs on tokens money is the token and it can be exchanged for a variety of backup reinforcers! They can be a variety of items. They are effective because they can be traded for backup reinforcers. Should be given immediately, with some praise so they know why they are being given. Tokens, in and of themselves, have no real value! Toke(cid:374)s (cid:272)a(cid:374) (cid:271)e traded i(cid:374) or (cid:272)a(cid:374) (cid:862)pur(cid:272)hase(cid:863) preferred ite(cid:373)s a(cid:374)d a(cid:272)ti(cid:448)ities backup reinforcers. Exchange period when tokens are handed in for a reinforce. When a child is learning, they should receive the r+ after getting the first token, then this gradually fades and time is increased! Remove a token for undesired behaviour response cost (relatively un-intrusive and easy to administer)
