PSYC*2330 Lecture 15 (Week 7)
S(stimulus) - R(response) -> Ri (Reinforcers) = I (Primary Reinforcer), Conditioned
Reinforcers or Social -> stamp in the relationship between the stimulus and response
Maintaining Behaviour
- once a behaviour is practiced and introduced then you can start changing the
frequency of responses
- Important assumption of behaviour modification: There are sources of reinforcement in
the natural environment that will maintain the desired behaviour if only it can be
established initially
Tactics for Encouraging Maintenance
1. Partial reinforcement
- start with fixed schedules then must switch to partial
2. Reinforcing a variety of settings
- encourage generalization - wanted behaviours have to be generalized
- if youʼre trying to change the behaviour youʼre going to reinforce it in a lot of settings
3. Fading
- at that point you start to fade out the reinforcers in a way that the person is not super
conscious of it
- change nature of the conditioned reinforcer
- if you remove too fast all at once, you may stop the behaviour
4. Conditioned reinforcers
- use a combination of primary reinforcers and conditioned reinforcer
- using a conditioned reinforcer is very positive because itʼs easy, cheap
- eventually when the behaviour that is wanted if firmly established, ti doesnʼt have to be
reinforced anymore, certainly not with primary reinforcers maybe CR
Harmful Effects of Reinforcement
- Moral objections - Bribery, Greed
- should be an intrinsic motivation of doing positive behaviours
- if you give rewards all the time they
- a reinforcer is not a prize!! it is something small to make sure that that behaviour is
done, not a complex thing
