Reinforcement Flashcards
What did E.L. Thorndike discover with regards to reinforcement
Place hungry cat into puzzle box with fish outside, cat opens box with trial and error
Behaviour becomes quicker over time = Law of effect
What is the law of effect
Behaviour followed by a pleasant consequence is more likely to occur again in that situation
Definition of operant
Functioning or tending to produce effects: effective
Are operant behaviours evoked, elicited or emitted?
Only emitted or evoked
What kind of behaviours are elicited
Classically conditioned ones
Operant conditioning aka
instrumental conditioning
What is operant conditioning
Manipulating consequences of behaviour
Characteristics of consequences in operant conditioning
- may increase or decrease beh
- consequence can in itself be a stimulus that leads to another beh
- consequences occur immediately after a beh
Definition of reinforcement
The process in which the consequence of a beh strengthens the beh (more likely to occur (freq), occurs more quickly (latency))
What is a reinforcer
A stimulus, object, or event that strengthens a behaviour, often is an appetitive stimulus
Two types of reinforcement
Positive and negative
What is positive reinforcement? E.g.?
a situation in which a behaviour is followed by the presentation of an appetitive (pleasant) stimulus that increases the behaviour
e.g. I tell a joke -> you laugh = I tell more jokes in the future
What is negative reinforcement? E.g.?
a situation in which a behaviour is followed by the removal of an aversive stimulus that increases the behaviour
e.g. putting up an umbrella -> stops cold rain falling on you = more likely to have umbrella when its raining
Two subtypes of negative reinforcement, explain
Escape behaviour = causes removal of existing aversive stimulus
Avoidance = prevents presentation of aversive stimulus
Natural vs programmed reinforcement
Natural = occurs spontaneously as part of everyday life (e.g. friend laughs when you tell joke)
Programmed = planned and systematic; given as part of a behavioural treatment
Social vs automatic reinforcement
Social = involves another person to deliver reinforcing consequences
Automatic = the individual gets reinforcing consequences directly from the environment (e.g. scratching itch makes it go away)
