Lecture 1 Flashcards
What are the two major theories of learning?
- Learning by association
Respondent - classical - conditioning - Learning through consequences
Operant - instrumental - conditioning
What is operant conditioning?
- Focuses on the consequences of a behaviour in that context
- Voluntary behaviour in interaction with the environment or context
- The consequences makes the behaviour more or less likely to happen in the future (during the same context)
What is operant learning theory?
- Behaviour followed by a consequence
- The tendency to repeat the behaviour depends on the nature of the consequence, both pleasant and unpleasant
- Focuses on the immediate consequences of a behaviour, less than 60 seconds
- Consequences that occur immediately have the best direct effect on learning, make the behaviour more likely to both happen or not happen
What is a skinner box?
- A controlled experiment to study the impact or patterns of operant learning
The rat Rudolph
Law of effect
The effects of our actions determine whether we will repeat them
- Accidental action can lead to intentional action
Behavioral contigency
Occasion for response
- Its context
Response = Behavior
Consequence
- Immediate
- Outcome of the response
There is a reason why we do something
Gives a tendency or likelihood to repeat that response in the same occasion - because of the consequences it gave
Causal relationship
What is behaviour/response?
- Overt behaviour ; things we can observe
- Covert behaviour ; things we cant observe
Dead man test
If a dead man can do it, it probably is not behaviour
What is consequences of behaviour?
- Something that happens naturally
Hungry - we eat - Constructed from culture or social interactions
joking - laughing - There are 4 basic behavioural contingencies
- Need to have an impact on behaviour
Positive reinforcement
Basic principle
- A response becomes more frequent if a reinforcer, or increase, has followed the response on previous occasions and under similar circumstances
Reinforcement contingency
- Presentation of a reinforcer contingent to a response, resulting in increase frequency of that response
- Positive refers to presenting a stimulus
Example positive reinforcement contigency
Before
-No Instagram
R as in response
- Gets the app
Consequence - Stimulus Reinforcer (SR)
- Notification from Instagram
- Doing a trick for food
- Begging
- Raise hand for attention
- Disruptive behaviours for attention
How to not talk about behaviour
- Dont assume anything from children or animals in terms of, example, expectancy
- Avoid circular reasoning, think of what actually is behind the behaviour - what taught it to happen, what do you get out of it etc
- Whats the immediate consequence of the behaviour?
- Keep things simple
Negative Reinforcement - Escape
Basic principle
- A response becomes more frequent if the removal of an aversive stimulus has followed the response on previous occasions, under same circumstances
Reinforcement contingency
- Removal of an aversive stimulus contingent to a response, resulting in an increased frequency of that response
- Negative refers to reinforcement by removing a stimulus
- What stimulus is aversive depends on the person
Example of escape contigency
Before
- Scary movie on TV
R
- Covering face with my pillow
or
- Changing the channel
SR
- No scary movie in front of me
Avoidance Contingency
- Prevention of aversive stimulus contingent to a response, resulting in an increased frequency of that response
- Sunglasses on before the sun gets in your face
- Wool socks on before youre cold
- Avoiding situations that have been unpleasant in the past (Maintaining anxiety for example -possibly from escape contingencies or respondent conditioning)
- Dysfunctional behavior
