Week 8: Operant (instrumental) conditioning Flashcards
What did the research of Edward L Thorndike involve?
Testing problem solving on cats in puzzle boxes.
What is the law of effect?
Behaviour that produces a positive outcome will be more likely to be repeated.
Behaviour that produces a negative outcome will be less likely to be repeated.
Skinner pioneered research on operant conditioning using a device called…
The Skinner Box - a lever pressed = a pellet dropped
What was the Skinner box used to research?
the learning of associations between behaviour and consequences.
Reinforcement can be positive or negative, explain
Positive reinforcement - something given that is pleasant
eg. press bar = pellet
Negative reinforcement - Something is removed that produces a pleasant outcome
eg. remove electric shock when bar is pressed
Punishment can be positive or negative, explain.
Positive punishment - something is presented that is unpleasant
eg. lever pressed = electric shock
Negative punishment - something is removed which produces an unpleasant feeling
eg. rude child = take away pocket momey
What is the most effective type of reinforcement?
Positive reinforcement
During reinforcement, the consequence is…
Pleasant
During punishment, the consequence is…
Unpleasant
What is shaping and give an example from Skinner’s box?
the reinforcement of responses that are closer and closer to the desired response.
eg. approach the bar = seed given
touch the bar = seed given
press the bar = seed given
What type of reinforcement or punishment is being shown:
Rat presses lever = food given = tendency to press lever increases
Positive reinforcement
What type of reinforcement or punishment is being shown:
Rat presses lever = electric shocks stop = tendency to press lever will increase
Negative reinforcement
What type of reinforcement or punishment is being shown:
Rat presses lever = shock given = tendency to press lever decreases
Positive punishment
What type of reinforcement or punishment is being shown:
Pigeon pecks at disc = loud noise = less likely to peck at noise
positive punishment
What type of reinforcement or punishment is being shown:
A`parent taking away a child’s ipad following bad behaviour
negative punishment
What type of reinforcement or punishment is being shown:
A child tidies her room and is immediately praised by her parents
positive reinforcement
What type of reinforcement or punishment is being shown:
An alcoholic who takes the drug Antabuse gets violently ill after drinking beer
positive punishment
After being rude to his mother, a boy is not allowed to go to a party.
negative punishment
If a child asked her mother for a chocolate when they went shopping, and the child asked her father for a chocolate on the next shopping trip, what concept is being demonstrated?
Stimulus generalisation
When a dog begged, his owner gave him a treat. The owner no longer gives him treats.
What concept is being demonstrated?
Extinction
