Essay - Behaviourism Flashcards
What are the 5 key features of behaviourism
- Learning is viewed as visible, measurable change in behaviour
- Only external events cause change in behaviour and thus learning occurs
- Internal events such as thinking and beliefs cannot be seen and therefore should not be viewed as learning
- Didn’t think processes held in the mind were learning!
- Learning must be observable and measurable called data-based instruction
What are the 4 fundamentals of behaviourism?
- Classical conditioning
- Operant conditioning
- Reinforcement theory
- Punishment in theory
Who came up with classical conditioning?
Pavlov
Describe Pavlov’s experiment?
Studied the saliva of dogs. Found dogs would salivate every time lab assistant who fed the dog entered the room. Same thing happened if anyone else entered the room. Turns out there was a bell attached to the door which rang every time it was opened,
What did Pavlov conclude?
Pavlov found that innate, automated bodily functions could be shaped, changed or conditioned by external interventions
What is an example of contiguous pairing?
Food and bell directly linked to salivation. Even without food dog would salivate
Describe Watson’s experiment?
Little Albert experiment - taught & conditioned little boy to be scared of white rats. Struck a gong and frightened him every time he was shown a white rat.
Where is classical conditioning still be used?
Natural fears can be conditioned to lose the fears.
Use of prisons, torture
What are the limitations of classical conditioning?
Severe limitations as it only applies to automated, classical bodily functions like saliva, sweating, blood pressure
Who developed Operant Conditioning as a theory?
Thorndike.
What was Thorndike’s experiment?
Locked a cat in cage with food just out of reach. Cat starved until it could work out how to open the cage. Used the cats natural behaviour of pawing so it would accidentally open the cage door when it pawed a lever which opened the door. Eventually cat learnt to deliberately paw the lever.
Buris Skinner extended the principles of operant conditioning. How?
Applied it to wide range of animal experiments around WW2. Trained pigeons to peck at lights in sequence, then led to guiding missiles. Similarly we now have guide dogs who assist blind people. The car seat belt alarm is also an example.
What is reinforcement theory
That all behaviours lead to some type of consequences
What is a reinforcer?
Any type of consequence that strengthens the type of behaviour it follows
What is positive reinforcement?
Something that strengthens a behaviour. A desired behaviour is strengthened because a desired stimulus is presented.
