The Learning Approach Flashcards
What is the learning approach
An umbrella term for a group of theories which emphasise the importance of learning
-behaviourism (operant and classical conditioning) and social learning theory
What do behaviourists believe
- psychology should be seen as a science
- theories need to be supported by evidence through objective and controlled observation
- psychologists should only study observable behaviour
- people have no free will and environment determines behaviour
- when born we are a blank slate (tabula rasa)
- little difference in learning in humans and animals
Behaviourist approach- classical conditioning
Leaning via association when two stimuli are repeatedly paired together (ucs and ns)
The neutral stimuli eventually produces the same response as the unconditioned stimulus
Classical conditioning - Pavlov
Before conditioning
Food (UCS) —> salivation (UCR)
Before conditioning
Bell (NS) —> no salvation -no CR
During conditioning
Bell + food —> salivation(UCR)
After conditioning
Bell (CS) —> salivation (CR)
What did Pavlov’s dogs learn
To associate the sound of a bell with food and salivate even without food and just a bell
-a neutral stimulus can elicit/produce a new learned/conditioned response
Other features
Extinction- after a few presentations of the CS (bell) without the UCS (food) it looses its ability to produce the CR (salivation)
Stimulus generalisations- Pavlov also discovered that one can animal has been conditioned they will respond to stimuli that are similar to the CS
Evaluation of classical conditioning - supporting studies
Watson and Rayner- little Albert had originally no fear of various stimuli (rat , rabbit etc) though was startled by a loud hammer noise
The white rat was presented and then the noise which was repeated
Through classical conditioning he learned to fear the rat without the noise
Illustrates how phobias can form through classical conditioning
Evaluation of classical conditioning
:) - practical application- lead to treatment of anxiety associated with phobias SD - replace anxiety with relaxation
:( - different species face different challenges to survive so have different capabilities to learn through CC
Seligman- animals are prepared to learn association for survival
CC is not always easily implemented
Behaviourist approach- operant conditioning
Skinner believed that the best way to understand behaviour is it’s consequences- can influence whether a behaviour is more/less likely to be repeated
Reinforcement
Something in the environment that strengthens a particular behaviour
- more likely to occur
Positive reinforcement
Increases likelihood that behaviour will be repeated
- produces a consequence that is pleasant eg praise
Negative reinforcement
Increases likelihood a behaviour will be repeated
Removing something unpleasant eg hitting the off button on an alarm to remove the unpleasant noise
Punishment
Decreases likelihood of a behaviour being repeated
Unpleasant consequence of behaviour
Eg a detention
Skinners research
Rats and pigeons
Put on a skinners box
Positive reinforcement -Associated pressing a lever with getting rewarded
Negative reinforcement-Pressed a lever to avoid electric shock
Getting an electric shock- punishment
Operant conditioning evaluation
:) - empirical support with Skinner’s research using an experimental method
Skinners box to manipulate the consequences of behaviour (IV)
Effect on rats/pigeons behaviour (DV)
Establish cause and effect between the consequences of behaviour and the likelihood of it being repeated
