What does the behaviourist approach include?
Classical conditioning and Pavlov’s research, operant conditioning and Skinner’s research (Skinner’s Box) and types of reinforcement and punishment
What do behaviourists argue that behaviour is learned from?
Behaviourists argue that behaviour is learned through experiences and interactions with the environment
What is a stimulus-response mechanism?
Behaviourists argue that it is only possible to scientifically investigate what can be directly observed and measured. This includes what you do to a creature (stimulus) and the resulting behaviour (response)
What is the rejection of internal mental processes?
The mind CANNOT be directly observed, behaviourists argue it is a ‘black box’, not suitable for scientific study
What is environmental determinism?
Behaviour is the result of experience so it can be predicted and controlled by manipulating the environment
What was Pavlov credited for?
Credited for discovering the process of Classical Conditioning (cc)
What does Pavlov investigate?
The salivating reflex in dogs when he noticed that dogs salivate when certain stimuli appear such as a dog bowl
What is classical conditioning? (Also known as associative learning)
Argues an unconditioned response can be triggered by a neutral stimulus through repeated pairing and eventually the neutral stimulus alone produces the conditioned response
What happens before conditioning?
-Food was an unconditioned stimulus that produced the reflex of salivating which is an unconditioned response
-The bell was a neutral stimulus that produced no conditioned response
What happens during conditioning?
-The unconditioned stimulus of food repeatedly paired with the neutral stimulus of the bell
-The bell becomes associated with the food
What happens after conditioning?
-The bell is now a conditioned stimulus that produces salivating as a conditoned response
Evaluations of Classical Conditioning—— Weaknesses (3)
1.Can be seen as reductionist (exaplins complex phenonma by breaking them down into their simplest, most basic, component parts.)
2.Can be seen as deterministic (the view that all human behaviours and choices are predetermined by prior causes and can be predicted)
3.Can be seen as limited to certain types of learning, works best for explaining reflexes or automatic behaviours
Evaluation of Classical Conditioning——— Strengths (3)
1.Has real-world applications
2.High scientific credibility due to they types of experiments used
3.Focuses on objective and measureable behaviour
What is operant conditioning also known as?
Learning by reinforcement
What is Operant Conditioning?
When a creature performs voluntary responses, it learns from the consequences of those actions.
Consequences that are rewarding reinforce a behaviour so that they are performed more frequently and actions that result in consequences that are punishing are performed less
What did Skinner’s research include?
The Skinner’s Box which was a controlled environment designed to study operant conditioning
How did the Skinner Box experiment work? (Rat treat)
A hungry rat was placed into the Skinner Box without prior training and was free to move around the rat might accidentally press the lever and be given a treat and press the lever again.
How does the Skinner Box experiment work? (Rat electric shock)
A rat was placed into the box where it could receive an eletric shock through cage wires and by pressing the lever the rat avoids the shock resulting in the rat repeatingly pressing the lever
What were the findings from the Skinner Box?
-Behaviour is influenced by the consequences that folllow
-Behaviours followed by rewarding consequences are more likely to be repeated (reinforced), while those followed by undesirable consequences are less likely to recur
What types of reinforcement are there?
Positive and negative
What is positive reinforcement?
Adding a pleasant stimulus to encourage a desired behaviour
What is negative reinforcement?
Is removing an unpleasant stimulus to encourage the behaviour
What does punishment do for behaviour?
Discourages behaviour
What types of punishment are there?
Positive and negative
