Approaches Flashcards
What does the behaviourist approach assume?
That all behaviour is learned , therefore a person is the product of their environment
What do behaviourists argue about the measurement of psychology?
That in order for psychology to be scientific, it should focus on observable behaviour which can be objectively measured, rather than mental processes which can only be inferred
What is classical conditioning?
Learning by association
What are natural reflexes according to behaviourists?
They are made up of a stimulus and response to that stimulus
How is an association formed?
NS –> UCR,
NS + UCS –> UCR,
CS –> CR
What was Pavlov’s research?
Pavlov’s dogs: noticed that dogs began to react to stimuli that coincided with food (a bell on the door) and started to salivate before any food arrived
What is operant conditioning?
learning by consequences
What does operant conditioning suggest?
that reinforcement and punishment shape our behaviour
What is reinforcement?
Anything that has an effect of increasing the likelihood of a behaviour being repeated
What is positive reinforcement?
If a behaviour has a pleasant consequence, it increases the likelihood of the behaviour being repeated
What is negative reinforcement?
If a behaviour results in the removal of something negative, it increases the likelihood of that behaviour being repeated
What is punishment?
If a behaviour results in unpleasant consequences, it DECREASES the likelihood of that behaviour being repeated
What are the two types of reinforcement schedules?
continuous: behaviour is continually rewarded to establish a behaviour
variable: behaviour is sometimes rewarded to maintain the behaviour
What was Skinner’s research?
Skinner box: controlled environment allowed him to manipulate rat’s behaviour (reward it with food for pushing a lever, punish it with electric shocks for other behaviour)
What are the strengths of behaviourism?
It is scientific and testable- supported by research (e.g. Skinner and Pavlov)
it has real life applications: if you know how behaviours are formed you can undo them through counter-conditioning (e.g. systematic desensitisation)
What are weaknesses of the behaviourist approach?
It takes a mechanistic view of behaviour and relies heavily on animal studies
What is extinction?
When the CR declines and disappears because the CS is continually repeated in the absence of the UCS
What is spontaneous recovery?
Where the CR reappears in a weakened form in response to the CS
What is generalisation?
When stimuli similar to the CS produce the CR
What is another study into classical conditioning?
Little Albert study: Where little Albert was taught to fear rats through association with loud noises, he then generalised this to all white fluffy objects
He was similarly taught to fear buttons, however this fear was harder to teach and less long-lasting suggesting evolutionary preparedness
What does the cognitive approach focus on?
informational processing (of course this still affects behaviour but their focus is much more on these mental processes)
What are the key mental processes?
Memory, perception and thinking
How do cognitive psychologists study mental processes?
indirectly; by making inferences about what goes on in the brain on the basis of their behaviour. From these inferences they develop theories about internal mental processes
What is a schema?
A package of beliefs and explanations on a topic that come fro prior experience
they can affect behaviour
How are schemas useful?
They help us to take shortcuts in thinking, create a mental framework for information and fill in gaps
we are also born with basic schemas (e.g. motor schema for blinking)
Why are schemas not useful?
They can also lead to faulty conclusions and unhelpful behaviour e.g. negative stereotypes
What two models are used to explain the function of the brain?
Theoretical and computer models
Why is the computer model used?
Both mental processes /the brain and computers are information processors and this processing can be compared
What is the computer model?
It compares how we take information (input) store it or change it (process it) and recall it when necessary (output)
How have computer models helped us?
By understanding how humans process information, store it, and make decisions we can programme computers to show the same ‘human like’ behaviours (Artificial Intelligence)
What is the purpose of theoretical models?
To explain mental processes and make inferences about mental processes
What is an example of a theoretical model?
E.g. the multi store model memory model- a theoretical model used to explain memory
What is cognitive neuroscience?
Where cognition and biological processes are integrated- the scientific study of the influence of brain structures on mental processes
How has cognitive neuroscience aided us?
Advances in brain scanning (PET scan, fMRI scan) means we can now describe the neurological basis of mental processes
It has been possible to work out which parts of the brain are involved in the processing of words
