Approaches Flashcards
Who was the father of psychology?
Wilhelm Wundt
Why was Wilhelm Wundt the father of psychology?
He separated psychology from philosophy and worked in a more structured way
He wrote the first book on psychology
When and where did Wundt open his lab?
Germany in 1879
He aimed to examine reaction times and human consciousness
What method did Wundt come up with for studying the human mind?
Introspection
How do you do introspection?
Participants presented with stimulus
Ask participants to describe their thought process
Results compared
Theories generated
What did introspection form the basis of?
The cognitive approach
Introspection evaluation
Nisbett and Wilson (1977) claim that we have little knowledge of the causes and processes underlying our behaviour and attitudes. This challenges the value of reflective reports in exploring human behaviour.
Still useful - Hunter used introspection to measure happiness in teens. They had to write down their thoughts and feelings at random points through the day when a beeper went off. Found that teens tend to be happy and are more upbeat when doing a challenging task
It isn’t accurate - It is a form of self report technique and therefore affected by demand characteristics
Uses as scientific method. It uses systematic methods, standardised instructions and controlled stimuli
Too subjective - it focuses on non-observable concepts and Wundts results were not replicated by other researchers. It requires inference so other researchers may infer something else
What do behaviourists believe we are born as?
Blank slates (tabula rasa)
Is the behaviourist approach scientific
Yes - it is based off of direct observations in a laboratory
How do behaviourists believe we get info of the world?
Everything is learnt
What similarities do humans and animals have according to behaviourists?
We learn in the same ways
What is conditioning?
A term used for learning
What are they 2 types of conditioning?
Classical and Operant
What are the stages of pavlov’s classical conditioning
Neutral stimulus —> No response
Unconditioned stimulus —> Unconditioned response
Unconditioned stimulus + Neutral stimulus —> Unconditioned response
Conditioned Stimulus —> Conditioned response
What are some features important to classical conditioning?
Timing - unconditioned and neutral must be at the same time
Extinction - Learnt behaviour lost if not repeated
Spontaneous recovery - Behaviour can be learnt again if UCS and NS are repaired
Stimulus generalisation - Learnt behaviours can be generalised to other things e.g. rats/rabbits in the little albert study
Who proposed operant conditioning?
Skinner
What does operant conditioning refer to?
Learning from the consequences of your behaviour
What is positive reinforcement and punishment
Reinforcement - Something added that increases behaviour
Punishment - Something added that decreases behaviour
What is negative reinforcement and punishment
Reinforcement - Something taken away that increases behaviour
Punishment - Something taken away that decreases behaviour
What are the 2 schedules of reinforcement?
Continuous
Intermittent
What’s continuous reinforcement?
Behaviour is continuously rewarded every time - behaviour is learnt quickly but won’t last
What is intermittent reinforcement?
Behaviour is rewarded occasionally - Longer to learn bust lasts longer
What was the Skinner box?
Skinner created a special cage called a ‘Skinner box’ to test operant conditioning in rats (and sometimes pigeons). The rat moves around the cage and when it accidentally presses the lever (or pecks a disc in the case of a pigeon), a food pellet falls into the cage. The hungry rat very quickly learns that it can get food by pressing the lever.
Behaviourist approach evaluation
Makes use of an empirical method - rejected introspection and instead focussed on measurable and objective behaviour. This makes research more valid which leads to more funding
Use of animal studies - behaviourists believe animals learn in the same ways as humans - gives researchers more control over demand charactersitics - can be considererd unethical and lack generalisability to humans e.g. skinners rats doesnt tell us mutch about humans
Very deterministic - we have no free will. It ignores biology and is therefore reductionist. Maybe better to use a more holistic approach
Conditioning useful in exmplaining and treating phobias e.g. systematic desensitisation for people with phobias. The patient is conditioned to association their phobia with relaxation instead of fear. C.A. cant explain why people cant always recall traumatic experience
How does SLT propose we learn?
Through the observations of others
We observe then imitate
What is vicarious reinforcement?
Watching others behaviour be rewarded or punished?
What makes imitation more likely?
Observed the consequences of that behaviour
Identify with the role model
Confidence to reproduce the behaviour
What are the 2 types of role models? What do they mean?
Symbolic - Someone portrayed in the media
Live - Someone who we have direct contact with
What are the 4 meditational processes
Attention - pay attention to actions and consequences
Retention - Observed behaviour stored in LTM
Reproduction - Must be able to reproduce the behaviour
Motivation - The individual must expect to be rewarded
Bandura
66 nursery kids
3 conditions
1) Video where adult rewarded for hitting doll
2) Adult punished for hitting doll
3) Nothing happened hitting the doll
1. was most aggressive
2. was least aggressive
When 2. were offered a reward to be aggressive, they quickly were
Bandura evaluation
High internal validity - lab study so extraneous variables controlled
Only looked at immediate effects, we don’t know if this would last
Heard in video - that’s the bobo doll for hitting
Siegel and McCormick
Young people who hold deviant values and attitudes are more likely to associate with similarly- inclined peers because they are more fun to be with, and thus the reinforcement of ‘deviant’ behaviour is a two-way process and not necessarily the result of SLT itself.
Social learning theory evaluation
Approaches
Issue of causality - do people learn behaviour from role models or do they seek out role models who exhibit bhevaiour they already favour? - Siegel and McCormick
If individuals are predisposed to certain behaviours, suggests behaviours arent learned through social interactions but pre existing inlclinations
Cook & Mineka (1990) had monkeys watch a video of another monkey reacting with fear to a snake. When the observer-monkeys had a chance to get food, they would not if it involved approaching a snake or a snake-like object (toy snakes). C.A - may be evolutionary
Research is scientific, being carried out in lab conditions and using one-way mirrors and multiple observers for inter-rater reliability. C.A - brings in cognitions – thought processes, which are unobservable.
Ignores biological factors e.g. the role of testosterone in aggression. The aggressive boys in Banduras study may have had high levels of testosterone explaining their violence
What is the cognitive approach
Studying internal processes
How do psychologists study the cognitive approach?
Scientifically using controlled experiments
What is an inference and why do cognitive psychologists have to make them?
Working out what is happening using available info
Mental processes can’t be directly observed
Therefore inferences made
What do cognitive psychologists do with their inferences?
Make models and theories to explain mental processes
What are schemas?
Packages of knowledge developed through experience
They help organise info
Why are schemas good and bad
Good as they allow us to quickly access large amounts of info and make predictions based off of life experiences
Bad as they can lead to stereotypes and discrimination which has a negative impact on mental health
What are the 2 model types cognitive psychologists use?
Theoretical models
Computer models
What is a theoretical model?
Used by researchers to explain unobserved processes
They describe how info is processed - often with pictures
E.g. the multi store memory model
What is a computer model?
The mind is like a computer
Info is take in via the senses, processed by the brain and then we perform an output
What is cognitive neuroscience?
The scientific study of the influence of the brain structures relating to mental processes
Is built on computer models
What are brain scans like fMRI and PET used for (cognitive neuroscience)
They allow scientists to observe and describe which areas of the brain are involved in mental processes
