Approaches Flashcards
Define psychology
The study of the human mind and behaviour
What was Wundt’s nickname and why did he earn it?
‘The father of psychology’ as he set up the first experimental laboratory in Leipzig in 1879
What was Wundt’s experiment?
Introspection- participants would focus on something such as a ticking metronome and report their thoughts, emotions,experiences and sensations.
What are the strengths of introspection?
S- high reliability- controlled measures used so procedure can be replicated
S- paved the way for psychology- lead to new approaches like behaviourism that used lab studies.
What are the weaknesses of introspection?
L- highly subjective and unreliable- believed that behaviours can only be measured when observed, which goes against Wundt’s study
L-low reliability- demand characteristics a problem as experiment was conducted in a lab
What are the basic assumptions of behaviourism?
-all behaviour is learned from experience
-behaviour can only be measured through observation
-not concerned with what happens in the mind
-lab studies are used
-animals thought to share the same principles as humans
What was Pavlov’s experiment on dogs research for?
Classical conditioning
How was classical conditioning carried out by Watson and Rayner (1920)
Little Albert the mouse and the hammer
What are the three types of reinforcement?
Positive reinforcement
Negative reinforcement
Punishment
What are two strengths of the behaviourist approach?
S- highly scientific- lab studies were used which are very controlled
S- real world application- used in prisons and psychiatric facilities for reward systems to improve inmates behaviour
What are the limitations of the behaviourist approach?
L- mechanistic view of human behaviour- doesn’t take into account the processes in the mind of a human and their thoughts
L- doesn’t take free will into consideration- skinner said free will is an ‘illusion’ which is too simplistic
L- ethical issues- animals tested on and treated very badly
What is the social learning theory?
The belief that humans learn behaviour through the observation and imitation of role models
What are the two key assumptions of the SLT?
-all behaviour is learned from the environment and genetics play no part
-behaviour is learned from the observation of others behaviour and the reinforcement they receive
What is vicarious reinforcement?
When a person is more or less likely to do something depending on the type of reinforcement somebody else receives from doing that thing
Strengths of the bobo doll experiment
S- children cannot show demand characteristics
S- highly controlled- matched pairs design etc
Weaknesses of the bobo doll experiment
L- sample bias- all participants were white and middle class
L- only tested on a doll so doesn’t replicate real life.
What are the four meditational processes?
Attention, retention, motor reproduction, motivation
What are two strengths of the SLT?
S- can explain differences in cultural behaviours, explains how children take inspiration from role models so they will act like their superiors
S-supporting evidence- cook and mineka showed a monkey a video of a monkey being attacked by a snake and then the monkey wouldn’t approach food if a fake snake was present.
What are two weaknesses of SLT?
L- lab studies- most of supporting evidence done in labs so demand characteristics etc are a problem
L- ignores biological factors- higher levels of testosterone could affect bobo doll experiment
What are the basic assumptions of the cognitive approach?
-focuses on how people interpret information
-looks at internal mental processes to understand behaviour
-thought processes should be studied scientifically.
-thoughts studied indirectly through inferences
What is inference?
Making a logical assumption based of previously known info
What are two strengths of schema?
-helps us to process info quickly
-stop us from being overwhelmed by new environments
What are two weaknesses of schema?
-can distort interpretations of things
-can lead to bias and irrational thinking
What is cognitive neuroscience?
The study of how the brain structure affects internal process, and therefore behaviour
How is cognitive neuroscience carried out?
Using PET and fMRI scans
What are two strengths of the cognitive approach?
S- reliable and objective data- lots of highly controlled lab studies used such as memory tests
S- real world application- used to develop AI and CBT through fixing negative thought patterns to treat depression
What are two weaknesses of the cognitive approach?
L- lab studies used- demand characteristics more of a problem and stimuli used are artificial and lack mundane realism (word lists etc)- relies on inferences which can make it appear too subjective
L- machine reductionism- research shows emotion impacts our ability to process info, this is not considered in the.CA
What are the basic assumptions of the biological approach?
-all thoughts,emotions etc have physical basis
-uses twin studies, blood tests, brain scanning and animal studies
What are monozygotic twins?
Identical twins that share 100% of their DNA
What are dizygotic twins?
Non identical twins that share 50% of their DNA (same as normal siblings)
What is concordance rate?
The rate of probability that two people with the same genes will develop the same organic disease
How can the expression of a genotype be altered?
By environmental factors. For example, skin colour and weight
Why do infants have an innate drive to form attachments?
Evolution- because they are vulnerable so if they form an attachment with a care giver they can be protected
Why do people inherit phobias?
Evolution- come from ancestors who had a traumatic experience as a defense mechanism
What are two strengths of that biological approach?
S- very scientific- PET, fMRI scans and twin studies provide reliable objective data.
S-real world application- lead to medication to help people with schizophrenia and depression
What are the limitations of the biological approach?
L- too reductionist- very simplistic and ignores the role of environment and emotions on behaviour
L- cannot differentiate between nature and nurture- could be argued twins are similar due to being bought up in the same environment
L- ‘criminal gene’ could create problems for society
