Approaches in psychology Flashcards
(113 cards)
Who was Wilhelm Wundt?
opened the first ever lab dedicated entirely to psychology in 1879
What is the ‘scientific method’?
-assuming that all behaviour is determined and therefore it should be possible to predict human behaviour in different controlled conditions.
What were the 3 investigative methods used by Wundt?
-objective= not influenced by personal feelings/opinions
-systematic= done according to a methodological plan
-replicable= ability to reproduce results
Introspection definition
‘looking inwards’
-first systematic experimental attempt to study the mind by breaking up conscious awareness into basic thoughts, images and sensations.
Introspection in action
(aim and procedure)
-wanted to develop theories about mental processes
-trained his graduate researchers to make personal observations of how he and his co workers reacted to different stimuli they were presented with i.e a ticking metronome
-analysed using structuralism= isolating structure of consciousness, done by using same stimuli
Evaluating Wundt
controlled environment(scientific)
-methods were systematic and well controlled i.e introspection recordings in a lab
-standardised procedure reduces extraneous variables
-forerunner for other approaches
Evaluating Wundt
subjective data
-relied on ppts self reporting their mental processes which would be influenced by perspective
-ppts may have hid some thoughts
-hard to use data to predict future behaviour(an aim of science)
Evaluating Wundt
supporting research
-contemporary studies have used introspection
i.e Griffiths(1994) asked gamblers to think aloud while playing a fruit machine, to see if its different to non gamblers(upon analysis they were)
Evaluating Wundt
Wundt’s contribution
-produced the first academic journal for psychological research + 1st textbook
-set foundation for future approaches
The emergence of psychology as a science
1900s behaviourists
-introspection questioned by John B Watson + BF skinner due to subjective data and difficulty to establish general laws
-proposed that psych should only study what should be objectively measured/observed
The emergence of psychology as a science
1950s cognitive approach
-digital revolution influenced psychologists to liken the mind to a computer i.e MSM
-tested predictions about memory + attention using experiments
The emergence of psychology as a science
1980s Biological approach
-taken advantage of advances in tech to investigate physiological processes i.e fMRI and EEG to study live activity in the brain/ genetic testing to understand relationship between genes and behaviour
Evaluation of the emergence of psychology as a science
modern psychology
-can claim to be scientific as they all use scientific methods + discipline to fulfil aim of learning and understanding behaviour i.e controlled lab studies
Evaluation of the emergence of psychology as a science
Subjective data
-humanist approach rejects scientific approach, focussing on individual experiences.
-active ppts in research can respond to demand characteristics so study of human thought may not always be possible
Evaluation of the emergence of psychology as a science
lack of a paradigm
-Philosopher Thomas Kuhn said that any science must have a paradigm(set of principles that all in the field agree on)
-said psych is not a science because it does not have a paradigm at its core
What is the behaviourist theory?
-interested in studying behaviour that can be observed not mental processes like introspection.
-objective and controlled research i.e lab studies
-believes that babies are born ‘tabula rasa’ and we all(even animals) have the same basic processes that govern learning
Assumptions of the behaviourist approach
-not concerned with ‘irrelevant’ mental processes of the mind
-John B Watson(1913) rejected introspection due to vague concepts
What are the 3 ways of learning?
-learning through consequence(operant conditioning)
-learning through imitation(social learning theory)
-learning through association(classical conditioning)
Classical conditioning
-passive process of learning by association
-only a UCS can trigger a UCR(naturally occurs)
-A NS would not trigger UCR
-only in the UCS presence, the NS would be associated to the UCS and would trigger a UCR
-over time, the NS= a CS and would trigger a CR on its own
Classical conditioning-
Pavlov(1927)
-dogs could be conditioned to salivate at sound of a bell by repeatedly serving food after the sound.
-gradually, they learned to associate the bell with food and would produce saliva at the sound
-showed that a neutral stimulus can become a learned/conditioned response via association
definition of punishment
consequence of behaviour that decreases likelihood of behaviour repeating
Operant conditioning
-Skinner(1958) suggested learning is an active process whereby humans and animals can operate on their environment. Behaviour is shaped and maintained by its consequences i.e reinforcement and punishment
Reinforcement and punishment
-REINFORCEMENT:
+, receiving a reward when a certain behaviour is performed(physical or intrinsic i.e good feeling)
-, avoiding/removal of something unpleasant by performing behaviour as encouragement
-PUNISHMENT:
+, receiving an unpleasant consequence after performing a behaviour
-, removal of something pleasant after a behaviour
B.F Skinner’s research(1953)
-placed rats in controlled environment(box)where he could manipulate stimuli
-the hungry rat would first accidently knock the lever and receive a food pellet.
-rat would learn if they press the lever they received food.(+ reinforcement)
-rat was subjected to an uncomfortable shock and would knock the lever by accident and turning it off
-rats learned that when the current came on they had to press the lever to remove it.
