Approaches Flashcards
Origins of Psychology:
Outline Wilhelm Wundt’s work
- Believed that all aspects of behaviour could be studied scientifically
- ‘principles of physiological psychology’ (1873)
- institute of experimental psychology - first experiment
- created approach called ‘structuralism’ (early form of reductionism) and used introspection
Origins of Psychology:
What is introspection
- reflecting on cognitive processes, feelings, sensations and thoughts
- zoning in on a metronome to ‘look into yourself’
- bunch of hippy shit - Keiran Shipperley 2024
- later known as meditation/mindfulness
Origins of Psychology:
What is empiricism
- all knowledge and abilities come from observation and experience alone, rather than being innate
- all behaviour has causes, and is therefore predictable
Origins of Psychology:
what is the hypothetico-deductive model
empirical observations
theory formulation
hypotheses generation
hypotheses testing
repeat
Biological Approach:
what are the assumptions made by the biological approach
- all behaviour is driven by physical or physiological factors
- behaviour is caused by genetic biological or neurochemical factors
- emphasises our nature (internal forces) in shaping behaviour
- most scientific approach
Biological Approach - Evolution and Behaviour:
define evolution
the gradual change within a species over several generations in response to environmental pressures
Biological Approach - Evolution and Behaviour:
define natural selection
the survival of a species due to specific traits - often caused by random mutations
Biological Approach - Evolution and Behaviour:
define adaptive
physical changes to a change in environment or other external stimuli - often mutation caused by the environment
Biological Approach - Evolution and Behaviour:
define Seligman’s 1971 theory
there is a biological preparedness to phobias of certain things. this explains phobias of potentially threatening things such as heights, spiders, snakes etc
Biological Approach - Genes and Behaviour:
define a genotype
genetic constitution of an individual - what genes make up our physical appearance
Biological Approach - Genes and Behaviour:
define a phenotype
occurred behaviour as a direct result of environment stimuli activating genotypes
Biological Approach - Genes and Behaviour:
define an interactionist approach
combination of how nature (biology) and nurture (environment) interact with each other when determining behaviour
Biological Approach - Neuroanatomy:
Outline Raine et al’s study into neuroanatomy
- 1997
- used PET scans on murderers who pleaded not guilty for reasons of insanity (NGRI)
- found reduced activity in parietal lobe (abstract thinking)
- increased activity in occipital lobe (vision)
- reduced activity in corpus callosum
- imbalance between hemispheres
Biological Approach - Neuroanatomy:
What is neuroanatomy
mapping the relationship between various ares of the brain and their functions
Biological Approach - Neuroanatomy:
Give examples of neuroanatomy
Broca’s and Wernicke’s areas
Biological Approach - neurochemistry and behaviour:
What is neurochemistry
all the chemical processes that take place specifically in the brain
Biological Approach - neurochemistry and behaviour:
What is the role of GABA (gamma-amino butyric acid)
- amino acid - primary inhibitory neurotransmitter
- reduced likelihood of reactive response
- reduces brain activity
Biological Approach - neurochemistry and behaviour:
What is the role of adrenaline
initiates fight or flight response
- released by the adrenal module
(see biopsychology)
Biological Approach - neurochemistry and behaviour:
What is the role of serotonin
- ‘feel good’ hormone
- associated with depression, OCD and other mental health disorders
- long lasting hormone
Give evaluations for the biological approach
- research support - Davis et al (1980) looked into the effectiveness of antipsychotic drugs. found relapse occurred 55% of the time when drugs replaced by placebo. 19% when left on medication
- a lot of research conducted on non-humans animals - Harlow and Lorenz
- extremely scientific
- social insensitivity - destined to be ill
- biologically reductionist
- ignorant to cognitive processes
Learning Approach - introduction:
state the assumptions of the learning approach
- all behaviour is learned and we all have the capacity to learn from birth
- tabula rasa - born a blank slate
- extreme nurture side of the nature-nurture debate
- states in order for psychology to be scientific it must only measure observable behaviour - big fuck off to the infamous cocaine addict Freud
Learning Approach - behaviourism classical conditioning:
Outline Pavlov’s research
- 1902
- through association, taught his togs to associate a bell with food
- initially, dogs only produced saliver when given food
- by end, they produced saliver when hearing bell ring
Learning Approach - behaviourism classical conditioning:
outline the processes of classical conditioning
-before conditioning:
unconditioned stimulus (UCS) = unconditioned response (UCR)
- during conditioning:
neutral stimulus (NS) + unconditioned stimulus (UCS) = unconditioned response (UCR)
- after conditioning:
conditioned stimulus (CS) = conditioned response (CR)
Learning Approach - behaviourism classical conditioning:
outline the term extinction in terms of classical conditioning
if the CS is continually presented without the UCS then the CR gradually dies out
Learning Approach - behaviourism classical conditioning:
outline the term spontaneous recovery in terms of classical conditioning
if a CR is not reinforced, it dies out. after a period of rest, the response may suddenly reappear
Learning Approach - behaviourism classical conditioning:
outline the term discrimination in terms of classical conditioning
ability to respond differently to similar but different stimuli
(opposite of generalisation)
Learning Approach - behaviourism classical conditioning:
outline the term generalisation in terms of classical conditioning
responding the same way to similar but different stimuli
generalising one response to to multiple stimuli which are similar
(opposite of discrimination)
think little albert projecting his phobia
Learning Approach - behaviourism classical conditioning:
outline the term one trial learning in terms of classical conditioning
when only one trial is required for the association to take place
conditioning occurs immediately
Learning Approach - behaviourism operant conditioning:
outline Skinner’s research
- 1930
- electric floor
- two buttons, one for food, the other electrocuting the mice
- learnt through positive and negative reinforcement
- switched the buttons round - rats learnt new pattern
- made random or both electric - rats experienced learned helplessness (starved to death rather than risking electrocution)
Learning Approach - behaviourism operant conditioning:
outline primary reinforcers
an individuals natural response to a stimuli
Learning Approach - behaviourism operant conditioning:
outline secondary reinforcers
response to stimuli which is learned/conditioned
Learning Approach - behaviourism operant conditioning:
outline continuous reinforcement
behaviour reinforced all of the time
Learning Approach - behaviourism operant conditioning:
outline partial reinforcement
only reinforced part of the time
