Approaches Flashcards
Wundt and introspection
Set up first psych labs in 1870s
Introspection : systematic analysis of your own conscious experience of a stimulus
1) focus on stimulus
2) reflect on different mental processes
3)description of inner processes
4)compare different participants
Emergence of psychology as a science
Empirical approach through direct experience
Pavlov and skinner developed behaviourist approach - observable learned behaviour
Rise of cognitive in 60s saw study of mental processes more scientific
1980s - biological approach - advances in tech e.g. fMRI and EEGs
Behaviourist approach
Stimulus-response learning
Classical conditioning - Pavlov - learning by association with dogs
Operant conditioning - Skinner - learning by reinforcement with rats in ‘skinner boxes’
Positive reinforcement - treat when press lever
Extinction - treats stop so rats stop pressing lever
Negative reinforcement - perform same behaviour to avoid mild electric current beneath feet
S - behaviourist
STRENGTH
Observable and measurable
Highly controlled
Empirical evidence
P - behaviourist
STRENGTH
Systematic desensitisation- successful phobia treatment
McGrath - 75% success
R - behaviourist
WEAKNESS
Reduces human behaviour down to specific variables
Environmental - no biological E.g. twin studies
Requires more holistic
E - behaviourist
WEAKNESS
Animal studies e.g. Pavlov and skinner
Humans may be able to control behaviour more effectively in response to external factors
Limited in ability to explain human behaviour
D - behaviourist
WEAKNESS
Environmental determinism - factors outside of control
Doesn’t explain why we all react differently to same environment e.g. two people experience similar frightening experience, won’t both necessarily develop phobia
Ignores free will
Social learning theory
Bandura - learn indirectly through observation and imitation
Vicarious reinforcement
Identification and modelling - possess similar characteristics, attractive, high status
Mediational processes - attention, retention, reproduction, motivation
Bobo doll experiment
Aim - see if role models influence behaviour
Procedure - half shown aggressive and other half shown non-aggressive and then taken to room with toys and behaviour rated on scale of aggression
Findings - half shown aggressive reproduced aggression onto bobo doll whereas those shown non-aggressive didn’t show aggression
Also greater imitation when model was same gender
Conclusion - aggressive model leads to aggressive behaviour - level of imitation affected by characteristics
S - SLT
STRENGTH
Observable and measurable
E.g. Bandura bobo doll was highly controlled
Empirical evidence
HOWEVER
Mediational processes can to be observed and must be inferred
P - SLT
STRENGTH
Concepts like identification and modelling used to encourage positive behaviour
Pro social ads e.g. anti alcohol
R - SLT
STRENGTH
Incorporates internal cognitive factors and how they interact with environment
E.g. identification and modelling
May still ignore biological however it is more holistic than behaviourist
E - SLT
WEAKNESS
Influenced by demand characteristics
E.g. argued that main purpose of bobo doll is to strike it
May be based on flawed evidence
D - SLT
STRENGTH
Less determinist than behaviourist - doesn’t suggest that behaviour is caused totally by factors outside of control
Do have some ability to mediate
Middle ground between determinism and free will
Cognitive approach
Internal mental processes - studied indirectly by making inferences
Theoretical and computer models e.g. MSM
schema - mental frameworks of ideas or expectations developed through experience - act as shortcuts but can distort interpretations of the world with stereotypes
Cognitive neuroscience - scientific study of the biological structures and functions that underpin cognitive processes - fMRI and PET scans e.g. Tulving LTM
S - cognitive
STRENGTH
Observable and measurable
E.g. lab experiments and emergence of cognitive neuroscience enabled researchers to infer cognitive processes
Empirical
HOWEVER
Inferences could be mistaken
P - cognitive
STRENGTH
CBT - March - just as effective as drugs when treating depression
Cognitive neuroscience - localisation of function e.g. memory
