approaches in psychology Flashcards
what is the assumption of the behaviourist approach
all behaviour is learnt from the environment
what do behaviourist psychologists study ( and reject )
observable behaviour
reject cognition
what is classical conditioning
learning through association
what are the examples of classical conditioning
Pavlovs dogs
Little Albert
how does classical conditioning work

what is operant conditioning
learning through rewards and consequences
how do rewards help behaviour
reinforces good behaviour increases likelihood of repetition
what are the two types of reinforcement
positive and negative
what is positive reinforcement
the addition of something that strengthens behaviour
what is negative reinforcement
the removal of the unpleasant stimulus which strengthens behaviour
what is punishment
the unpleasant consequence to extinguish bad behaviour
what is an example of operant conditioning
Skinners box
what are the strengths of the behaviourist approach
- real world application and token economies eg schools and prisons
- scientific
- can help people with phobias
what are the limitations of the behaviourist approach
- lacks ecological validity
- unethical
- ignores cognition
what is the assumption of the biological approach
all behaviour is influenced by our genetic makeup and inheritance
what biological factors will affect our behaviour
- genes
- brain
- hormones
- nervous system
how does evolution affect our behaviour
natural selection
weaker genes die out and adaptive genes survive
human behaviours are all similar eg facial expression
what are genetics
genetic makeup of an organism and how genes influence behaviours and characteristics
what is hereditry
traits characteristics and behaviours inhereted by the parents
what is a genotype
actual genetic makeup of a person
what is a phenotype
the physical expression of the gene through environmental interaction q
what studies does the biological approach use
family studies, identical twins, adoption studies
how do psychologists measure if a trait is genetic or learnt from environment
concordance - higher percentage = more likely to be genetic
what are the issues with MZ adoption studies
- very rare
- never get 100% concordance rate
- cannot isolate the role of learning
strengths of the biological approach
scientific
lab based high control
limitations of the biological approach
limited data
lacks ecological validity
Deterministic - crime
what is the assumption of the cognitive approach
that behaviour is driven by internal processes
what is a schema
packages of ideas that hold information
what are the advantages of schemas
allows you to interpret the world
stops you feeling overwhelmed
what are the issues with schemas
could make a perceptual error
what is the human computer analogy
human minds are compared to computer processing
