PAPER 2 - Approaches in Psychology Flashcards
What is INTROSPECTION ?
the examination or observation of one’s own mental and emotional processes.
Who is Wundt ?
- father of psychology
- aim was to examine the structure of the mind
What was Wundt’s APPROACH ?
structuralism
What was Wundt’s TECHNIQUE ?
introspection
What were the 2 major assumptions that introspection were based on ?
(1) all behaviour is seen as being caused (determined)
(2) if behaviour is determined, this it should be possible to predict how human being would behave in different conditions.
What are the 2 WEAKNESSES of Wundt’s introspection technique ?
UNRELIABLE - relied on ‘non-observational’ response - not reliable reproduced by other researchers
NOT ACCURATE - lacks validity - we have little knowledge of the processes behind out behaviour.
What are the 4 psychology goals ?
DESCRIPTION - tells us ‘what’ occurred
EXPLANATION - tells us ‘why’ it occurred
PREDICTION - identify conditions that will cause a behaviour to occur
CHANGE - apply psychological knowledge to prevent unwanted behaviour
What is a STRENGTH of the emergence of psychology as a science ?
reliance on OBJECTIVE SYSTEMATIC METHODS means that theories were tested rather than being accepted as true
What is a WEAKNESS of the emergence of psychology as a science ?
by concentrating on objectivity we may focus more on controlling the situation rather than looking at how people behave in normal situation (ECOLOGICAL VALIDITY)
What are the 5 approaches that explain behaviours ?
THE LEARNING APPROACH: behaviourist and SLT
COGNITIVE APPROACH : point of view of our mind
PSYCHOANALYTIC APPROACH: point of view of our unconscious and early childhood experiences
BIOLOGICAL APPROACH: point of view of genetics
HUMANISTIC APPROACH: point of view of self-image
What is the FIRST ASSUMPTION that behaviourists believe ?
- psychology should be seen as a science
- supported by evidence
- objective and controlled observations
What is the SECOND ASSUMPTION that behaviourists believe ?
- psychologists should study OBSERVABLE BEHAVIOURS
What is the THIRD ASSUMPTION that behaviourists believe ?
- no FREE WILL
- ENVIRONMENT determines BEHAVIOUR
What is the FOURTH ASSUMPTION that behaviourists believe ?
- when we are BORN our mind is TABULA RASA (blank slate)
What is the FIFTH ASSUMPTION that behaviourists believe ?
- little difference in the learning between ANIMALS and HUMANS
- study animals generlaise to humans
What is CLASSICAL CONDITIONING ?
- learning through association
- two stimuli (UCS) + (NS) - repeatedly paired
What are the STRENGTHS of classical conditioning ?
EVIDENCE
- Watson and Rayner
- Little Albert
PRACTICAL APPLICATIONS
- systematic desensitization
- treat ANXIETY of phobias
What is a LIMITATION of classical conditioning ?
DIFFERENT SPECIES, DIFFERENT SURVIVAL NEEDS
- Seligman
- preparedness
- associate if linked with survival
- cc isn’t always implemented
What does the COGNITIVE APPROACH argue ?
internal mental processes should be observed
What involvement do schema’s have on behaviour ?
contribute to how we perceive and have opinions on the world
What are THEORETICAL MODELS ?
- one way to study INTERNAL PROCESSES
- information processing approach
- information flows through cognitive system
What are COMPUTER MODELS ?
- comparing minds to computers
What is COGNITIVE NEUROSCIENCE ?
- how structures affect mental processes
- Paul Broca = frontal lobe affects speech
Name 2 brain imaging techniques
fMRI and PET scans
What do brain imaging techniques do ?
identify activity in specific areas of the brain
What are the STRENGTHS of the cognitive approach ?
USES SCIENTIFIC & OBJECTIVE METHODS
- reliable, objective methods
- enables biological and cognitive approach to come together
- credible basis
USEFUL APPLICATIONS
- explain dysfunctional behaviours
- successful treatment
What is the WEAKNESSES of the cognitive approach ?
COUNTERARGUMENT
- too abstract and theoretical
- artificial stimuli = not represent everyday experiences
COMPUTER MODELS
- different programming between humans and computers
How are twin studies used to determine the likelihood that certain traits have a genetic basis ?
- comparing concordance rates
- concordance rate = extent that both twins share the same characteristics
What is GENOTYPE ?
GENETIC CODE - ‘written’ in the DNA
What is PHENOTYPE ?
BEHAVIOUR and PHYSICAL STRUCTURE - arising from INTERACTION between their GENOTYPE and ENVIRONMENT
What is EVOLUTION ?
change in INHERITED CHARACTERISTICS over SUCCESSIVE GENERATIONS
What is the mechanism behind biological evolution ?
natural selection
How does evolution affect behaviour ?
over successive generations - ADVANTAGEOUS BEHAVIOURS - passed on - widespread
What is ‘SURVIVAL OF THE FITTEST’ ?
characteristics are inherited - compete for resources - those who survive reproduce - offspring have this good traits
How does NEUROCHEMISTRY affect behaviour ?
levels of neurotransmitters affect mood and mood and behaviour
Why do HORMONES do ?
cause PHYSIOLOGICAL REACTION - alerting its activity
Who studied the effects of hormones ?
CARRE ET AL - Canadian ice hockey team
What did CARRE ET AL find ?
- surge in levels of TESTOSTERONE - home stadium - energised players - defending home territory
