Approaches Flashcards
Falsifiable definition
proposed theory/hypothesis can be found to be false if it is false. Being able to observe and measure variables is key to being scientific. If isn’t possible to test theory, can’t be validated.
Topic link of falsifiability
Authoritarian personality - Milgram disproved it
Objective definition
Something perceived without distortion of personal feelings or interpretation - diminish unconscious bias
How to increase objectivity
Standardised instructions, operationalised definitions of observed variables and physically defined measurements of performance, such as double-blind techniques
Objective topic link
Good objectivity - Milgram
Bad objectivity - Zimbardo
Reliable definition
investigations into theory/hypothesis are replicable under same conditions and when repeated create similar results
Reliable topic link
Strange situation, Milgram
Empirical definition
Controlled measurements/observations based on sensory experiences not thoughts/beliefs. Data collected without bias or expectation from researcher.
Empirical topic link
Jacob’s digit span test
Asch
Milgram
What are the 4 features of science
Falsifiable, objective, reliable, empirical
Wundt’s role in development of psychology
- ‘Father of psychology’ set up first psychology lab in Liepzig, Germany 1870s
- moved psychology towards more controlled research
- promoted use of introspection as way of studying mental processes
- analysed experiences using structuralism
What happened in Wundt’s lab
highly trained observers
presented with carefully controlled and standardised sensory events
asked to describe mental experiences and physical effects of these events
Wundt believed they needed to be in state of high attention and in control of situation
repeated multiple times
introspection definition
the systematic examination or observation of one’s own present and conscious mental or emotional processes
structuralism definition
analysing experience in terms of its two main component parts; physical sensations and emotional feelings. Isolating the structure of consciousness
Wundt strengths
Standardised sensory events
Controlled environment
Repeated multiple times
Only focus on present thoughts as memories aren’t reliable
Trained observers
Led to development of cognitive approach
Wundt weaknesses
Mental experiences ‘non-observable’ lack of empiricism
Subjectivity, depend on person and mood on day
Results varied lots so hard to make general laws - lack of reliability
General assumptions of behaviourism
- All behaviour learnt from environment/upbringing
- Nothing is innate
- Learn via operant and classical conditioning
- What is learnt can be unlearnt
- Same laws apply to animal and human behaviour
Classical conditioning
Learning through association
eg. Pavlov’s dogs / Little Albert
Outline Pavlov’s dogs
Classically conditioned dogs to salivate to sound of bell
Give bone –> dog salivate
Ring bell –> nothing
Ring bell + give bone –> dog salivate
Eventually - Ring bell –> dog salivate
Operant conditioning
Learning via consequences of reinforcement and punishment
Positive reinforcement - give reward for desired behaviour
Negative reinforcement - take away something bad for desired behaviour
eg. Skinner’s rats
Outline Skinner
Skinner box
Rats placed in box with electrified floor, rats had to press lever to get food and turn off electric floor (positive and negative reinforcement)
Rats learnt to pull lever
Found reinforcement more effective than punishment
4 general points for evaluating approaches
ASDA
Approaches to treatment
Scientific merit
Debates
Applications/implications
Behaviourist approach to treatment
Counterconditioning of phobias (classical)
Behaviourist scientific merit
One of most scientific approaches
Focus on observable behaviour and objectivity
Tend to only do lab experiments
