what is the DV
what do you expect to happen - 2experimental and hypothesisexperimental hypothesis- lab field or natural (or quasi)
hypothesis (non experimental method used) interview, questionnaire, case study or observation. - 3types of hypothesisdirectional hypothesis- one tailed- one predicted outcome.
non directional hypothesis- two tailed- could be one of two outcomes.
null hypothesis- nothing will happen - 4what three extraneous variables must be controlled?participant variables
situational variables
investigator variables - 5what differences between participants are needed genralisabilityage, gender, mood, ethnicity, expectations, intelligence, personality, memory, attitude, previous experience.

1) perform research
2)write up in full detail
3) aim to get paper published
peer review
1)validates
2) suggests improvements
3)allocate research funding - 26psychology applicationlearning approach behaviourism- treatment of phobias, animal training
learning approach social learning- appropriate role models for children
cognitive approach- improvements to education, computer modelling to artificial intelligence, create things such as lie detector tests
biological approach- understand genetic basis of behaviour, evolution of behaviour, effects of hormones and develop drug theories - 27designing a research study AMVE SEMPAAims and hypothesis
