week 3 slides Flashcards
empirical research
- the systematic investigation of observable phenomena (behaviour, events) in the world
- relies on observable and measurable phenomena
what are the 4 research methods in social psych?
- surveys
- field studies
- content analyis
- experiments
surveys
- popular source of data collection
- set of questions geared toward collecting info about a certain group
- relies on self reporting
- ex. public opinion polls
strengths and weaknesses of surveys
strengths:
-generally inexpensive
-potential clear picture of the phenomena under study
-glimpse into infrequent or private behaviours
weaknesses:
-problems with self reporting
field studies
- observation of everyday life in action
- unobtrusive measures
- participant observation
ethnography
researcher becomes part of the group being studied
strengths and weaknesses of field studies
strengths:
- real world behaviour
- study private and sensitive matters (unibtrusive)
- in depth understandings
weaknesses:
- significant affect of data recording method chosen
- the issue of consent
- time consuming
archival research
- the analysis of data that has already been collected by others
- sources of data archival research data (government, universities, formal organziations)
content analysis
- the systematic study of documents to identify themes and make inferences based on these themes
- ex. prof’s content analysis of legal documents, newspaper documents, and on line discussions
strengths and weaknesses of archival research
strengths:
- inexpensive
- less time consuming
- socio-historical analyses
weaknesses:
- level of control over quality of info
- difficulty creating a reliable and valid study
- inconsistent or missing info in archives
experiments
- high level of control
- composed of two characteristics (independent variables that must be manipulated, and participants that must be assigned randomly)
lab experiment
- researchers have more control
- can control the physical space
field experiement
- less control
- more generalizable (to the real world)
- mitigation of reactivity (become aware of ourselves beinf studied)
strengths and weaknesses of lab experiments
strengths:
- high level of internal validity
- more research control
weaknesses:
- limits to what can be studied
- ethical concerns
- costly
- subject effects (interpret subtle cues as wanting a certain result) and experimenter effects (expects participants to behave in a certain way)
- low external validity
ethics
- protecting and respecting research participants
- ethics approval is required for any research involving human subjects
