Oservational techniques Flashcards
naturalistic
watching + recording behaviour in a natural setting, not changed
reseracher doesn’t interfere + just observes behaviour as it happens normally
controlled
behaviour observed under strict conditions e.g lab
EV controlled
control of some variables
artificial environment
observational techniques
way of seeing + listening people without asking them
pro observational techs
- can capture unexpected behaviour
con observational techs
- cant determine cause and effect as variables not observed + not manipulated
- observer bias- using more than 1 observer will reduce this- less objective- less accurate
naturalistic pro
- higher level of ecological validity- behaviour natural as environment is original + realistic- therefore behaviour more representative of everyday activities- generalised to everyday life- reflect real behaviour- high external validity
naturalistic con
- issues w replication + reliability
- lack of control over EV that may influence behavhiour being observed
controlled pro
- EV controlled
- easily replicated- high reliability- as variables highly controlled
controlled con
- low external validity- artifical environment as variables manipulated- high level of control is unnatural- ppts behaviour not natural- cant be generalised- low ecological validity
covert
ppts not aware being studied e.g. two way mirror.
behaviour watched without their consent
undisclosed, without their knowledge
observer not visible and hidden
overt
ppts aware being studied
informed consent given before hand.
observer clearly visible not hidden
covert pro
- high internal validity- ppts bheaviour natural- - no demand characteristics changing behaviour
- less investigator effects- hidden so less direct or indirect behaviour that will impact ppts performance- less demand characterisitcs- wont try to guess aims of study as unaware being observed- natural behaviour- representative - generalisable
covert con
- ethical issues- lack of informed consent- not aware being studied
overt pro
- more ethical- aware being studied- so can gain informed consent- allows right to withdraw- reputation of psych protected
overt con
- investigator effects- bias as they influence ppts- ppts suffer demand characteristics- no natural behaviour- reduces internal validity
