Research Methods : Observational Techniques Flashcards
what do obsv provide psychologists with
way of seeing what peeps do without asking them
researchers can stuyd in a natural or controlled enviro allowing
flexibility study > complex interaction btwn variables
observation often used within an experiment as what
way of assessing dependent variable
naturalistic observation
obsv happens in place where target behaviour noramlly displayed
in a NO how are aspects of the enviro
aspects fo enviro free to vary
when is it good to do in a NO
study interaction in enviro where it would normally take place where doesn’t make sense a lab setting
what is a controlled observation
obsv used when useful to control variables and aspects of research situation
how did ainsowrth control her stuyd
specifically designed playroom which they recorded data through two way mirror
why did ainsowrth record data through a two way mirror
not to distub the action
in a controlled obsv there is some control over variables including
manipulating variables
to observe effects
reduce confounding/extraneous variables
+VE of NO
High EV
findings can be generalsied to everyday life casue of behaviour studied in eviro where would normally occur
-ves of NO
LACK OF CONTrol over research situation makes replication of investigation diffcult
therfore reduces reliability ?
+
may also be many uncontrolled confoudning/extraneous variables that make it more difficult to judge any pattern of behaviour
reduces internal validty
may also be uncontrolled confounding/extraneous variable making it more difficult to judge any pattern of behaviour
-ve of controlled obsv
cannot be applied to everyday life - low ev
+ve of controlled obvs
confounding/extraneous varibale less of a factor so replication of obsv becomes easier
behaviour may be occasionally recorded without first
getting consent of pt
