Caregiver infant iteractions-EVALUATION Flashcards
what is a strength of filming obseravtions?
filming in a lab means that it is a CONTROLLED observation.
this reduces EXTRANEOUS variables from becoming confounding and affecting the validity of the study.
Recording also allows researcher to GO BACK and replay, ensuring no behaviour has been missed, raising validity,
what is a strength of the observation being covert?
the observation is COVERT meaning the babies will NOT CHANGE their behaviour due to the presence of the researcher.
(High internal validity and reliability)
What is one weakness of observing babies?
they are HARD to observe and interpret their behaviours. e.g. a smile may be wind.
babies lack co-ordination, SUBTLE movements may not be noticed, and whether they have a SPECIAL meaning behind them or not.
THEREFORE,
this affects the internal validity of the study as we may not be measuring caregiver -infant interaction as we believed.
