Methods for Studying Child Development Flashcards
Correlations
- relationship –> variables depend on each other
- focus on individual differences or variability
causality
correlation ≠ causation
Other variables (3rd variable problem)
cause both the variables
reverse causality
the reason the mom becomes restrictive is because the child is not compliant
Experiemental Design
control
manipulation
random assignment (randomization)
Naturalistic context
experimenter attempts to observe natural behavior with minimal interference
structured context
- experiementer controls experience of participants
- task can be so structured that only a few responses are possible
advantages of naturalistic
- high external validity
- good for social behavior
disadvantages of naturalistic
- low internal validity (no controls)
- rare events don’t occur
advantages of structured
- high internal validity (standards+ control)
- force rare events
disadvantages of structured
- low external validity
- response biases
cross-sectional design
- different children for each group
- typical patterns or average change
- motor milestones
longitudinal design
- prediction
- same children over time
- stability of individual differences, or prediction
- correlations
microgenetic design
- microscopic
- developmental transition under a microscope
- examining change as it happens and characterizing that change
- same children, studied frequently, during transition
ex) piaget’s conservation task
internal validity
how well a study’s results reflect the true cause-effect relationships within the study
