Designs in Child Development Flashcards
What designs are used to study development?
- Longitudinal
- Cross-sectional
- Sequential
- Microgenetic
What is Longitudinal design?
- Follow constancy and change in the domains across individuals over time
- Common patterns and individual differences
Strenghts and problems with longitudinal design?
- Permits study of common patterns and individual differences in development
- Relationships between early and later events and behaviours
-Biased Sampling
- Selective attrition
- Practice and cohort desing
- May become outdated due to changes in theories and methods
Biased sampling
Failure to enlist participants who represent the population of study as a whole
Selective attrition
People may drop out, and those who continue are likely to differe from those who left in important areas
Practice effect
Better at taking tests rather than showing change in development
Cohort effects
Children developing in the same period are influenced by cultural and historical changes
- One cohort may not apply to other cohorts
Studying before coivd, during coivd and after covid
What is cross-sectional studies?
- People of differing ages all studied at the same time
- See age related trends
What are the strengths and problems with cross-sectional design?
- Efficient
- Not plagued by selective attriction, practice effects or theories and method changes in the field
- Cant see development over time
- Cohort effects, unique group
What is sequential design?
- Longitudinal and cross-sectional comparisons
- Revelas cohort effects
- Permits tracking of age.related changes more effectively
- May have same problems as the other designs, but this design helsp identify difficulties
What is microgenetic design?
- Extension/adaption of the longitudinal approach
- Children are presented with novel task, follow their mastery closely over several sessions
What are the strenghts and limitations of microgenetic designs?
- Offers insight into how changes occur
- Cognitive development
- Time-consuming
Alot of data
Participants, several sessions - Familiarization with the task may produce misleading findings
