❗ Unit and Larger Context
Not just questions about what babies/children can but, but also how these abilities/behaviors change over time
Interested in:
- Change over age?
- Older children differnces with younger children?
Answering such questions requires studies
Longitudinal design - testing the same children over time
- Tracking the same child’s development at 3 vs 6 months.
Pros: - See change over time
- See continuity and stability of traits and behaviors
Cons: - Time consuming
- Some people don’t come back (need more participants than you really need)
- It is possible that participating in the same study multiple times is a confound
Cross-sectional Design - Different children tested at each age
- One group of infants at 3 months, another at 6
Pros: - Can measure age-related differences
- More efficient than longitudinal designs
- Don’t have to wait for participants to age, don’t have to worry about dropout
- Most experiments are cross-sectional
Cons:
- Can’t really know if group differences are developmental differences
- Can only speak in generalities, nothing about the specific groups we are observing.
- For example, differences could be due to the cohort effect, or the result of the groups being born into different generations (or cohorts)
- Can’t study continuity or stability
Most studies are most interested in age related differences, not the cons we mentioned to cross sectional designs, so those are far and away the most popular
Microgenetic Design
- Special case of longitudinal design
- Patients seen frequently over a short period of time
Pros: - Can observe in-the-moment developmental changes
- Important for uncovering how development happens
Cons: - Doesn’t help understanding development over longer time periods
Age Held Constant Design
By comparing infants who are the same age but differ in the ability to sit we can study the affect of sitting on development
Pros:
- Can examine the effect of factors other than age on development
- Can’t examine age-related changes or differences
