
Cross-sectional research: A research method that
compares people of different ages at the same point in
time.
A cohort: is a group of people who grow up at similar
times, in similar places, and in similar conditions.
Longitudinal- research

Longitudinal- research: A research method that
investigates behavior as participants age.
Sequential-research

Sequential-research: A research method that combines
cross-sectional and longitudinal research by considering
a number of different age groups and examining them at
several points in time.
Conclusion

Developmental psychologists are interested in the
effects of both nature and nurture on development.
Environment
and
heredity
both
influence
development, with genetic potentials generally
establishing limits on environmental influences.
