• See page 35…

LONGITUDINAL METHOD

Longitudinal Method

• Researchers select a group of participants and then observe those participants over a period of time.

• (could be over years or decades)• Extremely time consuming• Observations may occur once or twice a year.

CROSS-SECTIONAL

Cross-sectional Method

• Researchers select a sample that includes people of different ages. They then compare the behavior of the participants in the different age groups.

• (instead of following a set of individuals over a number of years).

• Less reliable than longitudinal…why?

• Also called field study• Observing people or animals in their natural

habitats.• Psychologists try not to interfere with the

organisms they are studying.
