Question

the traditional approach to the study of development emphasizes the
change that occurs after adolescence.
extensive changes that occur from birth to adolescence.
developmental changes in utero.
changes that occur across the entire life span.

Explanation:

The traditional approach to studying development historically focused on the significant changes from birth through adolescence (childhood and teen years), as later approaches (like lifespan development) expanded to cover the entire life. The other options are incorrect: post - adolescent change is not the focus of the traditional approach, in - utero changes are part of prenatal development which is not the main focus of the traditional approach, and the entire lifespan is a more modern approach.

Answer:

B. extensive changes that occur from birth to adolescence.
