Question 2 · Short answer
Mention any four psychological changes that adolescents go through during this period. [2]
Answer: Adolescents become too conscious about themselves. They start worrying about the growth in various parts of their body. They feel shy and hesitant in sharing their problems with others. They sometimes develop depression because of the dramatic increase in hormone levels.
Other points a student may include: adolescents like to remain with their group of friends or peers most of the time, and try to imitate what others in their peer group do.
