Adolescence Crash Course Psychology 20 Transcript

If you’re looking for a crash course on adolescence psychology, you’ve come to the right place. Adolescence is a time of significant growth, changes, and struggles for many young individuals. In this article, we’ll explore some of the key concepts and theories related to adolescence psychology.

What is Adolescence?

Adolescence is the transitional period between childhood and adulthood. It is a time when individuals undergo significant physical, social, and emotional changes. The age range for adolescence can vary depending on culture and location, but generally, it starts around the age of 10-12 and ends in the late teens to early 20s.

Physical Changes

During adolescence, physical changes occur as individuals go through puberty. These changes include the development of primary and secondary sexual characteristics such as growth of pubic hair, breast development, and changes in voice for both males and females. Onset of menstruation in females and testicular development in males is also a major physical change during adolescence.

Social Changes

Social changes also occur during adolescence, which involves the development of new relationships outside the family. During this time, adolescents may develop their own identities separate from their parents and try to fit in with peer groups. They may also struggle with issues such as peer pressure, dating, and sexual identity.

Cognitive Changes

Cognitive changes also occur during adolescence. Adolescents develop greater abstract thinking abilities and can reason logically and critically. They also begin to form their own moral and ethical beliefs and values.

Theories of Adolescent Development

There are several theories of adolescent development, including:

Cognitive Developmental Theory

The cognitive developmental theory states that adolescents experience cognitive growth in distinct stages, similar to the overall developmental stages that occur from birth to adulthood. Piaget’s theory emphasized that children transition from the concrete operational stage to the formal operational stage during adolescence.

Psychosocial Development Theory

The psychosocial development theory developed by Erik Erikson describes adolescence as a period of identity formation. Adolescents must develop a sense of identity, or they struggle with an identity crisis leading to role confusion.

Mental Health and Adolescence

Mental health is important during adolescence, especially considering that half of all mental health conditions develop by 14 years of age. Common mental health disorders experienced by adolescents include anxiety disorders, depression, and eating disorders. It is important for parents, educators, and healthcare providers to be aware of the signs and symptoms of mental health issues and provide timely interventions if necessary.


Adolescence is a crucial period in an individual’s life, marking significant physical, social, and cognitive changes. The theories of cognitive and psychosocial development help explain the changes that occur during adolescence. Understanding these changes is important for parents, educators, and healthcare providers to recognize the signs and symptoms of mental health issues and provide timely interventions when necessary.
