Late adolescence is the age range of 17-19 years. At this stage, individuals are legally adults, and their thinking and intellect are fully developed. Their thinking becomes more flexible, their identity becomes clearer, and they begin to seek the career they want or aspire to have in the future. They become more mature, no longer self-centered, and are interested in how people around them think about them, what expectations or views others have of them. They can better adapt to external thoughts, needs, and rules. Initially, they may follow their own thoughts and beliefs, but they will develop their thinking and adjust to fit in better with others.
What are the emotions of late adolescents like?
Their emotions are stable, less impulsive, and calmer. Socially, they interact more with their family while maintaining good relationships with friends. They help their family and friends more and manage themselves better.
How are the thinking and decision-making of late adolescents?
Their thinking becomes more diverse and adaptable. Their decision-making considers reasons and logic more. At this age, they no longer have problems with physical changes.
Personality development in late adolescents
Their personality becomes clearer. Personality starts forming from early childhood, such as knowing their gender and imitating parents. When entering adolescence, they begin to imitate friends or admired individuals and explore their roles more clearly to grow into adults. Their personality gradually becomes distinct, such as being approachable, peace-loving, or preferring to work independently. They start to understand their strengths and weaknesses, what they are sensitive to, likes and dislikes, and can express to others what kind of person they are.
Symptoms or behaviors for which parents should consult a doctor
During this period of adjustment in physical, mental, emotional, and cognitive aspects, if problems arise in any stage—such as emotional issues, difficulty adapting, or thinking patterns that hinder proper development, for example, inability to study, inability to get along with friends or family—parents should take the child to see a doctor for treatment planning and further advice.
