Final answer:
Television affects children's self-esteem through the portrayal of unrealistic body images, stereotypes, and media violence, which influence their self-concept and behavior.
Step-by-step explanation:
One of the ways in which television tends to affect the self-esteem or self-concept of children or adolescents is by portraying unrealistic body images and stereotypes. For example, young people are exposed to images of extremely thin models, which may not only be unattainably perfect but sometimes are digitally altered to appear even thinner. This exposure can contribute to negative body image, low self-esteem, and could potentially lead to eating disorders. Additionally, television shows often contain a gender imbalance and stereotypical portrayal of women and minorities, which can affect how children perceive themselves and others.
Moreover, the frequency of viewing media violence can lead to aggressive behavior and desensitization to violence, impacting a child's psychosocial development. Repeated exposure to certain televised contents can communicate what is seen as normative and desirable, thus influencing the views and behaviors of young audiences.
Overall, television and media heavily contribute to socialization and serve as powerful sources of norms, expectations, and beliefs that can shape self-concept and behavior in children and adolescents.
