Summary
Adolescent body image and self-concept change with age. Increased brain activity in the inferior parietal lobe during self-evaluation correlates with perceiving oneself as larger, highlighting neural development
Area of Science:
- Developmental Psychology
- Neuroscience
- Body Image Research
Background:
- Adolescence involves significant changes in self-concept and physical body.
- Body image development is influenced by evolving self-perception and physical changes.
- Understanding the interplay between self-concept, body image, and neural correlates is crucial.
Purpose of the Study:
- To investigate the developmental trajectory of body image during adolescence.
- To examine the relationship between self-concept development and body image.
- To identify the neural correlates associated with body image perception in adolescents.
Main Methods:
- Longitudinal study of adolescents (aged 11-24) over three years.
- Assessment of body image using figure rating scales and body dissatisfaction questionnaires.
- fMRI task to evaluate neural activity during physical appearance self-evaluation.
Main Results:
- Body estimation and body dissatisfaction increased with age throughout adolescence.
- Higher activation in the inferior parietal lobe (IPL) during physical self-evaluation was linked to lower body estimation.
- IPL activity demonstrated continued development, suggesting interaction with body perception.
Conclusions:
- Body image perception and dissatisfaction evolve during adolescence.
- Neural development, particularly in the IPL, interacts with body perception.
- Body image is shaped by a complex interplay of affective, perceptual, and biological factors.

Self-concept is the cognitive and emotional understanding individuals hold about their identity. It evolves through various developmental stages, beginning in infancy and maturing as children grow. This concept influences how individuals perceive their abilities, interact with others, and manage challenges throughout life.
Infancy and Emerging Recognition
During infancy, self-concept is virtually nonexistent. Babies do not distinguish themselves as separate entities and often mistake their...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

01:17Erikson's Theory on Socioemotional Development during Adolescence
92
Erik Erikson's fifth stage of psychosocial development, "identity versus role confusion," is crucial during adolescence (ages 12 to 18). In this stage, adolescents face the developmental task of forging a distinct personal identity, a process influenced by social, psychological, and biological changes typical of this period. Adolescents naturally explore different roles, behaviors, and ideologies as they navigate complex questions of self-concept, asking, "Who am I?" and...

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

01:18Cognitive Development During Adolescence
52
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...
