Final answer:
The characteristic that is not typical of middle adolescence is the myth that teenagers can eat anything without gaining weight. Middle adolescence is marked by physical changes, the development of moral and ethical values, increased independence, and potential engagement in risky behaviors.
Step-by-step explanation:
Among the various characteristics of youths during middle adolescence, one that is not typically associated with this developmental stage is the concept that teenagers can eat anything without gaining weight due to rapid growth. This is a myth and not a characteristic of middle adolescent behavior or development. During middle adolescence, characteristics include:
- Physical changes due to puberty, which can be a source of pride or embarrassment.
- Development of a system of moral and ethical values.
- Increased independence from parents.
- Potential engagement in risky behaviors like early sexual activity or substance use.
- Emerging ability to think abstractly.
However, the generalization that teens can consume any amount of food without weight gain is not substantiated by scientific evidence and is considered a myth.
