Which of the following indicates maturation of the prefrontal cortex by age 6? Select one: a. emotions become more nuanced and responsive b. sleep becomes more irregular c. temper tantrums increase d. uncontrollable laughter and tears are more common

The correct answer is: A) emotions become more nuanced and responsive.

Explanation:

The prefrontal cortex is involved in many aspects of our personality, and its proper development is necessary for life in society since it prevents us from being irrationally impulsive. However, the prefrontal cortex is not fully developed until early adulthood. For this cause, parents must protect their kids from injuries, since they do not have yet the capacity to think before acting in ways that can cause them harm.

Maturation of the prefrontal cortex by age 6 can be expressed in better emotional regulation, a more regular sleep, and a decrease in temper tantrums and uncontrollable laughter and tears.
