AP PSYCHOLOGY

Detailed explanation-1: -The frontal lobes, home to key components of the neural circuitry underlying “executive functions” such as planning, working memory, and impulse control, are among the last areas of the brain to mature; they may not be fully developed until halfway through the third decade of life [2].

Detailed explanation-2: -The development and maturation of the prefrontal cortex occurs primarily during adolescence and is fully accomplished at the age of 25 years. The development of the prefrontal cortex is very important for complex behavioral performance, as this region of the brain helps accomplish executive brain functions.

Detailed explanation-3: -Though the brain may be done growing in size, it does not finish developing and maturing until the mid-to late 20s. The front part of the brain, called the prefrontal cortex, is one of the last brain regions to mature. This area is responsible for skills like planning, prioritizing, and controlling impulses.

Detailed explanation-4: -According to recent findings, the human brain does not reach full maturity until at least the mid-20s. (See J. Giedd in References.) The specific changes that follow young adulthood are not yet well studied, but it is known that they involve increased myelination and continued adding and pruning of neurons.

Detailed explanation-5: -Brain Maturity Extends Well Beyond Teen Years Under most laws, young people are recognized as adults at age 18. But emerging science about brain development suggests that most people don’t reach full maturity until the age 25.
