Working with colleague Diane Dumas, Dr. Epstein has developed a unique and comprehensive test—the Epstein-Dumas Test of Adultness (EDTA)—that measures 14 different competencies that appear to define adult functioning in modern society. Based on scores obtained from adults and teens, Drs. Epstein and Dumas recently concluded that American teens are, on the average, just as competent as American adults—in other words, that we are probably underestimating the abilities of our teens. Their research also shows a link between "infantilization"—the extent to which teens are treated like children—and behavioral problems in teens.

Research has taught us that the human brain doesn't fully mature until a person is in their late twenties. Up until just 8 to 10 years ago the brain was thought to be fully developed by the age of 16. We have also learned that the way an immature brain processes information is different from the way a mature brain processes the same information. The immature brain is more emotional than intellectual based. Decisions are less rational and more impulsive. For this reason, a teenager's ability to assess risk is impaired.

But there is one crucial part of the brain that is not finished developing until about age 25, and that is the prefrontal cortex, or PFC for short. It is also sometimes referred to as the executive brain because that is where the executive decisions are made. It is where you assess risk.

Jobs and Gates dropped out of college and created Apple & Microsoft, but they were too young to
effectively manage the companies they created. Maybe their inability to assess risk worked to their advantage.
I wonder if executive capability somehow impairs creative energy.

Found this:

Those of us in the biz don’t typically think of intelligence in terms of left and right brain. Usually, we speak in terms of verbal and performance abilities.

Verbal IQ includes things like short term memory, language comprehension, and sequential information processing. Performance IQ includes spatial reasoning, non-verbal logic, visual-motor skills, and so on.

This division is somewhat arbitrary, but there are advantages to it. For one thing, discrepancies in verbal and performance abilities help diagnose problems such as head injury, developmental disabilities, dementia, and stroke. The verbal/performance division also helps us understand how the mind ages. I hate to tell ya, Jane, but our brains are slowly falling apart.

As we age, performance IQ tends to decline fairly quickly. Processing speed is one of the first things to go. It tends to peak in the early twenties, after which it begins the long, downhill slide. Nonverbal reasoning and visual-motor coordination are not far behind. Working memory, which allows us to do things like remember shopping lists, typically begins to decline during the thirties or forties.

Verbal abilities, on the other hand, tend to stay pretty strong throughout this lifespan. Verbal reasoning, fluency, and language ability show gains through the thirties and forties, as do arithmetic skills. Even though they later decline, they tend to stay pretty strong until we reach the finish line. Our long-term recall of concrete information (Who was the first president? What was the name of that sexy teacher in third grade?) also remains fairly strong. That’s assuming you’re lucky enough to avoid dementias such as Alzheimer’s.
Don't let this talk of mental decline and plentiful lawyers get you down. There is good news.

As we age, verbal abilities tend to outlast performance. That’s why there are no 60-year-old fighter pilots, while there are plenty of skilled, 60-year-old lawyers.
