IQ test results change in response to brain growth, emotional health, education and experiences.
Changes in the grey matter areas of the brain that are related to muscle control, seeing and hearing, memory, emotions, speech, decision making, and self-control are responsible for the rise and fall of IQs in teenagers.
The teen brain undergoes many changes just like the more observable physical changes. It actually kills off parts of itself to stream line performance.
Because the changes occur from the back of the brain to the front, the regulating part is the last to mature resulting in impulsivity. Teenagers rely heavily on the emotional part of the brain, to make decisions…uh oh.
There’s a lot going on in there, no wonder IQ test results change!
