Could someone explain me the difference between maturity and mental age since both concepts seens similar to me. There are many children who are more intelligent than many adults and have better cognition as well. It makes more sense that children should be smarter than adults since children have more neurons and connections. Mental disability or retardation is when a person have cognitive and life skills that are significantly lower than the average person but it has several levels that relate it with mental age. For me intelligence have nothing to do with maturity or mental age. A person can be very smart and be childish and immature and vice versa.
So why is mental retardation linked to mental age up to 12 years old? It`s like saying that children aren`t intelligent and that is not true.
So the key question of the topic is why mental age linked to maturity and intelligence since they are very different things? Is it scored based on what people expect about the behavior and way to think of a person of a certain age? For exemple WJFOX is 40 years old now. If he have behaviors that is mostly common for people who are 15-18 years old is he somewhat mental retarded just because of that? I don`t think so. I think that everyone is different and unique in their own way having their own personality.
Another thing: Why the mental age needed for an adult have mental retardation is up to 12 years old?
