Performance of individual differences in ability development

1, the difference of development level

There are differences in ability. Generally speaking, the performance of ability in the population is normal distribution; Small at both ends and big in the middle. Taking intelligence as an example, the high development of intelligence is called intelligence supernormal or genius; Those whose intelligence development is lower than the average level are called mental retardation or mental retardation; The middle is divided into different levels.

Another situation is called "a late bloomer", which means that the full development of intelligence is manifested at a later age. These people didn't show outstanding abilities when they were young, but they didn't show their talents until middle age. This situation is not uncommon on the stage of scientific and political life. It can be seen that people who have made great achievements are not precocious.

Ability has various components and can be combined in different ways. Due to the different combination of abilities, there are structural differences. For example, some people are good at imagining, some people are good at remembering, and some people are good at thinking. The combination of different abilities is also the difference between people.

Gender differences are not reflected in general intelligence factors, but in special intelligence factors.
