智商 (zhì shāng): IQ (สติปัญญา)

Although this child is young, his IQ is very high; at five years old, he can easily solve elementary school math problems.

Scientists use a series of tests to measure children's IQ in order to study their cognitive development.

Some parents place too much emphasis on their child's IQ score, but neglect the development of emotional intelligence and social skills.

Doctors used an IQ test to assess his cognitive abilities because he had memory problems after a car accident.

Research shows that IQ is not the only factor determining success; effort and opportunity are equally important.
