Typical 7-Year-Old? In many ways this boy is typical. He likes video games and school, he usually appreciates his parents, he gets himself dressed every morning. This photo shows him using blocks to construct a design to match a picture, one of the ten kinds of challenges that comprise the WISC, a widely used IQ test. His attention to the task is not unusual for children his age, but his actual performance is more like that of an older child. That makes his IQ score significantly above 100.
