A 15-year-old is investigating a device with two switches, A and B. The device lights up in some switch settings.
| Test | Switch A | Switch B | Device lights up? |
|---|---|---|---|
| 1 | Off | Off | No |
| 2 | On | Off | Yes |
| 3 | On | On | Yes |
After these tests, the teenager chooses to test the device with switch A off and switch B on.
Using Piaget's theory, explain what the teenager's choice of this further test, given the results so far, suggests about their thinking.
