Liam wanted to investigate young children's toy preferences in a natural environment. He placed wooden building blocks and interlocking plastic bricks in the free-play corner of a nursery. Liam sat behind a one-way mirror and observed which toy type the children chose to play with first.

| Gender of child | Wooden building blocks | Interlocking plastic bricks |
|---|---|---|
| Boys | 7 | 3 |
| Girls | 2 | 6 |
