Procedure
A cross-sectional study of children. Two rows of parallel counter. Children asked if they were the same. Researcher then stretched one row and asked again.

Criticism 1

Criticism 2
It didn't have much meaning to young children. When a naughty toy was used to move the counters 60% of the children in pre-operational stage passed the conservation of number test. The test had been made child friendly and it contradicted Piagets'

Criticism 3
Small sample. Unable to generalize findings. Especially as part of Piagets' theory states that development is universal. How can he be sure?
