A researcher carries out a conservation-of-number task at a holiday club. Four children sit at the same table. Each child watches one of two matched rows of counters being spread out and then says aloud whether the rows still contain the same number. The other children can hear each answer.
State how many children at a time Piaget tested in his study of conservation of number.
Explain one disadvantage of allowing the children to hear one another's answers.
