2.2.3. Cardinality knower task

The Give a Number task (GiveN; Wynn, 1990, Wynn, 1992) was administered to assess children’s number word knowledge. In this task, children were presented with a toy dinosaur and a bowl of 15 small apple erasers and asked: “Can you give Dani the Dino n apples?” After each trial, the experimenter asked the participant to confirm their response by asking: “Is that n?” If participants gave Dani the correct number of apples, the experimenter then asked them to give Dani n + 1 apples. If participants gave Dani the incorrect number of apples, they were asked to give Dani n-1 apples. The highest number word a child knew was defined as the highest correct number of apples a child could give on two out of three trials. Children who reliably gave Dani six apples were referred to as cardinal principle knowers (CP-knowers). Children older than 7 years of age did not complete the GiveN task.
