Briefly explain the rouge test and what researchers were measuring when they gave this test to toddlers. What were the findings?
What will be an ideal response?
Answer: Researchers secretly put a red dot on the noses of toddlers of various ages and then placed them in front of a mirror to see if they would touch the dot, noticing that this was not usually there. It was a measure of self-recognition. Younger toddlers (under 18 months) seemed interested in the reflection, because they reached out as though it was someone else, but they did not rub their nose. By 18 months, most toddlers rubbed their noses, showing that they realized that their appearance had changed. This is also the time when toddlers use personal pronouns in their speech.
