Question

Quizplus · Accepted Answer

Previous research has shown that at about 18 months of age, babies recognize that the image in the mirror is their own image. If the researcher now puts a dot of red rouge on the toddler's nose, there is a classic reaction. The toddler points to her own nose, turns her head away from the mirror, drops her eyes, smiles, and looks embarrassed.
