Human Growth and Development / Unit 4 HGD 0479 short lesson, about 20 seconds
Social Referencing on the Cliff
Captions available
The idea
In a visual-cliff study of social referencing, mothers at the far side posed different expressions as their infants crawled toward the apparent drop.
In practice
No infant crossing when the mother looked afraid, and about three-quarters crossing when she looked joyful.
Where people slip
Infants use a caregiver's face to decide what an ambiguous situation means, around their first birthday.
