Piaget Underestimated Infants
Captions available
The idea
Later research found that Piaget underestimated infants: tasks without reaching show object permanence around four months and deferred imitation as early as six months.
In practice
A four-month-old staring longer when a hidden object seems to vanish without cause.
Where people slip
The misconception is that Piaget's ages are fixed limits. His tasks demanded skills, such as reaching, that infants lacked.
