Visual tracking
how an infant follows an object
preferential looking
a method for studying visual attention in infants that involves showing infants two patterns of two objects at the same time to see if the infants have a preference for one over the other
Habituation
show how long the baby looks at a certain object
become less interested in the same toy and more interested when there is a new one
Simplest form of learning
Infant has to see the stimulus, track it and form a memory of it
manual exploration
infants touch objects, don’t understand how pictures differ from the real thing
manual search
Piaget used this method
established object permanence
Before 12 months, an infant’s representation of an object s fragile
