Baillargeon and colleagues ( 1987; 1991 ) have conducted several classic studies in which young,
premobile infants are shown "impossible" events, such as the appearance of a car passing
through a barrier, only to reappear on the other side.
How do these researchers interpret the
results of their work?
A) That an infant's understanding of object permanence is not mastered until six months of
age.
B) The fact that the premobile infant shows "surprise" when the object reappears means that
infants understand object permanence earlier than Piaget once thought.
C) The neural mechanisms responsible for visual searching and reaching-grasping are the
same.
D) Infants will only show "surprise" over reappearance of the object if they are familiar with
it.
