Play that involves the use of actions or objects to represent real life or imagined actions, objects, or characters
To engage on pretend play, one must understand mental states (e.g.: the child understands that the mom Is
pretending that she’s using the banana as telephone)
Sensorimotor play: child’s play involving object manipulation as a means for the practice and mastery of actions
Fusiform face area: the area of the brain that is dedicated to face perception
Inversion effect: the disruption in face processing that is observed when face is inverted (i.e., if pictures are
inverted, people are slower to choose)
Holistic processing: the integration of the whole in contrast to its parts (i.e. it is hard for people to see that the
top part of the face is identical when the bottom halves are different because we automatically process the face
as a whole, not by parts)
The early development of face perception:
o Babies would prefer looking at faces than rumbled face parts
o Babies orient to faces at birth and at 2 months but not at 1 month
o U shape curve: Infants show competence, then in a later stage fail to show it, and on the later stage
are able to show it again
Perceptual narrowing:
o A developmental process in which perceptual mechanisms become more specialized such that infants
lose the ability to discriminate between categories that are irrelevant.
o Human 6 months olds were good discriminating both monkey faces and human faces
o 9 month olds are not anymore good at monkey faces but still good at human faces
Young infants expect that people can do things but objects cannot (i.e. an infant is unimpressed if a person
moves but is impressed if an object moves alone)
Also surprised if another ball knocked another ball to a doll but not impressed if a person does it
Infants as young as 3 months old can distinguish animate from inanimate objects based on the objects
movements (i.e. infants spent more time looking at the ball chasing each other than the ball moving
independently at the age of 3 mo;, showing perception of animate motion.
12 months olds saw the yellow triangle helping the red ball up the hill and the blue square hindering the ball
from getting up the hill, he would be surprised if the red ball later approached the blue square rather than the
yellow triangle. Children expect rational behaviours from intentional objects
Intentionality Perception
o Young children have an understanding on other people’s intention
o The child will complete the task though the task is never modeled
o Infants were shown seires of movies with either pause or non-pause; infants dishabituated to the
movie with the pause at the middle but not at the movie where in the pause appears after the
completion of the act.
Difficulty having the theory of mind
Deficits imitation, false belief task, face recognition, and joint attention
