What is pre-adapted?
infants are born with the ability to form social relationships and understand their environments
controls reflexes
Brainstem. Completely functional at birth
motor control
Cerebellum. Still developing at birth.
involved in memory formation
Hippocampus
Myelination
formation of nerve fibers that helps speed nerve impulses
baby grasps with a tight fist; goes away at 3-4 months
Palmar grasp
fencing position laying on back; goes away at 4 months
Tonic neck
put pressure on both palms, they turn head straight and close eyes. Used to get their attention

Rooting reflex
Habituation
automatic decrease in attention that occurs when the same stimulus is presented repeatedly
Orienting response
automatic behavioral and physiological response to the habituated stimulus
Dishabituation
increased attention to new stimulus after habituation to a previous stimulus
Associative learning
certain stimuli or events go together
Classical conditioning
something benign is combined with something stimulating so that we respond to benign object with every stimulation
Operant conditioning
behavior increases or decreases because of consequences
deliberate actions producing large movements, like arms and legs
Gross motor skills
small body movements, especially of hands and fingers
Fine motor skills
early spontaneous arm movements, only sometimes responding to an object; 1-4 months
Pre-reaching

What is retinal disparity?
when eyes are set apart from each other and receive different images
When newborns react reflexively with the whole body
Differentiation
When does pursuit eye-movement begin?
2 months
