Early Sensory Capacities

Hearing changes that take place during infancy involve

perception of volume, pitch, localization.

Infants show an interest in

________human faces soon after birth and prefer to look at faces rather than other objects.

Visual cliff study

________ was designed to test depth perception and visual expectations.

Hearing begins in

the womb.

In the first two months of postnatal development,

infants don’t perceive obstructed objects as complete, instead perceiving only what is visible.

Use of ‘binocular cues’ by age 3 to 4 months suggests

depth perception even before infants can crawl.

At birth the nerves and muscles and lens of the eye

are still developing.

Visual acuity and color in newborns

improve over time.

Newborns respond to

touch and can feel pain.

Hearing is one of the keys to

language development

Visual acuity varies from

20/240 to 20/640.

Head movement indicates

some vision.

Sensitivity to taste is present

even before birth.

Over the first several months of age, infants begin to prefer

salty tastes.

In terms of hearing, changes that take place during infancy involve

perception of volume, pitch, localization.

Infants also show a preference for

attractive, smiling faces

What kind of objects do infants prefer?

Familiar over unfamiliar objects

In the visual cliff study, did infants crawl over the edge?

Infants did not crawl over the edge.

Newborns can differentiate

odors

In the visual cliff study, it was concluded that

the infant’s perception of affordances let them crawl or not crawl over the cliff
