Paying less attention as something becomes familiar.

Question 2

Define auditory threshold.

Accepted Answer

The quietest sound a person can hear.

Question 3

Describe the hearing of infants.

Accepted Answer

Good hearing, not as accurate as adults. Best for sounds that have pitches in range of human speech (medium).

Question 4

Hearing impairment can be caused by what?

Accepted Answer

Heredity or disease.

Question 5

When can an infant typically recognize their own name?

Accepted Answer

By 4 months.

Question 6

Define visual acuity. What is the general trajectory of it in infants?

Accepted Answer

The smallest pattern that can be dependably distinguished. Improves rapidly from one month to one year.

Question 7

Until 6 months of age, vision is what?

Accepted Answer

20/240

Question 8

Visually, what do 2-3 week old children prefer?

Accepted Answer

Patterns.

Question 9

At what point is infants’ colour perception like adults’ colour perception?

Accepted Answer

3-4 months.

Question 10

Infants perceive many of the relations between sensory systems (e.g. “multimedia events”). What are three of these ways?

Accepted Answer

Recognize visually an object that they have only touched previously. Detect relations between visual and auditory information. Link body movement to musical rhythm.

Question 11

What four elements are used to perceive objects?

Accepted Answer

Motion, colour, texture, and aligned edges.

Question 12

By 4 months, infants have what four things in terms of perceiving objects?

Accepted Answer

Size, shape, brightness, and colour constancy.

Question 13

What are the five cues for perceiving depth?

Accepted Answer

Kinetic cues: motion used to perceive depth. Visual expansion: as an object moves closer, fills a greater proportion of the retina. Motion parallax: closer objects seem to move faster across the visual field than objects farther away. Retinal disparity: left/right eyes see slightly different versions of the same scene - greater disparity means object is closer. Pictorial cues: arrangement of objects in environment; artists use same cues to convey depth in paintings and drawings.

Question 14

What is the visual cliff? What happens when infants go on it?

Accepted Answer

Glass-covered platform; on one side, pattern appears directly under the glass, but on other, appears several feet below. Young babies can detect a difference between shallow and deep sides; only older, crawling babies are actually afraid of it.

Accepted Answer
