Question 1

Which of the following best describes the 'preference technique' used to study infant perception?

Accepted Answer

Researchers measure how long a baby looks at two different pictures to determine preference.

Question 2

What is the primary purpose of the 'visual cliff' experiment devised by Gibson and Walk (1960)?

Accepted Answer

To assess whether infants have developed depth perception.

Question 3

Which type of perceptual cue do infants typically use first to judge depth?

Accepted Answer

Kinetic cues

Question 4

At what age do infants generally begin to use binocular cues for depth perception?

Accepted Answer

About 4 months

Question 5

Which of the following is an example of a monocular cue used in depth perception?

Accepted Answer

Interposition

Question 6

What does 'dishabituation' indicate in infant perception studies?

Accepted Answer

The infant responds to a stimulus as if it were new after becoming familiar with another.

Question 7

Which statement best reflects the nativist view of perceptual development?

Accepted Answer

Most perceptual abilities are inborn.

Question 8

According to research, which auditory ability is present in newborns?

Accepted Answer

Discriminating their mother's voice from another female's voice.

Question 9

Which of the following best describes intermodal perception in infants?

Accepted Answer

The ability to combine information from different sensory modalities.

Question 10

Which of the following is a correct sequence for the development of depth perception cues in infants?

Accepted Answer

Kinetic cues → Binocular cues → Monocular cues

Question 11

A researcher shows a baby a series of pictures with a common pattern until the baby loses interest. Then, a new picture is shown. If the baby looks longer at the new picture, what has occurred?

Accepted Answer

Dishabituation

Question 12

Which of the following statements about infant auditory perception is supported by research?

Accepted Answer

Infants can discriminate some speech sounds better than adults.

Question 13

Which method involves using reinforcement to study infant perception?

Accepted Answer

Operant conditioning

Question 14

Which of the following best illustrates the empiricist view of perceptual development?

Accepted Answer

Perceptual abilities are learned through experience.

Question 15

A 4-month-old infant is able to connect the sound of a rattle with its movement. This is an example of:

Accepted Answer

Intermodal perception

Question 16

Which of the following is true regarding the development of visual attention in infants?

Accepted Answer

Infants' attention shifts from where an object is to what it is by 2 to 3 months.

Question 17

Which of the following best describes the process of synaptic pruning in infant brain development?

Accepted Answer

The elimination of unused synapses after a period of rapid growth.

Question 18

Which real-world scenario best demonstrates the use of the preference technique in infant research?

Accepted Answer

A baby is shown two faces, and the researcher records which face the baby looks at longer.

Question 19

Which of the following is NOT a risk factor for SIDS (Sudden Infant Death Syndrome) according to the study materials?

Accepted Answer

Breastfeeding

Question 20

Which formula best represents the relationship between the number of synapses ($S$) and time ($t$) during the first two years of life, given that synaptic development peaks and then declines due to pruning?

Accepted Answer

$S(t) = a t e^{-b t}$
