Chapter 5: Perceptual and Motor Development

Question 1

Sensory and Perceptual Processing

Answer 1

means by which people receive, select

Question 2

Motor Skills

Answer 2

Coordinated movements of muscles and limbs

Question 3

Habituation

Answer 3

When a baby pays less attention to a stimulus being repeatedly presented because it has become used to it

Question 4

Use of Habituation

Answer 4

Used to see if babies can distinguish different stimuli

Question 5

What senses do babies primarily use during the first few months

Answer 5

Smell, taste, and touch

Question 6

Uses of smell, taste, and touch for infants

Answer 6

Can identify important objects such as parents and can soothe pain by being comforted

Question 7

Hearing in Infants

Answer 7

Infants can hear, but not as well as adults

Hear pitches in human vocal range best

Question 8

Auditory Threshold

Answer 8

The quietest sound a person can hear

Question 9

Auditory localization

Answer 9

Use sounds to judge distance and location of objects

Question 10

Visual Acuity

Answer 10

The ability to distinguish small patterns dependably

Question 11

Visual Cones

Answer 11

Found on retina and allows people to see colours along visual spectrum

Question 12

When are visual cones fully developed in infants?

Answer 12

Around 3-4 months old

Question 13

Visual Acuity in Infants

Answer 13

Can see at 6 meters what an adult can see at 60-120 meters

Question 14

Amodal

Answer 14

Certain information can be processed using a variety of senses

i.e. how fast a pianist is playing using visual cues and auditory cues

Question 15

Intersensory Redundancy Theory

Answer 15

Infants perceptual system attuned to amodal info

Question 16

Perceiving Objects

Answer 16

our perceptual processes determine certain features go together to form objects

Question 17

How do babies identify objects

Answer 17

By using motion, colour, texture, and aligned edges at the age of 4 months

Question 18

Shape Constancy

Answer 18

Even though an object appears to change shape we realize that it is still the same shape as before

Question 19

Kinetic Cues

Answer 19

Motion used to estimate depth

Question 20

Visual Expansinon

Answer 20

As object gets closer it takes up more of our visual field

Question 21

Motion Parallax

Answer 21

Nearby objects move faster along visual field

Question 22

Retinal Disparity

Answer 22

A visual setting looks slightly different to each individual eye. As an object gets closer the disparity grows

Infants are capable of using this at 7 months old

Question 23

Pictorial Cues

Answer 23

Cues that artists use to convey depth in paintings

Question 24

Perceiving Faces

Answer 24

Infants like to look at faces and by 3 months look at features of faces

Question 25

Attention

Answer 25

Process by which we select info that will be processed further

Question 26

Orienting Response

Answer 26

Person startles, fixes eyes on stimulus, and shows changes in heart rate and brain wave patterns
