Question 1

It extends from
birth to one month

Answer 1

Neonatal Period.

Question 2

newborn is about 20
inches long and weighs about 7 ½
pounds.

Answer 2

Neonate

Question 3

is an involuntary and automatic
response to a stimulus, as when the eye automatically blinks in response to a puff of air.

Answer 3

Reflex

Question 4

have clear adaptive value. (e.g. breathing reflex, the eye-blinkreflex, sucking, swallowing reflexes and rooting reflex)

Answer 4

Survival reflexes

Question 5

involuntary motions
that aid in the development of certain skills in babies not nearly as useful as survival reflexes
(e.g. Babinski reflex, Swimming reflex, grasping reflex, stepping reflex)

Answer 5

Primitive reflexes

Question 6

INFANT STATES OF AROUSAL

“Baby is still, with eyes closed and unmoving. Breathing is slow and regular.”

Answer 6

Regular sleep

Question 7

INFANTS STATES OF AROUSAL

Baby’s eyes are closed but can be observed to move under the closed eyelids (a phenomenon known as rapid eye movements, or REMs). Baby may jerk or grimace in response to stimulation. Breathing may be irregular.

Answer 7

Irregular Sleep

Question 8

INFANT STATES OF AROUSAL

Baby is falling asleep or waking up. Eyes open and close and have a glazed appearance when open. Breathing is regular but more rapid than in regular sleep.

Answer 8

Drowsiness

Question 9

INFANT STATES OF AROUSAL

Baby’s eyes are wide open and bright, exploring some aspect of the environment. Breathing is even, and the body is relatively inactive.

Answer 9

Alert inactivity

Question 10

INFANT STATES OF AROUSAL

Baby’s eyes are open and breathing is irregular. May become fussy and display various bursts of diffuse motor activity.

Answer 10

Alert activity

Question 11

INFANT STATES OF AROUSAL

Intense crying that may be difficult to stop and is accompanied by high levels of motor activity

Answer 11

Crying

Question 12

As infants develop, they spend less
time sleeping and more time awake,
alert, and attending to their
surroundings.

• By age 2 to 6 weeks, babies sleep
only 14 to 16 hours a day.

Answer 12

Changes in Sleep

Question 13

the unexplained death of a
sleeping infant who suddenly stops
breathing (also called crib death).

Answer 13

Sudden infant death syndrome or
(SIDS)

Question 14

True Or False

Earliest cries is unlearned and
involuntary responses to discomfort
(e.g. Hunger, Pain and Wet Diaper)

Answer 14

True

Question 15

Research Methods for Infant’s sensory and perceptual
experiences

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

a method used to gain information
about infants’ perceptual abilities
by presenting two (or more) stimuli
and observing which stimulus the
infant prefers.

What Method is this?

Answer 15

PREFERENCE METHOD

Question 16

Research Methods for Infant’s sensory and perceptual
experiences

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

a decrease in one’s response to a
stimulus that has become
familiar through repetition.

very useful for assessing their
sensory and perceptual
capabilities.

What Method is this?

Answer 16

HABITUATION METHOD

Question 17

The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.

Answer 17

Sensation

Question 18

The process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events

Answer 18

Perception

Question 19

Research Methods for Infant’s sensory and perceptual experiences

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Determining what infants
can sense or perceive is to
present them with a
stimulus and record their
brain waves.

Answer 19

Method of Evoked Potentials

Question 20

a change
in patterning of the brain
waves which indicates that
an individual detects
(senses) a stimulus.

Answer 20

Evoked Potential

Question 21

Research Methods for Infant’s sensory and perceptual experiences

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

a method of assessing infants’ perceptual capabilities that capitalizes on the ability of infants to make interesting events last by varying the rate at which they suck on a special pacifier.

Answer 21

High-Amplitude Sucking Methods

Question 22

the transformation of stimulus energy into neural impulses.

Answer 22

Transduction
