3. Seeing
4. Integrating sensory information

Question 2

What is Sensation

Answer 2

Raw input

Question 3

Oral exploration dominates for the first few months.
4 months of age, manual exploration gradually takes precedence over oral exploration.

Question 7

If pain is not managed, it changes how children’s nervous system will respond to pain in the future.
Pain management: sucrose or kangaroo care

Question 8

Visual Acuity

Answer 8

At birth, visual acuity is around one-
thirtieth of adult level.

Question 9

Auditory threshold

Answer 9

the quietest sound a person can hear.
Infants can hear, though not quite as well as adults (get there by the age of 5-6 years)
Infants’ hearing is best for sounds that have pitches in the range of human speech.
Babies recognize the sound of their name by 4.5 months.
Newborns turn toward sounds (=auditory localization).
Infants are also sensitive to music.

Question 10

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