Post natal Development
PATTERNS OF GROWTH
Influences on Growth
(Sensory &Perceptual Process)
Babies are born with the ability to communicate their taste preferences to caregivers.
Infant facial expressions indicate they can distinguish among several tastes.
Newborns' rejection of bitter tastes is probably another survival mechanism, since many bitter substances are toxic
De Casper & Fifer (1980): Baby can differentiate mother’s voices from others thru’ baby sucking pattern.
Birnhold & Benacerraf (1983): 28th week baby showed his/her response thru facial expression.
Wertheimer (1961) : Baby able to follow source of sound thru’ the “clicker” test.
Vision is the least developed sense at birth
Newborns cannot focus their eyes very well and their visual acuity fineness of discrimination, is limited
Newborns explore their environment by scanning it for interesting sights & tracking moving objects.
They can’t yet discriminate colors, color vision will improve in a couple of months.
Visual perception is poor at birth but improves to 20/100 by age 6 months
Binocular vision using both eyes to focus
Perception of depth and distance at 4 or 5 months
Brain development helps infants reach adult levels of vision skills:
Langlois & friends (1990): Babies are more attracted to attractive and beautiful human faces.
Fantz (1993): Babies prefer to look at pictures of human.
Aslin (1987): 4 days old babies can differentiate between green and red.
Babies prefer blue and red as compared to other colors.
Gibson & Walk (1960): Visual cliff experiment. 6 mth babies has already develop in-dept perception in visual.
By 1 month, can integrate sight and touch
By 4 months, can integrate sight and sound
4- and 7-month-olds can match facial appearance (boy or man) with sound of voice
