Part 2
Is breastfeeding best?
-offers all nutrients the infant needs
-more easily digested than alternative
-provides some immunity to a variety of disease
-may enhance cognitive development
-Mother: !
- may have lower rates of ovarian + breast cancer prior to menopause!
- hormones produced may help to support recovery of uterus following birth
Malnutrition
-Condition of having an improper amount and balance of nutrients, produces several
results none good
-Stunting measured to estimate how children may suffer undernutrition
Crying
-First form of communication
-As brain develops crying rates reduce
Sleeping
Developmental Changes in Sleep
Self-soothing > from 6 months infants put themselves back to sleep
Visual Perception
-Newborns don’t start life with good visual activity
-Similar to being short-sighted
-Vision in early infancy is much worse than in adulthood
-Cant see little things
-Poor colour discrimination
-Percieve objects at distance of approx. 6 m about as clearly as adults do at 183 m-
Physiological constraints
-poor control of eye muscles
-fovea is immature
-Visual abilities grow rapidly
-By 6 months the average infants vision is already 20/20
-Binocular vision
-Depth perception
Infant Visual Preferences
-Preferences are present from birth
-Genetically pre programmed to prefer some kinds of stimuli
-Infants prefer to look at patterned stimuli than simple stimuli
-Faces are special!
- infants prefer human faces!
- their mother’s face!
- can judge different species
Document Summary
Provides some immunity to a variety of disease. May have lower rates of ovarian + breast cancer prior to menopause. Hormones produced may help to support recovery of uterus following birth. Condition of having an improper amount and balance of nutrients, produces several results none good. Stunting measured to estimate how children may suffer undernutrition. Self-soothing > from 6 months infants put themselves back to sleep. Newborns don"t start life with good visual activity. Vision in early infancy is much worse than in adulthood. 6 m about as clearly as adults do at 183 m- By 6 months the average infants vision is already 20/20. Genetically pre programmed to prefer some kinds of stimuli. Infants prefer to look at patterned stimuli than simple stimuli. Crawling - moving around in the environment. Represent the average performance of a large sample of children of a given age. Emphasis on child"s own cognitive state (motivation) in advancing aspects of motor development.
