All Rights Reserved Sleep Changes • Neonates sleep 16 to 17 hours • At 3 to 4 months sleep 6 to 7 hours at night-Dramatic difference • At 6 months cultural patterns influence sleep patterns – American: 14 hours- ?? – Kipsigis: 12 hours- Always strapped or carried by mom or family. Less active. – Dutch: 16 hours- Value rest and early bedtimes. Copyright © 2017, 2013 Pearson Education, Inc. All Rights Reserved Sudden Infant Death Syndrome • Infants between 2 to 4 months of age have highest risk for Sudden Infant Death Syndrome (SIDS) – Leading cause of death for infants 1 to 12 months in developed countries • No clear cause but there are risk factors – Sleeping on stomach instead of back – Low birth weight and APGAR score – Smoking – Soft bedding • Campaign to reduce SIDS includes a “BACK to Sleep” campaign • Campaign has caused reduction of SIDS worldwide Copyright © 2017, 2013 Pearson Education, Inc.

All Rights Reserved Infant Health: Nutritional Needs (1 of 2) •Infants need a high-fat diet which breast milk provides. •About 6 months may introduce solid foods – Cultural variations in types of food introduced – West – rice cereal – Traditional cultures – mashed, prechewed, pureed Copyright © 2017, 2013 Pearson Education, Inc. All Rights Reserved Infant Health: Nutritional Needs (2 of 2) • Malnutrition during this time can be severe and enduring • Can be caused by inability of mother to breast feed • Marasmus- is a risk for malnourished infants Copyright © 2017, 2013 Pearson Education, Inc. All Rights Reserved Infant Health: Infant Mortality • Most infant mortality takes place during the first month of life • Top sources of infant mortality beyond the first month but within the first year include – Malnutrition – Malaria – Diarrhea . Can be helped with oral rehydration therapy- is a fluid replacement strategy used to prevent or treat dehydration. • Vaccinations have been beneficial Copyright © 2017, 2013 Pearson Education, Inc.

What are some potential causes of the high infant mortality rates in developing countries? Copyright © 2017, 2013 Pearson Education, Inc. All Rights Reserved Cultural Beliefs and Practices to Protect Infants Traditional cultures: • Parents’ awareness of infant’s vulnerabilities influenced parenting practices- Help babies survive. • Developed practices to help infants avoid harm- We find ways to keep them safe. • Current practices may be magical where knowledge is limited- We look to other methods when we don’t have answers. Copyright © 2017, 2013 Pearson Education, Inc. All Rights Reserved Motor and Sensory Development (1 of 5) • Gross motor development includes whole body movements like crawling • Children tend to develop gross motor skills in sequence • Sequence has genetic beginnings with environmental influences- Let them move! Our bodies know what to do and our environment supports that development. • Cultural practices emphasize the role of environment on gross motor skills- Are babies allowed to move? Copyright © 2017, 2013 Pearson Education, Inc.

All Rights Reserved Motor and Sensory Development (4 of 5) • Hearing develops during the last trimester of fetal development • Infants can distinguish sound categories but are limited in encoding all aspects of a situation • May use statistical learning to encode and learn about the world • Vision develops rapidly after birth • Infants prefer complex patterns and faces Copyright © 2017, 2013 Pearson Education, Inc. All Rights Reserved Motor and Sensory Development (5 of 5) • Depth perception is influenced by development of binocular vision at 2 to 3 months of age- The ability to combine the images of each eye into one image. – Important when children become mobile- depth perception • Visual cliff useful in understanding and emotional development Copyright © 2017, 2013 Pearson Education, Inc. All Rights Reserved Intermodal Perception • Intermodal perception – One-month-olds recognize things they put in their mouth to things they haven’t seen before. – Six month-olds match number of sounds to number of sights they have seen – By eight months can match unfamiliar faces with correct voice and gender – Neural correlates of intermodal sensory activity- measurement of brain function. The brain lights up when a baby shows interest. Copyright © 2017, 2013 Pearson Education, Inc. All Rights Reserved Cognitive Development Copyright © 2017, 2013 Pearson Education, Inc. All Rights Reserved The Sensorimotor Stage • Sensorimotor stage can be divided into six substages; the first 4 occur in infancy – Substage 1: Simple reflexes (0-1 month)-Sucking, rooting, grasping. – Substage 2: First habits and primary circular reactions (1-4 months)- purposeful movement and behavior begins i.e sucking on hand. – Substage 3: Secondary circular reactions (4-8 months)- The repeating of those actions with purpose. – Substage 4: Coordination of secondary schemes (8-12 months)- Actions are now intentional. Copyright © 2017, 2013 Pearson Education, Inc. All Rights Reserved The Sensorimotor Stage: Object Permanence • Piaget: Object permanence – objects continue to exist even when not aware of them – Under 4 months – no understanding – 4 to 8 months – some uncertain about existence – 8 to 12 months – developing awareness . Will still make A not B error Copyright © 2017, 2013 Pearson Education, Inc. All Rights Reserved Evaluating Piaget’s Sensorimotor Theory Criticisms include: – Underestimating infants’ ability especially regarding object permanence – Renee Baillargeon and researchers tested infant abilities using the violation of expectations method – Object permanence may reflect memory development – Cultural limitations as well Copyright © 2017, 2013 Pearson Education, Inc.

Decrease in A box is placed to stop the attention. drawbridge from going completely down. Child becomes interested again. Stayed interested as the box was taken off and on. The experiment inferred that babies who cooed and looked interested knew the box was manipulating the drawbridge. Therefore knew it was there. Copyright
