2/3 Review question: Teens born preterm catch up by school entrance True Topic 4 - Infancy  Growth in infancy is faster than any other time of the lifespan o Weight triples by the end of the first year o Height doubles as well  Fat is critical for this growth  Produces enzymes and proteins critical for growth  An adaptive feature for survival Proimodistal Limb growth is greater than abnormal principle growth Cephalocaudal Head and brain growth Brain growth and nervous system development  Primitive reflexes emerge o At birth, they are controlled by lesser-sophisticated parts of the brain  Ex: curling toes, feeling pain, walking reflexes  Disappears by 6/8 months of age  If not gone, intervention is likely needed as it is a cue for unknown potential disabilities  Adaptive reflexes o Reflexes for survival that emerge in due time  Ex: sucking, eyes dilating  Develops from a voluntary process of need - leads to evolution  Brain o At birth, is about 1/4th the size of the adult brain  At two years old, is 70% of full size  Exuberance - growth/birth of synapsis; dendrite connections established  Each dendrite connection is established from any given interaction  Myelination  Myelin sheaths cover neurons to increase speed\  Pruning  Allows increased efficiency of brain  This is done through removing 299 of 300 copies of connections made for any one given connection -> it reinforces the one while removing what is unnecessary  Synaptogenesis  Creation of synapsis  Occurs every time you experience a novel stimulation  Leads to recognition of things like feeding and security, which is triggered from interactions with the mother  Both pruning and synaptogenesis continue throughout life  This is called Plasticity o Environmental impacts (such as neglect or abuse) can have permanent effects on the brain  Plasticity is an adaptive tool in order to overcome damage Brain lobes Frontal Higher processing, decision making; last lobe to fully develop Parietal Processes body sensations Occipita Visual information l Tempora Auditory information, includes language l Sleep  Neonates sleep 16-17 hrs a day  At 3-4 months, they sleep 6/7 hours at night o At this age, parents don’t have to regulate their sleep schedule - the infants will establish it on their own  At 6 months, cultural patterns impact sleep o Aka, will sleep according to the household Crying  Main method of communication  Cries differ per needs o Biologically similar, despite this, across the world  Crying rates increase until about 6 weeks old o Levels off after that  Highly advised to respond promptly to all crying at three months or younger! o canNOT spoil an infant in this way Motor Skills  Gross motor skills o Large movements - aka, running, jumping  Fine motor skills o Minuet movements - aka, harder to develop, like grasping Ossification  Growth and strengthening of bones o At birth, you have all the muscles you will ever have in your life  What changes is the build and connections 2/11 Personality and Temperament in infancy predicts later development  Temperament mixes with environment to produce personality Intermodal Combine two senses to come to a learned perception conclusion Health and wellness  Vaccination use is based on decisions as well as access Nutrition  High fat diet required  May introduce solid food at six months old  Breastmilk is 100% best thing o Provides antibodies the infant requires  This is largely due to the fact that, at birth, the infant has no immune system o Colostrum -> first variation of milk  It can take 3-5 days before the milk actually develops within the mother  Immunity o For vaccinations, you inject small parts of viruses (dead) into the body to learn to defeat it o Illness in first two years is difficult to work with - there are, as such, a lot of vaccinations over the first two years  Infant mortality o SIDS  Between two and four months old  Most vulnerable to it. At this age point  Still no clear cause but risk factors are present  To prevent Sudden Infant Death Syndrome, always put child to sleep on their back  "BACK to sleep" campaign advocates this  If a child can move by themselves, they should be safe from SIDS  Correlating factors  Premature ‘ infants  Too warm of a room  Smoke in the house  Swaddling (prevents)  Hypothesis; brain cannot detect elevated CO2 levels, thus cannot react to it Cognitive development Piaget Key terms Maturation Driving force behind development Schemes Cognitive structures for processing, organizing, and information interpretation Assimilation To fit an existing scheme Accommodat Reshape scheme to fit to new information ion  Four Piaget stages o Sensorimotor o Preoperational o Concrete operation o Formal operation
