Quiz 2 Study Guide Flashcards
(74 cards)
Brain Percentage from birth to age 2
Birth=25% and age two=70% brain weight
2 Year brain weight/height/weight
75% brain weight- ½ adult height- ¼ adult weight
Transient Exuberance and amount of neurons
5x more dendrites (35% skull growth in first year)
100-200 billion neurons
Synaptic density
Neurons decrease but the amount of synapses increases (2 Million per second w/ total of 100 trillion at age 2)
Synaptic pruning
Axons that are not used are removed and remaining 2/3 of axons become more effective (Use it or lose it)
Growth of frontal lobes and cerebral cortex
Frontal lobes develop faster then rest. Cerebral cortex splits into two sides.
Toddlers signs of brain development
enjoy routines, doing chores, ect
Early childhood brain development
axons continue to decrease, right and left brain tendencies appear. Motor development increases along with attention. Hypocampus is developed and able to have long term memory
Affordances and examples
are educational rich experiences that promote development such as toys-balls, pots, bottles, ect. Has more chances for play.
Know about axons-dendrites
Axons send and dendrites receive
Infancy Gross motor development
3 Months roll over
6 months Can sit up and
9-15 months for first steps and could become walking
Infancy Fine motor development
3-6 months to reach and grabbing and picking up items and transferring objects (pincer grasp)
Toddler Gross motor development
9-17 months- stand alone and walk without support (improved balance)
11-21 months- stand on one leg and climb onto chairs/bed/ect (11 months is usual time to walk)
13-22 months- walk backward and run
16-30 months- jump in place and walk on tiptoes
22-36 months- walk up and down stairs
Toddler fine motor development
7-16 months- hold writing instrument and coordinate hands (multi task)
10-21 months- build tower of two blocks and scribble vigorously
12-18 months- feed self with spoon
15-23 months- build tower of 3-4 blocks
20-28 months- draw straight line on paper
24-32 months- brush teeth
26-34 months- tower of 8-10 blocks
29-37 months- copy circle
Early Childhood motor skills
Running jumping
Boys are good with strength and girls are good at balance
Fine
Can dress themselves and cut food up, brush teeth, scissors (allows indepence and responsibility and show preference between right and left hand)
Infants
Need fat and nutrition (breast milk)
4-6 months solid food is introduced such as soft rice food
1 ½ to chew and swallow
Toddlers eating habits
Winged and eat similar to adults by age 2
High choloric needs
Important to learn how to eat healthy- vegetables (be an example)
Early childhood eating habits
Eat and enjoy whatever is given by care giver
Food preference change a lot
Circular reactions
one action and receives a responce from outside world
Primary circular action
intentional reflexes
Secondary circular actions
(4-8 months)- repetition of actions that happened by accident to make an interesting event last
Tertiary circular reactions
(18 months)- intentional doing actions to discover affects
Habituation
When a stimulus is given to a child many times and the child adapts to the stimulus and stops reacting the same because the child is use to it and no longer interested. Used a lot in testing.
Stages of Language Development
2-4 months- cooing (gurgling sounds)
4-10 months- Babbling (constant vowel rep)
8-10 months- First gestures (Bye-Bye)
10-12 months- Comprehension of words and spoken sentences
12 months- first spoken word
