. What would you like to do?
Biological mechanism that protects the brain when malnutrition affects body growth. The brain is last part of body to be damaged by malnutrition
Unused connections in the brain atrophy and die
Experience-expectant brain functions
Functions that require certain basic common experiences in order to develop normally
Experience- dependent brain functions
Functions that depend on particular experiences that may/may not develop in particular infant
Push middle toe, baby clamps foot
Baby on its tummy will "swim" in crawl like way
Once "fake" dropped or swooped, baby will instantly try to grab something with their feet/hands
Continuous stimulus will make baby block out the stimulus (ex: falling asleep and being able to sleep through particular stimulus)
Signs of Over Stimulation
- -the universal stop sign for NO
- -tongue thrust-spits put pacifier, just place finger in their mouth to help them get back into rhythm then (give pacifier)
- - hiccups (give them pacifier)
- -gaze aversion- (give pacifier)
- -habituated- puts themselves to sleep
Way to Calm a Baby or 5 S's
Phases of Crying
- A: Expiration
- B: Inspiration
- C: Rest
States of development
- 1.) deep sleep
- 2.) light sleep
- 3.) drowsy
- 4.) Alert- Attentive
- 5.) Alert- Active squirming
- 6.) Alert- Crying
Slow brain development
- -decreased weight gain
- -funny sounding cry
- -trouble transitioning between developmental states
- -unable to self soothe
- -abnormal reflexes
Infants born 'perm' have the most brain neurons than any other life stage
Within the first 3 years of life, brain makes continuous connections
Speeds transition of impulses, makes brain speed faster

Shaken baby syndrome
Life threatening injury that occurs when infant is forcefully shaken back and forth
Reason to pursue a goal that comes from inside a person
Example: imaginary friend dialogue, toy dialogue
Reason to pursue a goal that arises from the need to have ones achievements be awarded from outside

Limbic system, emotions.
Mildred Parties five kinds of PLAY
- 1. Solitary Play
- 2. Onlooker Play
- 3. Parallel Play
- 4. Associative Play
- 5. Cooperative Play
A child plays alone, unaware of any other children playing nearby
A child watches other children play
(seen around 2 years of age) Children play with similar toys but not together
(around 3yrs), Children interact, observing one another and sharing material, but their play is not mutual
(4 years), Play together, creating dramas or taking turns.
Explain Mary Ainsworth "The Strange Situation" Lab Test that proved Stranger Wariness
She tested that baby used parents as a 'secure base' when playing. If baby would check if the mom was ok with something, they were positive for stranger wariness and healthy.
Bowlbys three stages of attachment
- 1. Indiscriminate attachment (birth-6wks)
- 2. Focusing on Familiar attachment (6wks-6mos)
- 3. Active Proximity seeking attachment (6mos-24mos)
Three Cognitive Progressions of PLAY
- 1. Functional Play (sensorimotor) birth-2yrs
- -mouthing, throwing, cause/affect toys
- 2. Constructive Play 2-6yrs
- - Goal oriented (to paint -> picture)
- (build -> a tower)
- 3. Make believe Play 3-6yrs
- - Playing 'HOUSE' etc.
3 Categories of temperament, developed by Thomas & Chess
- 1. Easy
- 2. Difficult
- 3. Slow to warmup
Easy Child Temperament
- Adapts easily
- Positive mood
- Mild reaction
- High in regularity
Difficult Child Temperament
- Doesn't like change
- Low adaptability
- Intense emotions
- Very irregular
Slow to warm up child temperament
- Reaction to withdraw
- Regular habits
- Mild reaction
- With patience, they react like easy child
- If pressured, they react like difficult child
9 Temperament Characteristics

Temporary increase in dendrites in the brain within first two years.
