When talking about infancy, we are talking about 0-2 years

When talking about nervous system development the midbrain is most fully developed at

birth

All our lobes develop much later in time it’s just the midbrain which are most developed

As infants we are born with reflexes

-they are behaviors necessary for us to survive in grind behaviors which are necessary for our

survival

-they are mostly controlled by our midbrain

- Some adaptive reflexes tend to disappear over time or transform as child learns new

skills

- Rooting it’s important for signaling feeding, they have sucking reflex, but you have to

signal when they should be eating

- Babinski related to the neural connections of the legs and disappears when child

learns to walk

- Moro also known as the startle reflex, the motor reflex is important for grabbing

behavior and signaling that person is being startled or shocked

- Depending on cultural background there are some evidences that suggest that some

cultures prefer sleep training or some believe not to respond to children when they

wake up crying

- -the key to all behavioral states and working with infants is consistency

- -regardless of your cultural beliefs, you need consistency

- -the role of caregivers is to create a predictable environment for the child

, - -inconsistency can create attachment issues, we need synchrony

- Crying is the first form of communication

- Crying behavior changes after 6 weeks

- -within these first 6 weeks where they are interested in colic, which is random crying for

3 or more hours a day for several months

- The most developed sense that infants have--> touch and closely after is hearing ‘

- -lest developed sense sight

- Aspect of vision that is most developed in infants is  eye tracking

- -its initially inefficient bu8t within n couple of weeks it develops well, especially things

close to them

- Color vision by 2 years old is identical to an adult

- Depth perception increases rapidly, slows down and then increases again, there’s

stages to depth perception. Related to how mobile a child is in terms of exploring the

world. Child first learns to crawl so when they do they have a certain perception of the

world then when they stand up, they must change perception of depth cuss perspective

of world changes since they are now standing. Their perceptions are changing

- Visual cliff task  used to study depth perception

- -aside from the objective of task the study was made to come to different conclusion, it

initially started to study fear and how they learned fear but over time we found it has

nothing to do with fear

- -just have general understanding of purpose and goals of cliff test

- -watch the video
