|
Brain develop begins
|
within 18 days of conception
|
|
|
First sensation to develop
|
touch
|
|
|
All of the brain neurons are developed within
|
the first six months of gestation
|
|
|
Genes and environment/experience
|
Genes define where function is located in the brain; environment influences how specific connections are made
|
|
|
"order" of development:
|
sensory, emotional, motor, cognitive
|
|
|
Development of systems: Birth to four months
|
-Birth Lower Brain-breathing, motor control
-2 mths. Motor Cortex-suppress relfexes, increase volitional movement -3 mths Visual Cortex-visually focus near and far -4 mths Limbic System-emotion, memory |
|
|
Development of systems: 5-14 mo
|
-5 mths Frontal Cortex/Hippocampus-remember/ associate stimuli
-8 mths-Prefrontal Cortex-forethought/gestures -12 mths-Temporal Lobe-Symbolic language context bound -14 mths-Temporal/Parietal Lobe-Symbolic language by concept |
|
|
Nursing rehearsal begins in utero
|
Flexion,
28-30 weeks gestation: suck pads developed rhythmic suck/swallow/(breathe), digestive cycles |
|
|
position of larynx
|
infant larynx directly behind mouth, adult larynx below mouth
|
|
|
habituation
|
ability to exhibit selective attention, filtering "familiar" stimuli in order to learn new
|
|
|
Motor control: 3-6 mo
|
Suppress primitive reflexes as volitional motor control
|
|
|
Neuron pruning
|
?
|
|
|
Body position maturation
|
supine, prone, upright (stacking), wobbling,
|
|
|
Oral stimulation
|
by 4 mo up to 4 hrs finger sucking and face-mouth examination.
|
|
|
Suppression of oral reflexes
|
Gag, Volitional control of Tongue, bite reflex
|
|
|
Self regulation stage
|
~6 mo, synchronous vocalizations as part of interaction
|
|
|
Communication 3-6 mo
|
-anticipates/reaches to be picked up
-focuses attention with more ease -awareness of strangers/strange situations -Quantity and variety of sounds increases but connected with body movement. -Tootheruption promotes lingual-dental (tongue and teeth), labial dental (lip and teeth) sound play. -Interested in own speech. Uses tone to create sounds to protest and call attention to self. -Attempts to imitate gestures and pitch changes in other’s voices. |
|
|
Communication: 7-9 mo
|
-waves
-mama and dada -bangs objects together -pointing -turn-taking routines -object permanence -imitating nonspeech sounds -vocalizing different states (anger, etc.) |
|
|
Synaptogenesis
|
-Between 8-10 months a burst of synaptic
growth yielding dramatic changes in several cognitive and social domains. -Imitation of others and intentional communication become robust |
|
|
Eye-hand coordination
|
increases independent play
|
|
|
10-16 mo
|
Interactive reciprocity
|
|
|
Communication, 10-16 mo
|
-Back and forth exchange of affect, sounds and word driving language
-Long chains co-regulated, reciprocal interactions. “Conversations without words” -Emerging complex problem-solving basis of conversational ability -Sound production now beginning to be separated from body movement |
|
|
Communication, 10-16 mo cont.
|
-Can follow simple requests and one step directions (“give me”,
“stop”) -Responds immediately (stops/looks) when name is called -Shows affection -Responds to praising/angry tones -Uses a wide variety of sounds and jabbers loudly -Emerging point/gestures with hand -Knows 3 body parts -May say first words |
|
|
16-18 mo
|
Communication Affect stage
|
|
|
Communication 16-18 mo
|
-Points with index finger
-Uses gestures to direct attention -Watches other children play. May imitate or play side by side -Repeats new words -Imitates new sound sequences |
|
|
Communication, 16-18 mo, cont.
|
-Able to say about 5-10 words
-Associating words with experiences -Intelligibility bound to context- about 25% intelligible to strangers -Conventional object play with trial and error, sorting and grouping -Attending to books, pictures |
|
|
18-24 mo
|
Representation of Affect stage
|
|
|
Communication 18-24 mo
|
-Forming sense of "self"
-Creating ideas and building logical bridges between ideas -The child’s affect (wishes and desires) generate to words and play. This will lead to creating logical and abstract verbal concepts -Uses jargon with some true words embedded -Responds to simple commands without gestures (come here/sit down) -Imitates words spoken by others -Says approximately 20 words |
