5 developmental cognitive neuro Flashcards
1
Q
timing of formation of myelinated cells
A
- oligodendrocytes generated in gestational period
- cortical cells become myelinated shortly after birth
2
Q
changes in cortical matter later in dev
A
- white matter rises (myelination)
- grey matter rises then falls (develop then prune those that don’t work)
3
Q
what does the fusiform gyrus do
A
face recognition
4
Q
which cells respond to directional biological motion in Macaque monkeys
A
S temporal
5
Q
nativism vs empiricism
A
- nativism: all concepts about world are inborn
- empiricism: mind is initially blank slate
6
Q
perceptual magnet effect
A
- at birth can discriminate phonemes
- ability improves to 6mo
- up to 9mo, sensitive to phonemes not used in their language
- by 1y sensitivity disappears
7
Q
do babies use facial or vocal cues more
A
- both together
- but if 2 choose 1, use vocal more
8
Q
“small world networks” and “rich clubs”
A
- small world > individual neural networks: high connection, short average path length
- rich clubs: longer pathways connecting neurons to each other too
