!> sensori substages"
!- the reﬂex schemas ( sucking, looking, hearing) "
!!e.g. breastfeeding ( baby practice on it)"
Primary circular reactions"
!- you do sth and you like it so you keep doing it"
!!e.g. suck on their toes; sucking thumbs; blowing bubbles "
!- its primary coz it only do with their body"
!!e.g. when baby snoring "
Secondary circular reactions"
!- interact with object in the world"
!- like a loop coz they do it over and over again"
Coordination of secondary circular reactions"
!-younger than 8 month lack of object permanence ( they know that the object is here ! !
even they cant see them) "
!- combine previous schemas"
!!e.g. do one thing in order to get something ( pull paper to get keys)"
!- imitates action"
!!e.g when baby wave byebye (like their grasping schemas)"
!- A not B error ( maybe bb just get used to it in a automatic mode of reaching the same
!! e.g. baby reach the old place even the key is being put in the new place (and ! !
they saw it too) "
tertiary circular reaction"
!- still focus outside world"
!- experimenting actively"
!! e.g. squi the rubber duck and found that cute so the bb try more method
to get the rubber duck 叫"
!!e.g. Throwing food ( exploration of the world)"
!- no A and B error "
Intervention of new means thru mental combinations"
!- ﬁrst time they work out problems in their head"
-they not longer limited to immediate experiences"
!- delay imitation ( think back to the past)"
!- visual imagery in problem solving "
!! e.g. bb holding ﬂower when pulling the door; she understands if you pull the ! !
door it is going to knock down the ﬂower ( they imagine what happened without actually
doing it) "
!- symbolic play "
!!e.g. use sponge to imitate for phone"
!> limitation of preparation though"
! ! - child can only focus on one thing (centration)"
!!!e.g. class inclusion:: "
!!!- children trouble understanding one part of sth and whole group of sth> !
!!!7 buttons, 2 red and 5 blue -> Ask them whether the whole set is more !
!!!or blue more; on this age, children will answer blue buttons are more "
!!!e.g. conservation tasks::"
!!! playdoh rolled in round or stick; they will think the stick one is more !
!!!becoz its taller; the water cylinder too"
-she showed us video of kids on water cylinder and quarter counting"
(quarter counting: 2 rows of quarter, they think the row that is more far away has
more quarters) << conservation tasks"
