SUMMARY: SENSORIMOTOR SUBSTAGES Talked about 6 subbstages (birth to age 2); looking at creation of mental thinking of babies  Substage 1: Think with their bodies (reflexs; practice what they were born with and hone these skills) because that’s what they’ve got to start with  Substage 2&3: Body and object centered reflex use: You happen upon an action by accident but you repeat it because you find it pleasureable (eg: sucking your thumb, squeeze a rubber ducky etc.)  Substage 4: start of intentional behaviour (8-10 months); start coordinating secondary schemes and you use a bunch/group of single schemes you’ve learnt to attain pleasure (the schemes on their own do not bring pleasure but together, they do) o Trying to assimilate the new objects into already existing schemes (trying to engage in serious learning about the world) o Put together schemes to get to goals  Substage 5: Create new ways of getting interesting results (do other schemes to already known schemes to see if there is anything else they can figure out about it); trial and error => they act out everything and they don’t do it in their head  Substage 6: Schemes go mental; i.e. problem-solving o The difference between Substage 4 and 6 is in 4, they don’t know that, what they are going to do, will result in what will actually happen (they will see what happens when they do it). In substage 6 they can think and figure out what will happen before they do it, all in their head.  PICTURE REPRESENTATION OF PRIMARY, SECONDARY AND TERITIARY REACTIONS (COPY) SENSORIMOTOR STAGE ACCOMPLISHMENTS  Capstone accomplishment o Beginnings of symbolic thought (schemes, mental representations etc.)  Skills that reflect this accomplishment? o Deferred imitation  Piaget felt that you couldn’t imitate till Substage 4 (8-12 months) and he said even then you’re not good at it BUT this is probably more motor development over cognitive development (but Piaget didn’t know about it then)  Some babies aren’t able to do it due to lack of motor experiences  Researchers see that motor development isn’t very good at substage 4 but develops VERY quickly at substage 5  NOTE: imitation is NOT the ability to use symbols but DEFERRED IMITATION is  Deferred imitation is when you don’t do the action immediately, right in front of the imitatee but you do it later (hours later maybe), when the imitatee is gone.  Eg: Piaget’s daughter saw another kid throw a temper tantrum when he was trying to be taken out of the crib; he stomped his feet; cried etc. A few hours later, when SHE had to be taken out of the crib, she did the same actions.  Eg: Collie and Hanes; model presses a button that does something exciting and baby is allowed to see this. A day later, the same button is presented and the baby
