Sensorimotor Schema
What is natural seems simple and it has already been learnt
For Piaget, a schema is a mental structure which enables to repeat the same
action or to apply it to new actions.
(a behavioural brick ...)
Piaget : specialist in Child learning behaviour, the birth
of the intelligence 1979
Imagine that you say to somebody that if he wants to stop
his computer, he first has to click on a start button ... that is not natural
at all, it is counterintuitive !
There is in it some parameter that describe a general
situation where you may want to use that schema
-
A schema is assimilating : you may apply it to new situations
-
The schema has a purpose
-
The schema is not a declarative knowledge : it is used and learnt unconsciously
Ex : When you grab an object, the same scheme may be used
in different situation
The behavioural interface is a mixed entity :
-
an artifact (material device)
-
a schema (mental process)
