00:01
We're looking at the stages of cognitive development.
00:04
When is the pre -operation stage? zero to two years, two to seven, seven to eleven, or eleven to twelve.
00:14
So there are four stages, and they are sensory motor, intelligent, pre -operational, concrete and formal.
00:24
So we go through them.
00:29
Sensory motor comes first.
00:31
So this is a newborn child.
00:34
Then we have the pre -operational, which is when we're looking at.
00:43
Then concrete, and then formal.
00:51
So formal is the most complicated.
00:53
So these approximately stick with some different ages.
00:57
We have, first of all, the sensory motor.
01:04
So sensory motor is when a child is first born, and they are basically learning their motor skills...
