3V1056.01 Counting objects for herself (12/6/80)
What I remember as significant about this episode was Peggy’s putting
her fingers and the number names into 1-1 correspondence. Now she
can “count” (as documented below) but the limits of her correspondence
appears to be TWO. But that fact that she attempts correspondence at all
shows a preliminary grasp of the relation and some sensitization to its applicability.
