The first line is between their hand and the object. Reaching out is a conscious decision to grasp. Procedural memories for different forms of grasp that the person learned to do by habit are observed with most people who have a cognitive disability. A conscious decision can also be made to put the object down or hand it to another person.
When they throw something at a target, the line is between the object and the target.
Independence in blowing bubbles probably enters the scale within ACL 3.0.
The motivation for intentional reach and pinch is high when marshmallows are the target. One to three small ones will probably get the dietician's approval.
When marshmallows fail, rearrange your schedule because finding an object that stimulates intentional reaching is apt to be a time-consuming challenge.
It sounds nutty to outsiders, but "marshmallow failure" is alarming to those of us who search for activities that they can do.
