Attention span may be within normal limits of 60 to 90 minutes when the concrete materials are fitting together as expected.
Frustration tolerance when things are not fitting may be short. The person is apt to quit within minutes of the encounter. Distracting them with a different, simple activity often helps them regain their composure. The person should not return to the frustrating activity until their heart rate has returned to normal. If frustration mounts again, the activity is too difficult for the person and both should be re-evaluated.
