Secondary Effects
The set of some plastic adhesives is a consistency of materials that is not perceivable. The instructions typically include waiting a period of time. Not waiting produces a secondary effect. The primary effect is holding the pieces together. Anticipating secondary effects enters the scale within ACL 5.8. Independently following the instructions to wait for the adhesive to set will probably occur.
The size of the material objects that the person can safely move around is bigger, but seems to be limited to the size of the adult body. Safe movements require images of what might happen during the movement.
The objects that may be used independently and safely include:
- Carrying ladders.
- Swinging garden tools such as rakes and leaf blowers.
- Moving a lawn mower into a tight space.
- Swinging baseball bats, tennis rackets and golf clubs.
Moving the whole body in a coordinated relationship with a stable material object includes:
- Jumping off a low diving board.
- Jumping over obstacles less than ankle high.
- Balancing on a narrow, raised surface less than ankle high.
- Climbing over obstacles no higher than 1 yard (1 meter).
- Climbing up and down ladders no higher than 2 yards (2 meters).
