Attention is captured by objects that they can pick up and place somewhere: in a row, stack, or in and out of a container. They evaluate the experience of placing an object, compare their current experience with prior placements, and decide if they want to continue placing objects, or not.
When a placement of an object is demonstrated, they will imitate the movement. Learning is limited to imitating a demonstrated direction, one action at a time.
Within ACL 3.4, repetitive actions seem to have a mesmerizing effect. Once they start doing an action, they may not be able to stop, which is called perseveration. Assistance to stop perseveration is provided by directing their attention to another action. Carrying around a Jacob's ladder is a good way to have a distracting object with you. The repetitive actions of the ladder are initiated by a manual action.
