The concept of doing an activity is a classification of at least three steps or actions to complete a goal. Within ACL 3.8, the goal is partially understood by the idea of being done, but they do not really have an idea of what the finished project would look like. Without an idea of what the finished product ought to be, they lack a standard of performance and their completed projects are a mess of obvious random actions. The classification of doing an activity is incomplete.
Stamping a note card displays the difference between attention to the process versus attention to the finished product. The first snapshot is of what the note card often looks like when done by a person functioning in ACL 3.2, 3.4, 3.6, and 3.8 in order from the top left.

The second snapshot is typical for ACL 4.2, 4.4, and 4.6, and the increase in organisation is apparent. (I left out ACL 4.0 because "typical" has several variations).

The point is that the ACL 4 concentration on doing an activity produces an organised design. The ACL 3 concentration does not produce a product that anyone particularly cares about, which is fine. We can plan on using inexpensive materials that can be thrown away or only loved by a loved one.
If you watch carefully, you can observe that during the process the people functioning within ACL 3.8 seem to get stuck in the process of repeating a manual action. People tend to perseverate on a single action within ACL 3.4; a few still perseverate within ACL 3.6; and they can usually break themselves out of perseveration within ACL 3.8. But, they are still focusing their attention on the repetitive action and are apt to find it very hard to stop before they are finished. When they finish, they often sit back in the chair, fold their arms, and take a deep breath. Perhaps it is a sigh of relief at having gotten done.
Post-It Notes
Post-it notes can be placed in a row within ACL 3.4. Observations with post-it notes would probably be similar to the copying activity in the ACLS-6. You would need to add a frame for ACL 3.6 through 4.4. A 6 inch (15 cm) square tray will work. The difference between tiles and post-it notes is that the latter are not reusable. Within ACL 3.8, they are apt to use all of the post-it notes that you give them, one at a time. If you want to sustain attention, that is great, but if you need to leave work on time to pick up the kids, that is terrible.

Sorting
Many people can learn how to put three steps together within ACL 3.8. Learning is limited to manual actions that have a perceivable effect on material objects that can be repeated. The actions that have been discovered include sorting, matching, stacking, folding, stamping, and gluing. The rule that seems to hold is no more than 3 actions at a time.
The piles of paper clips are evidence of freeing themselves from perceptual, linear properties. The concept of colour forms an independent classification that exists in their mind and on the table. One of the fascinating things to observe is how closely people stick to the presence of material objects to form their elementary concepts.

Without any intention of using the objects, hair ornaments are safe objects for sorting by colour.

Men and women may enjoy sorting colourful objects and hair ornaments are inexpensive, washable, can avoid swallowing hazards, and can be handled by clumsy hands. If infection control becomes a problem, they can be issued to individuals and washed in the facility laundry in a mesh bag.
The purple sorting tray is good for grouping different types of hair ornaments, which comes into the scale in ACL 3.8.

A sorting tray is not so important if these hair ornaments were to be sorted by colour because colour comes into the scale in ACL 3.4. Within ACL 3.8, they may be able to assume placement in a group by the location on the table top.
