Classification, within the ACLs, is the organization of material objects and actions into groups. The simplest groups are formed in ACL 3.6 by sorting material objects that are alike, one criterion at a time. Striking colors, elementary shapes and easily seen differences in size are the features that capture their attention.
The concept of all of the objects or all of the space captures their attention within ACL 3.8. Classification is still closely connected to the perceivable features of the material objects that are in front of them.
Carabiners have a spring hinge side, are sold in dollar stores, and are used to clip things together. Originally invented for mountain climbing, they are apt to be unfamiliar to many people. Use is easily imitated by pushing on the side, which opens the clip and must be held open. The spring automatically closes the clip.
Having never seen a carabiner before, most people will be able to imitate opening and closing the ring in ACL 3.2, after a demonstration. If they have used one before, they will probably open it spontaneously. This observation supports the idea that there is not much functional difference between procedural memories and learning through imitation.
The difference between a procedural memory and imitation may be nothing more than doing something spontaneously or after a demonstration. If that is true, we do not have to be so limited by the person's history, which would be a relief in ACL 3 because they do not speak long enough to give us their perspective on their past. Few family members can be expected to know specific details about the individual's experience, specialized equipment, such as with carabiners, unless they were mountain climbers. If they shared them at home, then of course, they would probably know.
Sets of clips come in different sizes and colors for sorting. Black and silver will probably capture attention within ACL 3.6.
Shallow storage bins for paper clips are common in the dollar stores. Be sure to keep them shallow so people can see into them without raising their chin from their chest.
Zip-lock bags in a snack size make it easier to see the contents. When they cannot get a zip-lock open independently, they may sit, immobilized in a group. The leader must be sensitive to their need for assistance. They are not apt to put anything away within ACL 3.
