If they are not demanding assistance or refusing to comply, the general public tends to forget about these people too.

Many of these people are slow and quiet and easily overlooked. If so, staff members may appreciate the warning that it is easy to forget about these people.

Avoid overwhelming the person by only discussing one topic at a time. Ask them one question or give them one choice at a time. Giving them several choices at a time or talking about several topics will likely cause confusion and may escalate to anger.

An emergency escape route can be planned and rehearsed but the chance of them recognising and calmly following the plan during a real event is questionable.

Carers need to coordinate with a pharmacist to ensure adequate medication supply and assist with renewing prescriptions.

Two questions characterise ACL 4.2: "What's next?" and "What day is it?" They are apt to interrupt others and demand assistance / answers now.

All cultures have word taboos; the taboos are usually followed within ACL 4.2. When the taboo is broken, it is probably done knowingly.

Universal Social Customs

Universal social interaction rules may be programed into the DNA. It is certainly fascinating to find the following rules in many different cultures and entering the scale within ACL 4.2.

Social conflicts begin to enter the scale within ACL 4.2 because they have enough sense of self to argue for their personal rights. The problems are that they have a very narrow perspective and very little understanding of the meaning of compromise. Arguing is seldom effective. Distracting and diverting attention works better. The person is easily overwhelmed with information. Keep questions to one topic at a time. Wait for a response from the person. If the person is overwhelmed, be prepared to talk about easier topics such as the weather.

The person usually follows simple demonstrations that match one striking feature. A striking feature is colour, shape, size, number of items (up to four), and linear information. Their visual field is still limited to placemat size, but they can find items used routinely when they are stored in familiar locations.

Within ACL 4.2, the person's use of gross eye-hand coordination is a bit firmer and less clumsy than ACL 4.0. Any attempts to change the location of small material objects are typically done for one feature at a time.

Tentative Eye-Hand Adjustments

Simple pinch and grasp is used to make adjustments in the placement of objects, with weak pressure and slight changes in position.

Within ACL 4.0 and 4.2, horizontal (ACL 4.0) and vertical (ACL 4.2) stripes are not as good at differentiating between the modes as the checkerboard is for ACL 4.4. The vertical stripe in ACL 4.2 is a bit awkward because it emerges out of a failed attempt to do the checkerboard pattern. The first row of alternating colours in the checkerboard pattern emerges into vertical stripes in the 2^nd row. The 2^nd row starts the vertical stripes that might be followed until all of the space is filled or stopped when they notice that theirs does not look like the sample.

A willingness and capacity to comply with a standard of performance is the major social difference observed within ACL 4.2. The opposite is the complication.

Time

The person is aware of the passage of days and asks what day it is and what today's date is. They keep regular sleeping hours and anticipate meal times by watching external events.

Eating and completion of other activities is so slow that other people must adjust to two to three times the normal rate and others need to wait that long as well.

Within ACL 4.2, the person is able to match to either a sample or to a familiar task using one striking feature at a time. A striking feature is colour, shape, size, number of items (up to four), and linear information.
