Storing an image in short-term memory is indicated by studying the sample and never or rarely referring to it later (requires more observations). While colouring, their movements are fluid and continuous.

Organising a method of colouring requires the recognition of adjacent triangles that are the same colour. Colouring across triangle lines in red and yellow is observed.

Use Design C from the copying activity to confirm or rule out ACL 5.0.

Score

The tentative score is ACL 5.0.

The mental effort to form an image of the sample and compare it their picture is usually sustained long enough to complete this design.

The consistent seconds between looking at the sample indicates that the image was not stored in long-term memory. In addition, no improvement in the speed that the person applies to colouring in the triangles is expected during the colouring session.

Score

The tentative score is ACL 4.8.

Forming an image of the sample to compare to their pictures seems to take more mental effort that most people cannot sustain long enough to complete this colouring. Diminishing mental energy seems to explain shorter interval times between looking at the sample, not looking at the sample anymore, or the onset of making mistakes.

Score

The tentative score is ACL 4.6.

The ability to prevent mistakes is applied by the person by looking at the sample often. A mental representation of the sample (image) is formed and used to compare with their uncolored design.

Select the behaviour that most closely matches your observations:

Pick up the uncolored design and introduce the activity by saying:

After they look at it, put the sample on the table. Watch their face to be sure that they pay attention to the following instruction.

Point back and forth between the blank and coloured design twice, slowly.

Ending the Activity

The activity ends when the person has finished the picture.

As with all of the ACLS activities, record the date and time of day because they frequently explain inconsistencies between different activities.

Introducing the Activity

Place the materials on the table in front of the person. Position your chair so that you can see their eyes if or when they look at the sample and count the time intervals between looking at the sample.

During the Activity

After you give the directions, do not give any further instructions.

Do not initiate by saying anything else or pointing to anything.

The following materials are required:

• Red, yellow and green twist crayons.
• 
• A coloured sample for them to copy.
• A blank sample for them to colour in.

The diamond colouring activity can be used to differentiate between ACL 4.6 to 5.0.

Do NOT use this activity if the person cannot tuck in the clover or kite activities.

Completes the design with consistent spacing.

The spaces between tiles are spatial properties.

If they noticed the spacing after being cued, try the maple leaf activity.

Score

The tentative score is ACL 5.4.

Copies this design without consistent spacing.

They do not mix up the green, purple or blue colours.

Try the peanut butter or shading activity to differentiate between ACL 5.0 and 5.2.

Score

The tentative score is ACL 5.2.
