ACL 4.8 displays an awareness of directionality that is absent at ACL 4.6.

Score

The tentative score is ACL 4.8.

Test their ability to hold an image in their working memory by colouring the diamond and timing intervals between looking at the sample.

All of these errors display difficulties with directionality and three dimensional space.

Score

The tentative score is ACL 4.6.

Test their ability to hold an image in their working memory by colouring the diamond and timing intervals between looking at the sample.

The ability to hold an image in the person's working memory means that they are able to correctly identify where the pitchfork, shovel, lettuce and tomatoes were located.

Score

The tentative score is ACL 4.6.

Being able to sustain their ability to continue matching until the design is complete is the scoring criterion. They will keep referring to the sample until each piece is placed and the design is complete.

Score

The tentative score is ACL 4.8.

Being able to overlap an object over another is the scoring criterion.

Being able to hold an image within the person's working memory results in the ability to compare the images and hide one tip of the rhombus under the corner pieces. The person will stop referring to the sample when their mental energy is all used up. This is when errors occur.

Score

The tentative score is ACL 4.6.

Reading with verbal directions does not supply enough information and must be supplemented with a demonstration that can be imitated.

The person can read the instructions but cannot form a mental image of what they need to do on their own.

The person can follow a demonstration of cutting a triangle piece using the template, pealing the paper backing on the Heat n' Bond and ironing pieces into place.

They are likely able to go ahead with making the windmill pattern after asking for verification for each step.

Reading with verbal directions does not supply enough information and must be supplemented with a demonstration.

The person understands that they are there to make something but will lack the ability to stick to the task without verbal prompting and demonstrations per action as they do not understand a series of steps.

The person required a demonstration of cutting a triangle and peeling the backing and then ironing on a piece, demonstrating one step at a time. They should be able manage the task with this level of support.

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.

They refer to the sample for each tile placement.

Spacing is inconsistent.

When using Design D, they may mix up the green, purple or blue colours. The picture above shows one possibility of mixing the colours up.

This is a surface appearance error.
