Now show the person the shovel picture B.

Ask:

Can the person recall where the pitchforks and shovels are located?

Continue showing the person the shovel picture B for a further 5 seconds.

Introduce the activity by saying:

Show the person the shovel picture A

for 5 seconds.

Object Permanency is an awareness that objects continue to exist even when they cannot be seen, heard, or otherwise sensed.

The question is: Do people within ACL 4.6 remember where things are once they have been hidden?

Answers to all of the questions you ask the person must be 100% correct.

The following materials are required:

• A printout of the shovel PDF.
• OR
• View the shovel as a slideshow.

This activity is in pilot testing phase. It is subject to change. Please confirm score with another activity.

The shovel activity is used to confirm or rule out ACL 4.6.

The person is able to recognise a surface appearance such as the use of shading in a sketched picture.

The person is able to colour the whole apple in.

Score

The tentative score is ACL 5.2.

The inability to see surface appearances means that slight changes in the shaded area do not capture the person's attention.

The end result is that the person does not colour the whole apple in.

Score

A score has not been confirmed but rather ACL 5.2 has been ruled out.

Select the behaviour that most closely matches your observations:

Give the person the printout of the sketched apple and say:

The question is: Do people within ACL 5.2 see subtle changes in the intensity of colours required to shade a picture?
