Description: This task assesses the ability to identify various odors. All participants use scratch
’n’ sniff cards and after scratching them, are asked to identify which of four pictures on the
screen matches the odor they have just smelled.
If a participant has difficulty using the mouse, he/she may point, and the examiner may
operate the mouse. When this happens, the examiner should say something like the
following to the participant: “You can point to the picture you want, and then I will
use the mouse to click on it for you.”
Before beginning the task, the examiner says: “This task involves smelling various odors, one
at a time, and then trying to identify them. The odors that you will smell are chosen from a

variety of foods and objects that people experience in everyday life. We are using ‘scratch
and sniff’ cards to present the odors.”
The examiner continues: “Take this scratcher and scratch the first card; smell it, then look
at the pictures on the screen. Click on the picture that best shows the odor that you
smelled on the card. A new set of pictures will appear on the screen and you will be asked
to identify the odor on the next card. If you want to change your last answer, click on the
GO BACK button (point to the button on the participant’s screen).”
The examiner should repeat this sequence of handing the cards to the participant to scratch,
smell, and identify until all the cards have been used. For each trial, repeat what was said above,
as needed: “Take this scratcher and scratch the card; smell it, then look at the pictures on
the screen. Click on the picture that best shows the odor that you smelled on the card. A
new set of pictures will appear on the screen and you will be asked to identify the odor on
the next card. If you want to go back to change your last answer, click on the GO BACK
button.”
NOTE: The participant is not permitted to go back beyond the previous item he/she attempted.
The examiner should monitor this closely and if the participant attempts to go back beyond the
previous item, say: “You can only go back to the last item you smelled.”
When the participant has completed all 10 cards, say: “You have finished this activity.”
