Instructions to subjects:
Materials:

Scratch ’n’ Sniff cards
Scratcher (e.g., guitar pick)
Description: This task assesses the ability to identify various odors. Before identifying the
odors, the child participants are asked to identify the eight pictures that are used as answer
choices. Having identified the pictures, they are asked if they have tasted or smelled the objects
or foods depicted. 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.”
For this age group, there are two parts to the instructions: picture identification and odor
identification.

Public reporting burden for this collection of information is estimated to average 2 1/2 hours per response, including
the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and
completing and reviewing the collection of information. An agency may not conduct or sponsor, and a person is not
required to respond to, a collection of information unless it displays a currently valid OMB control number. Send
comments regarding this burden estimate or any other aspect of this collection of information, including suggestions

Part 1: Picture Identification:
The participant is presented with a screen that shows eight pictures: Popcorn, Flower, Lemon,
Play Doh, Bubble Gum, Chocolate, Coffee, and Cinnamon. Each question and a form to record
the child’s responses will appear one at a time on the examiner’s screen.
The examiner should say: “Now, we’re going to look at some pictures. I want to see if you
know what they are.”
Say: “Point to the picture of a Flower.” If incorrect, point to the flower and say: “This is a
Flower.” Mark correct (“Yes”) or incorrect (“No”) on the examiner screen.
Ask all participants: “Have you ever smelled a Flower?” Mark yes or no on the examiner
screen.
Say: “Point to the picture of Popcorn.” If incorrect, point to the popcorn and say: “This is
Popcorn.” Mark correct (“Yes”) or incorrect (“No”) on the examiner screen.
Ask all participants: “Have you ever tasted or smelled Popcorn?” Mark yes or no on the
examiner screen.
Say: “Point to the picture of Lemon.” If incorrect, point to the picture of the lemon and say:
“This is Lemon.” Mark correct (“Yes”) or incorrect (“No”) on the examiner screen.
Ask all participants: “Have you ever tasted or smelled Lemon?” Mark yes or no on the
examiner screen.
Say: “Point to the picture of Play Doh.” If incorrect, point to the picture of Play Doh and say:
“This is Play Doh.” Mark correct (“Yes”) or incorrect (“No”) on the examiner screen.
Ask all participants: “Have you ever smelled Play Doh?” Mark yes or no on the examiner
screen.
Say: “Point to the picture of Cinnamon.” If incorrect, point to the picture of cinnamon and say:
“This is Cinnamon.” Mark correct (“Yes”) or incorrect (“No”) on the examiner screen.
Ask all participants: “Have you ever tasted or smelled Cinnamon?” Mark yes or no on the
examiner screen.
Say: “Point to the picture of Coffee.” If incorrect, point to the picture of coffee and say: “This
is Coffee.” Mark correct (“Yes”) or incorrect (“No”) on the examiner screen.
Ask all participants: “Have you ever smelled Coffee?” Mark yes or no on the examiner screen.
Say: “Point to the picture of Chocolate.” If incorrect, point to the picture of chocolate and say:

Expiration Date: XX/XX/XXXX
Ask all participants: “Have you ever tasted or smelled Chocolate?” Mark yes or no on the
examiner screen.
Say: “Point to the picture of Bubble Gum.” If incorrect, point to the picture of bubble gum and
say: “This is Bubble Gum.” Mark correct (“Yes”) or incorrect (“No”) on the examiner screen.
Ask all participants: “Have you ever smelled or tasted Bubble Gum?” Mark yes or no on the
examiner screen.
At the end of these questions, the examiner’s screen will be refreshed with the names of those
pictures that were not correctly identified on the first trial. These items will appear on the
examiner’s screen one at a time, and are to be repeated with the instruction: “Point to the
picture of…,” and again the examiner will mark correct or incorrect, correcting the child by
saying: “This is….” (Note: the examiner should not repeat the “Have you ever smelled…”
question to the child.)
Part 2: Odor Identification:
For this age group, the examiner will scratch the card and hand it to the participant, saying: “I
am going to give you some stickers to smell. After you have smelled the sticker, click on the
picture that shows what you just smelled. If you want to change your choice, click on the
hand, also called the GO BACK button (point to the button on the child’s screen). Let’s
begin.” If the participant is having difficulty using the mouse, the examiner may operate the
mouse (see the note above).
NOTE: The child is not permitted to go back beyond the previous item he/she attempted. The
examiner should monitor this closely and if the child attempts to go back beyond the previous
item, say: “You can only go back to the last item you smelled.”
When the child has completed all six cards, say: “We are done with the smells.”
