Project Description

This work was supported by the National Institute on Deafness and Other Communication Disorders under grant R01DC008524-13S1 awarded to Brian MacWhinney.

A standard protocol is administered to participants with mild cognitive impairment (MCI) and those without cognitive impairments.

The protocol includes:

Picture descriptions -- Cookie Theft, Cat Rescue, "Going and Coming" (Norman Rockwell)
Story narrative -- Cinderella*
Procedural narrative -- Peanut butter and jelly sandwich
Personal narrative -- Hometown

*NOTE: The standard administration for this task involves having the Participant first look through pictures from the Cinderella storybook to refresh their memory of the story. The pictures are then removed before the Participant tells the story. In some cases, however,the Participant was given the option of looking through the pictures and chose not to. These are the Participants who did NOT look through the Cinderella pictures prior to telling the story:
MCI: 5, 10, 14, 15, 20, 21, 27, 28, 31, 33, 40, 43
Neurotypical: 3, 8, 13, 24, 30, 34, 35, 36, 38, 39
