Administration Time (in healthy volunteers): 5 Minutes
Cognitive Domain Usually Measured: Verbal Learning & Memory
The phrase "Shopping List Learning" is displayed on screen. The pre-task on-screen instructions tell the test supervisor to start this task with the screen facing the supervisor so that the subject cannot see the screen.
The subject is told by the test supervisor: "In this task, I am going to read you a shopping list. I would like you to remember as many items from this list as possible. Are you ready to start?"
To begin, the test supervisor presses the "ENTER" key. The test supervisor reads the list of words as they appear on the computer screen at a rate of one word every two seconds.
When the test supervisor has read all the words they ask: "Tell me as many of the items on the shopping list as you can remember?"
As the subject recalls each word, the test supervisor clicks the appropriate button on the screen with the stylus or mouse.
If the subject says a word that was not on the list, the test supervisor will click "Other Word". If the subject repeats a word, the test supervisor will click the corresponding button as many times as the word is said. If a button is clicked by mistake, the test supervisor can select "Undo Last" and then continue recording.
Trial 2 (and subsequent trials)
When the subject cannot recall any more items then the test supervisor instructs, "I am going to read you that same shopping list. Try and remember as many items as you can. Are you ready to start?
The entire word list is read again, in the same order as it was read previously. To begin, the test supervisor presses the "ENTER" key and reads the list of words as they appear on the computer screen at a rate of one word every two seconds. When the test supervisor has read all words they ask: "Now what were the items on the shopping list?"
Again, the test supervisor notes the items recalled by the subject by clicking/touching the corresponding button on screen with the stylus or mouse.
In the standard version of this test, 3 learning trials are presented following this format.
The difficultly level of this task can be adjusted by presenting less or more words. The list of words can be anywhere from 2 to 16.
Primary Outcome measures:
Unit of measurement: Number of correct responses
Description and interpretation of scores: Total number of correct responses made in remembering the list on three consecutive trials at a single session. (Higher score = better performance)
