Question pretext
Enumerator: read - i'd now like to play a game designed to measure your short term memory. It is not a test of intelligence. Listen carefully as i say some numbers. When i finish, you should repeat them back to me in the same order i said them to you. For example, if i say 7866, you say 7866. Or if i say 1112, you say? [wait for response]. I will read each set of numbers only once so be careful to pay attention the first time. If you miss what i've said, just try your best to repeat whatever you heard.
