11. Debriefing What was the longest series of numbers you could remember?
If you could remember 7, this is about average. Miller suggests that most humans can remember 7 plus or minus 2, so if you could only remember 5 or could remember 9, that is quite normal.
Can you think of any flaws of this study?
