The Serial Position Effect
Watch fifteen words. Then watch which ones your memory kept.
What this is
A memory test, and a real one. I will show you fifteen unrelated words, one at a time, about a second each. There is nothing to do while they play except watch. The moment the last word clears, I will ask you to type back every word you can remember, in any order.
Then I will line your recall up against the position each word held in the list and draw the curve your memory actually made. I am not going to tell you what I am measuring yet, because the reveal is the whole point. Just watch the words.
A note before we start
Since Ebbinghaus (1885) and Murdock (1962) JEP vol 64, free-recall studies have found that which words you keep is decided less by the words than by where they sat in the list. The shape that falls out is one of the most replicated results in all of psychology. You are about to draw it with your own head as the instrument. No prep, no strategy required. Letting it wash over you is a valid way to play.
