Question

As mitch walks through the greeting line at the conference, he meets 100 new people. we would expect him to remember the names of approximately ________ people.

Answer 1

We could take a good guess and say that he will remember 7 plus/minus 2 - so between 5 and 9 people.

This is the so-called magical number 7 psychology - the number of items we can remember without specifically repeating the material.

It's also likely he would remember the last people due to recency effect.
