Assume a certain sequence of N characters, displayed on a screen one by one, that should be memorized. The speed of the display is such that it doesn't produce much extra stress. You may assume that the test person might vary display speed within a reasonable range.
There are several ways to test memory:
- a multiple choice format that presents several control sequences
- a control sequence where you should point out differences from a given sequence
- a control sequence, displayed character by character, and the opportunity to push a button as soon as you spot a difference
- just write down what you've memorized
Do these different ways of testing activate different parts of the brain? If so, where in the brain do these differences occur?
