Franklin's technique takes advantage of several learning-related effects:
- Generation/testing effect: without looking at the actual example piece of writing, he attempts to produce an imitation, i.e., he attempts to generate the piece of writing himself.
- Spacing effect: before trying to produce the imitation, he leaves aside the example piece of writing for some time so that he forgets it to some extent.
