# Remembering folk tales over time

## Problem

A psychologist asks individuals from England to read a brief Native American tale about a young man who joined a group of men fighting in a battle, only to discover that the battle was between ghosts. After participants read the story twice, the psychologist asks them to write down everything they remembered about the story. He follows up with the participants over the next five years, asking them one time each year to write down as much as they remembered from the story. Each time they wrote down their stories, he rated their accuracy on a scale of 1 to 100, with a rating of 100 indicating complete accuracy, and a rating of 1 indicating no accuracy. Table 1 outlines the average accuracy scores from participants at each timepoint.
