One man we learned about (H.M) was asked to practice drawing the outline of a star while looking at his hand in a mirror. With practice, he was able to complete this task more easily over time. However, each time he was asked to trace the outline of the star, he was never able to recall that he had already done this task on previous days or weeks. Instead, he was surprised by how easy it was. What would cognitive psychologists say that this shows us?
