What is it about?
Is Deese-Roediger-McDermott (DRM) false memory like true memory? How much of it comes from memory, and how much is just a matter of a calculated decision choice of whether to accept or reject the word in a recognition test? In this study, subjects were either restricted from making a free choice of test words, or allowed to make any choices they wished. Results showed that DRM false memory depends very much on what choice discretion people are given. When they did not have a free choice of test words to accept, they showed a very low level of DRM false memory. Hence, DRM false memory depends to a large extent on people's decision making, rather than reflects their memory of the critical word.

Why is it important?
Whether DRM memory is memory-based or decision-based has been debated for over 20 years. We have showed that a large part of the false memory is decision-based.
Perspectives
The results elucidated an important property of DRM false memory, and that is, that it is not the same as true memory.
