In this episode of Science of Reading: The Podcast, Susan Lambert is joined by Northwestern University Professor of Education, Social Policy, and Psychology David Rapp. David’s research focuses on language and memory, and his conversation with Susan gives insight into how memory is connected to comprehension. The first half of the episode is spent defining comprehension as a process, a product, and a higher-order cognitive process. David then digs into how that definition informs the ways in which educators assess comprehension and where they can look for potential failure points. One of these failure points includes misinformation. David addresses what happens when misinformation is stored in long-term memory. He details the issues this can cause for student comprehension, and he gives guidance on how to prevent and correct them.

Quotes:

“Once the information is in memory, you can't really get rid of it. What you can try to do is make other memories more powerful, more likely to resonate to things.” —David Rapp, Ph.D.

“Sometimes our most effective processes actually lead us to misunderstand. For example, you're really good at encoding information to memory, that's great, except if you're exposed to inaccurate ideas, that's a problem.” —David Rapp, Ph.D.

“It feels easy for us to comprehend texts if we're well practiced at it, it feels easy, but it's actually a lot of cognitive operations going on behind the scenes and a lot of years of practice.” —David Rapp, Ph.D.

“In terms of being exposed to misinformation, we see even if people have been exposed to inaccurate ideas, even once, it's encoded into memory, it's potentially gonna be there to influence you.” —David Rapp, Ph.D.
