Types of inferences explained

In this episode of Science of Reading: The Podcast, Susan Lambert is joined by Kristen McMaster, Ph.D., Guy Bond Chair in Reading and professor of special education in the Department of Educational Psychology at University of Minnesota. Together, they explore how reading comprehension isn't just about what's on the page—it's also about what's not there—and share practical insights on how to support students in developing inference skills. Susan and Kristen also discuss the dual processes of activation and integration when making inferences; the distinction between teaching students to process text actively versus teaching students to apply comprehension strategies; and different types of inferences, including causal, bridging, and elaborative.
