What You Know Changes What and How You See

Can what we know about an object change the way we see it? Or the way we feel about it? If so, could that be because different brain areas process different features of any given object, such as what we know about its uses?   In this episode of Under the Cortex, APS’s Ludmila Nunes speaks with Dick Dubbelde, a recent postdoc and adjunct professor of psychology and neuroscience at George Washington University, about how quickly and how well we process different objects. “In an environment such as surgery, where small spatial details are super important, or in an environment like driving, where reaction time is super important, those little differences can add up, especially at the societal scale,” Dubbelde explains. He explores this research more fully in an article he coauthored with Sarah Shomstein in Psychological Science: “Mugs and Plants: Object Semantic Knowledge Alters Perceptual Processing With Behavioral Ramifications.”
