Exploring Recommended Readings and Resources on Mind and Perception

We've all seen those illusions. The dots seem to dance, when in fact they're completely still. The lines look like they bend, but in reality they're perfectly straight. Here's the thing: It doesn't matter that you know the ground truth of these illusions—the dancing and bending won't stop. And that we see the world one way, even though we know it's actually another way, is a fascinating quirk of our minds—and maybe a telling one. It suggests that there's a chasm between perceiving and thinking, that these may be two independent provinces of the mind. But, if so, we're faced with another question: Where does perception end and thinking begin? 

My guest today is Dr. Chaz Firestone. Chaz is an Associate Professor of Psychological and Brain Sciences at Johns Hopkins University, and Director of the Perception and Mind lab there. He and his research group study perceiving, thinking, and the interface between the two.

Here, Chaz and I talk about his background in philosophy and how it continues to animate his research. We sketch the differences between perception and cognition and why the two are best considered separate faculties. We consider the idea of so-called "top-down" effects on perception. We discuss the fact that, even if perception and cognition are separate, there's much more to perception than meets the eye. We seem to see things like causes and social interactions; we perceive things like silences and absences. Along the way, Chaz and I touch on the modular view mind, skeletal shapes, the El Greco fallacy, stubborn epistemology, birders and radiologists, retinotopy and visual adaptation, adversarial images, human-machine comparisons, and the case of the blue banana. 

This is a fun one, friends. But before we get to it, one humble request. If you've been enjoying Many Minds, now would be a great time to leave us a rating or review. You can do this on Apple Podcasts or on Spotify. It would really help us grow and get the word out! It actually looks like our last review on Apple Podcasts is about 10 months old—so, if you have a minute, that could really use some freshening up.  

Alright folks, on to my conversation with Chaz Firestone. Enjoy!
