At any given moment, our retinas receive millions of bits of information. This presents a monumental computational challenge to the visual system. Rather than process everything our sensory systems receive, we rely on heuristics to reduce computational load. My research centers around one such critical heuristic: ensemble perception, which refers to the idea that we can represent sets of objects using summary statistics. Instead of seeing every single leaf on a tree, we tend to see its overall ‘leafiness.’ We see averages everywhere, even within a crowd of faces. Given limited viewing time, we see the average instead of the individuals. This makes some intuitive sense — The visual system exploits the natural redundancy present in the world (e.g., most leaves are quite similar), which allows us to quickly represent a vast amount of information.
