Reduce, reuse, recycle your vision: the basis of rich and stable perceptual experience

The visual world is cluttered, discontinuous, and noisy, but our perceptual experience is not—scenes appear rich, seamless, and stable. This seeming contradiction has posed a challenge for theories of perception for decades. In this talk, I will discuss two complementary processes that reconcile the contradiction: First, a mechanism that generates rich visual impressions by efficiently compressing clutter into summary statistical representations, and, second, a mechanism that recycles prior percepts to smooth and stabilize perceptual experience. Together, these mechanisms transform chaos into coherence and drive our impression of a vibrant, detailed, and stable world.
