The Power of Perception and Assumptions
Our perception of the world is actively constructed by our brains, which make assumptions and interpretations based on limited data. The famous example of 'The Dress' illustrates how different people can perceive the same image in different colors due to their brain's assumptions about lighting and fabric. Similarly, auditory illusions like 'Yanny' or 'Laurel' demonstrate how our expectations shape what we hear. The brain engages in a constant competition between different networks to determine perception, often resulting in a winner-take-all situation. The brain's ability to make assumptions and impose interpretations helps us navigate the noisy and ambiguous world, even though these assumptions can sometimes lead to misinterpretations or illusions.
The Battle of Interpretations
The necker cube illusion reveals the ongoing competition within the brain to determine perception. When faced with equa-probable interpretations, the brain switches back and forth between them, as different networks vie for dominance. However, our brain tends to stick with one interpretation if the possibilities are not equally probable. This reflects the brain's drive to impose a single interpretation and eliminate ambiguity, as it constantly tries to make sense of the world based on prior experiences and assumptions. While our perceptions may feel conscious and controlled, they are often influenced by random processes and the brain's internal competitions.
The Role of Expectations in Perception
Expectations play a crucial role in shaping our perception. The brain combines incoming sensory data with top-down information based on our prior experiences and assumptions. This combination determines what we perceive in the world. For example, the brain's ability to perceive colors consistently under different lighting conditions is due to the process of color constancy. Our brains rely on a multitude of cues to estimate background illumination and accurately perceive the color of objects. Our brains actively interpret information, making assumptions about lighting, background, and other contextual factors to construct our perception of the world.
Perception as Interpretation
Ultimately, our perception of the world is a process of interpretation rather than a direct reflection of reality. Our brains actively fill in the gaps and make assumptions based on limited sensory data. This active interpretation is necessary because our brains have to make quick decisions about how to navigate and interact with the world. While our brains can sometimes make mistakes or misinterpretations, this interpretive process is essential for our survival and functioning. Understanding the role of assumptions and interpretation in perception allows us to appreciate the power and flexibility of our brains in making sense of the world.
Why can you hear some sounds two different ways, depending on which word you’re looking at? Why do electrical outlets sometimes look like a face? How can you have rich visual experience with your eyes closed? Are some crosswalk buttons fake? Why are some pictures interpretable only once you’ve been told what to look for? And although brains are often celebrated for their parallel processing, what should they really be celebrated for? Tune in to learn what happens when the raw facts of the world collide with your expectations.
