Adaptation level theory

Baxter Neal Helson's adaptation level theory is a foundational concept in the field of perception. It states that our perception of a stimulus is not simply a function of the physical properties of the stimulus itself, but also of our past experiences with similar stimuli. In other words, our perception of a stimulus is adapted to our expectations.

For example, if we are in a dark room and a light is turned on, we will perceive the light as being brighter than if we were in a well-lit room and the same light was turned on. This is because our adaptation level for brightness is lower in the dark room than in the well-lit room. Our perception of the light is adapted to our expectations, which are based on our past experiences.

Adaptation level theory has important implications for our understanding of perception. It tells us that our perception of the world is not simply a passive recording of sensory information, but rather an active process that is influenced by our past experiences and expectations. This understanding has important implications for fields such as marketing, design, and education.
