![]() ![]() One simple example of bottom up processing is when you are walking to a friend’s bathroom in the middle of the night. Gibson argued that the idea of affordances were crucial to the idea of bottom-up processing.He theorized that when we were looking at an item, we observed its particular affordances. ![]() For the simplest example, a chair is a construction of wood, however it ‘affords’ us the opportunity to sit in it. While Gibson was developing the theory of bottom-up processing, he coined the term “affordances.” Everything we see has a number of affordances, or different opportunities to interact with the item.Īn affordance is a thing that offer something to the perceiver more than what it specifically is. In fact, he is one of the founders of ecological psychology. ![]() He is arguing that we are solely using nature to perceive the world and analyze what we are seeing. nurture debate, it is clear that Gibson takes the side of nature. When you apply this idea to the nature vs. Reductionism is the idea that we break down big ideas into their most basic parts.(This is the opposite of holism, which looks at the “big picture” ideas first.) As the visual stimuli moves from the retinas in the eyes to the visual cortex in the brain, we begin to move deeper and deeper into an analysis of what we are seeing. The process from looking at stimuli to analyzing it is a direct line. Why? Gibson theorized that no learning is necessary to perceive stimuli. The theory of bottom-up processing sounds easy enough, but Gibson’s theory on this process is still grounds for debate in the world of psychology. Gibson developed the theory of bottom-up processing, and his work has significantly impacted the world of psychology, behaviorism, and neurology. I’m going to focus specifically on the bottom-up approach to processing and how we process the stimuli that is around us. We apply our knowledge and expectations to create a backdrop for our world as we perceive it, and then begin to focus on the smaller details using sensation. The other is a “top down process” that starts with memories, expectations, and motivations. One argues that sensory and perception are the same, and that we process stimuli first and analyze it later. We call these theories “bottom up” and “top down” processing. Some argue that they are exactly the same. Some psychologists argue that sensation and perception are two different processes. But before you could recognize the computer, you took in the individual parts of the computer: the shape of the machine, the light emanating from the screen, each of the keys on the keyboard, etc. Right now, you see a computer screen and some animations. Uses for Bottom Up Processing in Everyday Life What is Bottom Up Processing?īottom-up processing is the idea that we begin to perceive items with sensation, as opposed to our conceptual ideas. This process is also known as “data-driven processing,” because it is just that: driven by the data that we collect with our senses. ![]()
