Top Down Bottom Up Processing
Perception involves both bottom-up and top-down processing. One way to think of this concept is that sensation is a physical process (bottom-up processing), whereas perception is psychological (top-down processing). • Bottom-up processing refers to the fact that perceptions are built from sensory input. These processes are called top-down and bottom-up.
Top-Down Processing. Top-down processing is defined as the development of pattern recognition through the use of contextual information. For instance, you are presented with a paragraph written with difficult handwriting. Bottom-up processing refers to using the incoming input as the basis for understanding the message. Comprehension begins with the received data that is analyzed as successive levels of organization - sounds, words clauses, sentences, texts until meaning is derived. Comprehension is viewed as a process of decoding.
Top-down processing presumes that something similar to a boss-employee relationship exists between the prefrontal cortex and the limbic system: namely, the thinking centers of the brain can activate cognitive controls adjusting the feeling centers of the brain.. Following this logic, enhanced cognitive regulation would enable a person to alter the relevance of current environmental "stimuli ... Unlike top-down processing, bottom-up processing is purely data-driven and requires no previous knowledge or learning. Bottom-up processing takes place as it happens. For example, if you see an image of an individual letter on your screen, your eyes transmit the information to your brain, and your brain puts all of this information together.
Top-down and bottom-up processing are processes that usually work together, so it's not normally this or that happening at one time. Key Takeaways: Top-Down Processing Top-down processing is the process of using context or general knowledge to understand what we perceive. Richard Gregory introduced the concept of top-down processing in 1970. We use top-down processing to quickly understand the sensory input we take in when we interact with different environments.
Bottom-up processing is the process of 'sensation' and top-down is the process of 'perception'. Sensation is the input of sensory information from our external environment that is received by our sensory receptors. Top-down processing occurs when we form perceptions based on what we already know, beginning with generalities, then moving to specific details.

Processing is carried out in one direction from the retina to the visual cortex, with each successive stage in the visual pathway carrying out ever more complex analysis of the input.
