Meaning that Gibson’s theory argues that perception functions as a straight line, we experience new stimuli through our sensations and then directly analyze their meaning. Gibson looked at perception as more of a ‘what you see is what you get’ kind of situation. Gibson (1966) argued that no learning was required to perceive new stimuli.
These impulses are passed into the brain where they trigger further responses along the visual pathways until they arrive at the visual cortex for final processing.īottom-up processing states that we begin to perceive new stimuli through the process of sensation and the use of our schemas is not required.This information is replayed to the retina where the process of transduction into the electrical impulses begin.We start with an analysis of sensory inputs such as patterns of light.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. Perception is unique to each individual as we are interpreting these sensations based on our individual schemas that are constructed from previous knowledge, experiences, and expectations (Jandt, 2020).īottom-up processing starts with minute sensory details that are then used to construct larger ideas or perceptions about one’s external environment. Perception is how our brains choose, organize, and interpret these sensations. Bottom-up processing is the process of ‘sensation’, whereby the input of sensory information from the external environment is received by our sensory receptors. Sensation is the input of sensory information from our external environment that is received by our sensory receptors. Whereas in bottom-up processing, no learning is required, and perceptions are solely based on new stimuli from one’s current external environment, meaning that the driving force of perception in bottom-up processing is the stimulus that is currently being experienced within one’s external environment (Gibson, 1972).īottom-up processing is the process of ‘sensation’ and top-down is the process of ‘perception’. In top-down processing we know that previous knowledge, experience, and expectations are essential in creating perceptions about new stimuli, so the driving force in top-down perception is one’s previous knowledge, experience, and expectations (Gregory, 1974).
Top-down processing is the interpretation of incoming information based on prior knowledge, experiences, and expectations. Top-down processing is the interpretation of incoming information based on prior knowledge, experiences, and expectations (Gregory, 1970)īottom-up processing begins with the retrieval of sensory information from our external environment to build perceptions based on the current input of sensory information. The bottom-up process involves information traveling 'up' from the stimuli, via the senses, to the brain which then interprets it, relatively passively.īottom-up processing is also known as data-driven processing, because the processing of information begins with environmental stimuli, and perceptions are built from sensory input.īottom-up processing begins with the retrieval of sensory information from our external environment to build perceptions based on the current input of sensory information (Gibson, 1966).
