bottom-up processing
analysis begins withe the sensory receptors and works up to the brain’s integration of sensory information
Bottom-up processing refers to the mental processing that starts with the sensory information retrieved from the environment, which then moves upwards to become more complex processes in the brain. This processing method is also known as data-driven processing, as it entirely relies on the data and information collected through our senses to create perceptions, understandings, and reactions.
In simpler terms, bottom-up processing is the analysis of sensory information that occurs first, before involving memory, expectation, or any cognitive processes. For example, when you hear a sound, your brain automatically processes the auditory information to identify the source before determining whether it is important or not.
Bottom-up processing is essential in the development of attention span, perception, and general knowledge. Infants and young children rely heavily on this process to understand the world around them. They eventually start to associate new sensory information with previous experiences, which leads to the development of cognitive processing and memory.
Overall, bottom-up processing is a fundamental mechanism in how we perceive and process information through our senses. It is an essential first step in how we learn about and understand the environment around us.
