Document Summary
The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. Bottom-up process by which the physical sensory system receives and represents stimuli at the very basic level of sensory receptors and works up. Bottom up processing is analysis that begins with the sensory receptors and works up to the brain"s integration of sensory information. Ex: enables our sensory systems to detect the lines, angles, and colors that form the flower and leaves. The process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events. Top-down mental process of organizing and interpreting sensory input from experience and expectations. Top down processing is information processing guided by high level mental processes, as when we construct perceptions by filtering information through our experiences and expectations. Ex: enables us to interpret what our senses detect. Receive sensory stimulation, often using specialized receptor cells. Deliver the neural information to our brain.
