A top-down analysis usually starts by reviewing a project and its functional areas‚ as a whole‚ without much detailed information.

Evaluate the evidence that visual perception involves bottom-up and top-down processing. The perceptual system is comprised of a of a diverse range of senses including visual‚ auditory‚ olfactory and tactition; the perceptual system is part of the nervous system‚ which contains millions of nerve cells called receptors that sense and respond to a plethora of sensory stimuli including light‚ sound and temperature. The act of perceiving rather than merely sensing enables us to analyse and make sense

Bottom-up processing is the analysis that begins with the sense receptors and works up to the brain’s integration of sensory information. It describes the work of sensory receptors that change stimuli into neural messages that most usually reaches the brain. Sensation is the process by which our sensory receptors and nervous system receives stimulus energies from our environment. Bottom-up processing is akin to sensation. An example of bottom up processing occurs in vision. Bottom-up processing
