Document Summary
6. 1 basic principles of sensation and perception. Sensation the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. Perception the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events. In our everyday experiences, sensation and perception blend into one continuous process. Bottom-up processing analysis that begins with the sensory receptors and works up to the brain"s integration of sensory information. Top-down processing information processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expectations. Our sensory systems convert one form of energy into another. All our senses: receive sensory stimulation, often using specialized receptor cells, transform that stimulation into neural impulses, deliver the neural information to your brain. Transduction conversion of one form of energy into another. In sensation, the transforming of stimulus energies, such as sights, sounds, and smells, into neural impulses our brain can interpret.
