Document Summary

Sensation: stimulus-detection process, process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment, provides the raw data about the world. Perception: the organizing and giving meaning to input, the process of organizing and interpreting sensory information enabling us to recognize meaningful objects and events. Sensory and perceptual processes bottom up and top down. Information comes in through our senses: our brains interpret this information, you look with your eyes, you. Bottom up: starts at sensory receptors and works up to higher level processing. Top down: constructs perceptions from sensory input by drawing on our experience and expectation. Motivation: letter and numbers associated with good and bad tasks. Adaptive value: frees sense from the unchanging to be more sensitive to changes in environment. Sensory and perceptual processes: vision: light energy enters our eyes, photoreceptors transduce light into electrical impulses.
