Sensation: 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: sensory analysis that begins at the entry level, with information flowing from the sensory receptors to the brain. Retina is the transduction organ for the eye. Perception: top-down mental process of organizing and interpreting sensory input from experience and expectations. Top-down processing is info processing guided by high-level mental processes. as when we construct perceptions by filtering information through our experience and expectations. Context modifies how you perceive the information. Most of what we perceive is top down. Receive sensory stimulation, often using specialized receptor cells. Deliver the neural information to our brain. Environmental energy neural energy brain. Transduction: conversion of one form of energy into another.
