Stimulus - what is in the environment and what we pay attention to. Exists out there in the environment and within the person"s body. Electricity - electrical signals that are created by receptors and transmitted to the brain. Experience and action - goal (perceive, recognize and react to stimuli) Knowledge - knowledge we bring to the perceptual situation. Environmental - e. g. trees, path, rustling noises, etc. Attended - e. g. attention captured by distinctive looking tree off to the right.
