Document Summary
Stimulus: what is out there in the environment, what we actually play attention to, and what stimulates our receptors. Electricity: the electrical signals that are created by the receptors and transmitted to the brain. Experience and action: our goal to perceive, recognize, and react to the stimuli. Knowledge: knowledge we bring to the perceptual situation. Exists both out in the world and in our body. Environmental stimulus is all of the things in our environment that we can potentially perceive. When ones attention is captured by something, it becomes the attended stimulus, which changes from moment to moment. The image that is ones center of attention is transferred to an image on your retina the stimulus on the receptors. Transduction is the transformation of one form of energy into another form of energy it occurs in the nervous system when energy in the environment is transformed into electrical energy.
