Document Summary

The detectors include the eyes, ears, skin receptors, and receptors in the nose and mouth. The perceptual process- a sequence of processes that work together to determine our experience of and reaction to stimuli in the environment. Process is divided into 4 categories: stimulus- what is out there in the environment, what we actually pay attention to, what stimulates our receptors. The stimulus can be in environment or within a person"s body. Environmental stimuli- all things in our environment that we can potentially perceive. Attended stimuli- things that are particularly focused on by the observer; changes from moment to moment. The attended stimulus is transformed into an image on the retina. The next step involves transforming the image into electricity: electricity- electrical signals created by the receptors, which turn energy from environment into electrical signals in the nervous system. Everything we perceive is based on electrical signals in our nervous system.
