Document Summary
Perception does not just happen, but it is the end result of complex behind the scenes processes, many of which are not available to your awareness. The perceptual process, is a sequence of processes that work together to determine our experience of an reaction to stimuli in the environment. The perceptual process is divided into four categories: stimulus, electricity, experience, and action, and knowledge. The stimulus exists both out there, in the environment, and within the person"s body. Environmental stimulus is all of the things in our environment that we can potentially perceive. The attended stimulus changes from moment to moment. One of the central principles of perception is that everything we perceive is based on electrical signals in our nervous system. These electrical signals are created in the receptors, which transform energy from the environment into electrical signals in the nervous system a process called transduction. Is the transformation of one form of energy into another form of energy.
