Document Summary
The stimulus impinges causing to change their behavior. This change is related to the stimulus and is often interpreted as internal representation of the stimulus: receptor processes (step 3, sensory receptors are specialized cells that respond to environmental energy. The transduction refers to the translation of environmental energy into electrical energy. Electrical energy in the receptors is in the form of brief impulses (nerve impulses). Rod and cone receptors line the back of the eye. They change light energy into electric energy and influence what we perceive: neural processing (step 4, changes that occur as signals are transmitted through the maze of neurons. In this process, some parts of the signal may be amplified and others may be attenuated. Each sense sends signals to different areas of the brain: behavioural responses (step 5 - 7, electrical signals are transformed into conscious experience.
