When light enters the eye, it is converted from light energy to electrical signals to chemical signals that the brain can understand and interpret. The process of the information changing from visual signals to electric signals to chemical signals is called:
  1. Signal detection
  2. Translation
  3. Sensory reception
  4. Transduction
Explanation
Answer: D - The process of information changing from light energy to electrical signals to chemicals signals the brain can understand is a process called transduction.
Sensory information (whether light waves for the eye or sound waves for the ears) cannot be interpreted as they are. Thus, our body has sense organs that help to convert sensory information into information our brain can interpret. This process of converting sensory information into something our brain can interpret is referred to as transduction.
