The Perception Process

The perceptual process is a sequence of steps that begins with stimuli in the environment and ends with our interpretation of those stimuli. This process is typically unconscious and happens hundreds of thousands of times a day. An unconscious process is simply one that happens without awareness or intention.

When we step out into a chilly night, our brain does not need to be told "cold" because the stimuli trigger the processes and categories automatically.
