Preattentive Processing

Preattentive Processing is a term that refers to the body’s processing of sensory information (ambient temperature, light levels, etc.) that occurs before the conscious mind starts to pay attention to any specific objects in its vicinity. An example of this is that when a person walks out of their home, the first thing that is noticed is the temperature and whether it is day or night, then the mind starts to process the events that are occurring in the area.
