Answer:
Sensory adaptation
Step-by-step explanation:
In psychology, the term sensory adaptation refers to the process by which the body sensory receptors adapt to certain stimuli after being constantly exposed to them and therefore it makes them less noticeable for the person. In other words, the person is exposed to a particular stimulus and after some time of exposure, the person stops noticing said stimulus.
In this example, Thad turns on the air conditioner and starts watching television. One hour later Sean comes and wonders how Thad can hear the tv considering the loud noise the air conditioner makes, Thad doesn't even notice the sound. We can see that Thad was exposed to the sound of the air conditioner for an hour and he stopped noticing it at all after this time. Therefore, this example would be a good example of sensory adaptation.
