Answer:
Sensory adaptation
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 <u>Thad was exposed to the sound of the air conditioner for an hour and he stopped noticing it at all after this time. </u>Therefore, this example would be a good example of sensory adaptation.

Negative externality: Arises when not all the costs of a negative effects are assumed. In these cases, a social cost is generated, since it is the whole society that suffers the consequences of its actions. And the market price does not collect this cost.
Positive externality: Arises from a positive effect that is not reported as a benefit. An example of positive externality that we can mention is scientific research, from which society in general benefits. In these cases, market place do not reflect the real benefits.
