A psychologist randomly divides patients experiencing social anxiety into three groups, each of which receives a different treatment believed to reduce social anxiety. A research assistant, who knows nothing about the study, measures each patient's level of social anxiety using a standard questionnaire once before and once after their treatment. The psychologist analyzes the data afterwards, and finds that group 3 is the only group who showed a reduction in their social anxiety scores, from pre-treatment to post-treatment.

When our senses are exposed to a constant stimulus for a period of time, they gradually stop sensing that stimulus (this effect doesn't last long and is called sensory adaptation). Why does this happen (explain the mechanism) and how might it be beneficial or adaptive to our functioning?
Sensory adaptation occurs because sensory neurons are fatigued. If stimulus is continuously presented, system is less responsive, and it can ignore unimportant stimuli and be ready for something important.
