How does aging affect sensory perception?

Aging has a significant impact on sensory perception, and option C accurately reflects this by noting that it can lead to decreased sensitivity and changes in how sensory information is processed. As people age, various sensory systems—such as vision, hearing, taste, and touch—often begin to decline. For instance, visual acuity may weaken due to changes in the lenses of the eyes, and auditory sensitivity may decrease, making it harder for individuals to hear high-frequency sounds.

In addition to diminished sensitivity, aging can also affect the way the brain processes sensory information. This might result in slower reaction times, increased difficulty in filtering out irrelevant stimuli, and altered perception of sensory inputs. These changes can impact daily life and the overall experience of the environment.

Other possible options suggest that aging universally enhances sensory acuity, increases sensitivity to stimuli, or has no effect at all. However, research does not support these views, which underscores why option C is the most accurate representation of the effects of aging on sensory perception.
