Final answer:
Circadian rhythms are not changes in sensory processing due to aging, but are regular biological and behavioral changes that follow a roughly 24-hour cycle, controlled by a biological clock within the brain.
Step-by-step explanation:
The statement "Circadian rhythms are the changes that occur in our ability to process sensory information as we age" is false. Circadian rhythms are the regular changes in biology or behavior that occur in a 24-hour cycle. These rhythms are controlled by a biological clock located in the brain.
The clock influences many physiological processes and behaviors such as sleep-wake patterns, body temperature, blood pressure, and even hormone secretion. Therefore, circadian rhythms are more about the internal perception of the daily cycle of light and dark, and not specifically about changes in sensory processing as we age.
