With advancing age, which of the following normal physiological changes in sensory function occurs?

1. Decreased sensitivity to glare
2. Increased number of taste buds
3. Difficulty discriminating vowel sounds
4. Decreased sensitivity to pain

ANSWER

ANS: 4
Older adults experience tactile changes, including declining sensitivity to pain, pressure, and temperature. Older adults have an increased sensitivity to glare. Older adults have a decreased number of taste buds. Older adults have difficulty discriminating the consonants (z, t, f, g) and high-frequency sounds (s, sh, ph, k).
