Summary

Sensory perception of oral stimuli, like taste and temperature, remains accurate with age. However, the ability to perceive localized tongue pressure significantly declines in older adults.

Area of Science:

  • Sensory neuroscience
  • Gerontology
  • Oral sensory perception

Background:

  • Oral sensory perception is crucial for quality of life, influencing eating and drinking.
  • Understanding how age affects different oral sensory modalities is important for health and well-being.

Purpose of the Study:

  • To assess how healthy older adults perceive oral sensory intensity compared to younger adults.
  • To investigate the impact of aging on the perception of various oral stimuli, including taste, temperature, texture, and pressure.

Main Methods:

  • Cross-modal matching was used to quantify perceived intensity of five oral stimuli (sweet, salty, thermal, viscous, pressure) in healthy men and women aged 25-93.
  • Measures included response size, quality, repeatability, and linearity with stimulus strength.
  • Statistical analyses examined differences across stimulus types and the effect of age.

Main Results:

  • Different oral stimuli elicited varying response sizes and rates of intensity increase, but judgment quality and repeatability were consistent.
  • Age did not significantly affect perception of taste, temperature, or texture.
  • Perception of localized lingual pressure significantly declined with age, except for median size.

Conclusions:

  • Oral sensory perception of taste, temperature, and texture is well-maintained into older age.
  • Aging specifically impairs the perception of localized lingual pressure, while other oral sensory judgments remain accurate.
  • These findings highlight a selective decline in sensory function with age, impacting specific oral sensations.
