Summary

Off-Target Verbosity (OTV) in speech remained stable over 15 months in older adults. Life changes and lower verbal fluency correlated with increased OTV, influenced by age-related factors.

Area of Science:

  • Gerontology
  • Psycholinguistics
  • Cognitive Science

Background:

  • Off-Target Verbosity (OTV) is a speech characteristic observed in older adults.
  • Understanding the stability and correlates of OTV is crucial for assessing cognitive and psychosocial health in aging populations.

Purpose of the Study:

  • To conduct a follow-up examination of speech patterns, specifically Off-Target Verbosity (OTV), in individuals aged 65 and over.
  • To assess the stability of OTV over a 15-month period and re-evaluate its cognitive and psychosocial correlates.

Main Methods:

  • Longitudinal study involving 175 subjects aged 65+.
  • Speech samples were evaluated for Off-Target Verbosity (OTV) at two time points, 15 months apart.
  • Cognitive function, verbal fluency, and psychosocial variables (life changes) were assessed.

Main Results:

  • Off-Target Verbosity (OTV) demonstrated significant stability across the 15-month study duration.
  • A consistent pattern of relationships was observed between age, cognitive function, psychosocial variables, and OTV scores.
  • Increased OTV was associated with more frequent, undesirable life changes and lower verbal fluency.
  • Age-related inhibition and psychosocial functioning were identified as factors contributing to the association between age and OTV.

Conclusions:

  • Off-Target Verbosity (OTV) is a stable speech characteristic in older adults.
  • Cognitive factors (verbal fluency) and psychosocial factors (life changes) are significant correlates of OTV.
  • The findings support a conceptual model linking age, cognitive function, psychosocial well-being, and OTV in the aging process.
