Area of Science:

  • Occupational Health
  • Gerontology
  • Cognitive Psychology

Background:

  • Aging workforce presents unique challenges in maintaining performance efficiency.
  • Understanding age-related cognitive and motor changes is crucial for workplace adaptation.
  • Municipal workers represent a diverse occupational group with varying job demands.

Purpose of the Study:

  • To compare the performance efficiency of aging municipal workers across different job categories.
  • To assess changes in visual search, short-term memory, and fine motor skills over a four-year period.
  • To investigate the influence of work type on cognitive and motor performance decline in older adults.

Main Methods:

  • Longitudinal study tracking municipal workers from approximately 51 years of age.
  • Assessment of cognitive functions including visual search and short-term memory.
  • Evaluation of fine motor performance and overall work efficiency.
  • Categorization of workers into mental, physical, and mixed work groups.

Main Results:

  • Workers in mental work exhibited superior mental capacity compared to those in physical or mixed roles.
  • No significant performance difference was observed between physical and mixed work groups.
  • Complex short-term memory declined by 6-7% across all groups over four years.
  • Fine motor speed decreased by 2-7% in physical and mental work groups.

Conclusions:

  • The mental capacity of older workers is significantly influenced by the cognitive demands inherent in their job tasks.
  • A performance decline of 2-7% in cognitive and motor skills is evident between the ages of 51 and 55.
  • Workplace interventions may be necessary to mitigate age-related performance decrements, particularly in physically or mentally demanding roles.
