Older adults show greater timing disruptions when attention is divided during breaks. Performance is impacted by age-related differences in attention sharing and preparation for timing tasks.

Area of Science:

  • Cognitive psychology
  • Neuroscience of aging

Background:

  • Timing accuracy declines with age.
  • Interruption effects on temporal judgment are not fully understood.

Purpose of the Study:

  • To investigate age-related differences in time production during interrupted intervals.
  • To examine the impact of attention sharing on timing performance in older adults.

Main Methods:

  • Participants performed a time production task with a signaled break.
  • Reaction time to the break signal was measured.
  • Intervals preceding the break varied in duration.

Main Results:

  • Produced intervals lengthened with increasing delay before interruption.
  • This lengthening effect was more pronounced in older adults.

  • Older adults were slower to react to the break signal but benefited more from longer pre-break intervals.

    • Conclusions:

    • Older adults' timing performance is more susceptible to attention sharing demands.
    • Age-related deficits in attention and preparation influence timing accuracy during interruptions.
