Hypothesis

How do vocal responses to auditory feedback change with age?

Conclusion

The study found that vocal responses to pitch feedback increase until age 51-60 and then decrease for older adults.

Supporting Evidence

  • Response magnitudes increased with age until 51-60 years, then decreased.
  • Adults aged 51-60 were more sensitive to pitch feedback changes than younger adults.
  • The study included a diverse age range to assess changes in vocal pitch control.

Takeaway

As people get older, their voices respond differently to changes in pitch, peaking around age 51-60 before declining.

Methodology

Participants aged 19-75 were divided into five age groups and their vocal responses to pitch-shifted feedback were measured.

Limitations

The study did not include sex as a variable, which may affect vocal responses.

Participant Demographics

60 adults aged 19-75, 35 female and 25 male.
