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.
