Hypothesis
Is there empirical evidence to support the anecdotal reports of speech perception deficits in individuals with Parkinson's disease?
Conclusion
The review suggests that individuals with Parkinson's disease may have deficits in perceiving their own speech loudness and emotional prosody.
Supporting Evidence
- Studies indicate that individuals with Parkinson's disease often overestimate their speech loudness.
- Research shows deficits in recognizing emotional prosody in speech among Parkinson's patients.
- Some studies suggest that cognitive impairments may contribute to these perceptual deficits.
Takeaway
People with Parkinson's disease might not hear their own voice correctly, thinking they are speaking louder than they actually are, and they also struggle to understand emotions in speech.
Methodology
The paper reviews various studies on speech perception in individuals with Parkinson's disease, focusing on loudness and emotional prosody.
Limitations
Discrepancies in findings may be due to differences in methodologies and the nature of tasks involved.
