Summary
Speech perception, including self-speech, is an intrinsic process, not just external input processing. This view equates normal speech perception with verbal hallucinations, highlighting attention
Area of Science:
- Cognitive Neuroscience
- Psychology of Perception
Background:
- Speech perception is traditionally viewed as processing external auditory input.
- This study proposes an alternative intrinsic model of speech perception.
Observation:
- Normal speech perception and verbal hallucinations share fundamental mechanisms.
- Auditory and proprioceptive feedback from speech articulation normally constrain perception.
Findings:
- Verbal hallucinations may arise when these constraints are disrupted.
- Perceptual qualities of hallucinations can originate from attention alone.
- Subvocal speech may contribute to the maintenance of verbal hallucinations.
Implications:
- This research reframes understanding of speech perception and auditory hallucinations.
- It suggests novel therapeutic targets for conditions involving hallucinations.
