Summary
People with schizophrenia show impaired auditory self-recognition, having difficulty identifying their own voice and misattributing others' voices. This study highlights altered self-processing in schizophrenia beyond the visual domain.
Area of Science:
- Neuroscience
- Psychiatry
- Cognitive Psychology
Background:
- Self-recognition is crucial for self-identity.
- Visual self-recognition deficits are known in schizophrenia.
- Auditory self-recognition in schizophrenia remains understudied.
Purpose of the Study:
- Investigate auditory self-recognition in schizophrenia.
- Explore unimodal and multisensory processing of self-voice.
- Identify potential psychopathological roots in schizophrenia.
Main Methods:
- Unimodal and multisensory tasks assessing auditory self-recognition.
- Involved 46 adults with schizophrenia and 32 healthy controls.
- Compared perceptual sensitivity and decision criteria for self-voice.
Main Results:
- Schizophrenia patients exhibited lower perceptual sensitivity to self-voice.
- Participants with schizophrenia showed stricter self-voice decision criteria.
- Schizophrenia group misattributed others' voices when presented with own voice stimuli.
Conclusions:
- Auditory self-recognition is altered in individuals with schizophrenia.
- Deficits extend beyond visual self-processing.
- Findings contribute to understanding self-processing alterations in schizophrenia.

Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

01:29Psychological and Sociocultural Causes of Schizophrenia
327
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...
