Inner speech

Area of Science:

• Cognitive Science
• Neuroscience
• Philosophy of Mind

Background:

• Inner speech, also known as verbal thought, is a fundamental aspect of human consciousness.
• It plays crucial roles in abstract thinking, metacognition, memory, and executive functions.
• Its neural underpinnings and cognitive functions are increasingly understood.

Purpose of the Study:

• To explore the multifaceted roles of inner speech in cognition.
• To investigate the relationship between inner speech and auditory verbal hallucinations (AVHs) in schizophrenia.
• To introduce novel AI-driven methods for decoding inner speech.

Main Methods:

• Review of existing cognitive and neuroscientific research on inner speech.
• Analysis of the proposed link between inner speech and AVHs.
• Description of recent advancements in artificial intelligence for translating neural and neuromuscular signals of inner speech.

Main Results:

• Inner speech is vital for higher-order cognitive processes.
• A common hypothesis suggests AVHs arise from misattributing self-generated inner speech to external sources.
• AI can translate neural signatures of inner speech into audible speech.

Conclusions:

• Inner speech is a complex cognitive phenomenon with significant implications for understanding thought and consciousness.
• The AI-driven translation of inner speech signals offers potential for new therapeutic interventions.
• Further research is needed to fully elucidate the mechanisms and applications of inner speech decoding.
