As we dive deeper into understanding IS, we encounter the challenge of deciphering the individual differences in how people engage in inner speech. Additionally, researchers are focused on unraveling how the different forms of IS relate to their specific functions.
If you’re eager to explore more about this enchanting phenomenon and its implications for our minds, I highly recommend diving into the underlying research!
Many people report a form of internal language known as inner speech (IS). This review examines recent growth of research interest in the phenomenon, which has broadly supported a theoretical model in which IS is a functional language process that can confer benefits for cognition in a range of domains. A key insight to have emerged in recent years is that IS is an embodied experience characterized by varied subjective qualities, which can be usefully modeled in artificial systems and whose neural signals have the potential to be decoded through advancing brain–computer interface technologies. Challenges for future research include understanding individual differences in IS and mapping form to function across IS subtypes.
