The electrophysiological signature of inner speech

点击翻译按钮获取中文摘要

This project aims to develop an objective neurophysiological marker that identifies when a person is talking silently to themselves in their head (inner speech), and what they are saying internally. Such a marker would be an important development in the field of cognitive science. It could reveal the fundamental nature of inner speech (whether inner speech is actually a special form of overt speech), and lead to ‘brain-computer interface’ technologies that can decipher inner speech and communicate it with the outside world.
