Silent reading of direct versus indirect speech activates voice-selective areas in the auditory cortex [PDF]
In human communication, direct speech (e.g., Mary said: “I'm hungry”) is perceived to be more vivid than indirect speech (e.g., Mary said [that] she was hungry). However, for silent reading, the representational consequences of this distinction are still
