Excitement, fatigue, and anxiety can all be detected from someone's blinks, according to p

sychologist John Stern (21) Washington University in St. Louis. Stern specialized in the study on these tiny twitches, using them as sensitive (22) of how the brain works. "I use blinks as a psychological measure to make (23) about thinking because I have very little (24) in what you tell me about what you are thinking." He says. "If I ask you the question, 'what does the phrase a rolling stone gathers no moss mean？' you can't tell me (25) you've started looking for the answer. But I can, by watching your eyes."
