Eyes Are the Windows to the Brain
Who a person is relates to how they move their eyes, says cognitive scientist Dr. Aaron Risko. New eye-tracking technology is giving researchers more insight into how someone thinks.
What's the Latest Development?
Cognitive science has updated the old adage that the eyes are the windows to the soul. New eye-tracking technology in the form of video cameras, which record every miniscule movement of the eye, are giving scientists important data on eye movement patterns—where we look, and for how long—revealing important information about how we read, how we learn and even what kind of people we are. Now the eyes are the window to the brain and scientists are exploring how we learn from text and images, including those viewed onscreen.
What's the Big Idea?
Who is using the new data and how? Advertisers are better informed about where to place an ad so that you will look at it. Ads that move, for example, are harder for people to ignore. On the opposite side, scientists are using the data to eliminate distraction and improve focus. Psychologists Elizabeth Grant and Michael Spivey realized through experiments that guiding attention can guide thought, so if learners can be directed toward important information, they are more likely to solve related problems.

A NASA astronomer explains how astronauts dispose of their, uh, dark matter.
- When nature calls in micro-gravity, astronauts must answer. Space agencies have developed suction-based toilets – with a camera built in to ensure all the waste is contained before "flushing".
- Yes, there have been floaters in space. The early days of space exploration were a learning curve!
- Amazingly, you don't need gravity to digest food. Peristalsis, the process by which your throat and intestines squeeze themselves, actually moves food and water through your digestive system without gravity at all.
She met mere mortals with and without the Vatican's approval.
- For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
- These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
- Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.
A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
