Subconscious Brain Processes Improve Decision Making

Conducted by Carnegie Mellon University, a new scientific study has found that people make better decisions about buying new cars after they have been distracted by an unrelated task.

What's the Latest Development?


A new scientific study suggests that getting distracted mid-thought helps us to make better decisions later on. Conducted by Carnegie Mellon University, the study found that people made better decisions about buying new cars after they had been distracted by an unrelated task. "But did this effect occur because the distraction period provided an opportunity for the brain to take a break from decision-making and then return to the problem with a fresh look? Or alternatively, does the brain continue to unconsciously process decision information during this distraction period?"

What's the Big Idea?

By creating images of the participants' brains during the study, researchers concluded that the brain subconsciously processes information, helping us to make better decisions. "When the participants were initially learning information about the cars and other items, the neuroimaging results showed activation in the visual and prefrontal cortices, regions that are known to be responsible for learning and decision-making. Additionally, during the distractor task, both the visual and prefrontal cortices continued to be active—or reactivated—even though the brain was consciously focused on number memorization."

Is this why time speeds up as we age?

We take fewer mental pictures per second.

Mind & Brain
  • Recent memories run in our brains like sped-up old movies.
  • In childhood, we capture images in our memory much more quickly.
  • The complexities of grownup neural pathways are no match for the direct routes of young brains.

Trauma in childhood leads to empathy in adulthood

It's not just a case of "what doesn't kill you makes you stronger."

Mind & Brain

  • A new study suggests children who endure trauma grow up to be adults with more empathy than others.
  • The effect is not universal, however. Only one kind of empathy was greatly effected.
  • The study may lead to further investigations into how people cope with trauma and lead to new ways to help victims bounce back.

Why are so many objects in space shaped like discs?

It's one of the most consistent patterns in the unviverse. What causes it?

Videos
  • Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
  • Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
  • Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
