  • Scientists discover that individuals with more brain activity learn slower than those

  • with less brain activity. So stop thinking and learn! … wait what?!

  • Hi Everyone! Crystal here for DNews exploring the idea that over thinkers like me, may learn

  • new tasks more slowly and be less successful at those tasks than those who don’t analyze

  • and evaluate their every move.

  • Scientists have known for a while that cognitive control from the frontal cortex can have a

  • depressing effect on our ability to learn new tasks. This is probably because that brain

  • region is responsible for problem solving, planning and execution, and itstop down

  • regulation of our behavior can lead us to make things more complicated for ourselves

  • than they really are.

  • Children learn wayyy faster than adults because they are not subject to this cortical control.

  • They CAN’T over think because their judgy frontal cortex hasn’t been fully developed

  • yet! This is one reason why kids are more creative and frequently take risks that an

  • adult probably wouldn’t.

  • When humans are exposed to a new task almost our entire brain is active and desperately

  • trying to make sense and associations from the new input. As we get better at the task

  • andfigure it outthis global network activity gets pruned to only what we need

  • specifically for task performance (eg. motor and visual cortices). How quickly this specification

  • happens corresponds to howquicklywe learn the task.

  • Researchers at several universities, looked at this process across the whole brain and

  • recorded which regions maintained their connections and activity, and which ones didn’t. These

  • data were recorded as fMRI scans of whole brain as subjects learned a simple musical

  • computer game. The scientists were hoping to visualize the changes that happened as

  • people learned, but what they didn’t expect is that subject data would organize itself

  • into two categories: “fastlearners andslowlearners.

  • Those who learned the musical video game very quickly showed rapid drop off of global brain

  • activation. Theslowlearners maintained more global brain activity over the six week

  • trial and showed prolonged involvement of associative regions of the cortex. This lead

  • researchers to conclude thatover thinking” - by maintaining vigilance, monitoring errors,

  • and frequently making associative judgements - makes it more difficult for individuals

  • totransform a task from slow and challenging to fast and automatic”.

  • More studies are needed to truly understand this process but it very well could be that

  • analyzing your thinking about thinking about what you are trying to learn isn’t doing

  • you any favors and making it harder for you to be successful.

  • So get out of your own way, stop second-guessing and re-optimizing everything and just let

  • it happen!!

  • What do you think? What task are you making more difficult for yourself?
