How to separate learning myths from reality

The left/right brain hypothesis

The theory that most people are either dominantly analytical (and left-brained) or creative (and right-brained) is false.

The two hemispheres of the brain are linked and communicate extensively together; they do not work in isolation. 

Recent studies suggest that engaging all the senses in a variety of ways (for instance, audiovisual and tactile) can help employees retain new content.

Styles of learning

The concept of learning styles--such as visual versus verbal or active versus reflective--is commonplace, but it turns out that there is little evidence to ...

Right-brained or left-brained

Research doesn’t strongly support this concept of the lateral brain--or that people have a dominant side of the brain that dictates how we learn.  

Even in simple actions, both hemispheres of the brain are engaged. 

"Exercises" that will make you smarter

"One minute playing Mozart will make your baby a genius, the next crosswords will fend off your mental decline"... The research behind these claims is weak. 

Learning methods are not so much based upon how the brain is structured, but based upon our experiences. Our experiences do affect brain development. The wiring of the brain depends upon the experiences we have.

Re-reading and highlighting

Both of these study strategies are relatively ineffective. Passively reading the same text over and over again won’t do much for recall unless it’s spaced out over time. 

Different learning styles

Systematic studies of learning styles have consistently found no evidence or very weak evidence to support the idea that matching the material to a student’s learning style is more effective.

Right or left-brained

There is no conclusive evidence that people preferentially use the left or right hemisphere.

Certain functions are processed more by one region of the brain than others, and this is known as lateralization. But we all use our entire brain equally.

Left-brained or right-brained

People used to speak of being left or right-brain dominant (where the left brain is more logical and algorithmic, and the right brain more artistic and intuitive).

However, both hemispheres of your brain are involved in all of the complex work you do. The most effective thinkers are the ones who learn to rely on both their intuitive judgments as well as their reasoning.

Emotions and rational thinking

The theory goes that emotions reflect a more primitive form of thinking and that good thinking is only logical.

However, when faced with risky decisions, it is possible to talk yourself into almost anything. But, even a little anxiety in that situation can provide information too valuable to ignore.
