Myth: We only use 10 per cent of our brain.
Reality: Brain imaging suggests that all parts of the brain are active.

Myth: We have multiple "types" of intelligence, from interpersonal to logical, with corresponding IQs.
Reality: Neuroscientific research distinguishes cognitive processes in the brain, but these do not correspond to different intelligences. A more accepted view is that each person has a general intelligence, and their various cognitive abilities are correlated with how high this is.

Myth: The left side of the brain deals with rational thinking and the right side is emotional. Most people are dominated by one half.
Reality: Each side has different functions, but there is little evidence that these reflect thinking styles.

Myth: Drinking plenty of water is important for brain function.
Reality: Thirst kicks in long before lack of water affects brain function. Drinking water in class may improve performance because it creates mini-breaks that help with focus.
Myth: Listening to classical music makes you smart.
Reality: Music helps you learn, but so do other activities you enjoy. Music training, however, can have measurable benefits. Children performed better in IQ tests after a year of music lessons. But it is wrong to assume that music can improve your overall intelligence, or musicians should be all-round geniuses. Music lessons work by improving executive function allowing students to utilise their intelligence more effectively.
Myth: Bilingual education leads to confusion and delayed development, due to conflict between the two language systems.
Reality: The opposite is true. Switching between languages improves impulse control and the ability to concentrate.


Researchers say a stronger focus on exercise could help with cognition and learning. In a study of brain electrical activity, it was found that fitter students showed signals that reflected increased concentration and ability to ignore distractions.
