People communicate constantly, and a great deal of that communication takes place outside of spoken or written words. This can include facial expressions, eye contact, tone of voice, touch, our overall appearance, and countless other subtle gestures such as nodding our head or waving our hands.
We each use all of these representational systems to various degrees and in different ways.
For example, one person might be mostly visual, moderately auditory, and slightly kinesthetic, while another person might be mostly kinesthetic, moderately visual, and slightly auditory—really, any combination is possible! It’s also important to note that smell and taste also play a role in how some people process information.
