That is they process information through their guts or with their feelings. People using this kinesthetic channel have to touch an object to assess it and understand it. Most people are using either the auditory or visual representational systems to process information most of the time. An important point to remember here is that the person with whom we are communicating uses all three representational systems to process information at one time or another. What we are concerned with is what is the primary channel being used when we are trying to communicate with that person.
Most people tend to favor one channel over another.
Some people use the visual channel most of the time. On the other hand, some people use the auditory channel most of the time. But do not forget that people switch channels from time to time. Still identifying a person's primary method by which he or she processes information can be a critical asset if we want to communicate effectively. The reason it is critical to know the channel which a person generally processes information is that if we use that channel to send that information, it makes it easy for the person hearing the message to understand and retain the information contained therein.
