It's long been known that the use of emotion in communication is a very powerful device. It's not always been used to the best ends and we have a history of people who have used emotion to manipulate people. But actually what we need to recognise is that emotion in communications is a really powerful way of getting our messages across and used appropriately can be highly effective. Now, what's happening when people are using emotion is that we're using something called neuroscience. I'm sure you've probably heard of neuroscience. It's the science of the brain and the activity within the brain. But how can internal communicators use neuroscience principles to make their communications more effective.
