Albert Mahrabian found that 37% of our communication transmission is made up of tone. Now there is a little glitch in our genetic code to make this a little more interesting. 37% is a considerable amount of communication to be tied up in tone alone if you happen to be half of the population that doesn’t hear all of the tones. It has been found that on average women hear 5-8 tones in communication whereas men hear 35 tones.
We mostly received examples of tonal errors when we were scolded by our mothers as children for our tone of voice and not quite understanding the reprimand. How many times then did you say ‘sorry’ and have the result of the individual responding you didn’t mean it? As adults we have all used the word “fine” to mean that “later, you are going to pay dearly that I’m not happy” without really knowing if the communication was received.
Now communication is usually slated into to forms – indirect and direct. Women are reportedly to speak indirectly while males are reported to speak directly. What this is trying to account for is historical adaptations in communication that have taken form since the days of Hunters & Gatherers. In the Hunter-Gather days women tended to be the gatherers and men tended to be the hunters. The adaptation was created something like this...
Hunters spent most of their time with groups of other hunters or men going to hunt. Going to the hunt was similar to the ways today’s men currently go fishing or attend or watch a sporting event. They quickly work out a plan of attack, where they are going to go, when they get to the area of the hunt. Once they get to the area of attack they stop talking using words for directives and instruction – straight to the point – so to not scare their prey away. This type of emotionless, less tonal communication is prevalent in business. Male brains adapted the direct type of communication because of their tasks during the course of history (Remember Anne Moir found that 80% of males and 10% of women have focus brains which also supports this theory).
Gatherers spent time with other women, children, and the elders of the tribe. They couldn’t just relay on directive communication because some of the individuals they were dealing with didn’t speak. The Gatherers were responsible for taking care of the community when the Hunters were going out getting the kill. They developed ways of seeing and hearing emotions and developed tone references. As with the Hunters, the Gatherers developed adaptations in their brain to deal with the world they dealt with.
Recent studies of male and female brains reveal that the communication areas for a females to be larger in volume with many more communication centers than their male counterparts.

This brain picture shows the communication centers in the male brain (designated by the blue areas) and the communication centers in the female brain (designated by the red areas).
One of the final frontiers is the human brain. Current research reports that we change our brain with every conversation, every action we partake in. Our brain keeps changing and developing well into our 80’s (current research states 80’s but it could be longer). Just because your biological hand may have dealt you a certain brain style doesn’t mean you can’t change, build, and reconstruct your brain. If you communicate indirectly you can practice communicating directly with a direct speaker. If you are a direct speaker you can work with an indirect speaker to build up your ability to speak indirectly.
