Honest Signals (Petland, 2010, The MIT Press)
“For the fi rst time, we can precisely map the behavior of large numbers of people as they go about their normal lives. By using cell phones and electronic badges with integrated sensors, my students and I have observed hundreds of participants for periods of up to a year. In the process we amassed hundreds of thousands of hours of detailed, quantitative data about natural, day-to-day human behavior—far more data of these kind than have ever been available before. A new measurement tool such as this often brings with it a new understanding of what you are measuring. What we have found is that many types of human behavior can be reliably predicted from biologically based honest signaling behaviors. These ancient primate signaling mechanisms, such as the amount of synchrony, mimicry, activity, and emphasis, form an unconscious channel of communication between people—a channel almost unexplored except in other apes” http://www.amazon.com/Honest-Signals-Shape-World-Bradford/dp/0262515121/ref=s…
