HARD-WIRED FOR COLLABORATION: PHYSICAL TOUCH INCREASES PERFORMANCE
Physical touch stengthens creative problem solving and performance. In Born To Be Good: The Science of a Meaningful Life (Norton, 2009), Dacher Keltner cites research indicating that simply giving a reassuring physical touch (a high-five, a chest bump, a shoulder pat) can increase performance on the basketball court, in intimate relationship, in the classroom, everywhere! Humans are wired to seek collaborative effort to "share the load" of problem solving.
