Caveman behavioral traits might kick in at Thanksgiving table before eating

Frank Kachanoff was surprised. He thought the sight of meat on the table would make people more aggressive, not less. After all, dont football coaches feed their players big hunks of red meat before a game in hopes of pumping them up? And what about our images of a grunting or growling animal snarling at anyone who dares take their meat away from them? Wouldnt that go for humans, too?

Kachanoff, a researcher with a special interest in evolution at McGill Universitys Department of Psychology, has discovered quite the reverse. According to research presented at a recent symposium at McGill, seeing meat appears to make human beings significantly less aggressive. I was inspired by research on priming and aggression, that has shown that just looking at an object which is learned to be associated with aggression, such as a gun, can make someone more likely to behave aggressively. I wanted to know if we might respond aggressively to certain stimuli in our environment not because of learned associations, but because of an innate predisposition. I wanted to know if just looking at the meat would suffice to provoke an aggressive behavior.

The idea that meat would illicit aggressive behaviour makes sense, as it would have helped our primate ancestors with hunting, co-opting and protecting their meat resources. Kachanoff believed that humans may therefore have evolved an innate predisposition to respond aggressively towards meat, and recruited 82 males to test his theory, using long-established techniques for provoking and measuring aggression. The experiment itself was quite simple subjects had to punish a script reader every time he made an error while sorting photos, some with pictures of meat, and others with neutral imagery. The subjects believed that they could inflict various volumes of sound, including painful, to the
