FRIDAY, Nov. 12 (HealthDay News) -- That feeling of goodwill
when family and friends gather for the Thanksgiving meal may be due
to the fact that the sight of meat on the table calms people, a new
The researchers in the psychology department at McGill
University in Montreal were surprised by their finding. They had
expected that seeing meat would make people more 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," study author Frank Kachanoff said in a McGill news release.
"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," he explained.
Kachanoff thought meat would trigger aggression in people
because he believed this type of behavior would have helped our
primate ancestors survive.
The study included 82 males who sorted sets of photos while
listening to a person read a script. Some sets of photos were of
ready-to-eat meat while others had neutral imagery. Every time the
script reader made an error, the participants could use various
levels of sound to inflict punishment.
Contrary to what the researchers expected, the participants who
sorted photos of meat were calm.
"In terms of behavior, with the benefit of hindsight, it would make sense that our ancestors would be calm, as they would be surrounded by friends and family at meal time," Kachanoff said. "I would like to run this experiment again, using hunting images. Perhaps Thanksgiving next year will be a great opportunity for a do-over!"
