Psychologists at Knox College in Galesburg, Ill., enrolled 30 male students in what they described as a taste study. The researchers took saliva samples from the students and measured testosterone levels. They then seated the young men, one at a time, at a table in a bare room; on the table were pieces of paper and either the board game Mouse Trap or a large handgun. Their instructions: take apart the game or the gun and write directions for assembly and disassembly.
Fifteen minutes later, the psychologists measured saliva testosterone again and found that the levels had spiked in men who had handled the gun but had stayed steady in those working with the board game.
