| The research was done by a Dr.
Griffiths in England. He compared the behavior of 15 regular gamblers (赌徒) with
those of 15 non-regular gamblers before and after they gambled. Both groups had
increased heart rates during gambling because it was exciting. But the regular
gamblers’ heart rates went down almost straight after the game, while the
non-regulars remained excited and had in- creased heart rates for
longer. When the heart beat increases, the body produces one chemical called endorphins which make you feel good. Dr. Griffiths thinks that regular gamblers lose this good feeling soon after a game and need to play again quickly to regain the pleasure. He has also discovered that regular gamblers have different psychological reactions (心理反应) from non-regular gamblers. In an experiment where regular and non-regular gambler A. Their bodies produce less endorphins during the game. B. They don’t consider losses in a game as reasonable near wins. C. Their bodies have no reaction to beta blockers. D.
