Recent research has identified some functions of the brain that make it easier to remain monogamous, particularly for women. When placed in a situation where an outside flirtation is possible, a subconscious alarm is set off and women react by not paying attention to the appealing threat. Instead, they express more commitment to their relationship. Men's brains do not automatically protect their relationships in the same way but can be trained to do so by visualizing and planning how to avoid the enticement. Additional studies have shown that when strong love is at the forefront, it is harder for the brain to pay attention to, perceive and recall the appeal of an attractive outsider.
