Why is it impossible for you to pass up that adorable purse on sale, while your friend has no qualms about banking her money for later?
The answer depends on whether you feel good about deferring immediate gratification for future benefits, say researchers at Washington University in St. Louis. Just knowing something good is coming may be pleasurable for some people, but impulsive people show different brain responses. Their brain activity indicates that waiting for a reward isn’t enjoyable. They may be impulsive because they can’t imagine the future, so they prefer to receive rewards
immediately, according to the experts. The researchers say their results may help therapists treat people who have impulsivity problems.
