But new research from Vanderbilt finds that these individuals–labeled as novelty seekers by psychologists–face an uphill battle in keeping their New Year’s resolutions due to the way their brains process dopamine. The research reveals that novelty seekers have less of a particular type of dopamine receptor, which may lead them to seek out novel and exciting experiences–such as spending lavishly, taking risks and partying like there’s no tomorrow.

Their study is the first to examine adult attitudes about the health risks to children of third-hand smoke and how those beliefs may relate to rules about smoking in their homes.
