So what's more important—money or social standing? It might be the latter, according to two new studies published in the journal Neuron. 
 
"Our study shows that both behaviorally and in the brain, people place an importance on social status," says Caroline Zink, a postdoctoral fellow in neuroscience at the National Institute of Mental Health (NIMH) in Bethesda, Md., and co-author of one of studies. "It's hugely influential even [when we're not] in direct competition with someone else." 
 
Zink's NIMH team and their counterparts at Japan's National Institute for Physiological Sciences (NIPS) used different methods to determine that we process social values in the striatum, which had previously been tapped as our <a href="https://www.scientificamerican.com/article.cfm?id=microeconomic-theory-in-the-brain" dir="ltr">brain's monetary reward center</a>. This is key, researchers say, because it provides evidence that our brains consider a good rep—as well as cash—to be rewarding and worth considering as we mull our options. In addition, they note that our brains likely weigh the benefits of each against one another (because they are processed in the same place) as we make up our minds. 
 
"Although we intuitively know that a <a href="https://www.scientificamerican.com/article.cfm?id=the-samaritan-paradox" dir="ltr">good reputation makes us feel good</a>, the idea that a good reputation is a 'reward' had long been just an assumption without scientific proof," says Norihiro Sadato, a neuroscience professor at NIPS and a co-author of <a href="http://www.sciencedirect.com/science?_ob=ArticleURL&amp;_udi=B6WSS-4SBRRK2-H&amp;_user=10&amp;_rdoc=1&amp;_fmt=&amp;_orig=search&amp;_sort=d&amp;view=c&amp;_acct=C000050221&amp;_version=1&amp;_urlVersion=0&amp;_userid=10&amp;md5=3d8b72948d285dd935f58f9d84155255" dir="ltr">the Japanese study</a>. 
 
Sadato and colleagues conducted fMRI scans of the brains of 19 subjects while they engaged in two different exercises. The first task was a simple game in which participants had to choose one of three cards in the hope of winning a cash prize. In the second game, fictional evaluators appraised volunteers' characters based on the results of personality trait questionnaires. The researchers found that the striatum activated in response to high and low appraisals (but did not perk up to more neutral comments); it also responded to monetary wins and losses but was quiet if a player broke even. 
 
"The implication of our study is that the different types of the reward are coded by the same currency system,'' says Sadato, "enabling the comparison between them."

"We found that the brain reacts very strongly to the other players and specifically the status of the other players," Zink says.
