Dopamine Affects Work Attitudes

Friday, 04 May 2012 04:12 PM




Are you a clock-watcher or workhorse on the job? The answer may have as much to do with your brain chemistry as your work ethic, new research shows.
Vanderbilt University researchers have found an individual's willingness to work hard to earn money is strongly influenced by the chemistry in three specific areas of the brain. In addition to shedding new light workplace issues, the findings could suggest new treatment options for attention deficit disorder, depression, schizophrenia and other mental illnesses characterized by decreased motivation.
The study, published in the Journal of Neuroscience, involved a brain mapping technique called positron emission tomography that allowed researchers to track the brain acitivity of workplace "go-getters" and “slackers.”
They found hard-working individuals had higher releases of the chemical dopamine in areas of the brain associated with rewards and motivation. By contrast, those less willing to work hard high dopamine levels in another brain area associated with emotion and risk perception.
"Past studies in rats have shown that dopamine is crucial for reward motivation," the researchers said, "but this study provides new information about how dopamine determines individual differences in the behavior of human reward-seekers."
The study involved 25 healthy volunteers (52 percent female) ranging in age from 18 to 29 who were asked to perform a button-pushing task that assessed their willingness to work harder for more monetary rewards.
