PORTUCÁLIA

Março 28 2012

Depending on your personality, your morning cup of Joe may be counterproductive.  Though the caffeine will certainly wake you up, it may also dampen your desire to work hard, rather than spur you to action.

The study, published online today in the journal Neuropsychopharmacology, found that “worker” rats, those that naturally wanted to work harder for greater rewards, were more likely to avoid hard work when given amphetamine or caffeine.  Only “slacker” rats, those that don’t rise to challenges and aim for small rewards, were motivated by the stimulants.

Researchers from the University of British Columbia set out to examine what motivates people to put out either a lot of effort or a little.

“The degree of effort that we are willing to expend for a goal has far-reaching consequences for our economic and personal success,” the researchers wrote.  

For example, if you’re deciding whether to simply punch the clock at work or to go the extra mile, you weigh the cost of the effort with the potential reward.

The study found that rats fell into two groups: “worker” rats and “slackers,” based on how often they gravitated to high-effort, high-reward activities versus low-effort, low –reward activities.  Humans, too, can fall into these groups, and certain health conditions cause a lack of motivation, including depression and ADHD.

COMENTANDO ; Esta descoberta não deixa de ser surpreendente, embora tenha sido feita inicialmente com ratos de laboratório. O que até agora se acreditava é que o café da manhã estimulava a pessoa e a colocava pronta para enfrentar o "batente" da manhã. A pesquisa mostrou que a coisa não é bem assim. Existem outras variáveis que podem interferir no desempenho da pessoa e fazer com que ela trabalhe a mil ou fique relaxada.
