Motivation to be active may lead to impulsive behavior

Those motivated to actively change bad habits may be setting themselves up for failure, a new study suggests. The study, described in an article in the journal Motivation and Emotion, found that people primed with words suggesting action were more likely than others to make impulsive decisions that undermined their long-term goals. In contrast, those primed to "rest," to "stop" or to be inactive found it easier to avoid impulsive decisions.

"Popular views of self-control maintain that individuals should 'exert' willpower, 'fight' temptations, 'overcome' desires and 'control' impulses when they want to successfully control their own behavior," said University of Illinois graduate student Justin Hepler, who led the study with psychology professor Dolores Albarracín.

"Ironically, in these situations people are often 'fighting' to do nothing -- for example, they want to not eat a piece of cake."

"Those who try to be active may make wild, risky investments, for example, and persist in behaviors that clearly make them unsuccessful," Albarracín said.

Hepler, Albarracín and colleagues at Idaho State University and the University of Southern Mississippi wanted to determine whether successful self-control involves the active, effortful pursuit of one's goals, as some researchers have proposed, or whether one is more likely to succeed by "delay(ing) behavior until sufficient pre-action information processing has occurred," as others suggest, the researchers wrote.
