Time pressures had the strongest link to anger, especially low-grade versions termed "feelings of annoyance," the study found.
Those who were under financial strain tended to report higher levels of anger, a connection that could be particularly important in today's flagging economy, Schieman noted. The financial influence tended to be stronger among women and younger adults.
Having children was also associated with angry feelings and behaviors, such as yelling, particularly in women, the survey found.
"There's obviously a lot of joys and benefits that come with parenthood," but other aspects of parenting, such as having to discipline a misbehaving child, can cause feelings of anger and annoyance, Schieman said.
Those with fewer years of education were also more likely to report feelings of anger and were less likely to respond proactively in a situation that made them angry (for example, talking about what made them angry).
"It underscores the power of getting more education," Schieman said. Education has been linked to feeling more self-control, which could be why those with more education tend to manage their anger more proactively, he told LiveScience.
Even angry Americans can laugh.
It seems to me that the Americans are a lot more angry than some other nationalities.
a more noble, self-sacrificing creature if there ever was one.
