Article: If you think by examining someone's facial expressions you can judge if he has good or bad luck in the stock market, think again. A study published in the journal, Science, has shown that body language provides a better signal in judging whether the observed subject has just gone through an intensely positive or negative experience. To test highly intense faces, Dr. Hillel Aviezer and his colleagues presented test groups with photos of dozens of highly intense facial expressions in real-life situations. In one study, they compared emotional expressions of professional tennis players winning or losing a point. To discover exactly how people view images, the researchers showed different editions of the pictures to three groups of participants: 1 ) the full picture with the face and body;2) the body with the face removed; 3) the face with the body removed. Remarkably, participants could easily pick the losers from winners when they judged by the full picture or the body alone, but they only had a 50:50 chance of being right when judging by the face alone. Strangely, the participants .who viewed the full image believed that it was the face, not the body, that revealed the person's emotions. In an additional study, the researchers performed the same series of tests, asking viewers to examine a wider range of real-life intense faces. Again, viewers were unable to tell faces in positive situations from negative situations. The researchers also "planted" faces on bodies expressing positive or negative emotions. Sure enough, the researchers discovered that the emotion of the same face on different bodies was determined by the body on which it appeared. "These results show that when emotions become extremely intense, the difference between positive and negative facial expressions no longer seems clear," says Aviezer. "The findings challenge classic behavioral models, in which the boundary between positive and negative emotions is clear." Aviezer adds, "The results may help researchers understand how body and facial expressions interact during emotional situations. For example, individuals with autism may fail to recognize facial expressions, but if trained to read important body language signs, their performance may significantly improve."
Answer: The participants were divided into three groups.

Article: Having a husband means an extra seven hours of housework each week for women, according to a new study. For men, getting married saves an hour of housework a week. "It's a _ ," said lead researcher Frank Stafford at University of Michigan's Institute for Social Research. "Men usually work more outside the home, while women take on more of the housework." He points out that differences among households exist. But in general, marriage means more housework for women and less for men. "And the situation gets worse for women when they have children." Stafford said. Overall, times are changing in the American home. In 1976, women busied themselves with 26 weekly hours of sweeping-and-dusting work, compared with 17 hours in 2005. Men are taking on more housework, more than doubling their housework hours from six in 1976 to 13 in 2005. Single women in their 20s and 30s did the least housework, about 12 weekly hours, while married women in their 60s and 70s did the most - about 21 hours a week. Men showed a somewhat different pattern, with older men picking up the broom more often than younger men. Single men worked the hardest around the house, more than that of all other age groups of married men. Having children increases housework even further. With more than three, for example, wives took on more of the extra work, clocking about 28 hours a week compared with husbands' 10 hours.
