[Q]: 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.

[Q]: Article: My husband can plan wonderful surprise celebrations for me.Recently,however,I told him I didn't want him to plan one for my upcoming birthday. "Why?" he asked. "I am embarrassed being the center of attention," I quickly explained. Later,I began to think more deeply about this reason. Then I remembered the surprise celebration I had planned for my friend Nancy on her 60th birthday. We were roommates on a threeweek tour following the Silk Road on those famous steppes --and through the mountains--of central Asia. That afternoon we had arrived at our hotel in Samarkand,Uzbekistan. The young man at the hotel desk told me about a bakery about 10 minutes away. After giving me detailed directions,he added,"Your nose will let you know when you arrive there." The temperature was 40 degC.Soon, _ proved to be an unfailing guide. Outside the bakery,a delicious smell greeted me. There were several kinds of breads,cookies,and cakes on display. There were also beautiful iced cakes. I chose a cake topped with powdered sugar. Later at the Karim Bek Restaurant,Nancy didn't see the young waiter walk up the steps with the cake.When I began singing"Happy Birthday,"everyone at our table--except Nancy--joined in. It took her a moment to realize what was happening. Then the grinning guest of honor thanked me,blew out the candles on the cake,and ate three pieces of it. Today,after reliving this experience in my mind,I told my husband to ignore my request.I now understand what a surprise party is about:It is not about having a surprise party but rather the delight in giving it. That is what brings the satisfying joy.
Answer: To eat some iced cakes to cool herself down.

[Q]: Article: Waiting anxiously to be reunited with the son he had not seen for 13 years, Phil Baker took a walk along the beach with his wife Lyn to relax himself. His boy Benji, 21, was finally back to Australia after living most of his life in the UK, half a world away from his dad. As he looked out at the ocean, wondering how his son might have changed over the years, Phil saw some people on the kayaks in trouble on the water. Without hesitation, he dived into the sea to help. And as he carried a stricken young man trembling and semi-conscious to the shore, he realized the young man was his long-lost son. "I looked at his face, and something occurred to me," says Phil. "Those brown eyes were very familiar." Although Phil had seen just a few photos of his son since the boy was eight years old, he recognized him at once. It would be reasonable to suppose it was a father's instinct that _ Phil to help ---- but at the moment he dived into the water to go to the aid of the struggling group, he only thought he was helping a stranger in trouble. He said, "Two people were desperately paddling on one of the kayaks and it seemed like someone fell into the water. I told Lyn, 'Something is not right; I'm going to help.' " "l took off my T-shirt and threw my keys on the sand. Diving into the water, I saw there were two instructors on board and a man lying in the water. He was shaking violently. Linking arms with one instructor, I helped to carry the man out of the water. He was drifting in and out of consciousness and his hands and feet were blue." Then Phil looked into the boy's eyes and wept as he realized the stricken stranger was his own son. Phil recalled, "I asked the instructor, 'what's his name?' " He replied, 'Benji'. In an instant, I knew that stranger was my boy. I checked his breathing and pulse and said, "It's me, your dad. You're going to be OK." Benji tells how it felt to be saved by his long-lost dad. "All I remember was waking up on the beach and seeing my dad there," he says, "And I recognized his face straight away."
