雙語閱讀:用跳舞討好女人?不要甩胳膊太多

Dazzling a woman on the dance floor is a tricky challenge for a chap. Now science has come to the rescue, with a move-by-move analysis of what makes a man a good dancer.

在舞池裏用花哨的舞技征服女人，這對小夥子們來說可是一個不容易搞定的挑戰。如今科學出面幫忙，科學家通過分析每個舞蹈動作，最終找到了如何讓男人成爲優秀舞者的答案。

Psychologists asked 19 young men to dance to a drum beat from a German nightclub tune. Their impromptu routines were recorded on special 3D cameras and then transferred onto featureless computer characters. This allowed a panel of 35 women to judge their performances without being influenced by the dancers' looks.

心理學家首先讓19爲年輕男士隨着一段德國夜店曲調的鼓點跳舞。他們的即興動作被錄入3D攝像機，而每個人都被轉錄成毫無特徵的計算機人。這使得35位女性在評判他們的表現時不會因舞者的相貌受到影響。

The women rated the men's ability on the dance floor and the scientific team worked out which moves had made the difference. It appears the mistake most men make is to use their arms too much.

女士們給男士在舞池裏的舞蹈能力打分，然後科研小組分析是哪些動作決定了舞蹈的好壞。結果發現，大部分男性犯的錯誤似乎是胳膊甩得太多了。

Researcher Nick Neave said: "Good dancers made big and small movements." Variability shows creativity. "They did a little head nod with a big body twist and a big head movement and a small body twist." It is thought that such twists and turns of the neck and torso are attractive because they signal a strong, healthy and flexible body.

研究人員尼克-尼夫說：“好的舞者動作有大有小。”舞蹈動作的多變顯示出一個人的創造力。“他們輕輕點頭，同時身體大幅度轉動，然後頭部動作幅度加大，身體小幅扭動。”女人們認爲脖頸和身軀的轉動和扭轉代表着身體強壯、健康和具有柔韌性，故而具有吸引力。

Those flagging on the floor find it hard to do such moves for any length of time and so often resort to exaggerated swings and flings of their arms and legs. These, however, do nothing to attract women – with the exception of the right knee. Flicked in and out and twisted from side to side at speed, a nifty knee apparently catches a lady's eye. This is the first study to show objectively what differentiates a good dancer from a bad one.

而那些舞池中的失意者們覺得這種舞蹈動作難以實現，於是求助於誇張的搖擺和甩胳膊甩腿。然而這些對於吸引女人來說毫無用處——除了右膝蓋。向裏向外快速移動膝蓋以及快速轉動膝蓋，只要做得漂亮利落，你足以獲得女士的青睞。該項研究首次分析了是什麼導致了舞蹈好壞之分。
