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.

研究人员尼克-尼夫说：“好的舞者动作有大有小。”舞蹈动作的多变显示出一个人的创造力。“他们轻轻点头，同时身体大幅度转动，然后头部动作幅度加大，身体小幅扭动。”女人们认为脖颈和身躯的转动和扭转代表着身体强壮、健康和具有柔韧性，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们觉得这种舞蹈动作难以实现，于是求助于夸张的摇摆和甩胳膊甩腿。然而这些对于吸引女人来说毫无用处——除了右膝盖。向里向外快速移动膝盖以及快速转动膝盖，只要做得漂亮利落，你足以获得女士的青睐。该项研究首次分析了是什么导致了舞蹈好坏之分。
