Abstract：
Researchers have identified kinematic differences between deceptive and non-deceptive rugby reorientation actions. However, the honest and deceptive signals corresponded to \'deception detection\' (accuracy increasing) rather than signals that caused deception (accuracy decreasing). In this study, statistical parametric mapping and multilevel modelling were applied to examine the kinematic differences between sidestep and non-deceptive actions during the time window of deception. The analysis compared three-dimensional motion capture data from 144 deceptive actions and 144 genuine actions performed by six high-skilled rugby players. Results indicated that the kinematics of deceptive actions were characterized by a combination of exaggerated head roll, outside foot and centre-of-mass displacement, and attenuated thorax roll and yaw relative to genuine actions. These are candidate sources for the cause of deception, either individually or in combination with other sources. Furthermore, the results indicate that previously identified \'honest\' signals may not be reliable sources of information earlier in the action sequence.
摘要：
研究人员已经确定了欺骗性和非欺骗性橄榄球重新定向行动之间的运动学差异。然而,诚实和欺骗性的信号对应于“欺骗检测”（准确性提高），而不是导致欺骗的信号（准确性降低）。在这项研究中,统计参数映射和多级建模被用来检查在欺骗的时间窗口期间，回避和非欺骗行为之间的运动学差异。该分析比较了来自144个欺骗性动作和六名高技能橄榄球运动员执行的144个真实动作的三维动作捕获数据。结果表明，欺骗性行为的运动学特征是夸大的头部滚动，外侧脚和质心位移，相对于真实动作，胸部滚动和偏航减弱。这些是欺骗原因的候选来源，单独或与其他来源结合使用。此外，结果表明，先前识别的“诚实”信号可能不是行动序列早期的可靠信息来源。
