中文摘要：

趋利避害的相容效应是指情绪性刺激与趋避行为之间存在相容性关系。趋避行为的现有定义不一，且常与其他行为混淆，以表征距离变化为标准可以统一趋避行为的定义。动机定向理论是解释趋利避害相容效应的最佳理论，事件编码理论与特定肌肉激活论是对其他现象的解释。用鼠标轨迹这一新的研究范式考察相容效应，或许可以整合已有研究范式的长处，并且具备独特的优势。

英文摘要：

Compatibility exists between positive/negative stimuli and approach/avoidance behaviors. Existing studies disagree on the definition of approach-avoidance behaviors, sometimes confusing them with other types of behaviors. Using ＂representational distance change＂ as a critical criterion can help settle the controversy. Motivation orientation theory is by far the best theoretical framework in explaining the compatibility effect of approaching the positive and avoiding the negative, whereas event coding theory and specific muscle activation account are not as suitable. A new paradigm, exploring compatibility effect with mouse trajectory, may combine the merits of different previous paradigms, and thus has its unique advantages.
