A power-space interaction, which denotes the phenomenon that people responded faster to powerful words with up cursor keys and faster to powerless words with down cursor keys, has been repeatedly found. In the present study, we took an individual differences approach to investigate how the power-space interaction is modulated by the spatial cognition. First, we found that the amplitude of power-space interaction was relatively stable within individuals across different stimuli. And, this individual difference in power-space interaction was correlated with the individual's spatial cognition, in such a way that participants with faster speed of mental rotation showed stronger power-space interactions. Our results shed new light on the cognitive mechanisms of the power-space associations by suggesting that spatial codes play an important role in the expression of such effect.
一种力-空间相互作用被反复发现，它表示人们对用向上光标键表示的有力词汇的反应比用向下光标键表示的无力词汇更快。在本研究中，我们采用个体差异的方法来探究力-空间相互作用是如何被空间认知所调节的。首先，我们发现，个体在不同刺激下的力-空间相互作用的振幅相对稳定。并且，这种力-空间相互作用的个体差异与个体的空间认知有关，即心理旋转速度较快的参与者表现出更强的力-空间相互作用。我们的结果通过表明空间编码在表达这种效应中起着重要作用，为力-空间联想的认知机制提供了新的见解。
