Stimuli associated with large quantities are typically responded to faster with a right- than a left-side key, whereas stimuli associated with small quantities are typically responded to faster with a left- than a right-side key. This phenomenon is known as the spatial-quantity association of response codes (SQUARC) effect. Here, in two experiments, we explored whether a SQUARC effect can emerge for light versus heavy items. Participants judged whether the weight associated with a central target word, describing an animal (e.g. 'cow'; Experiment 1) or a material (e.g. 'iron'; Experiment 2), was lighter or heavier than the weight associated with a reference word. Responses were provided with a left- and a right-side button. Then, participants estimated the weight associated with target and reference words. In both experiments, evidence for a SQUARC effect emerged. Moreover, response times for each target word decreased with absolute difference between its rated weight and the rated weight of the reference word, in line with a distance effect. Overall, these results provide evidence of a possible spatial representation of weight.
与大量相关的刺激通常用右侧按键比左侧按键反应更快，而与少量相关的刺激通常用左侧按键比右侧按键反应更快。这种现象被称为反应编码的空间数量关联（SQUARC）效应。在此，在两项实验中，我们探究了对于轻物品与重物品是否会出现SQUARC效应。参与者判断与描述动物（如“奶牛”；实验1）或材料（如“铁”；实验2）的中心目标词相关的重量比与参考词相关的重量更轻还是更重。通过左侧和右侧按钮进行反应。然后，参与者估计与目标词和参考词相关的重量。在两项实验中，都出现了SQUARC效应的证据。此外，每个目标词的反应时间随着其评定重量与参考词评定重量之间的绝对差异而减少，这与距离效应一致。总体而言，这些结果提供了重量可能存在空间表征的证据。
