In „A Theory Of Magnitude“ (ATOM), Walsh (2003, 2015) postulates a generalized (brain) system for the processing of different “magnitudes” (e.g., size, space, time) that are relevant for the control of action. ATOM predicts that the concurrent processing of these magnitudes should lead to compatibility or interference effects. Whereas previous research has extensively studied compatibility and interference effects for numerical magnitude and spatial position, and for numerical magnitude and physical size, previous research has neglected the possible consequences of the concurrent processing of physical size and spatial position. In pilot work, we showed a compatibility effect between physical stimulus size and horizontal response position: Participants responded faster to (relatively) small stimuli with the left response (hand) than with the right response (hand), whereas the reverse pattern was observed for (relatively) large stimuli. This stimulus-size response-location compatibility effect (henceforth called: size-location effect) not only occurred when stimulus size was task relevant, but also when stimulus size was task irrelevant (Seegelke & Wühr, 2018; Wühr & Seegelke, 2018). Moreover, preliminary results suggests that the effect occurs for right-handed, but not for left-handed participants. The research project, proposed here, has three general aims. The first aim is to empirically evaluate two possible explanations for the size-location compatibility effect. The first explanation arises from the polarity-correspondence principle proposed by Proctor and colleagues (e.g., Proctor & Xiong, 2015). The second explanation arises from the fact that the dominant hand is usually stronger than the non-dominant hand (at least in right-handed individuals), which might have caused a preference for grasping larger (and often heavier) objects with the dominant hand. The second aim of the project is to uncover similarities and differences between the size-location compatibility effect and the SNARC effect. Therefore, it is planned to directly compare different compatibility effects in different spatial dimensions. Commonalities and differences between the effects might be informative with regard to whether the effects have common or different sources, and whether the effects arise at similar or different stages of processing. The third aim of the project is to further develop ATOM. In its present form (e.g., Walsh, 2015), ATOM merely predicts the existence of (mutual) interference when stimulus size and response location are concurrently processed. But because empirical research on this issue is lacking, ATOM cannot tell much about the causes and characteristics of the interference effects. Moreover, ATOM cannot explain the direction of compatibility (or congruency) effects between non-spatial magnitudes and spatial (location) information. The results of our research project might be useful in filling these empirical and theoretical gaps.

在“A Theory Of Magnitude”（ATOM）中，沃尔什（2003，2015）假设了一个通用的（大脑）系统，用于处理不同的“量级”（例如，大小、空间、时间），这些都与动作控制有关。ATOM预测，同时处理这些幅度应导致兼容性或干扰效应。鉴于以前的研究已经广泛地研究了兼容性和干扰效应的数值大小和空间位置，以及数值大小和物理大小，以前的研究忽略了可能的后果，同时处理的物理大小和空间位置。在试点工作中，我们发现了物理刺激大小和水平反应位置之间的兼容性效应：参与者对（相对）小刺激的反应速度比对（相对）大刺激的反应速度快。这种刺激大小反应位置相容性效应（以下称为：大小位置效应）不仅发生在刺激大小与任务相关时，而且发生在刺激大小与任务无关时（Seegelke & Wühr，2018; Wühr & Seegelke，2018）。此外，初步结果表明，这种效应发生在右撇子身上，但不适用于左撇子。这里提出的研究项目有三个总的目标。第一个目的是实证评估两种可能的解释的大小位置的兼容性效果。第一种解释来自普罗克特及其同事提出的极性对应原理（例如，普罗克特和Xiong，2015年）。第二种解释来自于这样一个事实，即优势手通常比非优势手更强（至少在右撇子个体中是这样），这可能导致了优势手抓握更大（通常更重）的物体的偏好。该项目的第二个目的是揭示大小-位置相容性效应和SNARC效应之间的相似性和差异。因此，计划直接比较不同空间维度的不同兼容性效果。这些效应之间的共同点和差异可能有助于了解这些效应的来源是共同的还是不同的，以及这些效应是在类似的还是不同的加工阶段产生的。该项目的第三个目标是进一步发展原子能机构。以其目前的形式（例如，沃尔什，2015），ATOM仅预测在同时处理刺激大小和响应位置时存在（相互）干扰。但由于缺乏对这一问题的实证研究，ATOM无法对干扰效应的原因和特征做出更多的解释。此外，原子不能解释的方向之间的非空间大小和空间（位置）信息的兼容性（或一致性）的影响。我们的研究项目的结果可能有助于填补这些经验和理论空白。
