This study investigated the relationship between semantic numerical magnitudes and motor magnitudes. We asked whether the processing of numbers can affect motor behavior such as the size of numbers affecting the size of motor actions. For this, we recorded continuous grip force fluctuations from 43 healthy adults during a symbolic magnitude comparison task. We found that numbers induced spontaneous grip force fluctuations during number processing. Smaller numbers induced lower grip forces, whereas larger numbers induced larger forces. This result constitutes strong behavioral support for a generalized magnitude processing by continuously quantifying the response that challenges binary accounts of cross-domain interactions.
本研究调查了语义数值大小与运动大小之间的关系。我们想知道数字的处理是否会影响运动行为，例如数字的大小是否会影响运动动作的大小。为此，我们在 43 名健康成年人进行符号数量比较任务时，记录了他们的连续握力波动。我们发现，在处理数字时，数字会引起自发性的握力波动。较小的数字会引起较小的握力，而较大的数字会引起较大的握力。这一结果为广义的数量处理提供了强有力的行为支持，同时也对跨领域相互作用的二元解释提出了挑战。
