分组是一种完善的数字感知策略,可提高速度和感觉精度。基于ATOM理论,Anobile提出了感觉运动数字系统,这表明数字和行动之间有着密切的联系。以前使用电机适应技术的研究表明,高频电机适应会导致对数字感知的低估,而低频适应会导致高估。然而,运动适应对成群的影响,以及视觉运动适应是否会产生类似的效果,仍然不清楚。在这项研究中,我们研究了运动适应后群体优势的持久性,并探讨了视觉运动适应的影响。令人惊讶的是,我们的发现表明,本体感觉运动适应削弱了群体化的优势,表明即使采用分组,运动适应也有强大的效果。此外,我们观察到双向关系,因为成群也削弱了适应效果。这些结果突显了运动适应与数字感知中的群体之间复杂的相互作用。此外,我们的研究提供了证据,表明视觉运动适应也有适应效应,但不能完全复制本体感觉运动适应对成群的影响。总之,我们的研究强调了分组作为数字感知中一种有价值的策略的重要性,并阐明了运动适应对该策略的影响。
Groupitizing is a well-established strategy in numerosity perception that enhances speed and sensory precision. Building on the
ATOM theory, Anobile proposed the sensorimotor numerosity system, which posits a strong link between number and action. Previous studies using motor adaptation technology have shown that high-frequency motor adaptation leads to underestimation of numerosity perception, while low-frequency adaptation leads to overestimation. However, the impact of motor adaptation on groupitizing, and whether visual motion adaptation produces similar effects, remain unclear. In this study, we investigate the persistence of the advantage of groupitizing after motor adaptation and explore the effects of visual motion adaptation. Surprisingly, our findings reveal that proprioceptive motor adaptation weakens the advantage of groupitizing, indicating a robust effect of motor adaptation even when groupitizing is employed. Moreover, we observe a bidirectional relationship, as groupitizing also weakens the adaptation effect. These results highlight the complex interplay between motor adaptation and groupitizing in numerosity perception. Furthermore, our study provides evidence that visual motion adaptation also has an adaptation effect, but does not fully replicate the effects of proprioceptive motor adaptation on groupitizing. In conclusion, our research underscores the importance of groupitizing as a valuable strategy in numerosity perception, and sheds light on the influence of motion adaptation on this strategy.
