我们研究了艾宾浩斯错觉在儿童感知和抓取中的发展。先前的一项研究（Hanisch et al. 2001）报告了5- 12岁儿童的抓取能力与感知能力相比，错觉的负面影响。我们试图重复这一发现，并基于上下文元素对手指轨迹的直接影响来测试不同的假设，这可以解释错觉效应的逆转。对于5到7岁和9到11岁的孩子，我们观察了知觉中的经典错觉效应。9 ~ 11岁儿童在感知和抓握方面的错觉效应完全相似，而5 ~ 7岁儿童在抓握方面的错觉效应有不显著的减小趋势。这可能是由于错觉对年幼儿童抓取的影响略有不同。然而，似乎很明显，没有质变，作为错觉效应的逆转，在年幼的孩子的抓取。最后，我们表明我们的抓取数据与儿童抓取的运动文献很好地吻合，从而加强了我们的结论。
We investigated the development of the Ebbinghaus illusion in children’s perception and grasping. A previous study (Hanisch et al. 2001) had reported negative illusion effects on 5- to 12-year-olds’ grasping as compared to their perception. We attempted to replicate this finding and to test different hypotheses based on a direct influence of the context elements on the trajectories of the fingers which could explain this reversal of the illusion effects. For 5- to 7- and 9- to 11-year-olds we observed the classical illusion effects in perception. Illusion effects were perfectly similar for perception and grasping in 9- to 11-year-olds, while there was a non-significant trend toward smaller illusion effects in grasping for the 5- to 7-year-olds. This could be due to a slightly different effect of the illusion on younger children’s grasping. However, it seems clear that there are no qualitative changes, as a reversal of the illusion effects in grasping of younger children. Finally, we show that our grasping data conform well to the motor literature for children’s grasping, thereby strengthening our conclusions.
