ABSTRACT

Mirrored stimuli in chronometric mental rotation tests cannot be rotated into congruence and are typically discarded from analysis. We present a novel design using three figures such that congruence is achieved for all trials. For design construction, we consider the geometrical properties of rotation and mirroring. We have experimentally tested the approach with forty-one German sport students. Results analyzed with linear mixed modeling show small differences but are comparable to the classical two-figure design. Based on our findings we suggest our new layout for future chronometric mental rotation. This will improve analysis of accuracies while increasing power. Moreover, we present a database of cube figures and code for flexible generation of stimuli, which we make available on GitHub at https://github.com/LeonardoJost/MRlibrary.

摘要

计时精神旋转测试中的镜像刺激无法旋转为全等，通常会从分析中丢弃。我们提出了一个使用三个数字的新颖设计，以便在所有试验中均能达到一致。对于设计构造，我们考虑旋转和镜像的几何特性。我们已经对41名德国体育专业学生进行了实验测试。用线性混合建模分析的结果显示出很小的差异，但与经典的两位数设计相当。根据我们的发现，我们建议为将来的计时心理旋转设计新的布局。这将在提高功率的同时改善对精度的分析。此外，我们提供了一个多维数据集和用于灵活生成刺激的代码的数据库，我们可以在GitHub上的https://github.com/LeonardoJost/MRlibrary上获得该数据库。
