The Symbol Digit Modalities Test (SDMT) is an information processing speed test. The aim of this study was to compare the SDMT across three samples: the USA, Mexico, and Argentina. The hypothesis is that performance will vary based on native language and cultural differences between these countries. The SDMT was administered to 129 healthy volunteers. Participants from the USA performed better than participants from Argentina and Mexico ( < .01), and no differences were observed between the latter groups ( = .15). Processing speed differs between the studied populations of Latin America and Anglo-America. Possible interpretations of this result are presented.
符号数字模态测验（SDMT）是一种信息处理速度测试。本研究的目的是比较美国、墨西哥和阿根廷三个样本的SDMT。假设是，这些国家之间的表现会因母语和文化差异而有所不同。对129名健康志愿者进行了SDMT测试。来自美国的参与者表现优于来自阿根廷和墨西哥的参与者（<0.01），而后两组之间未观察到差异（=0.15）。拉丁美洲和盎格鲁美洲的研究人群在处理速度上存在差异。本文给出了这一结果的可能解释。
