Abstract

Information processing speed (IPS) evaluates the time at which a person reacts to a stimulus. The Wechsler for Adults-III (WAIS-III) includes this domain in the digit symbol test (DS-T).

Objective: The aim of this study was to validate a new screening test that could measure the IPS in association with the individual's age and scholarship.

Methods: A new instrument to measure the IPS was constructed, automatic cashier test (AC-T), and for its validation, the DS-T was also carried out.

Results: The media of time use in the ACT was 12.3 s; the media of hits in the DS-T was 38.8, with a p<0.0001 and R²: 0.40.

Conclusion: P-value showed a linear association between the two tests, but the R² results showed a low association between these. In the same way, the correlation between both tests is promising, since it shows that both are tests that measure the IPS in a different way with different constructs such as the verbal fluency test that is also used to evaluate IPS. On the other hand, both tests exposed that the scholarship positively influences the IPS.

一种评价信息处理速度的新筛选测验并发效度。

信息处理速度（IPS）评估一个人对刺激作出反应的时间。成人韦氏词典- iii （WAIS-III）在数字符号测试（DS-T）中包括了这个域。目的：本研究的目的是验证一种新的筛选试验，可以测量IPS与个人的年龄和学术关系。方法：建立了一种新的IPS检测仪器——自动收银试验（AC-T），并采用DS-T对其进行验证。结果：ACT的时间使用介质为12.3 s；DS-T的命中率为38.8,p = 0.40。结论：两项检验的p值呈线性相关，但R2结果显示相关性较低。同样，这两个测试之间的相关性是有希望的，因为它表明这两个测试都是用不同的方式和不同的结构来测量IPS，比如也用于评估IPS的语言流畅性测试。另一方面，两项测试都表明奖学金对IPS有积极影响。
