Objective.通常，认知的临床测量需要运动或言语反应。因此，很大比例的残疾人无法完成标准化评估。这种情况可以通过采用更容易获得的测试管理方法来解决，例如脑机接口（BCI）。BCI可以通过翻译大脑活动来识别受试者的反应，从而绕过运动和语言要求。通过消除对运动或语音输入的需要，人们可以使用BCI来评估以前无法获得临床测试的个体。Approach.我们开发了一个异步的，事件相关的潜在BCI促进管理程序的皮博迪图片词汇测试（PPVT-IV）。然后，我们在典型发育个体（N = 11）以及脑瘫患者（N = 19）中测试了我们的系统，以将结果与标准化PPVT-IV格式和管理进行比较。主要结果。BCI辅助PPVT-IV的标准评分与标准PPVT-IV高度相关（r = 0.95，p < 0.001），平均差异为2.0 +/- 6.4分，在PPVT-IV的标准误差范围内。意义因此，我们的BCI促进PPVT-IV提供了与标准PPVT-IV相当的结果，这表明无法获得标准化认知测试的人群可以从我们的BCI促进方法中受益。
Objective. Typically, clinical measures of cognition require motor or speech responses. Thus, a significant percentage of people with disabilities are not able to complete standardized assessments. This situation could be resolved by employing a more accessible test administration method, such as a brain-computer interface (BCI). A BCI can circumvent motor and speech requirements by translating brain activity to identify a subject's response. By eliminating the need for motor or speech input, one could use a BCI to assess an individual who previously did not have access to clinical tests. Approach. We developed an asynchronous, event-related potential BCI-facilitated administration procedure for the peabody picture vocabulary test (PPVT-IV). We then tested our system in typically developing individuals (N = 11), as well as people with cerebral palsy (N = 19) to compare results to the standardized PPVT-IV format and administration. Main results. Standard scores on the BCI-facilitated PPVT-IV, and the standard PPVT-IV were highly correlated (r = 0.95, p < 0.001), with a mean difference of 2.0 +/- 6.4 points, which is within the standard error of the PPVT-IV. Significance. Thus, our BCI-facilitated PPVT-IV provided comparable results to the standard PPVT-IV, suggesting that populations for whom standardized cognitive tests are not accessible could benefit from our BCI-facilitated approach.
