The tablet computer initiates an important step toward computerized administration of neuropsychological tests. Because of its lack of standardization, the Corsi Block-Tapping Task could benefit from advantages inherent to computerization. This task, which requires reproduction of a sequence of movements by tapping blocks as demonstrated by an examiner, is widely used as a representative of visuospatial attention and working memory. The aim was to validate a computerized version of the Corsi Task (e-Corsi) by comparing recall accuracy to that on the standard task. Forty university students (Mage = 22.9 years, SD = 2.7 years; 20 female) performed the standard Corsi Task and the e-Corsi on an iPad 3. Results showed higher accuracy in forward reproduction on the standard Corsi compared with the e-Corsi, whereas backward performance was comparable. These divergent performance patterns on the 2 versions (small-to-medium effect sizes) are explained as a result of motor priming and interference effects. This finding implies that computerization has serious consequences for the cognitive concepts that the Corsi Task is assumed to assess. Hence, whereas the e-Corsi was shown to be useful with respect to administration and registration, these findings also stress the need for reconsideration of the underlying theoretical concepts of this task.
平板电脑朝着神经心理学测试的计算机化管理迈出了重要一步。由于缺乏标准化，科西方块敲击任务（Corsi Block-Tapping Task）可以从计算机化所固有的优势中受益。该任务要求被试按照检查者示范的方式敲击方块来再现一系列动作，被广泛用作视觉空间注意力和工作记忆的代表。目的是通过将回忆准确性与标准任务进行比较，来验证科西任务的计算机化版本（电子科西任务，e-Corsi）。40名大学生（年龄中位数Mage = 22.9岁，标准差SD = 2.7岁；20名女性）在iPad 3上完成了标准科西任务和电子科西任务。结果显示，与电子科西任务相比，标准科西任务在前向再现方面的准确性更高，而后向表现相当。这两个版本的不同表现模式（中到小效应量）被解释为运动启动和干扰效应的结果。这一发现意味着计算机化对科西任务假定要评估的认知概念有严重影响。因此，虽然电子科西任务在管理和记录方面被证明是有用的，但这些发现也强调了重新考虑该任务潜在理论概念的必要性。
