自1971年发展以来，Corsi区块敲击(CB)任务一直被用作空间记忆的测量工具。然而，还没有为这项任务制定一套标准的项目，而且由于路径配置的不同，水平内的绩效不一致。这项研究通过分析94名年轻成年参与者在一项块敲击任务中的表现来考察项目的一致性，该任务包括五个准随机确定的序列，每个序列在九个难度水平上。一般而言，性能随着路径长度的增加而下降。对每个水平内的项目进行了Cochran q检验比较，并仅在水平7和8确定了不同的表现。两两比较确定了性能差异的特定项目，进一步分析表明，性能降低与更复杂的块攻丝路径有关。研究结果表明，这一版本的CB任务总体上是相对一致的，路径配置的观察结果间接证实了这一任务的空间性质。更高级别的性能异构性反映了更复杂的路径配置以及可能更大的跨区容量负载。在空间(结构)记忆任务的临床应用中，应考虑不同水平内项目的一致性，以避免对基于水平内失败的持续注意能力的错误解读。
The Corsi Block-Tapping (CB) task has been used as a measure of spatial memory since its development in 1971. However, a standard set of items has not been developed for this task, and inconsistencies in performances within levels have been demonstrated in association with different path configurations. This study investigated item consistency by analyzing the performances of 94 young adult participants on a block-tapping task that involved five quasi-randomly determined sequences at each of nine levels of difficulty. In general, performance declined with increasing path length. Cochran Q-test comparisons were conducted on the items within each level, and differential performances were identified at levels 7 and 8 only. Pairwise comparisons determined the specific items for which performance was discrepant, and further analysis indicated that performance decrements were related to more complicated block-tapping paths. The findings suggest that this version of the CB task is relatively consistent overall, and the observed effect of path configuration indirectly corroborates the spatial nature of this task. Performance heterogeneity at higher levels reflected more complicated path configuration and, presumably, greater span capacity load. Differential intra-level item consistency should be considered in clinical applications of spatial (configural) memory tasks in order to avoid erroneous interpretations concerning sustained attention ability based on failures within levels.
