CNV magnitude was studied in a task involving spatial localization and discrimination Subjects were 18 children 10 years of age. The CNV amplitude of half the subjects increased when the performance decreased and, in the other half, CNV amplitude decreased when the performance decreased. However, it seems that CNV magnitude increases as task difficulty increases but only above a minimal threshold varying with the subject. The results suggest that CNV amplitude cannot be related to a single psychological factor.
在一项涉及空间定位和辨别的任务中研究了关联性负变化（CNV）的大小。受试者为18名10岁儿童。一半受试者的CNV波幅在表现下降时增加，而另一半受试者的CNV波幅在表现下降时减小。然而，似乎CNV大小随着任务难度的增加而增加，但仅在随受试者而变化的最小阈值之上。结果表明，CNV波幅不能与单一心理因素相关联。
