The stochastic process of occurrence of errors in a simple and monotonous task was investigated. Previous studies used the task of adding pairs of numbers such as Kraepelin Test, and found that the group data fitted well to the Pólya-Eggenberger distribution. It was inferred from this fact that the occurrence of errors in the individual subject obeyed the Poisson distribution and the Poisson parameter indicating the individual difference was distributed as the Gamma. Because the occurrence of errors is rather rare in the test, it is difficult to verify the above inference in individual data. In this report, in order to identify intra-individual distributions, we used "Amefuri" test as a task in which more errors could be expected to occur, and we could identify the distributions without prolonging the test period. It may be compared to the method of accelerated life test in Reliability Engineering.
