本文扩展了我们之前的研究(信纸)，该研究基于源代码阅读过程中近红外光谱(NIRS)测量的大脑激活来量化程序理解的难度。我们对20名受试者进行了对照实验。20名受试者中有3名未能完成测量。研究发现：(1)17人中有16人在阅读模糊程序时表现出较强的脑激活(二项检验，p<；0.01)；(2)主观难度评价与脑激活相关(Spearman‘s相关系数=0.46，p<；0.01)。
This paper extends our previous study (letter paper), which quantifies the difficulty of program comprehension based on brain activation measured by NIRS (Near Infra-Red Spectroscopy) during source code reading. We performed controlled experiments with 20 subjects. 3 of 20 subjects could not complete the measurement. We found that:(1) 16 of 17 shows strong brain activation during reading of obfuscated program (binomial test,p< 0.01) and (2) subjective evaluation of difficulty is correlated with brain activation (Spearman's correlation coefficient= 0.46,p< 0.01).
