Nothing wrong with your Google-fu – I just searched for the article title in Chinese (found the Chinese title through the third English result; my rudimentary understanding of Chinese helped a little since the position of the title is not obvious on that page).

I just had a brief look at the tables and tried to translate them, but it turns out that my Chinese sucks too much... My lack of familiarity with n-back studies doesn't help. I can probably help translate very short phrases, but I'm not really able to understand the context.
