I hadn't seen this, but just commented[1] noting the link between working memory and cyclometic complexity.

I suspect your experimental results might be slightly weakened by the way mechanical Turkers will always do the easiest thing possible to get paid (I've had studies broken by this too). That probably explains this: In fact, we found the preponderance of linear traces somewhat bewildering — participants appeared to just click through each function, remembering what they could and then synthesizing the information into an answer at the end.

Yes, this was my first and probably last experiment using participants from Mechanical Turk. Just too unpredictable.
