There may be something like that, since Arata apparently "refused" to help Kuroiwa during his fight with Yoshimura during the Aogiri Raid. But, at the same time, Arata worked just fine the second time, so it could have just been a malfunction.

I think in Kaneki's case it had more to do with him losing his mind due to the torture and resorting to hallucinations to maintain his sanity.
