In taking a moment to read the paper more thoroughly, indeed, it does not address the question. I had read this quote:

The response to updates of random patterns was multiphasic, consisting of P65, N90, P110, N140 and P220 peaks. The response to symmetric/random sequences was indistinguishable from that for random/random sequences up to about 220 msec, after which the response to symmetric patterns became relatively more negative.

And had taken "negative" to mean an emotional reaction rather than whatever it means in the narrow lexicon of the science in this paper. Now, having read more of it, apparently the "negative" part was not about emotional/cognative response at all, and the paper only addresses how quickly we can find symmetry and the brain's functions associated with that.

Well, unfortunately, not much time today either. So, maybe later, time to look more throroughly.
