Competing Interests

The author has the following conflicts. The present Formal Comment challenges a reanalysis presented by Brown et al. [1], which was critical of an empirical report by the current author and her colleagues that appeared in PLOS ONE in 2015 [2]. That 2015 empirical report offered new data that challenged critical statements made previously by Brown et al. [5] regarding a 2013 empirical report by the current author and her colleagues that appeared in the Proceedings of the National Academies of Science, USA [4].
