After publication of the original article [1], it came to the publisher's attention that a number of corrections submitted by the author during proofing had not been implemented. Upon investigation it transpired that an error in the production process resulted in these further corrections being overlooked. The overlooked changes were solely to correct typos through the article. For example, in the Background section of the abstract, "thelateralizing" should have read "the lateralizing". As such, the changes do not affect the scientific content of the article. The original article has now been updated to rectify the missed corrections requested by the author.
