In the original article, Tsotsos' (1990) concept of an inhibitory surround to the “spotlight of attention” was pointed out but was misattributed to originate from Mounts (2000). It was modeled, before Cutzu & Tsotsos (2003), by Tsotsos et al. (1995). The inhibitory surround is not limited to overt attention but is meant to apply for spatial attention in general. It is reviewed in Carrasco (2011).
The current version of this article reflects these changes.
