Reports an error in "ViSA: A Neurodynamic Model for Visuo-Spatial Working Memory, Attentional Blink, and Conscious Access" by Luca Simione, Antonino Raffone, Gezinus Wolters, Paola Salmas, Chie Nakatani, Marta Olivetti Belardinelli and Cees van Leeuwen ( Psychological Review, Advanced Online Publication, Jul 23, 2012, np). The article was published online missing the link to the supplemental materials. The link to the supplemental materials is provided in the erratum. (The following abstract of the original article appeared in record 2012-19411-001.) Two separate lines of study have clarified the role of selectivity in conscious access to visual information. Both involve presenting multiple targets and distracters: one simultaneously in a spatially distributed fashion, the other sequentially at a single location. To understand their findings in a unified framework, we propose a neurodynamic model for Visual Selection and Awareness (ViSA). ViSA supports the view that neural representations for conscious access and visuo-spatial working memory are globally distributed and are based on recurrent interactions between perceptual and access control processors. Its flexible global workspace mechanisms enable a unitary account of a broad range of effects: It accounts for the limited storage capacity of visuo-spatial working memory, attentional cueing, and efficient selection with multi-object displays, as well as for the attentional blink and associated sparing and masking effects. In particular, the speed of consolidation for storage in visuo-spatial working memory in ViSa is not fixed but depends adaptively on the input and recurrent signaling. Slowing down of consolidation due to weak bottom-up and recurrent input as a result of brief presentation and masking leads to the attentional blink. Thus, ViSA goes beyond earlier 2-stage and neuronal global workspace accounts of conscious processing limitations. (PsycINFO Database Record (c) 2012 APA, all rights reserved)
