At the request of the authors, The Journal of Neuroscience is retracting “Attending Multiple Items Decreases the Selectivity of Population Responses in Human Primary Visual Cortex” by David E. Anderson, Edward F. Ester, John T. Serences, and Edward Awh, which appeared on pages 9273–9282 of the May 29, 2013 issue. Subsequent to publication, a reanalysis of these data by authors Ester, Awh, and Serences revealed a problem. In the correlational analysis presented in Figure 7, two subjects were omitted without justification and in contradiction to the analytic approach reported in the methods section. Thus, because the paper was published in the context of an inappropriate analysis, all authors have agreed to a retraction.
