RETRACTED: How birds outperform humans in multi-component behavior
Abstract
This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).
This article has been retracted at the request of the authors. In our Correspondence, we reported evidence leading us to conclude that pigeons are on par with humans when tested with a behavioral task that demands simultaneous processing resources; in particular, we claimed that pigeons show faster responses than humans when sub-tasks are separated with a short STOP-CHANGE delay of 300 ms-the "SCD 300" condition (time advantage of 200 ms). We have subsequently discovered, however, that the MATLAB script that was used for the analysis of reaction times in the pigeon paradigm was wrongly indexed. Therefore, the measured SCD 0 and SCD 300 reaction times from the paradigm were randomly assigned to the corresponding conditions in the analysis script. The subsequent data analysis was thus based on erroneous reaction times of both conditions. The error was detected when a software update made a change in the analysis script necessary. When the correct script is used for the analysis, we find that pigeons and humans show comparable reaction times in both the SCD 0 and SCD 300 condition. The reported time advantage of pigeons compared to humans no longer reaches statistical significance. Thus, in Figure 1C the black bars indicating the reaction times of pigeons are erroneous, while the reaction times of humans (white) remain correct. The same applies to the Supplemental Information: in Figure S2B the black bars indicating the reaction times of pigeons are erroneous, while the reaction times of both human experiments (white and striped) remain correct. We are therefore retracting the paper and apologize to the scientific community for any inconvenience.- Publication:
