Most organisms facing a choice between multiple stimuli will look repeatedly at them, presumably implementing a comparison process between the items' values. Little is known about the nature of the comparison process in value-based decision-making or about the role of visual fixations in this process. We created a computational model of value-based binary choice in which fixations guide the comparison process and tested it on humans using eye-tracking. We found that the model can quantitatively explain complex relationships between fixation patterns and choices, as well as several fixation-driven decision biases.

In the version of this article initially published, there were symbols dropped from the equations in the second paragraph of the results section. The term θ right should have been θr right in the first equation and the term θ left should have been θr left in the second equation. The error has been corrected in the HTML and PDF versions of the article.Corrigendum: Allosteric potentiation of glycine receptor chloride currents by glutamate In the version of this article initially published, the gender of participants was reversed and the gender of one participant was mislabeled. The correct demographics are 37 female and 21 male participants, with concomitant changes to the values in Table 1 In the version of this article initially published, the labels for NaCl and citric acid were reversed in Figure 2c. The error has been corrected in the HTML and PDF versions of the article.

This tribute outlines some of the major contributions that Stephen H. Schneider made to climate change science and to communication about that science to help a broader audience understand it in an educated manner, and realize that urgent decisions are needed, even with incomplete information. We highlight some of the awards and honors that Dr. Schneider received, and quote from a few already published tributes. We cite some of his publications and provide further sources for readers to learn more about climate science and about Dr. Schneider.
