This note clarifies the relationship between the data described in Rand, Newman, and Wurzbacher (2015) (hereafter RNW) and the data in two related papers, as lags between submission, online publication, and print publication may create confusion for readers. All of the studies in question are follow-ups to Rand, Greene, and Nowak (2012), investigating the effect of time constraint manipulations on cooperation in social dilemmas. RNW specifically explored whether this time constraint effect was altered by social context (partner's group membership in Study 1, cooperative versus competitive framing in Study 2).First, in the time between when RNW was initially submitted and when it ultimately appeared, the data from both studies in RNW were included in a personal meta-analysis of published and unpublished work examining the main effect of time constraints on cooperation . Specifically, RNW Study 1 corresponds to Experiment K in the meta-analysis, and RNW Study 2 corresponds to the pooled results of the two identical-in-design Experiments H and I in the meta-analysis. As RNW had not yet been accepted for publication at the time that the meta-analysis appeared, Experiments H, I, and K were not labeled as corresponding to RNW. 1 Second, following the online publication of RNW in 2014, but prior to the print publication of RNW in 2015, a follow-up paper compared the data from RNW Study 2 with another experiment manipulating competitive frame (Cone & Rand, 2014). This latter paper explicitly indicated that it included a reanalysis of data from RNW, but some readers might be confused by the fact that the follow-up paper has a 2014 publication date, while RNW has a 2015 publication date.Finally, although this does not involve any of the data from RNW, for completeness, it is also noted that Experiment G in the meta-analysis of corresponds to the experiment reported in Cone and Rand (2014); and the subset of data from Experiment L in which the comprehension questions were asked after the cooperation decision are a subset of the data reported in Rand and Kraft-Todd (2014) (additional participants were recruited for that study after the completion of the meta-analysis). Again, neither of these subsequent papers had been accepted for publication at the time that the meta-analysis appeared, and so this correspondence between studies was not indicated in the summary of studies included in the meta-analysis. We also note that various features of the data from the meta-analysis not explored by Rand et al. 1 Note that only participants who completed the demographics questionnaire were included in the analyses of RNW, as these analyses included demographic controls (whereas all participants were included in the meta-analysis). However, interpolating missing values for participants who did not complete the questionnaire and including them in the analyses does not qualitatively alter the conclusions of RNW (there continues to be a significant main effect of time pressure F(1, 878) = 4.42, p = 0.036, and no significant interaction ...
