Driving game used in Mather, Gorlick, & Lighthall (2009)

driving game


This 5-minute driving game provides a measure of risky decision making, as participants get points the more they drive during yellow lights, but risk losing all the points if the light turns red while they are driving. It is a modified version of the driving game described in Gardner and Steinberg (2005) that Steinberg and Sheldrick created (see citations below).

Why granting agencies and/or journals should require data archiving

There has been a lot of attention recently to cases of fraud and distortion in published research. In the discussions of possible solutions, little has been said about the potential benefits of mandatory data archiving policies. For instance, if journals required archiving of raw data as supplementary material as part of the process of publishing an article, wouldn't that make authors less likely to massage their data analyses? While the APA and many journals have policies that authors must share data upon request, authors apparently rarely comply with such requests, even when research was published in APA journals. Reluctance to share data has been shown to be related to the number of "apparent" errors in the paper's statistical reporting (such errors often involved p values that should not have been reported as significant but were). If journals (or granting agencies) required public release of data upon publication, researchers would likely be more careful about double checking their results and better about their data management practices, making it possible to easily retrieve data from studies conducted years ago. Making data available for public download should also increase the impact of the findings and benefit the scientific community in many ways.
