The proportional choice data were taken from a publicly available dataset described by Steingroever et al. (2015), and available at: http://dx.doi.org/10.5334/jopd.ak
The data were imported into R, and then analysed using the script [powercontoursIGTpar.R][1]
This script generates [Figure3.pdf][2]
Paths in the script will require updating to reflect local directory structures.
