Although the authors do not report effect sizes directly it seems that, in many cases, walking shifted the distribution at least one standard deviation in a direction of higher creativity (that is a lot).
At the same time I wish the results were reported better, in many cases they do not even report the mean and standard deviation of different experimental groups.
We are trying to do something like this with large-scale studies for English and Dutch. As it is very related to the problem I will allow myself to share the links: http://vocabulary.ugent.be http://woordentest.ugent.be
