As so many of you are doing web experiments or interested in web experiments, I thought I'd share our recent paper comparing data from web and lab samples for different measures including face and emotion recognition:
Essentially we find comparable means, standard deviations, and internal reliability for web and lab-based samples on these tests. We hope it'll be a resource for other researchers who are thinking about using web-based methods and those who want to address reviewer skepticism about web methods for face recognition research.
Please let me know if you have questions.
