Subject: [AUDITORY] last call for pupillometry beta testers From: Samuel Mehr <sam@xxxxxxxx> Date: Thu, 2 Jul 2020 15:54:00 +1200--000000000000f5e4ca05a96d5d04 Content-Type: text/plain; charset="UTF-8" Dear AUDITORY, thanks much to all who have expressed their interest in joining the private beta of our video-based pupillometry software. We've had 45 labs sign up so far (!) from all over the world. This is just to let others know that we will continue accepting letters at musiclab+pupils@xxxxxxxx until Monday night EDT; all are welcome and if you'd like to join, please submit one by then. All the details are copied below. best, Sam -- Samuel Mehr Department of Psychology Harvard University *Be a citizen scientist at themusiclab.org <https://themusiclab.org/>!* My lab has been working on new software for automatic post-hoc pupillometry > measurement that takes as input a video of a study participant and produces > measures of relative changes in pupil size over the course of the video. > We've already made an MTurk tool for manual annotation of pupil size, which > is used for a secondary analysis in this preprint > https://psyarxiv.com/xcj52 (in infants, pupils are less dilated during > soothing lullabies than exciting other songs). An automatic version, where > MTurk workers are replaced with a neural net, is giving promising results. > We are applying for some NSF funding to build a fully automatic version, > with an eye toward making the method feasible with webcam videos of the > sort that "participate-from-home" studies will produce. It should work in > adult, child, and infant participants. As part of the proposal, we plan to > release a private beta version of the software to a group of labs who will > try out the method on their own participant videos. > I'm writing to ask if you would be interested in being a beta tester, and > if so, to ask that you submit a Letter of Collaboration that we can include > in our NSF application. > The only expectation of beta testers is to do a pupillometry analysis of > your participant videos (in any type of experiment) using the beta software > and to let us know how it went: we would just ask for some feedback on the > software so that we can improve it, and possibly some summary statistics > describing the results (e.g., main effect size; comparison to other > measures you happened to use, like psychophysiology, or convergent validity > with pupillometry measured with an eye tracker). > *If you are interested in being a beta tester, please send an NSF-style > Letter of Collaboration to musiclab+pupils@xxxxxxxx > <musiclab%2Bpupils@xxxxxxxx>*.
