This file contains the guidelines, which were employed to administer the Self-Assessment Manikin (SAM) [1] and the productivity questionnaire to the participants of the experiment reported in [2]. The guidelines have been written by following the technical manual by Lang et al. [3].
This document will be updated while preparing the camera-ready version of the paper. The camera-ready version of the paper will be made available on Figshare as well (the publisher permits that)
