30 -For the experiment, we used a within-subject design. All of the participants interacted with both versions of the robot, with half of the participants interacting with version 1 first and then version 2, and the other half in reverse order. This was done to counter-balance the carryover effects. Snacks were made available for the participants, in case they were prompted and were hungry. They were fully aware of them and some of the questionnaire prompts might have given them an idea of what our experiment is about (or at least that it's related to food), which might have skewed our results.

This was done to counter-balance the carryover effects. Snacks were made available for the participants, in case they were prompted and were hungry. The participants were unaware of the possibility of eating snacks, to prevent disturbing the interaction with the robot. Otherwise the subjects would have been primed for eating, which would have biased the results and hide the effect of the robotic interaction.
