26		-As there are practical difficulties with conducting the experiment with actual people with dementia due to both time constraints and COVID, our participants' group will consist of peers from other groups and friends, who will act as if they are older people with dementia. We plan to gather around 20 people for our experiments.

30		-We will be using a within-subject design. In the experiment all of the participants will interact with both versions of the robot, with half of the participants interacting with the version 1 first and then version 2, and the other half in reverse order, to counter-balance the carryover effects. Snacks will be made available for the participants, in case they're prompted and they're hungry. The participants will be unaware of the possibility of eating snacks, to prevent disturbing the interaction with the robot. Otherwise the subjects could be primed for eating, which would bias the results and hide the effect of the robotic interaction.

34		-The participant will have to interact with the robot, which is programmed to engage in a lunch discourse. Two versions will be implemented: the first version will ask basic questions about mealtime, mostly acting as a reminder for the PwD to have lunch (alarm clock). The second will be our original implementation of it with the more sophisticated discourse and music.

38		-We plan on measuring the effectiveness of the discourse, both physically and emotionally. Our quantitative measure is whether the person ate the lunch they were supposed to have eaten, and the qualitative measure is the emotions that the PwD experienced before, during, and after the interaction. The qualitative measures will be recorded with a simple questionnaire. Depending on the time of the experiments, we assume that people might also not be hungry enough to be prompted to have something to eat, which might disturb the results. We do plan however to measure whether the robot will remind someone of their hunger and have them eat.
