61 61  In an optimal scenario where we can test the robot on PwD. We would have measured the number of times a person went out. We would also have measured the effect of the goal and emotion-based motivation on the long-term over the people. Whether it will be less effective over time or not. We would also measure the emotional effect on the caregivers and the functional effect. By the functional effect, we mean whether they indeed have more time to do other tasks or not. It would also have been perfect if we could measure the effect of the walks on the PwD and their health.

The questionnaire is based on a questionnaire in the paper " Measuring acceptance of an assistive social robot: a suggested toolkit " [5]. There are also 5 question at the end that we added ourselves, because we think it fits our experiment.

119 -On average, participants only rejected the robot's persuasion attempts 0.5 times. The participants rated the robot a 2/5 in terms of being scary. They gave a 4/5 for it making life more interesting and it being good to make use of the robot. Questions related to the participant's enjoyment and fascination with the system and the robot were met with ratings between 3.8 and 4.1. The question "I think the staff would like me using the robot" was rated a 4/5 on average. Finally, to the question of whether they would not have gone for a walk if the robot didn't ask them to, the average answer was 3.8/5. All these answers had a standard deviation of less than 1.

123 -Firstly, the Jarque-Bera test [2] was used to check for normality. When the answers to a question weren't normally distributed, the Mann-Whitney U-Test [3] was used. For normally distributed answers, the T-Test [4] was used. These tests used the null hypothesis that there is no significant difference between the two groups. When the calculated probability value (p-value) is less than 0.05, we can reject the null hypothesis and conclude that there is a significant difference between the two groups for the answers to that question.
