259 259  The hypothesis H0 is that Pepper does not have any effect. In this case, the questionnaires 1 and 2 should give the exact same values for each of the six feelings. However, the graphs and table below show that there is a slight increase regarding positive feelings, and a sligt decrease as well regarding negative feelings.

578 578  * Scope: No. It would be very difficult to generalize the results, since each prototype is built for a special patient. However, if the results conclude that the customized prototypes did improve the well-being of the people, then similar effort to customize Pepper for more patients should produce similar effects.
579 579  * Ecological validity: Yes. Since we compare "without Pepper" (BEFORE) and "with Pepper" (AFTER) in a similar environment (i.e., for everything but Pepper), the results are not dependent on the environment.

575 +We analyzed the participants' moods before and after the interaction with Pepper in order to be able to observe positive and negative changes that are caused by pepper. the results showed that, in general, there is a slight increase in positive moods and a slight decrease in negative moods. The Wilcoxon Signed-rank demonstrated that the only statistically significant change happened for contentness and tiredness based on a p-value threshold of 0.05. This confirms that PwD can potentially benefit from a boost of energy from interacting with Pepper and a general improvement in contentness wich can potentially improve the quality of life of a PwD. It is often the case that PwDs have to perform tasks that are not enjoyable for them such as taking medicines or performing routine activities. In order to analyze the difference in the mood change between people who liked the activity and people who didn't we divided into two groups and performed a Wilcoxon Rank-Sum test. The results show that only the contentness mood shows a statistically significant difference between the two groups which leads us to believe that if an activity is not enjoyable for the PwD Pepper will only decrease his/her tiredness whereas if an activity is enjoyable it will also improve his/her contentness.

590 590  From the system assessment questionnaire, participants quite agree that completing the task was a good accomplishment for them. This supports our claim CL08: the PwD feels accomplished.

592 592  We did not have any question explictly aimed at targeting our claim CL08. However, frustration, annoyance and pressure are often linked to a lack of understanding from the other part. We can combine these with the question about whether Pepper cared about helping the participants, and with our observations during the experiment. When aggregated together, it seems that generally speaking, the participants felt understood. This supports our claim CL08: the PwD feels understood. However, we did notice frustration a couple of times from the participants, because of Pepper's speech recognition system.

597 -All participants, except one who asked to leave the experiment early, finished the whole activity we had prepared for them during the session. This means the participants were able to perform activity steps told by Pepper. This supports our claim CL03: the PwD performs an activity step.

599 -No participant failed to notice Pepper or did not hear what she was saying after the experiment had started. This supports our claim CL01: the PwD becomes aware of Pepper's presence.
