1 -To ground the design rationale in practice, the prototype of the NAO for the subject will be evaluated in a formative evaluation with the subject and their caregivers. The evaluation will investigate the process of how interaction with the NAO can alleviate potential symptoms caused by early-stage dementia in subjects.  Three methods of evaluation will be applied to have reliable and accurate results, as Bethel. et al (2020)[1] suggests.
1 +To ground the design rationale in practice, the prototype of the NAO for PwD will be evaluated in a formative evaluation with the PwD (subject) and their caregivers. The evaluation will investigate the process of how interaction with the NAO can alleviate potential symptoms caused by early-stage dementia in PwD.  The study will be conducted focused on the prototype's potential effects, which are based on desired values of self-direction, security and conformity.

3 -The study will focus on the prototype's potential effects, which are based on the desired value of autonomy as a part of self-direction. Before the study, possible confounding variables need to be examined such as the subject's attitude towards robots and the **autonomy, relatedness** and **competence**.
3 +The study will investigate the claims on the following questions:

5 -==== Study design claims ====
5 +~1. Does the design increase the sense of autonomy in PwD?

7 -The study will investigate the claims on the following questions:
7 +2. Does the design have a positive effect on PwD's emotional/affective state?

9 +3. Is the design dependable; do PwD sense that they can rely on it?

13 -3. **Competence. **Is the design //dependable//; is the design accessible enough for the subject to rely on it? Does it feel natural?

16 -For a sample size as small as 20 participants, it is most adequate to apply a within-subjects design (they require fewer participants) [1]. That means there is an approach where every subject is experiencing all of the conditions examined. A within-subjects design might be prone to confounds such as pre-existing notions in the environment. That is why the attitude towards robots and the pre-study sense of affect and autonomy should be examined and evaluated as such. Another confounder variable to look into is the study location and environment.
