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.
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.

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**.

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.
