Rixt Hellinga 18.1 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.

Rixt Hellinga 22.1 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**.

Jean-Paul Smit 3.2 7 The study will investigate the claims on the following questions:
8
Rixt Hellinga 15.1 9 ~1. **Autonomy. **Does the design increase the sense of //autonomy //in a subject?
Jean-Paul Smit 3.3 10
Rixt Hellinga 22.1 11 2. **Relatedness. **Does the design positively affect the subject's //affective //state? Do subjects //like// the system?
Jean-Paul Smit 3.3 12
Rixt Hellinga 22.1 13 3. **Competence. **Is the design //dependable//; is the design accessible enough for the subject to rely on it? Does it feel natural?

Rixt Hellinga 18.1 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.
