24.1 | 1 | To ground the design rationale in practice, the prototype of the NAO for the PwD will be evaluated in a formative evaluation with the PwD 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. Three methods of evaluation will be applied to have reliable and accurate results, as Bethel. et al (2020)[1] suggests. |

24.1 | 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 PwD's attitude towards robots and the **autonomy, relatedness** and **competence**. |

| 13 | 1. **Relatedness. **Does the design positively affect the PwD's //affective //state? | ||
| 14 | 11. **Affect**. How do participants feel about using the robot in this state? | ||
| 15 | 11. **Attitude towards Technology**. How do people think about using technology? Are they biased towards the robot before the study? | ||
| 16 | 1. **Competence. **Is the design //competent//; is the design capable enough for the PwD to rely on it? | ||
| 17 | 11. **Memory self-efficacy **(pre-study) How good are participants at remembering information? | ||
| 18 | 11. **Memory recall **(post-study) Can the participant accurately retrieve information through the robot? | ||

37.1 | 22 | 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 PwD 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. |
