3 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**.

7 -The study will investigate the claims on the following questions:
7 +== //**Study design variables**// ==

9 -~1. **Autonomy. **Does the design increase the sense of //autonomy //in a PwD?
9 +The study will hypothesize on the following variables with regards to the system:

11 -2. **Relatedness. **Does the design positively affect the PwD's //affective //state? Do PwDs //like// the system?
12 12  
13 -3. **Competence. **Is the design //dependable//; is the design accessible enough for the PwD to rely on it? Does it feel natural?
12 +1. **Autonomy. **Does the design increase the sense of //autonomy //in a PwD?
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?

21 +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.

Another confounder variable to look into is the study location and environment.

28 +For autonomy, a validated survey tool is the self-care score as used in the Diabetes research paper of PAL by Neerincx et al.

30 +Affect can be measured with a button ([[http:~~/~~/ii.tudelft.nl/~~~~joostb/affectbutton_version2_original.html>>url:http://ii.tudelft.nl/~~joostb/affectbutton_version2_original.html]]) that takes less than a minute. It will be used for both pre-experiment and post-experiment evaluation.
31 +
32 +For Attitude towards robots, we build upon the works of [reference] and create a set of two 1-minute questions.
33 +
34 +A well-suited tool for Memory self-efficacy is the Rivermead behavioural memory test [reference]. We adopt it to fit to the ecological validity and domain of interest in our study.
