3 3  This study aims to evaluate the effectiveness of the Nao robot in aiding memory retrieval through the use of a between-subjects design with a test group and a control group. We will simulate conditions of early-stage dementia in student participants to test whether interactions with Nao enhance the retrieval of memories fabricated created by us, mimicking lost memories typical of individuals with dementia.

The first two concepts, that of Autonomy and Relatedness and the memory self-efficacy, will be tested by using validated surveys. The memory recall will be tested by a custom survey that was catered to be used with the robot in the domain of interest, that is of using the NAO as an encyclopedia for recalling familiar people.

68 -Twenty University students participated in the controlled experiment (M= 45%, F=55%). After gaining consent through the consent form, all participants were briefed to act as if experiencing the interaction from the viewpoint of a PwD. From the sample, half were asked to interact with the NAO and half were only using a voice-based version of the encyclopedia prototype.

79 -**Sample Group and Size impact validity of the study**
80 -
81 -The ecological validity of the study is impacted by the fact that there were no PwD in our sample.The scope of the experiment was limited to TU Delft University students. That means that future research may benefit from a closer approach to an experiment which is closer to the experience of PwD. Moreover, the controlled experiment was restricted to a cohort of 20 participants, underscoring the potential for enhancing result validity through the utilization of a larger sample size

86 86  //Ambiguities in the evaluation briefing has led to several aspects in the results that might misrepresent the participants' gathered knowledge. Points were awarded to the participant for certain key descriptors, each family member's role, occupation, likes, dislikes and so on. Of course, this wasn't known to the participant, so they might have omitted descriptors they deemed less important or trivial and therefore scored worse, even though they'd heard and remembered them.//
