1 === 1. Introduction ===
2
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.

5 Recall the image from the [[3. Evaluation Methods>>Main.b\. Human Factors.Measuring Instruments.WebHome]] in the [[1. Foundation>>Main.WebHome]] as in the figure below. 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.

12 ==== 2.1 Participants ====
13
14 As actual PwDs are not available for this research, the participants will consist of several student volunteers. These will be divided into two groups: those using the Nao robot for memory retrieval (the test group) and those using text-based prompts (the control group).

16
17 ==== 2.2 Materials ====
18
19 Materials for the test group include the NAO robot, an OpenAI chatbot running on a mobile phone, and a laptop to control the human-like movements of NAO, as described in the [[prototype>>doc:3\. Evaluation.a\. Prototype.WebHome]]. The control group requires written out text prompts instead.
20 Both groups require a set of fabricated memories, memory quizzes, writing materials, and evaluation forms for feedback. ** **

22
23 ==== 2.3 Measures ====
24
25 Memory retrieval success will be measured using a quiz based on the fabricated memories. Participant feedback and observational notes will also be collected to assess the user experience and interaction effectiveness.
26 We will evaluate the recall and memory-efficacy of both groups and try to relate the given answers to values **(link to evaluation in foundation) **such as autonomy and relatedness.

28 **TODO: More info here once we have the actual evaluation forms (knowledge quiz + emotional questionnaire)**

31 ==== 2.4 Procedure ====
32
33 Participants will receive an overview of their role as a PwD and undergo a session with either Nao or text prompts to retrieve memories. Following the session, they will complete the memory quiz. Feedback will be gathered post-interaction.
34
35 //**Phase 1: Preparation**//
36
37 1. **NAO Robot Setup**: Confirm that Nao is fully operational and our team is equipped to facilitate the interactions by doing a pre-test/trial run with our prototype.
38 1. **Recruitment and Consent**: Recruit a diverse group of student volunteers, ensuring informed consent for participation.
39 1. **Training**: Brief participants on their roles and the concept of simulated memory loss without revealing specific details of the fabricated memories.
40
41 //**Phase 2: Baseline Assessment**//
42
43 1. **Pre-test**: Optionally, assess the students’ ability to recall general information unrelated to the fabricated memories to establish a baseline.
44 1. **Documentation**: Record responses to analyze as a baseline for later comparison.
45
46 //**Phase 3: Memory Recall**//
47
48 1. **Introduction**: Introduce participants in the test group to the NAO robot, explaining its purpose, and provide the control group with their first text-based memory prompt.
49 1. **Simulation**: Conduct sessions where the test group interacts with Nao aiming to recall a set of fabricated memories.
50 1. **Analog control group simulation: **Conduct sessions with an analog encyclopedia with equally complex information on relatives.
51 1. **Memory Quiz**: Following each session, provide a written quiz to both groups based on the memories they were asked to retrieve.
52 1. **Documentation**: Collect the completed quizzes, which will serve as the primary documentation of memory retrieval.
53
54 //**Phase 4: Evaluation**//
55
56 1. **Scoring**: Assess the memory quizzes from both groups to evaluate the quantity and accuracy of retrieved memories.
57 1. **Analysis**: Compare the effectiveness of memory retrieval between the NAO-assisted group and the text-prompt group.
58 1. **Participant Feedback**: Gather feedback from all participants regarding their experience with the memory retrieval process through a questionnaire.
59 1. **Observer Notes**: Collect observations from staff regarding the interaction between participants and the Nao robot or text prompts.
60
61 //**Phase 5: Feedback and Improvement**//
62
63 1. **Participant Reflections**: Review participant feedback for insights into the memory retrieval process and suggestions for improvement.
64 1. **Staff and Observer Insights**: Analyze observations from staff and observers for additional perspectives on the effectiveness and emotional impact of the interactions.
65 1. **Improvement Strategies**: Based on the feedback and results, develop a plan to enhance the memory retrieval capabilities of the Nao robot and the overall test design.

67 == //**Ethical Considerations**// ==
68
69 We commit to high ethical standards, respecting the sensitive nature of simulating dementia conditions, and ensuring the well-being and dignity of all participants throughout the study. To ensure this we present a form containing the ethical considerations to each participant. **TODO: put in link to ethics form?**
