b. Test

1. Introduction

The aim of this study is to evaluate the effectiveness of the Nao robot in aiding memory retrieval compared to traditional text-based prompts. We will simulate conditions of early-stage dementia in student participants to test whether interactions with Nao enhance the retrieval of fabricated memories created by us, simulating lost memories typical of individuals with dementia.

2. Method

2.1 Participants

Student volunteers will be divided into two groups: those using the Nao robot for memory retrieval (Test Group) and those using text-based prompts (Control Group).

2.2 Experimental Design

The study employs a between-subjects design comparing memory retrieval success between the Test and Control groups under simulated conditions of early-stage dementia.

2.3 Tasks

Participants will engage in a simulation intended to mimic the memory retrieval challenges faced by individuals with early-stage dementia, using either the Nao robot or text-based prompts to retrieve fabricated memories.

2.4 Measures

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.

2.5 Procedure

Participants will receive an overview of their roles 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.

2.6 Material

Materials include the Nao robot, text prompts based on fabricated memories, memory quizzes, writing materials, and evaluation forms for feedback.
