Abstract
Reminders are often used to support people's prospective memory (PM). Research in Human-Robot Interaction (HRI) has primarily focused on when and how a robot reminder could better help humans, while the content of the reminder itself has received less systematic attention. This research investigates whether the content of a robot-delivered reminder affects users' subjective experience. Specifically, it compares episode-grounded reminders, which reference the situation in which the PM intention was originally formed, with reminders that omit this context, measuring effects on confidence in remembering, trust in the robot, and perceived usefulness. A between-subjects experiment (N = 21) was conducted on a browser-based 2D platform that uses a cooking scenario to impose concurrent cognitive demand with four PM tasks. Participants received either episode-grounded (EE1) or plain (EE0) reminders. Results showed that EE1 reminders were associated with significantly higher confidence compared to EE0 reminders (p = .034 after correction for multiple comparisons); trust and perceived usefulness did not differ between conditions. These findings contribute a theoretically grounded design procedure and a reusable experimental protocol for episode-grounded reminder content, and suggest that grounding reminders in episode context may shape users' confidence in remembering.
