    Age-related memory decline is a pressing societal concern. Cognitive training in virtual reality (VR) with social interaction presents a promising approach for digital therapeutics (DTx) to enhance memory function. However, prior studies have primarily employed virtual agents limited to oneway interaction, resulting in restricted social presence. To overcome this limitation, we developed a VR memory training task featuring virtual agents under two interaction conditions: Active vs. Passive interaction, employing the Wizard-of-Oz method. A total of 19 participants conducted the VR memory training task and reported their perceived social presence. Participants in the active interaction condition exhibited a higher level of social presence in perceived message understanding (U = 18.0, p = .028) and displayed delayed reaction time per quiz (U = 18.0, p = .028) compared to those in the passive interaction condition. These findings provide valuable insight for designing future VR DTx, emphasizing the active interaction with virtual agents.
