Episodic memory is known to be environmental context-dependent. The most famous effect is the reinstatement effect: retrieval works better in the same context (SC) as encoding than in a different context (DC). While various environmental context manipulation methods have been examined, we propose a new method using 360-degree video and self-avatar. Comparing the number of words recalled between the SC condition and the DC condition in a within-participant design, there was no reinstatement effect. The result was consistent with the previous works using immersive virtual environments as context. In addition, we found a negative correlation between the presence and the number of words recalled, but it didn’t reach statistical significance. Also, we revealed a time-compression effect of VR only in the condition using self-avatars relevant to virtual environments, not in the condition using a neutral avatar. These findings would be important for the various VR applications.
