Takato Mizuho, Takuji Narumi, Hideaki Kuzuoka

TL;DR
This study explores how using diverse partner avatars in virtual learning environments influences memory acquisition and retention, revealing that varied avatars slow initial learning but do not affect long-term recall compared to constant avatars.
Contribution
It demonstrates the impact of avatar variation on learning dynamics and memory retention, offering insights for designing effective virtual instructor avatars.
Findings
Varied avatars led to slower initial learning.
No significant difference in long-term recall.
Implications for avatar design in virtual education.
Abstract
This study investigates how partner avatar design affects learning and memory when an avatar serves as a lecturer. Based on earlier research on the environmental context dependency of memory, we hypothesize that the use of diverse partner avatars results in a slower learning rate but better memory retention than that of a constant partner avatar. Accordingly, participants were tasked with memorizing Tagalog--Japanese word pairs. On the first day of the experiment, they repeatedly learned the pairs over six sessions from a partner avatar in an immersive virtual environment. One week later, on the second day of the experiment, they underwent a recall test in a real environment. We employed a between-participants design to compare the following conditions: the varied avatar condition, in which each repetition used a different avatar, and the constant avatar condition, in which the same…
