Investigation of Correspondence Between Learner Sensory Processing Sensitivity and Different Avatars in Online Lectures

Characteristics of Highly Sensitive Persons (HSPs), such as “depth of processing,” “overstimulation,” “emotional reactivity and empathy,” and “sensitivity to subtleties,” often present challenges due to their high Sensory Processing Sensitivity (SPS) to environmental stimuli. This study investigates the differences in SPS among learners and the impact of various avatars on video presentations, a medium that has seen increased use due to COVID-19. We surveyed 20 participants who engaged with SDG instructional videos featuring four different avatars. Using the HSPS-J19 self-assessment tool, analysis of their SPS responses revealed a normal distribution of SPS scores, indicating individual differences. Additionally, correlations were found between HSPS-J19 scores and participants' impressions and motivation regarding avatar presentations. Cluster analysis results suggested that the group with a higher tendency towards HSP traits benefited more from appropriate avatar use. Based on these findings, we designed an online lecture support environment that allows for the control of video stimuli. This research explores an underexamined area and aims to enhance online lectures for HSPs, who constitute approximately 15% to 20% of the population. Supporting high SPS learners is particularly significant in the post-COVID-19 era.
