Abstract

This study delves into the effects of increased video playback speed on memory retention among undergraduate students in a group learning context. Analyzing data from 138 participants watching a psychology lecture at either 1.5x or 2x speed, along with demographic factors like age, GPA, and confidence ratings, the research found no significant difference in quiz scores between the two-speed conditions. However, participants in the 2x speed condition expressed lower confidence than those in the 1.5x speed condition. Notably, a higher GPA correlated with better quiz performance, emphasizing the role of academic achievement in memory retention. While faster video speeds didn't impair memory, they influenced confidence levels and gender differences, adding a nuanced level to this finding. These findings provide insights for optimizing video-based instruction in educational settings, considering individual characteristics and potential effects on student experience.

Comments

I received the Len Stern Grant for this project during the 2023-2024 school year. Additionally, my presentation has been chosen by the Rocky Mountain Psychological Association for the 2024 conference in Denver, Colorado. I am set to present at a symposium on April 12th in Denver, and I am excited about the chance to also share my research with the Eastern community.
