Note: the performance of video-based learning includes three indexes, learning outcome, subjective cognitive load and learning satisfaction. And 84 participants (age: M = 21.18, SD = 1.95) were randomly assigned to either the bullet-screen or bullet-screen-free video learning groups based on their cognitive styles
