Abstract
Since students can adjust the speed of online videos by time-compression which is available through common software (Pastore & Ritzhaupt, 2015), it is important to learn at which point compression impacts comprehension. The focus of the study is whether the speaker’s face benefits comprehension during a 50% compressed lecture. Participants listened to a normal lecture or a 50% compressed lecture. Each participant saw an audio and audiovisual lecture, and were eye tracked during the audiovisual lecture. A comprehension test revealed that participants in the compressed lecture group performed better with the face. Eye fixations revealed that participants in the compressed lecture group looked less at the eyes and more at the nose when compared to eye fixations for those that viewed the normal lecture. This study demonstrates that 50% compression affects eye fixations and that the face benefits the listener, but this much compression will still lessen comprehension.
