Comprehension of an audio versus an audiovisual lecture at 50% time-compression

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. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection
