Synchronized eye movements predict test scores in online video education

Proceedings of the National Academy of Sciences, Journal Year: 2021, Volume and Issue: 118(5)

Published: Jan. 28, 2021

Significance Education is increasingly delivered online, but are students actually paying attention? Here we demonstrate that efficacy of video instruction can be assessed remotely with standard web cameras. Specifically, show attentive have similar eye movements when watching instructional videos and synchronization a good predictor individual learning performance. Measuring while preserving privacy, as shown here, has the potential to make online education adaptive attentional state advance mechanistic studies on different formats. Attention become commodity online. With increasing abundance content, remote sensing attention at scale may relevant beyond education, including entertainment, advertising, politics.

Distracted by a talking head? An eye tracking study on the effects of instructor presence in learning videos with animated graphic slides

Learning and Instruction, Journal Year: 2024, Volume and Issue: 91, P. 101878 - 101878

Published: Jan. 28, 2024

There are still unanswered questions concerning the optimal design of educational videos, for instance with regard to visibility a talking head next learning content. Although visible heads in videos may stimulate deeper processing, they can also distract from visual The current eye tracking study investigated how presented stepwise appearing (i.e., animated) graphic-based content affected learners' movements, learning, and ratings (e.g., social presence). Ninety-six university students participated experiment. We used within-subjects vary whether was present short narrated slides. Our results revealed that both reduced fixation duration overall number fixations newly Further, time first delayed by head. However, did not affect outcomes (knowledge test picture recognition task performance) there no mediation Additionally, learners indicated higher presence including head, but we observed differences perceived satisfaction, difficulty, invested mental effort due strongly influenced movements reducing cause any losses. discuss implications limitations findings view future research.

Onscreen presence of instructors in video lectures affects learners’ neural synchrony and visual attention during multimedia learning

Proceedings of the National Academy of Sciences, Journal Year: 2024, Volume and Issue: 121(12)

Published: March 11, 2024

COVID-19 forced students to rely on online learning using multimedia tools, and continues impact education beyond the pandemic. In this study, we combined behavioral, eye-tracking, neuroimaging paradigms identify processes outcomes. College viewed four video lectures including slides with either an onscreen human instructor, animated or no instructor. Brain activity was recorded via fMRI, visual attention outcome assessed post-tests. Onscreen presence of compared instructor presence, resulted in superior post-test performance, less slide, more synchronized eye movements during learning, higher neural synchronization cortical networks associated socio-emotional processing working memory. Individual variation cognitive abilities intersubject revealed different levels conditions. The instructor-present condition evoked increased synchronization, likely reflecting extra demands attentional control, memory engagement, processing. Although instructors led comparable outcomes, effects were due dynamic interplay information vs. distraction. These findings reflect a benefit–cost trade-off where is enhanced only when benefits motivated by social outweigh costs brought about concurrent distraction unrelated learning.

Exploring the Communicative Effectiveness of Visual and Text Elements in Short Videos

Business and Professional Communication Quarterly, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 20, 2025

Given the prioritization of video format in social networks, interest scholars and managers elements that determine their effectiveness has increased. This article analyzes image type (product vs. people) written text’s role message reinforcement. Three studies are carried out combining conscious unconscious responses. We contribute to visual rhetoric literature, affirming image-based videos more liked shared versus short based on text. Specifically, images related content than a person explains content, although attention is greater when appears. As for overwritten text, it favors willingness share videos, but reduces likeability with content. Additionally, response through electrodermal activity shows persons text achieve emotional activation avoid wanes. These findings aid designing effective brands individuals use media communicate.

A Systematic review of instructor presence in instructional videos: Effects on learning and affect

Computers and Education Open, Journal Year: 2021, Volume and Issue: 2, P. 100059 - 100059

Published: Nov. 12, 2021

In recent years the use of instructional videos with on-screen instructors has gained global popularity in college classrooms and across private industries. However, it is not clear if including instructor an video provides any benefit to learners, research area been synthesized. We conducted a systematic review examine impact on learning affect. Twelve studies met inclusion criteria were analyzed. Our analysis results showed no consistent, compelling evidence that should be included videos, as non-significant mixed pervasive throughout literature. we also did find convincing leave out video, some found learners more satisfied when was visually-present. explore these depth, highlight need for area, outline potentially productive frameworks lines research.
