Saras Bellur is an Assistant Professor in the Department of Communication at the University of Connecticut. Situated in the broad area of media effects paradigm, her research involves understanding the psychological and physiological effects of interactive media on key communication processes and outcomes. Her work adopts an interdisciplinary approach by combining theories from various disciplines such as media effects, human-computer interaction (HCI), computer-mediated communication (CMC), social cognition and health communication.

Tweeting while watching TV makes show less enjoyable, study finds
It’s harder to enjoy a TV show while tweeting about it, study says
Tribune Publishing print
The UConn Department of Communication found in its study that tweeting reduces viewers' ability to immerse themselves into the TV narrative. "Social media metrics are an important and widely used measure of user engagement, (but) engagement may not necessarily mean enjoyment," Saraswathi Bellur, a UConn assistant professor of communication who co-authored the study, said in an email.
Want to enjoy TV? Then don't live-tweet the shows, study warns

The most significant impact of the two-screen experience was on viewers’ ability to “transport” into the narrative and become immersed in the televised story. “Despite its popularity, live-tweeting has potential pitfalls on audience experience,” said Saraswathi Bellur, assistant professor in communication, who led the research.
When smartphones go to school
“A lot of students tend to think that they are good at multitasking,” or doing more than one thing at a time, says Saraswathi Bellur. She’s a communications researcher at the University of Connecticut (UConn) in Storrs. In fact, she and her colleagues found, multitasking in class “is likely to harm their academic performance.”
Interactive health apps may inspire healthy behaviors, but watch the tone
Penn State News online
Although the back-and-forth feel of a conversation could lead to improved health intentions, a more conversational tone in the messages may make users feel less susceptible to health risks such as obesity, diabetes and heart disease, according to Sundar, who worked with Saraswathi Bellur, assistant professor of communication, University of Connecticut. The study found that when the online tool used short phrases, such as "Mm-hmm" and "Go on" to promote an informal conversational tone, users felt less susceptible to health risks, according to Bellur.
Interactive history beats interactive chat for website engagement
Study participants also did not find a human chat agent to be any better than a chatbot, as long as interaction history was available, according to Sundar, who worked with Saraswathi Bellur, an assistant professor of communication, University of Connecticut

2016 A critical determinant of message interactivity is the presence of contingency, that is, the messages we receive are contingent upon the messages we send, leading to a threaded loop of interdependent messages. While this “conversational ideal” is easily achieved in face-to-face and computer-mediated communications (CMC), imbuing contingency in human-computer interaction (HCI) is a challenge.

2015 This article explicates the concept of user engagement by synthesizing a disparate body of scholarship, and suggests a measurement and a structural model for empirically capturing the meaning and process of user engagement, specifically in the context of interactive media. A second-order confirmatory factor analysis of data from two experiments (N = 263) shows that four attributes—physical interaction, interface assessment, absorption, and digital outreach—together constitute a valid and reliable operationalization of the concept of user engagement. A structural equation model reveals that greater amount of physical interaction with the interface and a more positive assessment of the interface predict cognitive absorption with the content, which in turn is associated with greater behavioral intention to manage and socially distribute the content. In addition, predictive validity tests show that the four subscales are predictors of attitudinal and learning outcomes.

2014 From scrolling and clicking to dragging, flipping, sliding, hovering, and zooming, the wide array of interaction techniques has vastly expanded the range of user actions on an interface. Each of these interaction techniques affords a distinct action. But do these techniques differ in their ability to engage users and contribute to their user experience? Furthermore, do they affect how users view the content and how much they learn from it? We address these questions via two between-subjects laboratory experiments.

2014 Communication research based on social cognition draws heavily from dual process models such as the heuristic-systematic model. Both heuristic and systematic processing are said to be aided by quick rules of thumb or mental shortcuts called heuristics. However, the operationalization of heuristics is quite problematic because their use in decision-making is not directly measured. Scholars claim the operation of specific heuristics in specific situations, based often on clever experimental evidence. We propose a methodological framework that calls for both manipulation and measurement of heuristics in order to offer more direct evidence of their operation. We first review different existing approaches in the literature for operationalizing heuristics. We then discuss our approach and describe the application of moderated mediation to analyze the resulting data. We conclude with a study idea and simulated data that illustrate how our proposed design and analysis framework could be applied in communication research.

2010 Interactivity has become ubiquitous in the digital media landscape. Numerous interactive tools are designed, tested, deployed and evaluated. Yet, we do not have generalizable knowledge about the larger concept of interactivity and its psychological impact on user experience. As a first step toward a theory of interface interactivity, this paper identifies three species of interactivity corresponding to three central elements of communication-source, medium, and message.
