News Blotter


February, 2024 Journal of Media Psychology

Every Friday after work you go out with coworkers for a few drinks, and invariable end up posting a few pictures of your Friday Funzies to Instagram. Can the way you depict yourself in relation to alcohol actually change your relationship with alcohol? A registered report by Dr. Femke Geusens, myself, and Dr. Kathleen Beullens drew on identity shift theory to answer this question. Perhaps fortunately, neither posting pictures of alcohol or being social with alcohol affected participants' intention to drink in the future.


January, 2024 Media Psychology

It is pretty well established that recent social media posts can affect employers' perceptions of an applicant; but what about when employers find those posts you made years ago? New research by brilliant graduate scholars Mary C. Katreeb (now a PhD student at Arizona State) and Ertemisa P. Godinez (now a talent specialist for a financial services firm) looks at the effect of post temporality on current impressions. The good news is that older posts seem to impact perceptions of the 'now' you less than more recent posts.


November, 2023 Human Communication & Technology

Do sponsored posts tell us as much about a target's offline self as either self-statements or third party reviews? New research by a group of graduate scholars tells us that influencers may be better than an organization's own claims; but aren't as good as true reviewers from unknowns. This paper was the output of my Fall 2022 COM418 course, and demonstrates how well the enrolled scholars mastered the warranting construct.


Summer, 2021 CMC Textbook

A long while in the making, you can now pre-order Computer-mediated communication, my new textbook for undergraduate scholars, is now available. The book focuses on both theories and applications of mediated communication, presenting classic theories in contemporary environments. Chapters address interpersonal, group, organizational, and political communication online, as well as social media, CMC for education and persuasion, and other contemporary topics. Instructor supplements forthcoming, including test bank and sample assignments.



A Little About Caleb


Born at an early age just outside Flint, Michigan, Caleb T. Carr is a Professor of Communication, and sometimes refers to himself in the third person. His research primarily explores computer-mediated communication as it converges organizational and interpersonal phenomena, decision making and the development and presentation of identity online; he also cares about your interests. In addition to scholarly pursuits, he has performed in London’s West End, water skied with alligators, and yodeled in the Alps. His career path has allowed him to pursue his passions of research, teaching, and skiing; though he sometimes restructures those priorities. He takes his cheesesteaks “with.”


A Little More About Caleb's Research


Although he has had training in qualitative analysis and rhetorical criticism, Caleb is epistemologically a quantitative researcher, who typically uses experiments and surveys to answer research questions. His research focuses on how individuals and organizations are blurring the line between personal and professional through technology. As effective lenses through which to explore these issues, Caleb's research has often used online discussions and group decision tasks, the popular online multiplayer game World of Warcraft, and online communities in his experiments. In survey research, interesting data is often authored from human resource practitioners and managers in organizations.

Yet More About Caleb's Teaching


Though an avid and involved researcher, Caleb also enjoys teaching, particularly the opportunity to take material from the lab straight into the classroom to keep students abreast of the latest developments in their discipline. Caleb has taught many courses in several departments to an equally diverse array of students. With teaching experience in Business, Communication, and Telecommunication, he has taught to both traditional (i.e., undergraduates living on-campus) and non-traditional (i.e., returning, older, and telecommuter) students in both on-ground and online courses.
