As part of the Motivation Science special issue on psychological reactance, Dr. Rosenberg and Dr. Siegel published an introduction and overview of the theory and research in the volume. The paper summarizes the contributions of the nine papers in the special issue, placing them in each of the five overlapping waves of reactance research.

HAM Lab held a lovely celebration to cap off another amazing year. Three incredible HAM Lab RAs graduated in May – Chris, Kaylee, and Sarah. I am so proud of all of you and also very sad to see you go!
The entire HAM Lab – led by undergrads Chris, Kaylee, Madelyn, and Sarah – presented two posters at the annual meeting of the Western Psychological Association in Las Vegas. The first poster, with Jillian in the lead, presented data from a weeklong daily diary study investigating the qualitative aspects of people's goal pursuit and the goal expectation violations that naturally occur as a part of daily life. The second poster examined the influence of mindfulness on psychological reactance.

Along with Dr. Jason T. Siegel, of Claremont Graduate University, Dr. Rosenberg published a paper in the journal Motivation Science.

The result is that reactance is magnified! The paper is here.

December 2022
Chronicle reporter Claire Haor interviewed Dr. Rosenberg for an article on COVID fatigue – even in the highly cooperative Bay Area. The article quoted Dr. Rosenberg talking about people's limited self-regulation after 3+ years of mitigation behavior, as well as the need to capitalize on "fleeting" motivation to get boosted.
Guardian writer Matthew Cantor interviewed Dr. Rosenberg for an article on the ongoing "tripledemic" – COVID, the flu, and RSV – and the role of masking. Dr. Rosenberg discussed the role of softened messages, as opposed to mandates, in encouraging mask-wearing at this juncture.
October 2022
KCBS reporter Jeffrey Schaub interviewed Dr. Rosenberg for a brief radio segment on the lackluster uptake of COVID booster shots. "It takes place in an urgent care center, or a pharmacy – somewhere that folks visit quite often," said Rosenberg. "It's all about providing people with an opportunity right then and there."
A longer version of the Marin IJ piece by Drs. Rosenberg and Siegel appeared in a recent newsletter from Dr. Katelyn Jetelina, aka Your Local Epidemiologist, outlining how to use the IIFF Model to raise lagging bivalent booster rates. The extra eyes on this work will hopefully raise the profile of social scientists in fighting the ongoing waves of the COVID pandemic.
September 2022
For the second time, Kristen Sze of ABC7 News interviewed Dr. Rosenberg about the COVID pandemic. Luckily, in this live interview, no cat showed up – but Dr. Rosenberg discussed the Marin IJ piece about increasing booster uptake using the IIFF Model.
Dr. Rosenberg authored an op-ed piece in the Marin Independent Journal using an approach from the research of Dr. Jason T. Siegel, his coauthor, to outline an evidence-based campaign for persuading people to get bivalent COVID-19 booster shots. The approach, an homage to the IIFF model, relies on the assumption that folks who have received two, three, or four jabs already are willing – but not necessarily motivated – to get another.
A long awaited chapter, coauthored by Dr. Rosenberg and two colleagues from Claremont Graduate University (Alex Marshburn, MA and Jason T. Siegel, Ph.D.), came out this month! The chapter, published in the Oxford Research Encyclopedia of Psychology, traces the development of the field of persuasive communication through the lens of Hovland and colleagues' (1953) seminal text.

A piece in the LA Times about the removal of California mask mandates quoted Dr. Rosenberg. In part, the article read, "The path through endemicity isn’t all negative. That research just presented by Rosenberg was focused on what happens when you hit anti-maskers with “soft” messaging instead of mandates. Turns out that feels a bit like freedom to them, Rosenberg said, cutting down on the 'super-duper resistance.'”
Dr. Rosenberg was selected to give a 10-minute presentation during the preconference meeting for Motivation Science prior to the annual Society for Personality and Social Psychology conference in San Francisco, CA.

June 2021
Beginning this summer, we are starting a new collaboration with Dr. Richard Lopez and his REACH Lab, based at Bard College; and Dr. Jason T. Siegel of Claremont Graduate University. The focus of this research will be on expectation disruption theory (EDT; formerly known as GDT, see Rosenberg & Siegel, 2015). More details to come!
April 2021
A new paper, coauthored by Dr. Jason T. Siegel and Dr. Rosenberg, was just published online in the journal Current Psychology. The article, titled, "Threatening uncertainty and psychological reactance: are freedom threats always noxious?" examines the influence of uncertainty on people's reactions to freedom-threatening messages. A main takeaway: people in a state of uncertainty experience less psychological reactance than those in a state of certainty.
