Sam and Joey have a new paper on test-retest in threat generalization, published at Psychophysiology. They found that across a relatively short interval, a physiological index of generalization (SCR) was relatively stable. This type of work speaks to an increased push towards psychometric validation of threat conditioning tasks.

Big news: The Dunsmoor Lab’s second-ever graduate student, Nicole Keller, recently became a doctor! Her (very impressive) dissertation discussed her work on the influence of counterconditioning on return of fear. Though we are sad to see her go, we look forward to seeing all that she accomplishes with her shiny new PhD. We will miss you, Nicole!

We have a new paper in Neuron out this month by Joey Dunsmoor, Josh Cisler, Greg Fonzo, Suzannah Creech, and Charles Nemeroff entitled “Laboratory models of posttraumatic stress disorder: The elusive bridge to translation.” In this paper, Joey and colleagues from UT Austin describe the shortcomings of popular laboratory animal models of PTSD, such as Pavlovian fear conditioning, and prescribe concrete ideas for improving these models to better understand the complexity of PTSD symptoms in laboratory research in humans.

We have a new paper out soon in Trends in Cognitive Sciences by Joey Dunsmoor, Vishnu Murty, David Clewett, Liz Phelps, and Lila Davachi, entitled “Tag-and-capture: How salient experiences target and rescue nearby events in memory.” In this paper, Joey and his colleagues review emerging research on the enhancing property of salient experiences for rescuing memory for weak events encoded in a critical time window before or after a salient experience.

In our recent meta-analysis published in Neuropsychopharmacology, we found that across behavioral studies, conditioned fear generalization is significantly stronger than those found in meta-analyses of more simple differential conditioning paradigms, providing additional support for the use of generalization paradigms in the study of pathological anxiety.

Huge congratulations to the Dunsmoor Lab’s first graduate student, Gus Hennings, for defending his dissertation! He is now officially Dr. Gus. He will begin his postdoctoral studies this Summer in the lab of Dr. Ken Norman at Princeton University, where he will use real-time fMRI to continue studying memory. The lab is so proud and we can’t wait to see all that he accomplishes!

Sam is honored to receive a 2-year NRSA F32 personal fellowship from the National Institute of Mental Health, titled “Neurobehavioral Mechanisms of Higher-Order and Conceptual Fear and Avoidance Generalization in Anxiety Psychopathology” (mentors: Dunsmoor and Nemeroff). This fellowship includes training in multivariate fMRI analyses in service of two studies of higher-order generalization processes through which networks of abstract or indirect fear associations develop and spread in PTSD and covary with dimensional anxiety traits.
December 4, 2021
In our new paper published in Current Biology, we explore how fear and extinction memories are organized in the human brain. Notably, we observed that healthy adults’ and adults with PTSD’s brains store memories of fear and extinction differently, which may indicate a physical biomarker for the source of fear generalization in adults with PTSD.
November 30, 2021
In our new review published in Neuroscience and Biobehavioral Reviews, we systematically review the evidence for fear conditioning deficits in obsessive-compulsive disorder, a first for the field. Extinction deficits are the most strongly supported, but new and more complex conditioning work is needed in this area.
August 10, 2021
As of July 20, we have a new lab manager/research associate in the lab. Welcome Sophia! We are looking forward to a great year of research!

According to our new research published in Frontiers in Communication, fear in response to COVID-19 is related to people thinking more rigidly and makes it harder for them to recognize misinformation and more likely to spread it.
January 21, 2021
In our new paper published in Neuropsychologia, we investigate how episodic mental context processes guide the retrieval of fear extinction. Additionally, we show that this process is dysregulated in individuals with PTSD symptoms.

Congratulations to Gus, who recently received a 2-year NRSA F31 personal fellowship from the National Institute of Mental Health!

New paper in Neuropyschopharmacology explores how PTSD patients generalize conditioned fear across semantically-related categories. Results help us understand how fear spreads across related concepts in PTSD!
March 31st, 2020
New paper from our lab on the effects of reward on implicit and explicit fear memory. Our results provide novel evidence that aversive-to-appetitive counterconditioning, as compared to extinction, strengthens memory for items directly associated with a positive outcome and diminishes fear relapse.
December 19th, 2019
In our new review paper we explore a technique that has been largely overlooked for the past few decades: counterconditioning. We describe neurobiological and neuroimaging research in this area and we detail whether counterconditioning is any more effective than standard extinction at preventing relapse of the originally learned behavior. Read to find out!

Joey is honored to receive a CAREER Award from the National Science Foundation. The grant is entitled “Implications of a neurobiological model of memory for education: how novelty exposure transforms poor learning into durable memories.”
Here’s a brief summary: There are remarkable findings in laboratory animals that mere exposure to novelty has memory enhancing effects, as long as novelty exposure is properly timed to coincide with weak learning within a critical time window (de Carvalho Myskiw et al., 2013; Moncada et al., 2015; Viola et al., 2014; Wang et al., 2010). A greater understanding for how to precisely apply novelty exposure to boost poor learning holds a number of exciting implications for human memory, including applied strategies to improve education, therapy, and memory in daily life. For example, a straightforward application is to induce novelty exposure within a critical time window before or after learning so as to bolster retention of the learned material.
The lab is super excited to work on these projects. Contact us if you’re interested in joining the team!
