Professor Juyoen Hur's research lab focuses on the neurobiological underpinnings of anxiety, emotion regulation, and their impact on cognition and behavior. The lab investigates how uncertain threat anticipation, affective states, and individual differences in traits like negative affect shape brain function and cognitive control, with a strong emphasis on translational fMRI methods. Key research directions include the neural circuits of anxiety and fear, the interplay between emotion and cognition—particularly in working memory and perception—and the role of specific brain regions such as the extended amygdala in alcohol-related behaviors. The lab also explores psychological constructs like worry and rumination through advanced psychometric modeling to clarify their distinct and shared mechanisms.

When extreme, anxiety-a state of distress and arousal prototypically evoked by uncertain danger-can be debilitating. Uncertain anticipation is a shared feature of situations that elicit signs and symptoms of anxiety across psychiatric disorders, species, and assays. Despite the profound significance of anxiety for human health and wellbeing, the neurobiology of uncertain-threat anticipation remains unsettled. Leveraging a paradigm adapted from animal research and optimized for fMRI signal decomp
These findings provide a framework for understanding the deleterious consequences of social anxiety in emerging adulthood and set the stage for developing improved intervention strategies.
Although there has been steady progress elucidating the influence of emotion on cognition, it remains unclear precisely when and why emotion impairs or facilitates cognition. The present study investigated the mechanisms involved in the influence of emotion on perception and working memory (WM), using modified 0-back and 2-back tasks, respectively. First, results showed that attentional focus modulated the impact of emotion on perception. Specifically, emotion facilitated perceptual task perform
It remains unclear whether worry and rumination represent the same functional process, or if they are unique constructs. The current study examined the relationship between worry and rumination, focusing on the potential utility of a bi-factor approach as an alternative to “common” vs. “distinctive” approaches. The results indicated that the structural relationship between worry and rumination is best represented by a bi-factor model (compared to single-factor and two-factor models), which is co
Few studies have investigated how attentional control is affected by transient affective states while taking individual differences in affective traits into consideration. In this study, participants completed a color-word Stroop task immediately after undergoing a positive, neutral or negative affective context manipulation (ACM). Behavioral performance was unaffected by any ACM considered in isolation. For individuals high in trait negative affect (NA), performance was impaired by the negative
Alcohol use is common, imposes a staggering burden on public health, and often resists treatment. The central extended amygdala (EAc)-including the bed nucleus of the stria terminalis (BST) and the central nucleus of the amygdala (Ce)-plays a key role in prominent neuroscientific models of alcohol drinking, but the relevance of these regions to acute alcohol consumption in humans remains poorly understood. Using a single-blind, randomized-groups design, multiband fMRI data were acquired from 49
Negative affect is a fundamental dimension of human emotion. When extreme, it contributes to a variety of adverse outcomes, from physical and mental illness to divorce and premature death. Mechanistic work in animals and neuroimaging research in humans and monkeys have begun to reveal the broad contours of the neural circuits governing negative affect, but the relevance of these discoveries to everyday distress remains incompletely understood. Here, we used a combination of approaches-including
ABSTRACT Negative affect is a fundamental dimension of human emotion. When extreme, it contributes to a variety of adverse outcomes—from physical and mental illness to divorce and premature death. Mechanistic work in animals and neuroimaging research in humans and monkeys has begun to reveal the broad contours of the neural circuits governing negative affect, but the relevance of these discoveries to everyday distress remains incompletely understood.

When extreme, anxiety can become debilitating. Anxiety disorders, which often first emerge early in development, are common and challenging to treat, yet the underlying mechanisms have only recently begun to come into focus. Here, we review new insights into the nature and biological bases of dispositional negativity, a fundamental dimension of childhood temperament and adult personality and a prominent risk factor for the development of pediatric and adult anxiety disorders. Converging lines of
Social anxiety-which typically emerges in adolescence-lies on a continuum and, when extreme, can be devastating. Socially anxious individuals are prone to heightened fear, anxiety, and the avoidance of contexts associated with potential social scrutiny. Yet most neuroimaging research has focused on acute social threat. Much less attention has been devoted to understanding the neural systems recruited during the uncertain anticipation of potential encounters with social threat. Here we used a nov
Borsboom et al. confuse biological approaches with extreme biological reductionism and common-cause models of psychopathology. In muddling these concepts, they mistakenly throw the baby out with the bathwater. Here, we highlight recent work underscoring the unique value of clinical and translational neuroscience approaches for understanding the nature and origins of psychopathology and for developing improved intervention strategies.
Social anxiety lies on a continuum, and young adults with elevated symptoms are at risk for developing a range of debilitating psychiatric disorders. Yet, relatively little is known about the factors that govern the hour-by-hour experience and expression of social anxiety in daily life. Here, we used smartphone-based ecological momentary assessment (EMA) to intensively sample emotional experience across different social contexts in the daily lives of 228 young adults selectively recruited to rep
