Dimensional models of obsessive-compulsive (OC) symptoms, as seen in obsessive-compulsive disorder (OCD), are instrumental in explaining the heterogeneity observed in this condition and for informing cutting-edge assessments. Prior structural work in this area finds that OC symptoms cross-load under both Negative Affectivity and Psychoticism traits...

Generalization of conditioned fear is adaptive in some situations but maladaptive when fear excessively generalizes to innocuous stimuli with incidental resemblance to a genuine threat cue. Recently, empirical interest in fear generalization as a transdiagnostic explanatory mechanism underlying anxiety-related disorders has accelerated. As there ar...

Given the increasing use of threat conditioning and generalization for clinical‐translational research efforts, establishing test–retest reliability of these paradigms is necessary. Specifically, it is an empirical question whether the same participant evinces a similar generalization gradient of conditioned responses across two sessions with the i...

Emotional experiences can profoundly impact our conceptual model of the world, modifying how we represent and remember a host of information even indirectly associated with that experienced in the past. Yet, how a new emotional experience infiltrates and spreads across pre-existing semantic knowledge structures (e.g., categories) is unknown. We use...

Theoretical and methodological research on threat conditioning provides important neuroscience-informed approaches to studying fear and anxiety. The threat conditioning framework is at the vanguard of physiological and neurobiological research into core mechanistic symptoms of anxiety-related psychopathology, providing detailed models of neural cir...

Background: Efforts to identify risk and resilience factors for anxiety severity and course during the COVID-19 pandemic have focused primarily on demographic rather than psychological variables. Intolerance of uncertainty (IU), a transdiagnostic risk factor for anxiety, may be a particularly relevant vulnerability factor. Method: N = 641 adults wi...

Psychedelics (hallucinogenic 5-HT2A agonists such as psilocybin) are gaining recognition for their potential to treat a range of conditions, including anxiety-related psychopathology. Despite early promising results, the mechanisms by which psychedelic therapy alleviates anxiety are not well understood. Here, we review neural and cognitive mechanis...

Background: Dysregulated processing of fear and safety has been linked to anxietysymptoms and related traits, e.g., neuroticism, intolerance of uncertainty or negative emotionality. Yet, different studies focus on different aspects of fear acquisition and extinction, outcome measures, and anxiety-related traits, making an integrative approach to th...

Background Fear overgeneralization is a promising pathogenic mechanism of clinical anxiety. A dominant model posits that hippocampal pattern separation failures drive overgeneralization. Hippocampal network–targeted transcranial magnetic stimulation (HNT-TMS) has been shown to strengthen hippocampal-dependent learning/memory processes. However, no...

The organization of the Hierarchical Taxonomy of Psychopathology (HiTOP) model provides unique opportunities to evaluate whether neural risk measures operate as indicators of broader latent liabilities (e.g., externalizing proneness) or narrower expressions (e.g., antisociality and alcohol abuse). Following this approach, the current study recruite...

Our capacity to measure diverse aspects of human biology has developed rapidly in the past decades, but the rate at which these techniques have generated insights into the biological correlates of psychopathology has lagged far behind. The slow progress is partly due to the poor sensitivity, specificity and replicability of many findings in the lit...

Recent research has proposed a relationship between rigid political ideologies and underlying ‘cognitive styles’. However, there remain discrepancies in how both social and cognitive rigidity are defined and measured. Problem-solving, or the ability to generate novel ideas by exploring unusual reasoning paths and challenging rigid perspectives arou...

Fear overgeneralization is a potential pathogenic mechanism of anxiety-related disorders. A dominant model posits that overgeneralization occurs when the hippocampus fails to distinctly encode benign stimuli with insufficient similarity to previously encountered fear cues, triggering excessive retrieval of stored fear representations. This model ha...

As extinction is a context-dependent form of learning, conditioned responses tend to return when the conditioned stimulus (CS) is encountered outside the extinction context, known as contextual renewal. Counterconditioning is a technique that may lead to a more persistent reduction of the conditioned response. However, the effects of aversive-to-ap...

Objective: To examine the role of psychological flexibility as a potential mediator in the relationship between involvement in a guided self-help intervention, Self-Help Plus, and psychological distress in a sample of South Sudanese refugee women living in northern Uganda. Method: We conducted secondary analysis of data from a cluster randomized co...

Generalization of conditioned fear to stimuli resembling a conditioned danger-cue (CS+) is proposed as a key mechanism of clinical anxiety. Given that threat contingencies can be ever changing in day-to-day life, the impact of such changes on generalization is critical to understanding how generalization manifests in the lives of those with and wit...

Our capacity to measure diverse aspects of human biology in vivo has developed rapidly in the past decades, but the rate at which these techniques have generated translatable insights into the biology of psychopathological conditions has lagged far behind. This slow progress is partly due to the poor sensitivity, specificity, and replicability of m...

Several decades of rodent neurobiology research have identified a network of brain regions that support Pavlovian threat conditioning and extinction, focused predominately on the amygdala, hippocampus, and medial prefrontal cortex (mPFC). Surprisingly, functional magnetic resonance imaging (fMRI) studies have shown inconsistent evidence for these r...

Recent research has investigated the relationship between rigid political ideologies and underlying cognitive functions, highlighting discrepancies on how different ‘cognitive styles’ are defined and measured in relation with different shapes of social rigidity. Cognitive rigidity is often operationalized using problem solving which translates into...

Heightened generalization of conditioned fear and avoidance to safe stimuli resembling threat is a key feature of pathological anxiety and might contribute to the increased prevalence of anxiety-related disorders among women. Though rodent studies have documented over-generalized fear in females versus males, analogous work in humans is sparse, and...

Substance use exacerbates psychosis, mania, depression, and poor functioning in people with first episodes of psychosis (FEP) and is associated with poor treatment outcomes, even when it does not reach the level of a formal disorder. Impaired insight and substance use are common issues that may interfere with treatment outcomes among people experie...

Overgeneralization of conditioned fear to safe stimuli that resemble a previously-learned threat-cue is a well-studied correlate of clinical anxiety, yet whether conditioned disgust generalizes remains unknown, as does the extent to which such generalization is associated with disgust-related traits and maladaptive outcomes. The present study addre...

People diagnosed with schizophrenia have been broadly observed to experience deficits in clinical and cognitive insight; however, less is understood about how these deficits are related. One possibility is that these deficits co-occur among people when other deficits in cognition are present, such as in executive function, social cognition, and met...

Laboratory experiments using fear conditioning and extinction protocols help lay the groundwork for designing, testing, and optimizing innovative treatments for anxiety-related disorders. Yet, there is limited basic research on fear conditioning and extinction in obsessive-compulsive disorder (OCD). This is surprising because exposure-based treatme...

Dimensional models of obsessive-compulsive (OC) symptoms, as seen in obsessive-compulsive disorder (OCD), are instrumental in explaining the heterogeneity observed in this condition and have received considerable empirical support. Normative models of personality partially align with OC symptoms; however, maladaptive personality models present a mo...

The Hierarchical Taxonomy of Psychopathology (HiTOP) is an empirical structural model of psychological symptoms formulated to improve the reliability and validity of clinical assessment. Neurobiology can inform assessments of early risk and intervention strategies, and the HiTOP model has greater potential to interface with neurobiological measures...

Generalization of Pavlovian fear to safe stimuli resembling conditioned-danger cues (CS+) is a widely accepted conditioning correlate of clinical anxiety. Though much of the pathogenic influence of such generalization may lie in the associated avoidance, few studies have assessed maladaptive avoidance decisions associated with Pavlovian generalizat...

A central conditioning correlate of clinical anxiety is the over-generalization of Pavlovian fear to safe stimuli resembling conditioned danger cues (CS+). Though much of the pathogenic influence of such generalization may lie in the unnecessary behavioral avoidance it evokes, few studies have examined maladaptive avoidance associated with Pavlovia...

Objective: Heightened generalization of fear from an aversively reinforced conditioned stimulus (CS+, a conditioned danger cue) to resembling stimuli is widely accepted as a pathogenic marker of posttraumatic stress disorder (PTSD). Indeed, a distress response to benign stimuli that "resemble" aspects of the trauma is a central feature of the diso...

Empirically-supported theories posit that individuals with generalized anxiety disorder (GAD) experience uncomfortable affective states and distress in response to perceived emotionally-laden contexts (e.g., interpersonal situations), and are motivated to avoid emotional content through worry. Although we have extensive self-report and physiologica...
