The ability to flexibly break out of routine behaviors develops gradually and is essential for success in life. We discuss three key developmental transitions toward more flexible behavior. First, children develop an increasing overcome habits by engaging cognitive control response environmental signals. Second, shift from recruiting reactively, as needed the moment, proactively, preparation needing it. Third, relying on signals becoming self-directed. All can be understood terms development...
Obsessive-compulsive disorder (OCD) is a serious and often chronically disabling condition. The current dominant model of OCD focuses on abnormalities in prefrontal-striatal circuits that support executive function (EF). While there growing evidence for EF impairments associated with OCD, results have been inconsistent, making the nature magnitude these controversial. meta-analysis uses random-effects models to synthesize 110 previous studies compared participants healthy control at least...
Executive functions in childhood predict important life outcomes. Thus, there is great interest attempts to improve executive early life. Many interventions are led by trained adults, including structured training activities the lab, and less-structured implemented schools. Such programs have yielded gains children’s externally-driven functioning, where they instructed on what goal-directed actions carry out when. However, it less clear how experiences relate their development of...
Dimensional models of psychopathology that posit a general factor (i.e., p factor), in addition to specific internalizing and externalizing factors, have recently gained prominence. However, the stability these factors specificity with which they are related one another over time (e.g., homotypic or heterotypic continuity) not been investigated. The current study addressed questions. We estimated bifactor models, p, internalizing-specific, externalizing-specific youth caretaker reports...
Whether grocery shopping or choosing words to express a thought, selecting between options can be challenging, especially for people with anxiety. We investigate the neural mechanisms supporting selection during language processing and its breakdown in Our network simulations demonstrate critical role competitive, inhibitory dynamics supported by GABAergic interneurons. As predicted our model, we find that anxiety (associated reduced inhibition) impairs among associated prefrontal cortical...

Evidence suggests that early pubertal timing may operate as a transdiagnostic risk factor (i.e., shared across syndromes of psychopathology) for both genders. The current study examined associations between and dimensional psychopathology, structured different levels three organizational models: 1) DSM-based syndrome model, 2) traditional model internalizing externalizing factors, 3) bifactor (p-factor) which includes general psychopathology well internalizing- externalizing- specific...
Temperament is associated with important outcomes in adolescence, including academic and interpersonal functioning psychopathology. Rothbart's temperament model among the most well-studied supported approaches to adolescent temperament, contains 3 main components: positive emotionality (PE), negative (NE), effortful control (EC). However, latent factor structure of measure for adolescents, Early Adolescent Questionnaire Revised (EATQ-R; Ellis & Rothbart, 2001) has not been definitively...
Abstract When we speak, constantly retrieve and select words for production in the face of multiple possible alternatives. Our ability to respond such underdetermined situations is supported by left ventrolateral prefrontal cortical (VLPFC) regions, but there active debate about whether these regions support (1) selection between competing alternatives, (2) controlled retrieval from semantic memory, or (3) distinct subregions VLPFC (selection mid-VLPFC anterior VLPFC). Each theories has been...
Reduced gray matter volume (GMV) is widely implicated in psychopathology, but scholars have found mostly overlapping areas of GMV reduction across disorders rather than unique neural signatures, potentially due to pervasive comorbidity. reductions may be associated with broader psychopathology dimensions specific disorders. We used an empirically supported bifactor model consisting common and internalizing- externalizing-specific factors evaluate whether latent yield a clearer, more...
Psychopathology is posited to be transdiagnostically linked chronic stress. Yet efforts understand the specificity and directionality of these links have been sparse, ubiquitous comorbidity psychopathology has made seemingly nonspecific between psychological disorders stress difficult interpret. The current study used a latent dimensional bifactor model account for multiwave prospective design disentangle temporal associations longitudinally during critical adolescent period risk reactivity....
Despite overlapping terminology and assumptions that they tap the same constructs, executive function (EF) task performance EF/effortful control (EC) questionnaires have been reported to be only weakly correlated. It is unclear if this reflects true lack of association or methodological limitations. The current study addresses past limitations using a preregistered latent variable approach in community youth sample ( N = 291, age 13-22 years). EF was assessed with well-validated battery...
Poor cognitive control is associated with nearly every mental disorder and has been proposed as a transdiagnostic risk factor for psychopathology, including depression anxiety. What specific mechanisms might cause individuals poor to experience higher levels of psychopathology? The current research tests new process model linking anxiety symptoms via increased dependent stress (i.e., self-generated stressors) subsequent rumination. This was supported across two studies in youth during the...
Depressed individuals exhibit biased attention to negative emotional information. However, much remains unknown about (a) the neurocognitive mechanisms of bias (e.g., qualities information that evoke or functional brain network dynamics may reflect a propensity for attention) and (b) distinctions in types related different dimensions depression ruminative depression). Here, 50 women, clinical was associated with facilitated processing only when such self-descriptive task-relevant. among...
Management of cirrhosis is challenging and has been complicated by the COVID-19 pandemic due to decreased access care, increased psychological distress, alcohol misuse. Recently, The National Institute on Alcohol Abuse Alcoholism broadened definition recovery from use disorder include quality life (QoL) as an indicator recovery. This study examined associations alcohol-associated etiology problematic drinking with liver disease QoL (LDQoL).
Abstract Debates about the function of prefrontal cortex are as old field neuropsychology—often dated to Paul Broca's seminal work. Theories functional organization can be roughly divided into those that describe by process and material. Recent studies posterior, left inferior frontal gyrus (pLIFG) have yielded two quite different interpretations: One hypothesis holds pLIFG plays a domain-specific role in phonological processing, whereas another describes more general cognitive control. In...
Background: Emotion regulation deficits are an outcome and risk factor for both insomnia depression, suggesting that maladaptive emotion might in part explain the bi-directional links between sleep depression. The current study tests this hypothesis during COVID-19 pandemic emerging adult undergraduate students, a high-risk population depression disturbance.Methods: A sample of 154 students completed series online questionnaires bi-weekly on sleep, strategies across eight weeks early days...
Abstract Subjective stress severity appraisals have consistently emerged as better predictors of poor health than stressor exposure, but the reason for this is unclear. may predict one at least two reasons. First, because exposure measures consider all stressors equal, measures—which “weight” by self‐reported severity—might simply not treating being equally impactful. Second, subjective index important individual differences in vulnerability. We tested these possibilities preregistered,...
