Abstract Neural substrates of “mind wandering” have been widely reported, yet experiments varied in their contexts and definitions this psychological phenomenon, limiting generalizability. We aimed to develop test the generalizability, specificity, clinical relevance a functional brain network-based marker for well-defined feature mind wandering—stimulus-independent, task-unrelated thought (SITUT). Combining MRI (fMRI) with online experience sampling healthy adults, we defined...
Abstract Left hemisphere damage in adulthood often leads to linguistic deficits, but many cases of early leave processing preserved, and a functional language system can develop the right hemisphere. To explain this apparent equipotentiality two hemispheres for language, some have proposed that is bilateral during development only becomes left-lateralized with age. We examined lateralization using magnetic resonance imaging large pediatric cohorts (total n=273 children ages 4-16; n=107...
Emotional dysregulation symptoms in youth frequently predispose individuals to increased risk for mood disorders and other mental health difficulties. These are also known as a behavioral marker predicting pediatric disorders. The underlying neural mechanism of emotional dysregulation, however, remains unclear. This study used the diffusion tensor imaging (DTI) technique identify anatomically specific variation white-matter microstructure that is associated with severity. Thirty-two children...
Stimulant medications are the main treatment for Attention Deficit Hyperactivity Disorder (ADHD), but overall efficacy in adults has less than a 60% response rate. This study aimed to identify neural and cognitive markers predictive of longitudinal improvement stimulant drug-naïve with ADHD.
Adolescents are particularly attuned to popularity within peer groups, which impacts behaviors such as risk-taking and prosocial behavior. Neurodevelopmental changes orient adolescents toward salient social cues in their environment. We examined whether neural regions that track associated with longitudinal During an fMRI scan, (n=109, Mage=13.59, SD=.59) viewed pictures of popular unpopular classmates based on sociometric nominations from networks. Neural tracking high the dorsomedial...
Social media behaviors increase during adolescence, and quantifiable feedback metrics (e.g., likes, followers) may amplify the value of social status for teens. media's impact on adolescents' daily affect be exacerbated given neurodevelopmental changes that youths' sensitivity to socio-emotional information. This study examines whether neurobiological popularity moderates links between use affect. Adolescents (N = 91, M
Abstract In the current study, we combined sociometric nominations and neuroimaging techniques to examine adolescents’ neural tracking of peers from their real-world social network that varied in preferences popularity. Adolescent participants an entire school district (N = 873) completed peer grade at school, a subset 117, Mage 13.59 years) task which they viewed faces networks. We revealed two processes by adolescents track preference: (1) fusiform face area, important region for early...
Abstract Individuals befriend others who are similar to them. One important source of similarity in relationships is felt emotion. In the present study, we used novel methods assess whether greater multivoxel brain representation affective stimuli was associated with adolescents’ proximity within real-world school-based social networks. We examined dyad-level neural a set regions affect including ventromedial prefrontal cortex (vmPFC), amygdala, insula, and temporal pole. Greater vmPFC...
Abstract Adolescents’ experiences with social media are complex and can impact their mental well-being differently. Our study aimed to understand how neurobiological sensitivities may moderate the association between different depressive symptoms. In a multi-wave study, 80 adolescents (Mage = 13.06, SD .58) took part in an fMRI task designed gauge neural responses when viewing accepted rejected peers within own networks (wave 1). We also collected self-reported measures of positive (digital...
