Item Age-related Differences Regarding Spontaneous Reasoning about Social Exclusion(2024) Moore, Sophia V.; Holloway, Hannah J.; Rumberger, Jonquil; Forbes, Marley B.; Kilby, Elena; Killen, MelanieDevelopmental science research has demonstrated age-related changes in children’s use of social and moral reasoning in contexts of intergroup social exclusion. Intergroup social exclusion refers to rejecting someone because of their group identity such as gender, race, and SES. Prior research has identified these patterns by individually interviewing children about their evaluations of different forms of social exclusion. What has not yet been examined is how children spontaneously reason about intergroup social exclusion in classroom-wide discussions. The present study addressed this gap by audio-recording teacher-facilitated classroom discussions that followed the use of an online tool depicting hypothetical intergroup exclusion scenarios once a week for eight weeks. Participants were ethnically and racially diverse 8- to 11-year-old elementary school students attending U.S. public schools in the Mid-Atlantic region, N = 522, N = 30 classrooms. The present study uses a smaller subset of the original sample, N = 6 classrooms. Three reasoning categories were analyzed for this project: moral (fairness, equity), group identity (ingroup preferences, group functioning) and psychological (personal choice). Preliminary analyses suggest age-related differences in children’s reasoning during discussions about race-based exclusion. Fifth graders referenced psychological reasons more often than third graders, who referenced mostly moral reasons. Quantitative analyses will elaborate further on these findings in the poster. These novel findings have broader implications for reducing prejudice and improving intergroup relations in childhood using school-based interventions.Item Maternal Anxiety, Temperament & Brain Morphometry in Infancy(2020) Margolis, Emma; Filippi, Courtney; Ravi, Sanjana; Bracy, Maya; Pine, Daniel; Fox, Nathan; Filippi, Courtney; Fox, NathanMaternal factors (e.g., maternal anxiety) and infant temperament (e.g., distress to novelty) shape children’s social-emotional development. However, we know relatively little about the impact these factors have on infant brain development. This study investigates associations between maternal anxiety, distress to novelty (i.e., negative reactivity) and brain morphometry at 4-months. At 4-months, infants’ temperament was assessed by identifying distress in response to novel stimuli. Mothers completed the Beck Anxiety Inventory (BAI) to measure maternal anxiety. Within 2-weeks, high-resolution structural MRI data were acquired during infants’ natural sleep. MRI data were processed using the iBEAT (Dai et al, 2013) pipeline to obtain subcortical and cortical volume estimates. Regression analyses were conducted to investigate whether infant temperament moderated the relation between maternal anxiety and brain volume at a priori selected regions of interest, controlling for total intracranial volume. Results indicate that there was no significant interaction or main effect of temperament. However, there was a main effect of maternal anxiety in all ROIs tested. Greater maternal anxiety predicted larger hippocampus (β=.417,p<.036), amygdala (β=.429,p<.031), superior frontal gyrus (β=.410,p<.041), middle frontal gyrus (β=.411,p<.039), inferior frontal gyrus (β=.404,p<.039), dorsal anterior cingulate cortex (β=.416,p<.039) and posterior cingulate cortex (β=.407,p<.042). This study provides novel evidence that increased maternal anxiety is linked to differences in child-brain morphometry.Item MRI Processing Pipeline Variability and Infant Brain Morphometry Associations to 4-Month Infant Temperament(2020) Foster, Kayla; Filippi, Courtney; Margolis, Emma; Ravi, Sanjana; Bracy, Maya; Pine, Daniel; Fox, Nathan; Fox, Nathan; Filippi, CourtneyNegative reactive temperament, an infant temperament characterized by fear of novelty, is associated with adolescent amygdala volume (Filippi et al, 2020) and adult prefrontal cortex (PFC) thickness (Schwartz et al, 2010). However, it remains unknown whether these differences in brain morphometry emerge in infancy. Further, evaluating this possibility is a challenge because few pipelines are optimized for processing infant magnetic resonance imaging (MRI) data. Thus, evaluation of available infant MRI processing pipelines is necessary prior to examining associations between negative reactivity and brain morphometry. This study examines (1) which MRI pipeline performs best for 4-month-old infant MRI data and (2) associations between temperament and brain morphometry. Behavioral reactivity was assessed by presenting novel stimuli to infants. High-resolution structural MRI data was acquired a few weeks later. MRI data were processed using the iBEAT (Dai et al, 2013), dHCP (Makropoulos et al, 2018), and CIVET (Ad-Dab’bagh et al., 2006) pipelines to obtain estimates of amygdala and PFC volume. The quality of segmentations of the three pipelines was then assessed. The processing pipelines showed differences in terms of quality of gray/white segmentation and percentage of processing failures. Overall, iBEAT performed the best with the highest percent of useable data. Using the iBEAT output, we examined the associations between infant brain morphometry and reactivity. Results indicated no significant association between amygdala or PFC volume and reactivity.Item Personality Parallels: Parent Neuroticism Predicts Child Social Anxiety(2020) Patel, Harshi; Seddio, Kaylee; Fox, NathanSocial anxiety is one of the most common mental health disorders amongst children and adolescents. There are many external factors associated with social anxiety including negative life events, impaired interactions with other individuals, and maladaptive lifestyle changes. In particular, during adolescence, the consequences of social anxiety can include unsatisfactory relationships with peers and changes in academic responsibility. Previous studies support maternal personality to be associated with the development of mental health disorders in their children. The mother’s personality influences the mother’s interaction with the child and creates the environment in which development occurs. The current study focuses on the influence of parent personality, specifically, neuroticism, on the prevalence of social anxiety in their children. Parents high in neuroticism tend to not be as present in providing support to their children. As well their inability to control emotions leads to unpredictable behavior. In the current study, 243 participants were recruited. Participants were given questionnaires to complete including the NEO-FFI parent report (maternal personality) at 4 years and the SCARED child report (child social anxiety) at 12 and 15 years. An independent samples t-test was performed to look at gender differences in terms of anxiety and parent neuroticism. Results revealed that females reported higher anxiety than males; however, gender was not significant to be a mediator between social anxiety and neuroticism. Neuroticism reported by the mother at 4 years was shown to predict total anxiety on the SCARED when the child was both 12 [F(1, 168)=4.868, p=.029] and 15 years old [F(1, 149)=8.05, p=.005]. This suggests maternal personality is a stable predictor of later childhood anxiety.
