Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 66-10 (October 2025) . - p.1551-1562 Titre : Combined effects of prenatal ozone exposure and school/neighborhood environments on youth brain, cognition, and psychotic-like experiences Type de document : texte imprimé Auteurs : Tianjiao KONG, Auteur ; Yumeng YANG, Auteur ; Feng JI, Auteur ; Jia LIU, Auteur ; Ran LIU, Auteur ; Liang LUO, Auteur Article en page(s) : p.1551-1562 Langues : Anglais (eng) Mots-clés : Prenatal ozone exposure  psychosocial environments  combined effects  limbic system development  cognition  psychotic-like experiences Index. décimale : PER Périodiques Résumé : Background Humans are inevitably exposed to multiple physical and social environmental risk factors, potentially contributing to psychiatric problems and cognitive deficits; however, the combined effects of prenatal air pollution and psychosocial environments on youth remain unclear. This longitudinal study aimed to examine how prenatal ozone exposure interacts with psychosocial environments at 9 10 years to affect adolescent limbic system development, cognition, and psychotic-like experiences (PLEs) at 11 13 years. Methods We analyzed data from 6,778 participants in the Adolescent Brain Cognitive Development (ABCD) Study? at two time points (baseline: 9 10 years and 2-year follow-up). Prenatal ozone exposure was calculated as a 9-month average of daily exposure estimates based on birth year and address. Social environmental factors included school environment and neighborhood safety at both time points. Structural MRI measures included bilateral amygdala and hippocampus volumes at both time points. Behavioral data consisted of cognition and PLEs scores at both time points. Moderation and moderated mediation models with cluster-robust standard errors were constructed to examine the effects, controlling for covariates. Results Children who were prenatally exposed to greater ozone and had a more unfavorable school environment exhibited a smaller increase in left hippocampal volume, leading to poorer cognition and more PLEs. Moreover, children who were prenatally exposed to greater ozone and lived in a more unsafe neighborhood had a larger increase in right amygdala volume. Conclusions This longitudinal study is the first to demonstrate the combined effects of prenatal ozone pollutant and adverse social environments in childhood on youth psychotic-like experiences and cognition, highlighting the limbic system as an important neural mechanism underlying the effects.

Developmental Changes in Brain Function Underlying Inhibitory Control in Autism Spectrum Disorders / Aarthi PADMANABHAN in Autism Research, 8-2 (April 2015)  

Public ISBD [article]  inAutism Research > 8-2 (April 2015) . - p.123-135 Titre : Developmental Changes in Brain Function Underlying Inhibitory Control in Autism Spectrum Disorders Type de document : texte imprimé Auteurs : Aarthi PADMANABHAN, Auteur ; Krista GARVER, Auteur ; Kirsten O'HEARN, Auteur ; Natalie NAWARAWONG, Auteur ; Ran LIU, Auteur ; Nancy MINSHEW, Auteur ; John SWEENEY, Auteur ; Beatriz LUNA, Auteur Article en page(s) : p.123-135 Langues : Anglais (eng) Mots-clés : autism  fMRI  inhibitory control  antisaccade  development  adolescence Index. décimale : PER Périodiques Résumé : The development of inhibitory control—the ability to suppress inappropriate actions in order to make goal-directed responses—is often impaired in autism spectrum disorders (ASD). In the present study, we examined whether the impairments in inhibitory control evident in ASD reflect—in part—differences in the development of the neural substrates of inhibitory control from adolescence into adulthood. We conducted a functional magnetic resonance imaging (fMRI) study on the anti-saccade task, a probe of inhibitory control, in high-functioning adolescents and adults with ASD compared to a matched group of typically developing (TD) individuals. The ASD group did not show the age-related improvements in behavioral performance from adolescence to adulthood evident in the typical group, consistent with previous behavioral work. The fMRI results indicated that much of the circuitry recruited by the ASD group was similar to the TD group. However, the ASD group demonstrated some unique patterns, including: (a) a failure to recruit the frontal eye field during response preparation in adolescence but comparable recruitment in adulthood; (b) greater recruitment of putamen in adolescence and precuneus in adolescence and adulthood than the TD group; and (c) decreased recruitment in the inferior parietal lobule relative to TD groups. Taken together, these results suggest that brain circuitry underlying inhibitory control develops differently from adolescence to adulthood in ASD. Specifically, there may be relative underdevelopment of brain processes underlying inhibitory control in ASD, which may lead to engagement of subcortical compensatory processes.

Fearful temperament in middle childhood predicts adolescent attention bias and anxiety symptoms: The moderating role of frontal EEG asymmetry / Ran LIU in Development and Psychopathology, 35-3 (August 2023)  

Public ISBD [article]  inDevelopment and Psychopathology > 35-3 (August 2023) . - p.1335-1345 Titre : Fearful temperament in middle childhood predicts adolescent attention bias and anxiety symptoms: The moderating role of frontal EEG asymmetry Type de document : texte imprimé Auteurs : Ran LIU, Auteur ; Martha Ann BELL, Auteur Article en page(s) : p.1335-1345 Langues : Anglais (eng) Mots-clés : anxiety  attention bias to threat  fearful temperament  frontal EEG asymmetry Index. décimale : PER Périodiques Résumé : The current study provided first analyses of the moderating effect of baseline-to-task frontal EEG asymmetry on the associations between 9-year fearful temperament and adolescent attention bias to threat as well as anxiety symptoms. Participants include a community sample of 122 children (60 boys, 62 girls; Mage = 14.66 years; Range = 11.82-18.13 years). Baseline-to-task frontal EEG asymmetry at age 9 moderated the relation between fearful temperament at age 9 and adolescent anxiety symptoms. Specifically, fearful temperament predicted adolescent anxiety symptoms when children showed greater right activation from baseline to an executive function task, but not greater left activation. Baseline-to-task frontal EEG asymmetry moderated the association between fearful temperament and sustained (i.e., stimulus onset asynchrony is 1250 ms) but not automatic attention bias (i.e., stimulus onset asynchrony is 500 ms). Children with greater left frontal activation from baseline to task more efficiently direct attention away from threat. Adolescent automatic attention bias to threat was related to concurrent anxiety symptoms. These findings illustrate the importance of considering frontal EEG asymmetry to shape how fearful children process threat and to influence their behavioral problems.

Frontal EEG asymmetry moderates the associations between negative temperament and behavioral problems during childhood / Ran LIU in Development and Psychopathology, 33-3 (August 2021)

CALKINS, Auteur ; Martha Ann BELL, Auteur Article en page(s) : p.1016-1025 Langues : Anglais (eng) Mots-clés : externalizing  fearful inhibition  frontal EEG asymmetry  impulsivity-anger  internalizing Index. décimale : PER Périodiques Résumé : Fearful inhibition and impulsivity-anger significantly predict internalizing and externalizing problems, respectively. An important moderator that may affect these associations is frontal EEG asymmetry (FA). We examined how temperament and FA at 6 years interactively predicted behavioral problems at 9 years. A community sample of 186 children (93 boys, 93 girls) participated in the study. Results indicated that the effect of fearful inhibition on parent-reported internalizing problems increased as children exhibited greater right FA. The effect of impulsivity-anger on parent-reported externalizing problems increased as children showed greater left FA. Because FA was allowed to vary rather than children being dichotomized into membership in left FA and right FA groups, we observed that children’s FA contributed to the resilience process only when FA reached specific asymmetry levels. These findings highlight the importance of considering the different functions of FA in combination with specific dimensions of temperament in predicting children’s socioemotional outcomes. Clinical implications include providing suggestions for intervention services by demonstrating the role of FA in developing behavioral problems and inspiring research on whether it is possible to alter EEG activation and thus potentially improve developmental outcomes.

MARGOLIS, Auteur Article en page(s) : p.1037-1044 Langues : Anglais (eng) Mots-clés : Air pollution  polycyclic aromatic hydrocarbons  prenatal  internalizing problems  shyness  anterior cingulate cortex Index. décimale : PER Périodiques Résumé : Background Prenatal exposure to air pollution increases the risk for psychiatric disorders characterized by internalizing problems. In this study, we examined the roles of shyness and anterior cingulate cortex (ACC) activity in the association between prenatal exposure to polycyclic aromatic hydrocarbons (PAH) and children's internalizing problems at 79years old. Methods Participants include 53 children (31 girls, 22 boys). Personal air monitoring was conducted over 48 continuous hours during the third trimester of pregnancy to measure 8 PAHs. Mothers reported children's shyness (Emotionality Activity Sociability Temperament Survey) at age 5 and internalizing problems (Child Behavior Checklist) at ages 79. ACC activity was measured by fMRI during the Simon Spatial Incompatibility task at ages 79. Results Shyness mediated the association between prenatal PAH exposure and internalizing problems. Higher prenatal PAH exposure predicted increased shyness, which in turn predicted greater internalizing problems. Moreover, left ACC activity during the Simon task moderated the association between prenatal PAH exposure and internalizing problems. Prenatal PAH exposure predicted increased risk for internalizing problems only when children showed heightened left ACC activity during the resolution of cognitive conflict. Conclusions Our study innovatively synthesizes the fields of developmental psychology and environmental health science to offer new insights into the risk factors for anxiety disorders. Facilitating the development of healthy reactive and regulatory processes may improve the developmental outcomes for children highly exposed to air pollution.
