Critical periods for the neurodevelopmental processes of externalizing and internalizing / Don M. TUCKER in Development and Psychopathology, 27-2 (May 2015)  

Public ISBD [article]  inDevelopment and Psychopathology > 27-2 (May 2015) . - p.321-346 Titre : Critical periods for the neurodevelopmental processes of externalizing and internalizing Type de document : Texte imprimé et/ou numérique Auteurs : Don M. TUCKER, Auteur ; Catherine POULSEN, Auteur ; Phan LUU, Auteur Article en page(s) : p.321-346 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Research on neurobiological development is providing insight into the nature and mechanisms of human neural plasticity. These mechanisms appear to support two different forms of developmental learning. One form of learning could be described as externalizing, in which neural representations are highly responsive to environmental influences, as the child typically operates under a mode of hedonic approach. A second form of learning supports internalizing, in which motive control separates attention and self-regulation from the immediate influences of the context, particularly when the child faces conditions of avoidance and threat. The dorsal cortical networks of externalizing are organized around dorsal limbic (cingulate, septal, lateral hypothalamic, hippocampal, and ventral striatal) circuits. In contrast, the ventral cortical networks of internalizing are organized around ventral limbic (anterior temporal and orbital cortex, extended amygdala, dorsal striatal, and mediodorsal thalamic) circuits. These dual divisions of the limbic system in turn self-regulate their arousal levels through different brain stem and forebrain neuromodulator projection systems, with dorsal corticolimbic networks regulated strongly by locus coeruleus norepinephrine and brain stem raphe nucleus serotonin projection systems, and ventral corticolimbic networks regulated by ventral tegmental dopamine and forebrain acetylcholine projections. Because the arousal control systems appear to regulate specific properties of neural plasticity in development, an analysis of these systems explains differences between externalizing and internalizing at multiple levels of neural and psychological self-regulation. In neuroscience, the concept of critical periods has been applied to times when experience is essential for the maturation of sensory systems. In a more general neuropsychological analysis, certain periods of the child's development require successful self-regulation through the differential capacities for externalizing and internalizing.

Frontolimbic activity in a frustrating task: Covariation between patterns of coping and individual differences in externalizing and internalizing symptoms / Ida MOADAB in Development and Psychopathology, 22-2 (May 2010)  

Public ISBD [article]  inDevelopment and Psychopathology > 22-2 (May 2010) . - p.391-404 Titre : Frontolimbic activity in a frustrating task: Covariation between patterns of coping and individual differences in externalizing and internalizing symptoms Type de document : Texte imprimé et/ou numérique Auteurs : Ida MOADAB, Auteur ; Thomas J. DISHION, Auteur ; Tara GILBERT, Auteur ; Don M. TUCKER, Auteur Année de publication : 2010 Article en page(s) : p.391-404 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Many problem behaviors in youth have been attributed to maladaptive self-regulation in response to frustration. Frontolimbic networks that promote flexible as well as over- and undercontrolled regulation could provide evidence linking cortical mechanisms of self-regulation to the development of internalizing or externalizing symptomology. Specifically, ineffective dorsally mediated inhibitory control may be associated with rule-breaking and substance use behaviors, whereas overengagement of ventral limbic systems responsible for self-monitoring of errors may increase risk of developing anxious and depressed symptomology. In this study, a sample of 9- to 13-year-old children were presented with an emotional go/no-go task. Event-related potentials were used to identify differences in cortical mechanisms related to inhibitory control (indexed with the stimulus-locked medial frontal negativity) and self-monitoring (indexed with the error-related negativity). These measurements were then related to externalizing and internalizing behaviors. As predicted, externalizing problems were associated with smaller medial frontal negativity amplitudes, which indicate undercontrolled self-regulation and poor dorsal mediation of actions. Internalizing symptoms were related to larger error-related negativity amplitudes, demonstrating overregulation and overengagement of ventral limbic systems. These findings suggest that the use of event-related potential methodology with paradigms that elicit cognition–emotion can provide insight into the neural mechanisms of regulatory deficits that result in problem behaviors in youth.
