Allostasis and the developing human brain: Explicit consideration of implicit models / Barbara L. GANZEL in Development and Psychopathology, 23-4 (November 2011)  

Public ISBD [article]  inDevelopment and Psychopathology > 23-4 (November 2011) . - p.955-974 Titre : Allostasis and the developing human brain: Explicit consideration of implicit models Type de document : Texte imprimé et/ou numérique Auteurs : Barbara L. GANZEL, Auteur ; Pamela A. MORRIS, Auteur Année de publication : 2011 Article en page(s) : p.955-974 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We previously used the theory of allostasis as the foundation for a model of the current stress process. This work highlighted the core emotional systems of the brain as the central mediator of the relationship between stress and health. In this paper, we extend this theoretical approach to consider the role of developmental timing. In doing so, we note that there are strong implicit models that underlie current developmental stress research in the social and life sciences. We endeavor to illustrate these models explicitly as we review the evidence behind each one and discuss their implications. We then extend these models to reflect recent findings from research in life span human neuroscience. The result is a new set of developmental allostatic models that provide fodder for future empirical research, as well as novel perspectives on intervention.

More than maths and mindreading: Sex differences in empathizing/systemizing covariance / Jeffrey M. VALLA in Autism Research, 3-4 (August 2010)

CHEN, Auteur ; Keith J. YODER, Auteur ; Barbara L. GANZEL, Auteur ; Stephanie K.L. WONG, Auteur Année de publication : 2010 Article en page(s) : p.174-184 Langues : Anglais (eng) Mots-clés : empathizing systemizing extreme-male brain mindreading cognitive-style normal-cognitive-variation Index. décimale : PER Périodiques Résumé : Empathizing–Systemizing theory posits a continuum of cognitive traits extending from autism into normal cognitive variation. Covariance data on empathizing and systemizing traits have alternately suggested inversely dependent, independent, and sex-dependent (one sex dependent, the other independent) structures. A total of 144 normal undergraduates (65 men, 79 women) completed the Reading the Mind in the Eyes, Embedded Figures, and Benton face recognition tests, the Autism Spectrum Quotient, and measures of digit length ratio and field of study; some also completed tests of motion coherence threshold (64) and go/no-go motor inhibition (128). Empathizing and systemizing traits were independent in women, but largely dependent in men. In men, level of systemizing skill required by field of study was directly related to social interactive and mindreading deficits; men's social impairments correlated with prolonged go/no-go response times, and men tended to apply systemizing strategies to solve problems of empathizing or global processing: rapid perceptual disembedding predicted heightened sensitivity to facial emotion. In women, level of systemizing in field was related to male-typical digit ratios and autistic superiorities in detail orientation, but not to autistic social and communicative impairments; and perceptual disembedding was related to social interactive skills but independent of facial emotion and visual motion perception.

Stress and the healthy adolescent brain: Evidence for the neural embedding of life events / Barbara L. GANZEL in Development and Psychopathology, 25-4 (November 2013)  

Public ISBD [article]  inDevelopment and Psychopathology > 25-4 (November 2013) . - p.879-889 Titre : Stress and the healthy adolescent brain: Evidence for the neural embedding of life events Type de document : Texte imprimé et/ou numérique Auteurs : Barbara L. GANZEL, Auteur ; Pilyoung KIM, Auteur ; Heather GILMORE, Auteur ; Nim TOTTENHAM, Auteur ; Elise TEMPLE, Auteur Article en page(s) : p.879-889 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Little is known about the long-term neural consequences of adverse life events for healthy adolescents, and this is particularly the case for events that occur after a putative stress-sensitive period in early childhood. In this functional magnetic resonance imaging study of healthy adolescents, we found that prior exposure to severe adverse life events was associated with current anxiety and with increased amygdala reactivity to standardized emotional stimuli (viewing of fearful faces relative to calm ones). Conjunction analyses identified multiple regions, including the amygdala, insula, and prefrontal cortex, in which reactivity to emotional faces covaried with life events as well as with current anxiety. Our morphometric analyses suggest systemic alterations in structural brain development with an association between anxiety symptoms and global gray matter volume. No life events were reported for the period before 4 years of age, suggesting that these results were not driven by exposure to stress during an early sensitive period in development. Overall, these data suggest systemic effects of traumatic events on the dynamically developing brain that are present even in a nonclinical sample of adolescents.
