Recalibration of the stress response system over adult development: Is there a perinatal recalibration period? / Mariann A. HOWLAND in Development and Psychopathology, 35-5 (December 2023)
[article]
Titre : Recalibration of the stress response system over adult development: Is there a perinatal recalibration period? Type de document : Texte imprimé et/ou numérique Auteurs : Mariann A. HOWLAND, Auteur Article en page(s) : p.2315-2337 Mots-clés : perinatal postpartum pregnancy recalibration stress Index. décimale : PER Périodiques Résumé : During early life-sensitive periods (i.e., fetal, infancy), the developing stress response system adaptively calibrates to match environmental conditions, whether harsh or supportive. Recent evidence suggests that puberty is another window when the stress system is open to recalibration if environmental conditions have shifted significantly. Whether additional periods of recalibration exist in adulthood remains to be established. The present paper draws parallels between childhood (re)calibration periods and the perinatal period to hypothesize that this phase may be an additional window of stress recalibration in adult life. Specifically, the perinatal period (defined here to include pregnancy, lactation, and early parenthood) is also a developmental switch point characterized by heightened neural plasticity and marked changes in stress system function. After discussing these similarities, lines of empirical evidence needed to substantiate the perinatal stress recalibration hypothesis are proposed, and existing research support is reviewed. Complexities and challenges related to delineating the boundaries of perinatal stress recalibration and empirically testing this hypothesis are discussed, as well as possibilities for future multidisciplinary research. In the theme of this special issue, perinatal stress recalibration may be a mechanism of multilevel, multisystem risk, and resilience, both intra-individually and intergenerationally, with implications for optimizing interventions.

Titre : Atypical rapid audio-visual temporal recalibration in autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Jean-Paul NOEL, Auteur ; Matthew A. DE NIEAR, Auteur ; Ryan STEVENSON, Auteur ; David ALAIS, Auteur ; Mark T. WALLACE, Auteur Article en page(s) : p.121-129 Langues : Anglais (eng) Mots-clés : autism multisensory audio-visual plasticity recalibration Index. décimale : PER Périodiques Résumé : Changes in sensory and multisensory function are increasingly recognized as a common phenotypic characteristic of Autism Spectrum Disorders (ASD). Furthermore, much recent evidence suggests that sensory disturbances likely play an important role in contributing to social communication weaknesses—one of the core diagnostic features of ASD. An established sensory disturbance observed in ASD is reduced audiovisual temporal acuity. In the current study, we substantially extend these explorations of multisensory temporal function within the framework that an inability to rapidly recalibrate to changes in audiovisual temporal relations may play an important and under-recognized role in ASD. In the paradigm, we present ASD and typically developing (TD) children and adolescents with asynchronous audiovisual stimuli of varying levels of complexity and ask them to perform a simultaneity judgment (SJ). In the critical analysis, we test audiovisual temporal processing on trial t as a condition of trial t???1. The results demonstrate that individuals with ASD fail to rapidly recalibrate to audiovisual asynchronies in an equivalent manner to their TD counterparts for simple and non-linguistic stimuli (i.e., flashes and beeps, hand-held tools), but exhibit comparable rapid recalibration for speech stimuli. These results are discussed in terms of prior work showing a speech-specific deficit in audiovisual temporal function in ASD, and in light of current theories of autism focusing on sensory noise and stability of perceptual representations.
