Executive and Motivational Control of Performance Task Behavior, and Autonomic Heart-rate Regulation in Children: Physiologic Validation of Two-factor Solution Inhibitory Control / Enrico MEZZACAPPA in Journal of Child Psychology and Psychiatry, 39-4 (May 1998)
[article]
Titre : Executive and Motivational Control of Performance Task Behavior, and Autonomic Heart-rate Regulation in Children: Physiologic Validation of Two-factor Solution Inhibitory Control Type de document : Texte imprimé et/ou numérique Auteurs : Enrico MEZZACAPPA, Auteur ; Daniel KINDLON, Auteur ; Philip SAUL, Auteur ; Felton EARLS, Auteur Année de publication : 1998 Article en page(s) : p.525-531 Langues : Anglais (eng) Mots-clés : Psychophysiology impulsivity motivation heart-rate variability executive control Index. décimale : PER Périodiques Résumé : Forty-two (42) children (mean age 10.6 years) from mainstream public (N= 22) and therapeutic schools (N= 20) completed performance tasks assessing executive and motivational influences on motor responses. In a separate protocol, children underwent physiologic challenges of paced breathing and supine to standing postural change, while heart rate was continuously monitored.
Executive control was associated with vagal modulation of respiratory driven, high-frequency heart-rate variability (t= 2.20, p < .03), whereas motivational control was associated with sympathetic modulation of posturally driven, low-frequency heart-rate variability (t= -2.22, p < .03). These findings supported a two-factor solution of inhibitory control derived in a previous study.Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=123

Titre : Physiological markers of anxiety are increased in children of abused mothers Type de document : Texte imprimé et/ou numérique Auteurs : Tanja JOVANOVIC, Auteur ; Ami SMITH, Auteur ; Asante KAMKWALALA, Auteur ; James POOLE, Auteur ; Tara SAMPLES, Auteur ; Seth D. NORRHOLM, Auteur ; Kerry J. RESSLER, Auteur ; Bekh BRADLEY, Auteur Année de publication : 2011 Article en page(s) : p.844-852 Langues : Anglais (eng) Mots-clés : Child abuse maternal trauma child anxiety startle response heart-rate variability Index. décimale : PER Périodiques Résumé : Background: A growing number of studies indicate that low income, African American men and women living in urban environments are at high risk for trauma exposure, which may have intergenerational effects. The current study employed psychophysiological methods to describe biomarkers of anxiety in children of traumatized mothers.
Methods: Study participants were recruited from a highly traumatized urban population, comprising mother–child pairs (n = 36) that included school-age children. Mothers were assessed for childhood abuse with the Childhood Trauma Questionnaire, as well as symptoms of depression and posttraumatic stress disorder (PTSD). The children were measured for dark-enhanced startle responses and heart-rate variability.
Results: Dark-enhanced startle was found to be higher in children whose mothers had high levels of childhood physical abuse, as compared to children whose mothers had low levels of physical abuse. During the habituation phase of the startle experiment, children whose mothers had high levels of childhood emotional abuse had higher sympathetic system activation compared to children of mothers with low emotional abuse. These effects remained significant after accounting for maternal symptoms of PTSD and depression, as well as for the child’s trauma exposure.
Conclusion: These results demonstrate that children of mothers who have history of childhood physical and emotional abuse have higher dark-enhanced startle as well as greater sympathetic nervous system activation than children of mothers who do not report a history of childhood physical and emotional abuse, and emphasize the utility of physiological measures as pervasive biomarkers of psychopathology that can easily be measured in children.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2011.02410.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=132
