Maternal depression, child frontal asymmetry, and child affective behavior as factors in child behavior problems / Erika E. FORBES in Journal of Child Psychology and Psychiatry, 47-1 (January 2006)
[article]
Titre : Maternal depression, child frontal asymmetry, and child affective behavior as factors in child behavior problems Type de document : Texte imprimé et/ou numérique Auteurs : Erika E. FORBES, Auteur ; Jennifer S. SILK, Auteur ; Daniel S. SHAW, Auteur ; Maria KOVACS, Auteur ; Nathan A. FOX, Auteur ; Jeffrey F. COHN, Auteur Année de publication : 2006 Article en page(s) : p.79–87 Langues : Anglais (eng) Mots-clés : Maternal-depression behavior-problems affect-regulation psychophysiology parent–child-interaction Index. décimale : PER Périodiques Résumé : Background: Despite findings that parent depression increases children's risk for internalizing and externalizing problems, little is known about other factors that combine with parent depression to contribute to behavior problems.
Methods: As part of a longitudinal, interdisciplinary study on childhood-onset depression (COD), we examined the association of mother history of COD, child frontal electroencephalogram asymmetry, and affective behavior with children's concurrent behavior problems.
Results: Children in the COD group had higher anxious/depressed and aggressive problems than did children in the control group, but this was qualified by a COD-by-asymmetry interaction effect. For COD but not control children, left frontal asymmetry was associated with both anxious/depressed and aggressive child problems. Children with left frontal asymmetry and low affect regulation behavior had higher anxious/depressed problems than did those with high affect regulation behavior. Boys with left frontal asymmetry had higher aggressive problems than did those with right frontal asymmetry.
Conclusions: In children of mothers with COD, physiological and behavioral indices of affect regulation may constitute risks for behavior problems.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2005.01442.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=706

Titre : Objective measurement of head movement differences in children with and without autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : K. B. MARTIN, Auteur ; Z. HAMMAL, Auteur ; G. REN, Auteur ; Jeffrey F. COHN, Auteur ; J. CASSELL, Auteur ; M. OGIHARA, Auteur ; Jennifer C. BRITTON, Auteur ; A. GUTIERREZ, Auteur ; D. S. MESSINGER, Auteur Article en page(s) : 14p. Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Head movement Motor movement Social processing Index. décimale : PER Périodiques Résumé : Background: Deficits in motor movement in children with autism spectrum disorder (ASD) have typically been characterized qualitatively by human observers. Although clinicians have noted the importance of atypical head positioning (e.g. social peering and repetitive head banging) when diagnosing children with ASD, a quantitative understanding of head movement in ASD is lacking. Here, we conduct a quantitative comparison of head movement dynamics in children with and without ASD using automated, person-independent computer-vision based head tracking (Zface). Because children with ASD often exhibit preferential attention to nonsocial versus social stimuli, we investigated whether children with and without ASD differed in their head movement dynamics depending on stimulus sociality. Methods: The current study examined differences in head movement dynamics in children with (n = 21) and without ASD (n = 21). Children were video-recorded while watching a 16-min video of social and nonsocial stimuli. Three dimensions of rigid head movement-pitch (head nods), yaw (head turns), and roll (lateral head inclinations)-were tracked using Zface. The root mean square of pitch, yaw, and roll was calculated to index the magnitude of head angular displacement (quantity of head movement) and angular velocity (speed). Results: Compared with children without ASD, children with ASD exhibited greater yaw displacement, indicating greater head turning, and greater velocity of yaw and roll, indicating faster head turning and inclination. Follow-up analyses indicated that differences in head movement dynamics were specific to the social rather than the nonsocial stimulus condition. Conclusions: Head movement dynamics (displacement and velocity) were greater in children with ASD than in children without ASD, providing a quantitative foundation for previous clinical reports. Head movement differences were evident in lateral (yaw and roll) but not vertical (pitch) movement and were specific to a social rather than nonsocial condition. When presented with social stimuli, children with ASD had higher levels of head movement and moved their heads more quickly than children without ASD. Children with ASD may use head movement to modulate their perception of social scenes.
