Brief Report: Atypical Expression of Distress During the Separation Phase of the Strange Situation Procedure in Infant Siblings at High Risk for ASD / Gianluca ESPOSITO in Journal of Autism and Developmental Disorders, 44-4 (April 2014)
[article]
Titre : Brief Report: Atypical Expression of Distress During the Separation Phase of the Strange Situation Procedure in Infant Siblings at High Risk for ASD Type de document : Texte imprimé et/ou numérique Auteurs : Gianluca ESPOSITO, Auteur ; Maria CARMEN ROSTAGNO, Auteur ; Paola VENUTI, Auteur ; John D. HALTIGAN, Auteur ; Daniel S. MESSINGER, Auteur Année de publication : 2014 Article en page(s) : p.975-980 Langues : Anglais (eng) Mots-clés : Cry Autism spectrum disorders Fundamental frequency Strange situation Behavior Index. décimale : PER Périodiques Résumé : Previous studies have provided preliminary evidence that disruptions in cry acoustics may be part of an atypical vocal signature of autism early in life. We examined the acoustic characteristics of cries extracted from the separation phase of the strange situation procedure in a sample of toddler of younger siblings of a child with autism spectrum disorder-autism spectrum disorders (ASD) (high risk, HR) and a low risk (LR) group. Cry samples derived from vocal recordings of 15-month-old HR (n = 13) and LR infants (n = 14) were subjected to acoustic analyses. HR toddlers, compared to those with LR, produced cries that were shorter and had a higher fundamental frequency (F0). Three HR toddlers later classified with an ASD at 36 months (autistic disorder in all cases) produced cries that had among the highest F0 and shortest durations. Taken together these results indicate that toddlers at high risk for ASD (and those with an ASD) express atypical patterns of distress in response a social stressor. Implications for early diagnosis and parenting are discussed.

Titre : Mother-infant cortisol attunement: Associations with mother-infant attachment disorganization Type de document : Texte imprimé et/ou numérique Auteurs : Jaclyn A. LUDMER NOFECH-MOZES, Auteur ; Brittany JAMIESON, Auteur ; Andrea GONZALEZ, Auteur ; Leslie ATKINSON, Auteur Article en page(s) : p.43-55 Langues : Anglais (eng) Mots-clés : attachment attunement cortisol disorganized strange situation Index. décimale : PER Périodiques Résumé : This study explores the conceptualization of mother-infant cortisol attunement both theoretically and empirically, and its association with mother-infant attachment disorganization. In a community sample (N = 256), disorganization and cortisol were assessed during the Strange Situation Procedure (SSP) at infant age 17 months. Salivary cortisol was collected at baseline, and 20 and 40 min after the SSP. We utilized three statistical approaches: correlated growth modeling (probing a simultaneous conceptualization of attunement), cross-lagged modeling (probing a lagged, reciprocal conceptualization of attunement), and a multilevel model difference score analysis (to examine the pattern of discrepancies in mother-infant cortisol values). Correlated growth modeling revealed that disorganized, relative to organized, dyads had significant magnitude of change over time, such that, among disorganized dyads, as mothers had greater declines in cortisol, infants had greater increases. The difference score analysis revealed that disorganized, relative to organized, dyads had a greater divergence between maternal and infant cortisol values, such that maternal values were lower than infant values. Disorganized attachment status was not significantly associated with attunement when conceptualized as reciprocal and lagged in the cross-lagged model. Findings suggest that mother-infant dyads in disorganized attachment relationships, who are by definition behaviorally misattuned, are also misattuned in their adrenocortical responses.
