Evaluating differences in Pavlovian fear acquisition and extinction as predictors of outcome from cognitive behavioural therapy for anxious children / Allison M. WATERS in Journal of Child Psychology and Psychiatry, 57-7 (July 2016)
[article]
Titre : Evaluating differences in Pavlovian fear acquisition and extinction as predictors of outcome from cognitive behavioural therapy for anxious children Type de document : Texte imprimé et/ou numérique Auteurs : Allison M. WATERS, Auteur ; Daniel S. PINE, Auteur Article en page(s) : p.869-876 Langues : Anglais (eng) Mots-clés : Anxiety children conditioning extinction treatment Index. décimale : PER Périodiques Résumé : Background Extinction is a key theoretical model of exposure-based treatments, such as cognitive behavioural therapy (CBT). This study examined whether individual differences in physiological responses and subjective stimulus evaluations as indices of fear extinction predicted response to CBT. Methods Thirty-two nonanxious comparisons and 44 anxious, 7-to-13-year-old children completed a Pavlovian conditioning and extinction task. Anxious children then completed group-based CBT. Skin conductance responses (SCRs) as well as subjective arousal and valence evaluations were measured in response to a conditioned stimulus paired with an aversive tone (CS+) and another conditioned stimulus presented alone (CS?). Both stimuli were presented alone during extinction. Diagnostic and symptom measures were completed before and after treatment. Results Like nonanxious comparisons, treatment responders did not acquire conditioned negative stimulus evaluations and displayed elevated SCRs that declined significantly across extinction trials. Nonresponders, by contrast, showed elevated negative stimulus evaluations of both CSs that were sensitive to extinction trials but showed no change in SCRs during extinction. Change in physiological but not evaluative indices of fear extinction predicted better treatment outcomes. Conclusions Individual differences in evaluative and physiological indices of fear extinction might moderate response to CBT.

Titre : Stimulus Over-Selectivity and Extinction-Induced Recovery of Performance as a Product of Intellectual Impairment and Autism Severity Type de document : Texte imprimé et/ou numérique Auteurs : Michelle P. KELLY, Auteur ; Geraldine LEADER, Auteur ; Phil REED, Auteur Article en page(s) : p.3098-3106 Langues : Anglais (eng) Mots-clés : Over-selectivity Extinction Comparator deficit Intellectual impairment Autism severity Index. décimale : PER Périodiques Résumé : The current experiment investigated the extent to which three variables (autism severity, nonverbal intellectual functioning, and verbal intellectual functioning) are associated with over-selective responding in a group of children with Autism Spectrum Disorder. This paper also analyzed the association of these three variables with the recovery of responding to a previously under-selected stimulus following extinction of the previously over-selected stimulus. The results demonstrated that participants showed over-selectivity, and demonstrated that extinction of the over-selected stimulus led to recovery of responding to the previously under-selected stimulus. For both over-selectivity, and recovery from over-selectivity, verbal functioning appeared to predict the effects most strongly, with greater over-selectivity in the lower functioning individuals, and greater recovery in the higher functioning individuals.
