MATTINGLEY, Auteur ; Therese ENGLISH, Auteur ; Robert HESTER, Auteur ; Alasdair VANCE, Auteur Année de publication : 2009 Article en page(s) : p.1064-1072 Langues : Anglais (eng) Mots-clés : Selective-attention flanker-interference spatial-bias ADHD spatial-attention Index. décimale : PER Périodiques Résumé : Background: Evidence for a selective attention abnormality in children with attention deficit hyperactivity disorder (ADHD) has been hard to identify using conventional methods from cognitive science. This study tested whether the presence of selective attention abnormalities in ADHD may vary as a function of perceptual load and target lateralisation. Given evidence of right-hemisphere dysfunction in ADHD we predicted increased interference effects for right, but not left-sided target displays, particularly under low perceptual load. Method: Fourteen children with ADHD-C and 14 typically developing children were tested on a modified flanker task under low and high perceptual load. We also sought evidence for our hypothesis in a re-analysis of an independent data set (42 ADHD; 34 typically developing) in which load effects on selective attention in ADHD were previously examined (Huang-Pollock, Nigg, & Carr, 2005). Results: As predicted, all children showed evidence of greater interference by flankers under low compared with high perceptual load conditions. Crucially, however, children with ADHD showed the greatest interference effect for right-sided target displays under low but not high perceptual load. In contrast, typically developing children showed the greatest interference for left-sided target displays. The magnitude of interference for right-sided targets was also positively correlated with ADHD symptom levels. Re-analysis of an independent data set (Huang-Pollock et al., 2005) further confirmed our findings. Conclusions: This study demonstrates that interference effects in children with ADHD and typically developing children are spatially asymmetrical but opposite in direction. The pattern of right-sided interference effects in children with ADHD suggests disruption within right hemisphere attentional networks in ADHD.

Can reciprocated parent-child eye gaze and emotional engagement enhance treatment for children with conduct problems and callous-unemotional traits: a proof-of-concept trial / Mark R. DADDS in Journal of Child Psychology and Psychiatry, 60-6 (June 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-6 (June 2019) . - p.676-685 Titre : Can reciprocated parent-child eye gaze and emotional engagement enhance treatment for children with conduct problems and callous-unemotional traits: a proof-of-concept trial Type de document : texte imprimé Auteurs : Mark R. DADDS, Auteur ; Therese ENGLISH, Auteur ; Subodha WIMALAWEERA, Auteur ; Olivia SCHOLLAR-ROOT, Auteur ; David J. HAWES, Auteur Article en page(s) : p.676-685 Langues : Anglais (eng) Mots-clés : Conduct disorder  callous-unemotional traits  eye gaze  parent training  parent-child interaction Index. décimale : PER Périodiques Résumé : BACKGROUND: High levels of callous-unemotional (CU) traits are associated with reduced effectiveness of parenting programmes for children with conduct problems. This may be due to low levels of emotional engagement (EE) by these children with their parents. We evaluate a theoretically driven strategy for improving emotional engagement in high CU traits children undergoing a parenting intervention (parent management training; PMT) for child conduct problems. METHODS: N = 40, 3- to 8-year-old children referred for conduct problems and showing stable, high levels of CU traits, were randomised to receive PMT+Emotional Engagement (EE), or the control condition PMT+Child Centred Play (CCP). A benchmarking sample of N = 70 children who received PMT only was also included. Observational coding of the parent-child interactions targeted by EE and CCP respectively was repeated throughout treatment and follow-up. RESULTS: Emotional engagement produced unique improvements in parent-child emotional engagement (shared eye gaze); however, these reverted to baseline levels after treatment. CCP produced unique improvements in parents' child centeredness and child positive play, but by post-treatment, all children had improved on these factors. Both interventions produced similar improvements in general parental warmth. Reductions in severity of conduct problems at post-treatment and follow-up were large in size and did not differ between conditions or from the benchmarking group. Levels of CU traits reduced significantly but again did not differ between groups. CONCLUSIONS: The putative mechanism of emotional engagement through reciprocated eye gaze proved to be impervious to sustained change, and thus failed to have a specific impact of conduct problems or levels of CU traits. The development of novel treatment approaches to children with high levels of CU is a challenging endeavour, and these results indicate that focussing on children with stable levels at pretreatment should be a priority.
