简要总结
The aim of this study is to analyse explicit and implicit emotional information processing abilities in children with attention deficit disorder with or without hyperactivity
详细描述
The main symptoms of Attentional Deficit Hyperactivity Disorder (ADHD) are inattention, motor agitation and impulsivity. However, other dysfunctions affecting the quality of life remain poorly studied: lack of understanding and management of emotions, focus on the local aspects of a visual scene limiting the ability to assign a general meaning to the scene and alteration of long-term memory encoding. This study aims to analyse these difficulties using different tasks requiring processing of rich and varied everyday images, having high ecological validity. It involves the participation of 56 boys and girls with ADHD, aged 7 to 12 years. A first phase examines the immediate understanding of images using two tasks: semantic categorization (Experiment 1) and emotional evaluation (Experiment 2) of images with positive, negative or neutral emotional valence, and depicting real environments (natural vs. manufactured contexts) or foreground objects pasted into a noise background (inanimate objects vs. animals vs. people. In each trial, one context image and one object image are presented briefly and simultaneously, one in each visual field. In order to be appropriately understood in both their semantic and emotional contents, context images will require more global processing, while object images will require more local, detailed processing. Their semantic (Exp. 1) and emotional (Exp. 2) consistency is manipulated. A week later, the participants have to perform a memory task requiring old/new recognition in a two-alternative forced choice (2AFC) paradigm that presents in each trial a pair of images (one old, one new) having the same emotional valence (Exp. 3). The study will characterize the specificities of processing and representing visual emotional information in ADHD children. The results will be compared with those from a previous study we conducted with the same methodology on neuro-typical children (controls).

结局指标
主要结局
1. Accuracy and response time at an explicit emotional evaluation task of visual scenes, by children with Attentional Deficit Hyperactivity Disorder (ADHD)
时间窗: at baseline Day 0
The performance at the emotional evaluation task is analyzed by association of two separate outcomes measures: measure of efficiency by the accuracy (i.e. proportion of correct response) and measure of the effectiveness by the response time at the correct trials (in milliseconds). This experiment analyzed the explicit processing of visual scenes' emotional content .
2. Accuracy and response time at a semantic categorization task of visual scenes, by children with Attentional Deficit Hyperactivity Disorder (ADHD)
时间窗: at baseline Day 0
The performance at the semantic categorization task is analyzed by association of two separate outcomes measures: measure of efficiency by the accuracy (i.e. proportion of correct response) and measure of the effectiveness by the response time at the correct trials (in milliseconds). This experiment analyzed the implicit processing of visual scenes' emotional content .
次要结局
- Proportion and response time of correct response for the contextual images compared to the local images at the semantic categorization task for ADHD's participants(at baseline Day 0)
- Proportion and response time of correct response for the contextual images compared to the local images at the emotional evaluation task for ADHD's participants(at baseline Day 0)
- Influence of the image's emotional content (i.e. neutral, positive or negative) on long term memory in ADHD participants(at 1 week from the first evaluation)
- Performance on long term memory in ADHD participants(at 1 week from the first evaluation)
