Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: semantic group
Half of the participants (named the "semantic group") perform a semantic categorisation task.
Other: Semantic group
The "semantic task" has to categorise semantically (i.e., type of contexts or type of objects) one image at each trial.
Experimental: emotional group
Half of the participants (named the "emotional group") perform an emotional evaluation task.
Other: Emotional group
The "emotional task" has to evaluate the emotional content (i.e., neutral, positive or negative) of one image at each trial.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
1. Accuracy and response time at an explicit emotional evaluation task of visual scenes, by children with Attentional Deficit Hyperactivity Disorder (ADHD)
Time Frame: 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 .
at baseline Day 0
2. Accuracy and response time at a semantic categorization task of visual scenes, by children with Attentional Deficit Hyperactivity Disorder (ADHD)
Time Frame: 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 .
at baseline Day 0

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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
Time Frame: at baseline Day 0
The performance 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).
at baseline Day 0

Time Frame: at 1 week from the first evaluation
