A significant percentage of school-aged children present attention deficits or are diagnosed with Attention Deficit Hyperactivity Disorder (ADHD), a chronic neurodevelopmental disorder. Children with attention deficits or an ADHD diagnosis often present difficulties:

• in focusing their attention of specific important information (e.g., the teacher delivering a lesson) while ignoring other unimportant elements of the environment (e.g., noise outside the classroom),

• in maintaining and concentrating attention on an activity for a significant period of time (e.g., listening to a story)

• in working memory (attention is important for the information to pass in our memory) and,

• in impulse control (e.g., they cannot wait for their turn)

Attention is important for effective memory and learning, listening and observation, as well as for the appropriate response and reaction to elements of the environment. Thus, problems resulting from attention deficits are expressed in low academic performance, undesirable behaviors, and probles in family and peer relationships.
