ADHD is one of the most all-embracing neurodevelopmental disorders involving cognitive and behavioral aspects with repercussion in many environments of life of children and their families like social interaction and academic performance, and also with frequent association with psychiatric comorbidities. In this sense, we think that music, with its playful and spontaneous, affective, motivational, temporal and rhythmic dimension can be of great help to study many aspects of temporal processing related to ADHD. In this work we study time processing with sounds and music in children with ADHD, evaluating how time perception and expression in music is related to the modulation of executive and inhibitory control of impulsive behaviors related to ADHD with the hypothesis that children with ADHD have differentiated performance when compared with children with typical development in tasks of time estimation, production, reproduction of time durations and temporal synchronization with music. Objectives: Develop a battery of sound and musical tasks to evaluate and correlate performance of children with ADHD, with and without use of stimulant medication, compared to a control group of children with typical development. Method: 36 participants aged 6 to 14 years where recruted at NANI-Unifesp, sub-divided into three groups with 12 children: without medication, with medication, and control group. Evaluation sheets and data collected with the computer recorded the participant's performance in the tasks. Place: Serene’s Music Cognition Laboratory. Instrument: The tasks of BAMT were divided into the following sections: spontaneous time; time synchronization; time estimation with simple sounds; time estimation with music, and time reproduction. Results: 1 - The performance of group ADHD/SM in the task of temporal synchronization with music was statistically lower than the control group and ADHD/CM only when task reaches 60 seconds of accomplishment. 2 - Performance of ADHD/SM in temporal estimation of simple sounds in short time intervals (30 ms) was statistically lower than the control and ADHD/CM groups. 3 - Performance of ADHD/CM was higher than the ADHD/SM group and control group in time estimated with music. 4 – In the task of comparison between musical excerpts of the same duration, ADHD group (with and without medication) considered as longest the track that contained largest number of notes with longer durations (track 7). While in the control group, duration was related to the density of sound stimuli (musical notes). BAMT may be a proposal integrating areas such as music therapy, neuroscience and cognition within musical approach in order to minimize the impact and repercussions of pedagogical and educational disorders through positive mediation of art.
