The effect of background sounds on mind wandering.

Mind wandering (MW) reflects a situation in which the cognitive system is detached from the main task and involved with inner thoughts. It has been well document that music and other background sounds can have positive effects on number of cognitive functioning. In addition, other body of literature suggests that background sounds might have specifically positive effect on individuals with more attention deficiencies. Hence, the current study examines the effect of background sounds on MW. In two experiments, the effect of background sounds: music (Experiment 1) or an alerting tone (Experiment 2) while performing sustained attention tasks was examined among typical development participants with different severity of attention deficiency. Background sounds were found to reduce MW especially in individuals with more ADHD symptoms. This was further discussed in the context of several theories, and it was suggested that background sound might be used as a tool for MW reduction.
