For children, developing self-control is a critically important step toward success in academic settings and social relationships, yet there are few non-pharmacological approaches that have been successful in increasing self-control. We found in our earlier studies that self-control can be increased in preschool-aged children with high impulsivity by using games in which they practice gradually increasing wait-time for larger, more delayed rewards. We are performing this current study to test if this training to increase self-control can be increased using mobile app technology, with computerized game time being used as a reward.",[86],"Impulsivity",[88,89],"delay discounting","shaping","2026-06-02",{"date":92,"type":93},"2026-06-04","ACTUAL",{"date":95,"type":93},"2017-09-12",{"date":97,"type":80},"2026-08",{"name":5,"class":6},1]
