Three adolescents with traumatic brain injury performed a physical therapy task in the absence of programmed consequences or duration requirements. Next, the experimenter gave the participants the options of a smaller immediate reinforcer with no response requirement or a larger delayed reinforcer with a response requirement. Self-control training exposed participants to a procedure during which they chose between a smaller immediate reinforcer and a progressively increasing delayed reinforcer whose values varied and were determined by a die roll. The participants chose whether they or the experimenter rolled the die. All participants initially demonstrated low baseline durations of the physical therapy task, chose the smaller immediate reinforcer during the choice baseline, and changed their preference to the larger delayed reinforcer during self-control training.
三名患有创伤性脑损伤的青少年在没有编程后果或持续时间要求的情况下进行物理治疗任务。接下来，实验者给参与者提供了两种选择：较小的即时奖励，无反应要求，或较大的延迟奖励，有反应要求。自我控制训练使参与者经历了一个过程，在这个过程中，他们在一个较小的即时奖励和一个逐渐增加的延迟奖励之间进行选择，延迟奖励的价值是变化的，由掷骰子决定。参与者选择是自己还是实验者掷骰子。所有参与者最初都表现出较低的物理治疗任务基线持续时间，在选择基线期间选择了较小的即时奖励，并且在自我控制训练期间将他们的偏好改变为较大的延迟奖励。
