两只猴子被训练举起杠杆，手腕伸展以响应视觉提示。动物被长期植入电极记录经皮层场电位。在过渡学习阶段，当动物不确定是否适当地完成所需任务时，在前扣带皮层区域24中观察到独特的“错误"电位。在这个阶段（III），大约40-60%的动作是在所需的提示时间内进行的。 错误的潜力不适当的杠杆升降机与手腕的运动，是自我节奏，因此非奖励，但这样的潜力并没有遵循适当的，即视觉启动，奖励升降机。
Two monkeys were trained to lift a lever with wrist extension in response to a visual cue. The animals were chronically implanted with electrodes for recording transcortical field potentials. Unique ''error'' potentials were observed in the anterior cingulate cortical area 24 during a transitional learning-stage when the animals were uncertain about fulfilling the required task appropriately. At that stage (III) about 40-60% of the movements were made appropriately within the required cue-time. Error potentials followed inappropriate lever lifts made with wrist movements that were self-paced and hence non-rewarded, but such potentials did not follow appropriately made, i.e. visually initiated, and rewarded lifts.
