自我控制被定义为放弃即时满足以获得更大的回报。工具的使用可能与自我控制有关，因为这两种行为都可能需要对自己的行为有远见和有意识的控制。作者评估了 20 只卷尾猴 (Cebus apella) 在工具任务中延迟满足的能力。受试者被给予棒状食物，这些食物可以立即食用，也可以被带到设备上并用于提取更喜欢的食物。作者发现一些猴子能够表现出自我控制能力。具有相对较多工具使用经验的猴子表现出最高水平的自我控制能力。这些结果表明，当存在更高质量的强化物时，卷尾猴能够延迟满足，并且工具经验可以影响这项任务的自我控制水平。
Self-control is defined as forgoing immediate gratification to obtain a greater reward. Tool use may relate to self-control because both behaviors may require foresight and deliberate control over one's actions. The authors assessed 20 capuchin monkeys (Cebus apella) for the ability to delay gratification in a tool task. Subjects were given rod-shaped food items that could either be consumed immediately or be carried to an apparatus and used to extract a more preferred food. The authors found that some monkeys were able to exhibit self-control. Monkeys with relatively more tool use experience demonstrated the greatest levels of self-control. These results indicate that capuchins are capable of delaying gratification when a higher quality reinforcer is present and that tool experience can influence levels of self-control in this task.
