由于重复操作性表现促进了从目标导向的行动到习惯性反应的转变，因此行动-结果的权变学习先于这一转变，并且对于这一转变是必要的。同时，它是已知的，在固定的时间间隔（FI）的时间表，其中的强化是可预测的操作性能，是耐习惯。然而，FI计划阻止习惯表达的原因仍然不清楚。我们推断，持续关注某个时间段可能需要一个目标导向的过程，并阻止过渡。为了验证这一假设，大鼠进行FI时间表操作训练，而听觉线索提供的方式无论是偶然或非偶然的杠杆按压的时间，以获得奖励。受试者在偶然线索的情况下养成了一种习惯，而在非偶然线索或没有线索的情况下则没有。总的来说，我们的结论是，从持续的注意力负担中释放出来可以表达习惯。(147（文字）
As repeated operant performance promotes the transition from goal-directed action to habitual response, it appears that action-outcome contingency learning precedes and is necessary for the transition. Meanwhile, it is known that operant performance under a fixed interval (FI) schedule, in which the timing of reinforcement is predictable, is resistant to habit. However, the reason why the FI schedule prevents habit expression remains unclear. We reasoned that sustained attention for monitoring a certain interval might require a goal-directed process and prevent the transition. To verify this hypothesis, rats underwent FI schedule operant training while auditory cues were provided in a manner either contingent or non-contingent with the timing of lever pressing to obtain a reward. The subjects developed a habit with contingent cues, but not with either non-contingent cues or no cues. Overall, we conclude that the release from sustained attentional burden allows the expression of habit. (147 words)
