蝾螈进行了大量的试验条件下训练，然后熄灭在一个直的小巷，以评估部分强化灭绝效应（PREE）。有四组：一个部分强化组使用随机时间表（RA）训练，两个部分强化组的强化比率逐渐增加（GI）或减少（GD），以及一个连续强化组（CR）。它们表现出明显的获得和灭绝效应。CR组对灭绝的抵抗力最强，其他三组之间无显著差异。结果表明，蝾螈的反向PREE，并建议他们的学习主要是由一个简单的加强-减弱机制。
Newts were trained under a massed-trial condition and then extinguished in a straight alleyway to assess the partial reinforcement extinction effect (PREE). There were four groups: one partial reinforcement group trained using a random schedule (RA), two partial groups for which reinforcement ratios were gradually increased (GI) or decreased (GD), and a continuous reinforcement group (CR). They showed significant acquisition and extinction effects. The CR group was the most resistant to extinction, with no significant difference among the other three. The results indicate a reverse PREE in newts, and suggest that their learning is controlled mainly by a simple Strengthening-Weakening mechanism.
