本研究使用调整量程序检验了Long-Evans大鼠（n = 8）反应偏倚对延迟折扣测量的贡献。在此程序下，我们评估了延迟交付150 μl 10%蔗糖溶液的偏好，而不是立即交付可变量的替代方案。当强化物从两个备选方案中立即交付时，根据相对偏好计算偏差。除了评估传统的延迟贴现函数外，我们还扩展了这一评估程序，以检查当两个备选方案的奖励均延迟（2、4、8或16秒）时的偏好。不同延迟的相对偏好相似，且略大于150 μl。这些结果表明，反应偏差是稳定的，并且表明对调整选项的相对厌恶，这可能是由于与该选项相关的奖励大小的可变性。
This study examined the contribution of response bias to measures of delay discounting in Long-Evans rats (n = 8) using the adjusting amount procedure. Under this procedure, we assessed preference for 150 μl of 10% sucrose solution delivered following a delay over a variable-amount alternative delivered immediately. Bias was calculated based on relative preference when reinforcers were delivered immediately from both alternatives. We extended this assessment procedure to examine preference when rewards from both alternatives were equally delayed (2, 4, 8, or 16 s) in addition to assessing a traditional delay discounting function. Relative preference was similar across delays and slightly larger than 150 μl. These results indicate that response bias was stable and suggests a relative aversion for the adjusting alternative, which may be due to the variability in reward size associated with that alternative.
