The location of the reward mountain along the price axis.

The “ Drg” and “ Veh” columns list the estimated values that the parameter would have attained in the drug and vehicle conditions, respectively, had frequency following been perfect. The “diff” column shows the differences between the estimates for the drug and vehicle conditions, whereas the “diff Lo” and “diff Hi” columns designate the lower and upper bounds of the 95% confidence interval surrounding these differences. The ⋆ character in the “excl 0” column indicates that zero falls outside the 95% confidence interval surrounding the estimates in the“diff” column. Differences so designated meet our criterion for statistical reliability. The rightmost column lists the proportional drug-induced change in the value of corresponding to the values in the “diff” column. ().

"Drg"列与"Veh"列分别列出了药物组与溶媒组条件下，若频率追随效应完全显现时，对应参数所能达到的估计值。"diff"列展示了药物组与溶媒组估计值的差值；"diff Lo"与"diff Hi"列分别标注了上述差值对应的95%置信区间的下限与上限。"excl 0"列中的星号（⋆）表明，"diff"列对应估计值的95%置信区间未包含0值。标注有该星号的差值符合本研究设定的统计学可靠性标准。最右侧列列出了与"diff"列数值相对应的药物诱导比例变化量。()
