Abstract

Responding to a related pair of measurements is often expressed as a single discrimination ratio. Authors have used various discrimination ratios; yet, little information exists to guide their choice. A second use of ratios is to correct for the influence of a nuisance variable on the measurement of interest. I examine 4 discrimination ratios using simulated data sets. Three ratios, of the form a/(a + b), b/(a + b), and (a - b)/(a + b), introduced distortions to their raw data. The fourth ratio, (b - a)/b largely avoided such distortions and was the most sensitive at detecting statistical differences. Effect size statistics were also often improved with a correction ratio. Gustatory sensory preconditioning experiments involved measurement of rats' sucrose and saline consumption; these flavors served as either a target flavor or a control flavor and were counterbalanced across rats. However, sensory preconditioning was often masked by a bias for sucrose over saline. Sucrose and saline consumption scores were multiplied by the ratio of the overall consumption to the consumption of that flavor alone, which corrected the bias. The general utility of discrimination and correction ratios for data treatment is discussed. (PsycINFO Database Record

比率和效应大小。
对一对相关测量结果的反应通常用一个判别率来表示。作者们使用了各种不同的区分度比值;然而,几乎没有任何信息可以指导他们的选择。比率的第二种用途是纠正干扰变量对相关测量的影响。我使用模拟数据集研究了 4 种区分度比率。三个比率,即 a/(a + b)、b/(a + b)和 (a - b)/(a + b),对原始数据造成了扭曲。第四种比率 (b - a)/b 在很大程度上避免了这种失真,而且在检测统计差异方面最为灵敏。修正比值通常也能改善效应大小统计。味觉预调实验包括测量大鼠的蔗糖和生理盐水消耗量;这些味道可作为目标味道或对照味道,并在不同大鼠之间进行平衡。然而,感官预调通常会被蔗糖而非生理盐水的偏好所掩盖。蔗糖和生理盐水的消耗量得分乘以总体消耗量与单独消耗该味道的比率,就能纠正偏差。本文讨论了数据处理中辨别率和校正率的一般用途。(PsycINFO数据库记录
