Saccharin aversions were conditioned using ethanol (EtOH) in rats of different body weights. There was a nonuniform relation between EtOH dose (g/kg) and strength of conditioned taste aversion. Heavier rats learned stronger aversions at the same dose, and a weak dose (i.e., 1.0 g/kg) was effective only in heavier rats. It is suggested that rats be equated on body weight in studies of EtOH-induced taste aversion learning and in studies of EtOH preference.
在不同体重的大鼠中，使用乙醇（EtOH）诱发糖精厌恶反应。乙醇剂量（克/千克）与条件性味觉厌恶的强度之间存在不一致的关系。体重较重的大鼠在相同剂量下会产生更强的厌恶反应，而低剂量（即1.0克/千克）仅对体重较重的大鼠有效。建议在乙醇诱发味觉厌恶学习研究和乙醇偏好研究中，根据体重对大鼠进行匹配。
