描述了用454只白化雄性查尔斯河大鼠进行的3次实验。比较了电离辐射和氯化锂诱导的条件味觉厌恶的正向（CS-UCS，条件刺激-非条件刺激）和后向（UCS-CS）条件反射范式。当糖精CS在100 r辐射UCS之前或之后长达6小时（但体重的2%）时，会产生味觉厌恶。15 mol LiCl UCS仅在CS-UCS配对中有效。有人认为，在UCS-CS配对中，LiCl刺激的无效不是由于各自的LiCl和辐射剂量的“强度”的差异，因为这些剂量在正向配对中产生了相当的厌恶。这些结果与味觉厌恶条件反射的“疾病”模型的不足有关。（22 ref）（PsycINFO Database Record (c) 2016 APA，版权所有）
Describes 3 experiments with a total of 454 albino male Charles-River rats. Conditioned taste aversions induced by ionizing radiation and lithium chloride (LiCl) were compared with both forward (CS-UCS, conditioned stimulus-unconditioned stimulus) and backward (UCS-CS) conditioning paradigms. Taste aversions were produced when a saccharin CS preceded or followed a 100-r radiation UCS by as much as 6 hrs, but a 2%-of-body-weight,. 15-mol LiCl UCS was effective only in CS-UCS pairings. It is argued that the ineffectiveness of an LiCl stimulus in UCS-CS pairings was not attributable to differences in the" strength" of the respective LiCl and radiation doses in that these doses yielded comparable aversions in forward pairings. These results are related to inadequacies of a" sickness" model of taste aversion conditioning.(22 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
