Barela (Psychological Reports, 110: 173-186, 2012) presented a novel preparation for the experimental study of classical fear conditioning in goldfish, and successfully employed it in the demonstration of several basic conditioning principles. The present research addressed some basic methodological questions using a modified version of this preparation. Results indicated that the modification made to the visual CS increased its efficacy, and that conditioning to this stimulus was directly related to the number of CS-US trials given, US intensity, and intertrial interval. In addition, conditioning was detected with interstimulus intervals both shorter and longer than those used previously, as well as with an auditory CS. Methodological implications for the future employment of this preparation are discussed.
巴雷拉（《心理报告》，第110卷：173 - 186页，2012年）提出了一种用于金鱼经典恐惧条件反射实验研究的新方法，并成功地将其用于证明几个基本的条件反射原理。本研究使用该方法的修改版本解决了一些基本的方法论问题。结果表明，对视觉条件刺激（CS）所做的修改提高了其效力，并且对该刺激的条件反射与所给予的条件刺激 - 无条件刺激（CS - US）试验次数、无条件刺激强度和试验间隔直接相关。此外，在刺激间隔比之前使用的更短和更长的情况下以及使用听觉条件刺激时都检测到了条件反射。讨论了该方法在未来应用中的方法论意义。
