Abstract

Intensity discrimination thresholds for 500-ms pure-tone bursts were measured as a function of frequency in the goldfish (Carassius auratus) using classical respiratory conditioning. At 55-dB sensation level (SL), thresholds range from 1.44-2.2 dB between 100 and 1600 Hz. There is not important effect of frequency on intensity discrimination. Thresholds at 35-dB SL average 0.7 dB higher than at 55-dB SL. This is a small difference in the context of the threshold variability. In intensity discrimination acuity, the goldfish is quantitatively similar to other vertebrates, including birds and mammals.

摘要

使用经典呼吸条件反射，测量了金鱼（Carassius auratus）中500毫秒纯音脉冲的强度辨别阈值随频率的变化。在55分贝感觉级（SL）时，100至1600赫兹之间的阈值范围为1.44至2.2分贝。频率对强度辨别没有重要影响。35分贝SL时的阈值平均比55分贝SL时高0.7分贝。在阈值变异性的背景下，这是一个小差异。在强度辨别敏锐度方面，金鱼在数量上与包括鸟类和哺乳动物在内的其他脊椎动物相似。
