Abstract

In experiment 1, five goldfish (Carassius auratus) paddle-pressed on fixed-interval (FI) and variable-interval (VI) schedules for food pellet reinforcement. The order of conditions was FI 60 s, FI 240 s, FI 30 s, FI 60 s, and VI 60 s. FI responding showed a scalloped pattern and response-rate break points were proportional to interval duration. Post-food wait times varied with interval duration, but were not proportional. Response rate on VI was constant. Experiment 2 studied the properties of food reinforcement as a time marker. The same five fish were presented an FI 60 s schedule of reinforcement with 25% of intervals ending in non-reinforcement (N). The fish responded faster and paused less following the omission stimulus (omission effect) and response rate was flat or declined through post-N intervals.

摘要

在实验1中，五条金鱼（Carassius auratus）根据固定间隔（FI）和可变间隔（VI）时间表按压桨叶以获取食物颗粒强化。条件顺序为FI 60秒、FI 240秒、FI 30秒、FI 60秒和VI 60秒。FI反应呈现出扇形模式，反应率断点与间隔持续时间成正比。食物后等待时间随间隔持续时间而变化，但不成比例。VI上的反应率是恒定的。实验2研究了作为时间标记的食物强化特性。对相同的五条鱼呈现FI 60秒的强化时间表，其中25%的间隔以无强化（N）结束。鱼在遗漏刺激后反应更快且停顿更少（遗漏效应），并且在N后的间隔中反应率持平或下降。
