摘要:
Pigeons were exposed to an ascending series of small fixed‐ratio schedules from fixed‐ratio 1 to 7. Two of those pigeons were later placed on a fixed‐ratio 30 schedule. The two primary dependent variables were the postreinforcement pause and the interresponse time. Changes in these variables under small fixed ratios were sometimes opposite to changes reported with large fixed ratios. For example, postreinforcement pauses decreased in length as the fixed‐ratio requirement increased from fixed‐ratio 1 to fixed‐ratio 3. Also, the interresponse times early in the small fixed‐ratio schedule were shorter than those immediately preceding reinforcement. These findings question the role of interresponse‐time reinforcement in determining temporal patterns of responding under small fixed‐ratio schedules. They also suggest that there may be a limited region in which the independent variable, fixed‐ratio size, does not operate as p
