Abstract
Preference for constant and mixed delay of reinforcement was studied using concurrent equal variable-interval schedules. For four pigeons, pecking one key was reinforced following constant delays of 8 sec and mixed delays of 6 or 10 and 2 or 14 sec. Pecking a second key was reinforced following constant delays of 0, 8, 16, and 32 sec. For two additional pigeons, pecking one key was reinforced following delays of 30, 15 or 45, 5 or 55, and 0 or 60 sec. Reinforcements on the other key were delayed 30 sec. It was found that (a) pigeons preferred mixed relative to constant delay of reinforcement, and (b) preference for mixed delay of reinforcement increased as the range of delay interval variability increased.
摘要
使用同时等变间隔程序，研究了对固定时距和变化时距强化的偏好。对于四只鸽子，啄一个键在固定时距 8 秒和变化时距 6 或 10 和 2 或 14 秒后得到强化。啄第二个键在固定时距 0、8、16 和 32 秒后得到强化。对于另外两只鸽子，啄一个键在变化时距 30、15 或 45、5 或 55 和 0 或 60 秒后得到强化。另一个键的强化则延迟 30 秒。结果发现：（a）鸽子相对于固定时距强化更喜欢变化时距强化；（b）随着延迟间隔变化范围的增加，对变化时距强化的偏好也增加。
