Pigeons were trained to key peck on several multiple schedules in which the first of two components was always a simple fixed-interval schedule. The rate of responding at the beginning of the constant fixed-interval schedule was found to decrease with increases in the rate of reinforcement associated with the other component of the multiple schedule, but remained unchanged with decreases in the rate of responding associated with the other component. These results were interpreted as being consistent with the view that the presence and magnitude of the temporal inhibitory effects observed in a given fixed-interval schedule are a function of the properties of reinforcing stimuli, rather than of changes in the rate of responding associated with the time interval immediately preceding the fixed interval in question.
鸽子被训练在几个多重时间表上啄键,其中前两个组成部分总是一个简单的固定间隔时间表。在恒定固定间隔时间表的开始时,反应率被发现随着与多重时间表的另一组成分相关的强化率的增加而降低,但随着与另一组成分相关的反应率的降低而保持不变。这些结果被解释为与这样一种观点一致,即在给定的固定间隔时间表中观察到的时间抑制效应的存在和大小是强化刺激的属性的函数,而不是与正在讨论的固定间隔之前的时间间隔相关的反应率的变化的函数。
