Six pigeons were trained to reproduce two-event sequences in an experiment that employed a discrete-trial procedure that required subjects to peck one of four possible sample sequences (left-left, left-right, right-right, right-left) signaled on a given trial by the successive illumination of response keys. Following a retention interval (0.1 to 30 seconds), a reinforcer was delivered if a subject reproduced the prior sample sequence during a test condition in which both left and right keys were illuminated. The pigeons readily reproduced the orders in which they had just seen and pecked two illuminated keys. Reproduction accuracy declined as the retention interval was increased. Homogeneous sequences (left-left, right-right) were reproduced with greater accuracy than heterogeneous sequences.
在一项实验中，六只鸽子接受训练以重现两事件序列。该实验采用离散试验程序，要求受试者啄四个可能的样本序列（左 - 左、左 - 右、右 - 右、右 - 左）中的一个，在给定试验中，响应键的连续照明表示这些序列。经过一个保留间隔（0.1至30秒）后，如果受试者在测试条件下（左右键均亮起）重现先前的样本序列，则给予强化物。鸽子很容易重现它们刚刚看到并啄过的两个亮起键的顺序。随着保留间隔的增加，重现准确性下降。同质序列（左 - 左、右 - 右）的重现准确性高于异质序列。
