Three pigeons were trained to peck two to five illuminated response keys. A peck to any of the keys changed the stimulus on the key. When all keys showed the same stimulus (i.e., a stimulus match), an additional key was illuminated with white light. A peck on this key produced three-second access to grain, a three-second intertrial interval, and the next trial. For most sessions, no particular stimulus match was required. Although there were often several stimuli available, each bird preferred a particular stimulus match. With up to 12 stimuli available, birds matched a particular stimulus 60% to 100% of the time.
训练了三只鸽子去啄两到五个亮起的反应键。啄其中任何一个键都会改变该键上的刺激。当所有键都显示相同的刺激（即刺激匹配）时，另一个键会亮起白光。啄这个键会有三秒钟的时间获取谷物，三秒钟的试验间隔，然后进入下一次试验。在大多数试验中，不需要特定的刺激匹配。虽然通常有几种刺激可供选择，但每只鸟都偏爱一种特定的刺激匹配。有多达12种刺激可供选择时，鸟类在60%到100%的时间里会匹配特定的刺激。
