Two pigeons matched to sample on the basis of color or line orientation when a sample consisted of a value for each stimulus dimension or a value for only one dimension. When the duration of the sample stimulus was varied to maintain constant performance, compound stimuli required more time than single elements.
当样本由每个刺激维度的值或只有一个维度的值组成时,两只鸽子根据颜色或线条方向与样本匹配。当样本刺激的持续时间变化以保持恒定的表现时,复合刺激比单一元素需要更多的时间。
