Abstract: | Two groups of pigeons received differential discrimination training on the presence vs absence of a vertical line on a white surround. The line was green for one group and black for a second group. Generalization tests along the angularity dimension showed that both green and black lines produced equally steep gradients. The results suggested that the addition of chroma to the line does not increase attention to the line. |
