Pigeons rapidly acquired a discrimination between 40 pictures containing trees and 40 not containing trees. Differential reinforcement did not affect the discriminability of individual instances of trees. Generalization to new instances of tree pictures was better than to new instances of non-tree pictures. The level of discrimination did not depend on whether trees constituted the reinforced or the unreinforced category.
鸽子迅速学会了区分40张包含树木的图片和40张不包含树木的图片。差别强化并不影响树木个体实例的可辨别性。对树木图片新实例的泛化能力优于对非树木图片新实例的泛化能力。辨别水平并不取决于树木是构成强化类别还是非强化类别。
