识别控制动物复杂多态图片分类的关键特征仍然是一个具有挑战性和重要的问题。为了实现这一目标，进行了实验，以隔离的属性控制的两个图片类别的鸽子。在一项去/不去的任务中训练小猪对鸟类和哺乳动物的黑色和白色线条图进行分类。然后，他们用这些类别的各种熟悉和新颖的样本进行测试，以检查控制这种分类的特征。这些测试表明鸽子是分离的，并使用动物图形的主轴方向作为区分每个类别的主要手段，尽管可能涉及其他类别和项目特定的线索。这种将分类刺激空间减少到几个视觉特征或维度的感知/认知可能是该物种处理复杂图像辨别问题的特征，并且是这种行为的理论解释的关键属性。(C)出版社：Elsevier B. V.
Identifying critical features that control categorization of complex polymorphous pictures by animals remains a challenging and important problem. Toward this goal, experiments were conducted to isolate the properties controlling the categorization of two pictorial categories by pigeons. Pigeons were trained in a go/no-go task to categorize black and white line drawings of birds and mammals. They were then tested with a variety of familiar and novel exemplars of these categories to examine the features controlling this categorization. These tests suggested the pigeons were segregating and using the principal axis of orientation of the animal figures as the primary means of discriminating each category, although other categorical and item-specific cues were likely involved. This perceptual/cognitive reduction of the categorical stimulus space to a few visual features or dimensions is likely a characteristic of this species' processing of complex pictorial discrimination problems and is a critical property for theoretical accounts of this behavior.
