Eight pigeons were trained on a go-no go visual discrimination involving 1 S+ and 15 S- s. The 16 discriminative stimuli were black-and-white line drawings created by the factorial combination of 4 different geometric shapes (wedge, cylinder, cone, handle) in 4 different spatial locations (right, left, above, below) in relation to a common shape (cube). All of the pigeons readily learned this complex visual discrimination. Each bird's pecking behavior was controlled by both attributes of the line drawings, but somewhat stronger stimulus control was exerted by the location of the added component than by its shape. Across all 8 pigeons, there was an inverse relation between stimulus control by component shape and component location. These results document pigeons' joint processing of "what" and "where" information in visual discrimination learning.
八只鸽子接受了一项“去-不去”视觉辨别训练，其中涉及1个正性刺激（S+）和15个负性刺激（S-）。这16种辨别刺激是由4种不同几何形状（楔形、圆柱体、圆锥体、把手）与一个共同形状（立方体）在4个不同空间位置（右、左、上、下）进行因子组合而生成的黑白线条图。所有鸽子都轻松学会了这种复杂的视觉辨别。每只鸽子的啄击行为都受线条图的两种属性控制，但附加成分的位置比其形状施加的刺激控制更强一些。在所有8只鸽子中，成分形状的刺激控制与成分位置之间存在反比关系。这些结果证明了鸽子在视觉辨别学习中对“什么”和“哪里”信息的联合处理。
