两个实验进一步测试了鸽子如何利用地标寻找位置的模型。向量和模型(cheng，1988)预测，当一个地标从通常的位置向一个方向移动时，鸟类S的搜索峰位可能会在该方向上移动，但不是在垂直方向上。施加在特定地标上的权重是根据鸟将搜索转移到地标移动的方向的程度来估计的。在实验中，鸟儿被训练去寻找一个目标，在它的两边各有一个近地标和一个远地标。在偶尔的测试中，一个或两个地标都会发生移位。结果显示，总体上，鸟类对较近的地标的权重大于较远的地标。与向量和模型的预测一致，没有一只鸟类在与地标移动方向垂直的方向上移动其搜索峰位。
Two experiments further tested a model of how pigeons used landmarks to find a location. The vector sum model (Cheng, 1988) predicts that when a landmark is shifted in one direction from its usual position, the bird''s peak place of search may shift in that direction, but not in the orthogonal direction. The weight placed on a particular landmark is estimated by the extent to which the bird shifts its searching in the direction of the landmark shift. In the experiments, birds were trained to find a goal with one near landmark and one far landmark on either side of it. On occasional tests, one or both landmarks were shifted. Results showed that on the whole, the birds weighted the nearer landmark more than the farther landmark. In conformity with the predictions of the vector sum model, no bird shifted its peak place of search in the direction orthogonal to the direction of landmark shift.
