Five experiments examined preferences for horizontal positions in multiobject pictures. In Experiment 1, each picture contained a fixed object and an object whose position could be adjusted to create the most (or least) aesthetically pleasing image. Observers placed the movable object closer to the fixed object when the objects were related than when they were unrelated (a relatedness bias) but almost never overlapped them (a separation bias). Experiment 2 showed that these results were not due to demand characteristics by replicating them almost exactly in a between-participants design. In Experiment 3, preference rankings revealed a strong relatedness bias together with an inward bias toward the spatial envelope of objects to point into the frame. A weak balance effect was evident in a multiple regression analysis. Experiment 4 replicated the inward bias for the spatial envelope using multiobject groups. Experiment 5 generalized the above findings for different objects when observers had to choose between image pairs that differed only in interobject distance or degree of balance. Strong relatedness effects were again present, but there was no evidence of any preference for balance.
五项实验研究了多物体图片中对水平位置的偏好。在实验1中，每张图片包含一个固定物体和一个位置可调整的物体，以创造出最（或最不）美观的图像。当物体相关时，观察者会将可移动物体放置得比不相关时更靠近固定物体（相关性偏差），但几乎从不使它们重叠（分离偏差）。实验2通过在被试间设计中几乎完全重复这些结果，表明这些结果并非由需求特征导致。在实验3中，偏好排名显示出强烈的相关性偏差以及朝向物体空间包络向内指向画面框架的偏差。多元回归分析中明显存在微弱的平衡效应。实验4使用多物体组重复了对空间包络的向内偏差。实验5将上述发现推广到不同物体上，当观察者必须在仅物体间距离或平衡程度不同的图像对之间进行选择时。再次出现了强烈的相关性效应，但没有证据表明对平衡有任何偏好。
