在两个实验中，被命名的正常受试者短暂地展示了物体的图片，这些图片要么显示在注视的左边，要么展示在右边。可归因于半视野的净效应可以忽略不计：左侧视野中显示的图片的命名RTS降低了12毫秒，但右侧视野中显示的图片的错误率略低，为0.8%。在这两个实验中，都进行了第二组实验，以评估物体启动时是否会显示半视野效应。命名相同名称不同形状样本图片的RTS显著长于相同图片的RTS，从而证明启动的一个成分是视觉的，而不仅仅是语言或概念的，但对启动的半场效应不存在。考虑到左右半场差异较大的变量可能相互平衡和抵消的可能性(不太可能)，我们得出结论，无论是物体识别还是物体启动，都不存在差异半场效应。
In two experiments, normal subjects named briefly presented pictures of objects that were shown either to the left or to the right of fixation. The net effects attributable to hemifield were negligible: naming RTs were 12 msec lower for pictures shown in the left visual field but error rates were slightly lower, by 0.8%, for pictures shown in the right visual field. In both experiments, a second block of trials was run to assess whether hemifield effects would be revealed in object priming. Naming RTs to same name different shaped exemplar pictures were significantly longer than RTs for identical pictures, thus establishing that a component of the priming was visual, rather than only verbal or conceptual, but hemifield effects on priming were absent. Allowing for the (unlikely) possibility that variables with large differential left right hemifield effects may be balancing and cancelling each other out, we conclude that there are no differential hemifield effects in either object recognition or object priming.
