在这项研究中，我们问到什么程度的半场有助于在基于对象的判断任务中观察到的注意力分散效果。如果两个半场中的物体识别过程是完全独立的，那么将刺激放置在单独的半场中将消除注意力分散效应;在另一个极端，如果两个半场中的物体识别过程是完全整合的，那么将刺激放置在单独的半场中将不会调节注意力分散效应。使用双任务范式，我们比较了在语义分类任务的相关刺激，安排在同一个半野的表现，安排在不同的左，右半野的相关刺激的表现。在两个实验中，有一个可靠的减少，分散注意力的效果时，刺激显示在单独的hemifields相比，相同的hemifields。然而，分散注意力的影响并没有消除。这些结果拒绝独立和综合的假设，而是支持第三种选择-在两个hemifields的对象识别过程是部分依赖的。更具体地说，调制的幅度由hemifields是更接近的预测的综合假设，这表明，对于双任务的对象，依赖性的处理主要是共享整个视野。
In this study, we asked to what degree hemifields contribute to divided attention effects observed in tasks with object-based judgments. If object recognition processes in the two hemifields were fully independent, then placing stimuli in separate hemifields would eliminate divided attention effects; in the alternative extreme, if object recognition processes in the two hemifields were fully integrated, then placing stimuli in separate hemifields would not modulate divided attention effects. Using a dual-task paradigm, we compared performance in a semantic categorization task for relevant stimuli arranged in the same hemifield to performance for relevant stimuli arranged in separate left and right hemifields. In two experiments, there was a reliable decrease in divided attention effects when stimuli were shown in separate hemifields compared to the same hemifield. However, the effect of divided attention was not eliminated. These results reject both the independent and integrated hypotheses, and instead support a third alternative – that object recognition processes in the two hemifields are partially dependent. More specifically, the magnitude of modulation by hemifields was closer to the prediction of the integrated hypothesis, suggesting that for dual tasks with objects, dependent processing is mostly shared across the visual field.
