两个实验进行了，以检查的功能步骤的好处，半球间整合的影响。实验1的目的是研究Banich（1995 a）模型的有效性，即随着任务涉及更多的功能步骤，半球间加工的益处增加。16名右利手的被试被给予两种类型的平假名-片假名脚本匹配任务。一个是姓名识别（NI）任务，另一个是元音匹配（VM）任务，它涉及更多的功能步骤相比，NI任务。VM任务要求受试者决定一对片假名-平假名脚本是否有共同的元音。在这两项任务中，一对假名脚本（片假名-平假名脚本）速示呈现在单侧视野或双侧视野，其中每个字母在每个视野中呈现。双侧视野优势（BFA）被发现在这两项任务中，并没有不同的任务，这表明这些发现并不支持Banich模型的大小。实验二的目的是研究两半球之间不平衡的加工负荷对两半球整合的影响。为了控制两半球加工负荷的平衡，我们对元音匹配任务进行了改进，发展了一个新的元音匹配任务。的r-VM的任务是相同的VM任务在实验1中，除了一个脚本，只有元音的声音作为一对假名脚本的对应物。24名右利手受试者被给予r-VM和NI任务。结果表明，尽管在NI任务中出现了BFA，但在r-VM任务中没有出现。这些结果表明，两半球加工负荷的平衡会对双侧半球的加工产生影响。
Two experiments were carried out in order to examine the effects of functional steps on the benefits of interhemispheric integration. The purpose of Experiment 1 was to investigate the validity of the Banich (1995a) model, where the benefits of interhemispheric processing increase as the task involves more functional steps. The 16 right-handed subjects were given two types of Hiragana-Katakana script matching tasks. One was the Name Identity (NI) task, and the other was the vowel matching (VM) task, which involved more functional steps compared to the NI task. The VM task required subjects to make a decision whether or not a pair of Katakana-Hiragana scripts had a common vowel. In both tasks, a pair of Kana scripts (Katakana-Hiragana scripts) was tachistoscopically presented in the unilateral visual fields or the bilateral visual fields, where each letter was presented in each visual field. A bilateral visual fields advantage (BFA) was found in both tasks, and the size of this did not differ between the tasks, suggesting that these findings did not support the Banich model. The purpose of Experiment 2 was to examine the effects of imbalanced processing load between the hemispheres on the benefits of interhemispheric integration. In order to manipulate the balance of processing load across the hemispheres, the revised vowel matching (r-VM) task was developed by amending the VM task. The r-VM task was the same as the VM task in Experiment 1, except that a script that has only vowel sound was presented as a counterpart of a pair of Kana scripts. The 24 right-handed subjects were given the r-VM and NI tasks. The results showed that although a BFA showed up in the NI task, it did not in the r-VM task. These results suggested that the balance of processing load between hemispheres would have an influence on the bilateral hemispheric processing.
