一系列研究表明，当要匹配的字母对被投射到两个半球而不是一个半球时，反应会更快。这里描述的四个实验测试了这种双边领域的优势，并确定了影响其程度的因素。向受试者展示从集合“AaBb”中抽取的字母对，如果字母具有相同的名称（无论大小写），则将字母对分类为“匹配”，如果不具有相同的名称，则将字母对分类为“不匹配”。在前两个实验中，字母对是单侧呈现的（两个字母都在一个视野中），双侧（每个视野中一个字母，或中央（两个字母都在垂直中线上，在注视上方和下方），为了研究屏幕位置对双侧视野优势的影响，实验三增加了一个双侧对角位置（检查水平扫描策略相关的伪影），第四个实验增加了分心物数字（等同于双侧和单侧条件下的初始处理需求）.结果表明，双侧场优势是一个鲁棒的现象，尽管几个操作降低了其幅度。这些研究结果的影响模型的半球合作和半球间的处理进行了讨论。
A series of studies have reported that responding is faster when letter pairs to be matched are projected to two hemispheres rather than one. Four experiments described here tested this bilateral field advantage and identified factors that influence its extent. Subjects were shown letter pairs drawn from the ensemble “AaBb”, and classified the letter pairs as “Match” if the letters had the same name (regardless of case) and “No Match” if they did not. In the first two experiments the letter pairs were presented unilaterally (both letters in one visual field), bilaterally (one letter in each visual field, or centrally (both letters on the vertical midline, above and below fixation), in order to investigate how the bilateral field advantage is influenced by screen location.The third experiment added a bilateral-diagonal position (to check for artefacts related to horizontal scanning strategies), and the fourth experiment added distractor digits (to equate initial processing demands in the bilateral and unilateral conditions).Results indicate that the bilateral field advantage is a robust phenomenon, although several manipulations reduced its magnitude. Implications of these findings for models of hemispheric collaboration and interhemispheric processing are discussed.
