混合XeD-cAsE刺激长期以来一直被用来测试单词识别是基于整体视觉信息还是基于初步的字母识别。然而，如果不知道混合情况下的刺激破坏处理的属性，它是不可能确定哪些视觉单位介导的单词识别。本研究考察了大小写混合对单词和非单词命名的影响，并将其作为（a）字母之间是否插入空格和（B）字母大小是否独立于字母大小写交替的函数。结果表明，混合破坏效果是由于至少2个因素：引入不适当的分组之间的字母相同的大小和情况下，和中断的transletter功能。这些数据支持基于多个视觉单元输入的视觉词汇访问模型。
MiXeD-cAsE stimuli have long been used to test whether word recognition is based on holistic visual information or preliminary letter identification. However, without knowing which properties of mixed-case stimuli disrupt processing, it is not possible to determine which visual units mediate word recognition. The present studies examined the effects of case mixing on word and nonword naming as a function of (a) whether spaces were inserted between letters and (b) whether letter size was alternated independent of letter case. The results suggest that case-mixing disruption effects are due to at least 2 factors: the introduction of inappropriate grouping between letters with the same size and case, and the disruption of transletter features. The data support a model of visual lexical access based on the input from multiple visually based units.
