Nine patients with left-sided neglect and nine matched control patients performed three tasks on horizontal (either normal or mirror-reversed) letter strings. The tasks were: reading aloud, making a lexical decision (word vs non-word), and making a semantic decision (living vs non-living item). Relative to controls, neglect patients performed very poorly in the reading task, whereas they performed nearly normally in the lexical and semantic tasks. This was considered to be a dissociation between direct tasks, rather than a dissociation between explicit and implicit knowledge. The explanation offered for the dissociation is in terms of both a dual-route model for reading aloud and a degraded representation of the letter string.
九名患有左侧忽视症的患者和九名匹配的对照患者对水平排列（正常或镜像反转）的字母串执行三项任务。这些任务分别是：大声朗读、进行词汇判断（单词与非单词）以及进行语义判断（有生命的物品与无生命的物品）。与对照组相比，忽视症患者在朗读任务中表现很差，而在词汇和语义任务中表现几乎正常。这被认为是直接任务之间的分离，而不是显性知识和隐性知识之间的分离。针对这种分离给出的解释涉及大声朗读的双通路模型以及字母串表征的退化。
