Words with mixed uppercase and lowercase letters (e.g. fAdE) were perceived more accurately than mixed-case pseudowords (e.g. gAdE), and mixed-case pseudowords were perceived more accurately than mixed-case unrelated letter strings (e.g. eFdT). In addition, same-case words were perceived more accurately than their mixed-case counterparts. The same held true for pseudowords but not for unrelated letter strings. The results are compatible with the view that both letter identify and visual form information are used in word perception.
大小写混合的单词（如fAdE）比大小写混合的伪词（如gAdE）被感知得更准确，而大小写混合的伪词比大小写混合的不相关字母串（如eFdT）被感知得更准确。此外，全大写或全小写的单词比其大小写混合的对应词被感知得更准确。伪词的情况也是如此，但不相关字母串并非如此。这些结果与单词感知中同时使用字母识别和视觉形式信息的观点一致。
