对发育性失语症患者和匹配的对照者进行了辨别（a）两个合成的元音-元音音节和（B）两个合成的辅音-元音音节的能力的检查。对于元音和辅音，当两个刺激的可辨别成分是短暂的（43毫秒），但未受损时，这些成分是95毫秒或更长的失语症受损。它的结论是，发展性失语症没有困难，在歧视过渡的听觉信息等，他们受损的歧视合成塞音完全是由于短暂的持续时间的可辨别的组件。
Developmental dysphasics and matched controls were examined for their ability to discriminate (a) two synthesized vowel-vowel syllables and (b) two synthesized consonant- vowel syllables. For both vowels and consonants, dysphasics were impaired when the discriminable components of the two stimuli were brief (43 msec) but unimpaired when these components were 95 msec or longer. It is concluded that developmental dysphasics have no difficulty in discriminating transitional auditory information as such and that their impaired discrimination of synthesized stop consonants is attributable solely to the brief duration of the discriminable components.
