Comprehension of spoken Standard English was measured via a picture selection task for 80 Black English (BE) speaking and 80 Standard English (SE) speaking children at four age levels between 5 years, 6 months, and 9 years, 6 months. Test stimuli consisted of four syntactically matched groups of eight sentences divided into two levels of difficulty. The four groups of sentences were heard by all Ss at four different speaking rates from 4.9 (fast) through 2.5 (slow) syllables per second. Results showed that BE speaking children had greater difficulty comprehending spoken SE than the SE speaking control Ss. Significant age and difficulty effects were found for both groups; a significant rate effect was found for the BE speaking group only; and sentence difficulty was found to interact differently with age for the two groups.
通过一项图片选择任务，对80名说黑人英语（BE）和80名说标准英语（SE）的儿童在5岁6个月至9岁6个月的四个年龄阶段的标准英语口语理解能力进行了测量。测试刺激由四组句法匹配的句子组成，每组八个句子，分为两个难度级别。所有受试者以每秒4.9个（快速）到2.5个（慢速）音节的四种不同语速听到这四组句子。结果表明，说黑人英语的儿童比说标准英语的对照组受试者在理解标准英语口语方面有更大的困难。两组均发现显著的年龄和难度效应；仅在说黑人英语的组中发现显著的语速效应；并且发现句子难度在两组中与年龄的相互作用不同。
