Research examining the relationship between spontaneous and imitated productions for phonological analysis has indicated that the inclusion of imitated productions may overestimate children's phonological abilities. Previous research in this area has included only English-speaking children. The purpose of this study was to determine what, if any, differences there were in the spontaneous and imitated productions of Spanish-speaking children with phonological disorders.
Twelve Spanish-speaking children with phonological disorders (5 boys and 7 girls), ranging in age from 3;1 (years;months) to 4;9 (M = 3;11), participated in the study. Their spontaneous and imitated productions, based on a sample of single words, were analyzed to determine which elicitation task yielded the more adult-like production. Differences in consonant accuracy between the two tasks were analyzed, as was the shift in error type from spontaneous to imitated productions.
The results indicated that spontaneous and imitated productions were identical in 62% of the cases, an imitated production was more adult-like than a spontaneous one in 25% of the cases, and a spontaneous form was more adult-like than an imitated one in approximately 13% of the cases. Consonant accuracy for some children also varied as a function of elicitation task.
For additional diagnostic and prognostic value, speech-language pathologists can incorporate imitated responses in their analyses.
研究自发产出与模仿产出之间的关系以进行语音分析，结果表明纳入模仿产出可能会高估儿童的语音能力。该领域之前的研究仅纳入了说英语的儿童。本研究的目的是确定患有语音障碍的说西班牙语儿童的自发产出与模仿产出之间是否存在差异（若有差异，则确定差异为何）。
12名患有语音障碍的说西班牙语儿童（5名男孩和7名女孩）参与了该研究，年龄范围为3;1（岁;月）至4;9（平均年龄 = 3;11）。基于单词语样本，对他们的自发产出和模仿产出进行分析，以确定哪种引出任务能产生更接近成人的产出。分析了两项任务之间辅音准确性的差异，以及从自发产出到模仿产出错误类型的转变。
结果表明，在62%的情况下，自发产出和模仿产出是相同的；在25%的情况下，模仿产出比自发产出更接近成人；在约13%的情况下，自发形式比模仿形式更接近成人。一些儿童的辅音准确性也因引出任务而异。
为获得更多诊断和预后价值，言语病理学家可在分析中纳入模仿反应。
