Studies of the immediate verbal imitations (IVIs) of subjects with echolalia report that features of linguistic or social input alone affect the number of IVIs elicited. This experimental study of a child with echolalia and autism controlled each of these variables while introducing a systematic change in the other. The subject produced more (p less than .05) IVIs in response to unknown lexical words presented with a high degree of directiveness (Condition D) than in response to three other conditions of stimulus presentation (e.g., unknown lexical words, minimally directive style.) Thus, an interaction between the effects of linguistic and social input was demonstrated. IVIs were produced across all conditions, primarily during first presentations of lexical stimuli. Only the IVIs elicited by first presentations of the lexical stimuli during Condition D differed significantly (p less than .05) from the number of IVIs elicited by first presentations of lexical stimuli in other conditions. These findings viewed together suggest that the occurrence of IVIs was related, at least for this child, to an uncertain or informative event and that this response was significantly greater when the lexical stimuli were unknown and presented in a highly directive style.
对有模仿言语的受试者的即时言语模仿（IVIs）研究报告称，仅语言或社会输入的特征就会影响引发的IVIs数量。这项针对一名有模仿言语和自闭症儿童的实验研究，在对其中一个变量进行系统性改变的同时，对这些变量中的每一个都进行了控制。与对其他三种刺激呈现条件（例如，未知词汇、极低指示性风格）的反应相比，该受试者对具有高度指示性呈现的未知词汇（条件D）产生了更多（p小于0.05）的IVIs。因此，证明了语言和社会输入效应之间的相互作用。在所有条件下都会产生IVIs，主要是在词汇刺激的首次呈现期间。只有在条件D下词汇刺激首次呈现引发的IVIs与其他条件下词汇刺激首次呈现引发的IVIs数量有显著差异（p小于0.05）。综合来看，这些发现表明，至少对这个孩子来说，IVIs的出现与一个不确定或信息丰富的事件有关，并且当词汇刺激未知且以高度指示性风格呈现时，这种反应会明显更大。
