早期的研究报告称，左半球受损的受试者保留了公式化语言，而右半球受损的中风患者在对话中公式化表达的发生率降低。临床观察表明，皮质下核也可能发挥作用。本研究探讨了在自发言语的中风患者的公式化语言与左，右，或皮质下损伤。四个主题进行了采访，他们的语音样本相比，正常的发言者。评分者将公式化表达分为言语公式、填充语、句干和专有名词。结果表明，大脑损伤影响小说和公式化的语言能力不同，公式化的表达在右或皮质下损伤的受试者相比，左半球受损或健康的扬声器的比例显着较小。这些发现与以前的研究，支持建议的右半球/皮层下回路的公式化表达的管理，基于双过程模型的语言，将小说和公式化的语言使用。
Early studies reported preserved formulaic language in left hemisphere damaged subjects and reduced incidence of formulaic expressions in the conversational speech of stroke patients with right hemispheric damage. Clinical observations suggest a possible role also of subcortical nuclei. This study examined formulaic language in the spontaneous speech of stroke patients with left, right, or subcortical damage. Four subjects were interviewed and their speech samples compared to normal speakers. Raters classified formulaic expressions as speech formulae, fillers, sentence stems, and proper nouns. Results demonstrated that brain damage affected novel and formulaic language competence differently, with a significantly smaller proportion of formulaic expressions in subjects with right or subcortical damage compared to left hemisphere damaged or healthy speakers. These findings converge with previous studies that support the proposal of a right hemisphere/subcortical circuit in the management of formulaic expressions, based on a dual-process model of language incorporating novel and formulaic language use.
