This study examined narrative discourse in 23 children, ages 6 to 8 years, who sustained a severe closed head injury (CHI) at least 1 year prior to assessment. Narratives were analyzed at multiple levels using language and information structure measures. Results revealed significant discourse impairments in the CHI group on all measures of information structure, whereas differences in the linguistic domain failed to reach significance. In addition, effects of age at injury and lateralization of lesion on discourse were considered. Although no significant differences were found according to age at injury, a consistent pattern of generally poorer discourse scores was found for the early injured group (< 5 years). With regard to lesion focus, the group findings were unimpressive. However, preliminary examination of individual CHI cases with relatively large lateralized lesions suggested that the late injured children may show the language-brain patterns reported in brain-injured adults, whereas early injured children may not.
本研究调查了23名6至8岁儿童的叙事话语，这些儿童在评估前至少1年遭受了严重的闭合性颅脑损伤（CHI）。使用语言和信息结构指标在多个层面分析叙事。结果显示，CHI组在所有信息结构指标上均存在显著的话语障碍，而语言领域的差异未达到显著水平。此外，还考虑了受伤时的年龄和损伤部位的偏侧化对话语的影响。虽然未发现受伤时年龄的显著差异，但早期受伤组（<5岁）的话语得分普遍较低，呈现出一致的模式。关于损伤部位，组内研究结果并不显著。然而，对具有相对较大偏侧化损伤的个别CHI病例的初步检查表明，晚期受伤儿童可能表现出脑损伤成人中报道的语言-脑模式，而早期受伤儿童可能不会。
