The purpose of this investigation was to examine the effects of age at onset of traumatic brain injury on the linguistic competence of children and adolescents who sustained closed head injuries (CHI) that cause diffuse brain damage. The Test of Language Competence-Expanded Edition (TLC-E), a standardized test of subtle language abilities, was administered to 20 children who sustained severe CHI. The study determined whether 10 subjects who experienced CHI at a pre-adolescent age (4 to 11 years) and 10 subjects who experienced CHI at an adolescent age (13 to 18 years) showed quantitative differences in linguistic competence as measured by the TLC-E Test. The language abilities of children in both groups were compared to determine whether there were trends in performance relative to age of onset or type of subtest. In addition, experimental subjects' performance was compared to the normative population used to standardize the TLC-E. Hypotheses were constructed according to separate developmental and pathophysiological perspectives.
本研究的目的是检验创伤性脑损伤发病年龄对遭受闭合性颅脑损伤（CHI）并导致弥漫性脑损伤的儿童和青少年语言能力的影响。对20名遭受严重CHI的儿童进行了语言能力扩展版测试（TLC-E），这是一项关于细微语言能力的标准化测试。该研究确定了10名在青春期前（4至11岁）经历CHI的受试者和10名在青春期（13至18岁）经历CHI的受试者在TLC-E测试所衡量的语言能力上是否存在数量差异。比较了两组儿童的语言能力，以确定相对于发病年龄或子测试类型是否存在表现趋势。此外，将实验对象的表现与用于标准化TLC-E的正常人群进行了比较。根据不同的发育和病理生理学观点构建了假设。
