The study examines acute, material-specific secondary memory performance in 26 patients with mild traumatic brain injury (MTBI) and 26 healthy controls, matched on demographic variables and indexes of crystallized intelligence. Neuropsychological tests were used to evaluate primary and secondary memory, executive functions, and verbal fluency. Participants were also tested on episodic memory tasks involving words, pseudowords, pictures of common objects, and abstract kaleidoscopic images. Patients showed reduced performance on episodic memory measures, and on tasks associated with visuospatial processing and executive function (Trail Making Test part B, semantic fluency). Significant differences between groups were also noted for correct rejections and response bias on the kaleidoscope task. MTBI patients' reduced performance on memory tasks for complex, abstract stimuli can be attributed to a dysfunction in the strategic component of memory process.
本研究考察了 26 名轻度创伤性脑损伤 (MTBI) 患者和 26 名健康对照者的急性、特定物质的次要记忆表现，这些对照者在人口统计学变量和晶体智力指标上与患者相匹配。神经心理学测试用于评估主要和次要记忆、执行功能和言语流畅性。参与者还接受了涉及单词、伪单词、常见物体图片和抽象万花筒图像的情节记忆任务测试。患者在情节记忆测量以及与视觉空间处理和执行功能相关的任务（Trail Making Test 部分 B、语义流畅性）上的表现均有所下降。在万花筒任务上，两组的正确拒绝率和反应偏差也存在显著差异。MTBI 患者对复杂、抽象刺激的记忆任务表现下降，这可归因于记忆过程策略成分的功能障碍。
