本研究评估了额叶损伤患者的时间顺序记忆缺陷是由于时间信息自动编码受损还是继发于努力过程的缺陷，如组织策略的使用和干扰控制。对背外侧前额叶皮层病变患者和对照组进行了语义学相关词表和非语义学不相关词表的时间顺序重建测试；故意的或偶然的情况额叶病变患者的时间顺序记忆对语义相关性敏感，而对学习意图不敏感。使用类似编码操作的无项目回忆和识别测试表明，这些患者的顺序表现与项目记忆是分离的。结果表明，额叶病变患者对颞叶信息的自动处理完好无损，但对该信息的策略处理受损。
This study evaluated whether deficits in memory for temporal order in patients with frontal lobe lesions result from impaired automatic encoding of temporal information or are secondary to deficits in effortful processes, such as the use of organizational strategies and control of interference. Patients with lesions in the dorsolateral prefrontal cortex and control participants were tested on temporal order reconstruction of semantically related and unrelated word lists learned ur;der intentional or incidental conditions. Memory for temporal order in patients with frontal lobe lesions was sensitive to semantic relatedness but not to intention to learn. Tests of item free recall and recognition using similar encoding manipulations indicated that order performance in these patients was dissociable from item memory. Results indicate that automatic processing of temporal information is intact in patients with frontal lobe lesions but that strategic processing of this information is impaired.
