Inflexibility of mental planning processes has repeatedly been discussed to represent a specific disorder resulting from human frontal lobe lesions. Patient groups suffering from acute or chronic unilateral frontal (medial, lateral) or retrorolandic (temporal, parietal) lesions and nonbrain-damaged controls were requested to mirror and to reverse mentally a maze structure that had been learned by the covered maze presentation technique (KARNATH et al., Neuropsychologia 29, 271-290, 1991). The patients with acute frontal lesions were impaired to adapt the acquired mental plan to the new (but related) problem and made more errors than those with acute temporal or parietal lesions and controls. However, no impaired plan modification was detected in patients with chronic frontal brain lesions. The difference of task performance in the acute and chronic (recovered) stage of frontal brain damage is discussed.
心理规划过程的灵活性不足反复被讨论为一种由人类额叶损伤导致的特定障碍。要求患有急性或慢性单侧额叶(内侧、外侧)或罗兰后区(颞叶、顶叶)损伤的患者组以及无脑损伤的对照组,在脑海中镜像并反转一个通过覆盖迷宫呈现技术(卡尔纳特等人,《神经心理学》29卷,271 - 290页,1991年)学会的迷宫结构。急性额叶损伤患者在使习得的心理计划适应新的(但相关的)问题方面存在障碍,且比急性颞叶或顶叶损伤患者及对照组犯更多错误。然而,在慢性额叶脑损伤患者中未检测到计划修改受损。文中讨论了额叶脑损伤急性和慢性(恢复)阶段任务表现的差异。
