我们最近报道，接受单侧颞叶切除术的患者，包括杏仁核和海马，在恐惧条件反射任务中表现出受损的习得（LaBar，LeDoux，Spencer，& Phelps，1995），表明情感记忆缺陷。在本文中，我们研究了这些患者在两个语言，情感记忆任务的表现，以确定这种赤字的程度。在实验1中，被试被要求回忆情绪和非情绪的话。在实验二中，被试被要求回忆嵌入在情感和非情感句子语境中的中性词。颞叶切除术的受试者和正常对照组都表现出对情感词的回忆增强（实验1）和对嵌入在情感句子语境中的中性词的回忆增强（实验2）。这些结果表明，在单侧颞叶切除术后的情绪记忆中看到的赤字是不是一个全球性的赤字，并可能仅限于特定的情况下，情绪影响记忆表现。关于当前研究和恐惧条件反射结果之间的差异的几个假设（LaBar等人，1995年）进行了讨论。(C)北京：科学出版社.
We recently reported that patients who had received unilateral temporal lobectomy, including the amygdala and hippocampus, show impaired acquisition in a fear conditioning task (LaBar, LeDoux, Spencer, & Phelps, 1995), indicating a deficit in emotional memory. In the present paper, we examined performance of these patients on two verbal, emotional memory tasks in an effort to determine the extent of this deficit. In Experiment 1, subjects were asked to recall emotional and non-emotional words. In Experiment 2, subjects were asked to recall neutral words which were embedded in emotional and non-emotional sentence contexts. Both temporal lobectomy subjects and normal controls showed enhanced recall for emotional words (Experiment 1) and enhanced recall for neutral words embedded in emotional sentence contexts (Experiment 2). These results suggest that the deficit seen in emotional memory following unilateral temporal lobectomy is not a global deficit and may be limited to specific circumstances where emotion influences memory performance. Several hypotheses concerning the discrepancy between the present studies and the fear conditioning results (LaBar et al., 1995) are discussed. (C) 1997 Academic Press.
