目的语义性痴呆（SD）患者存在自传体记忆（AM）损伤，但其损伤程度一直存在争议。根据一份报告（Westmacott, Leach, Freedman, & Moscovitch, 2001），当使用视觉线索而不是口头线索时，患者的表现更好；然而，该研究中使用的视觉线索（家庭照片）比在AM研究中通常使用的文字线索提供了更多的检索支持。在本研究中，我们试图解开检索支持和线索模态的影响。方法对5例SD患者和5例对照组的AMs进行文字、简单图片和气味提示。记忆是从童年、成年早期和成年早期提取的；他们根据细节水平和情节特异性进行评分。结果患者在所有时间和刺激方式下均出现损伤。在患者组中，文字和图片作为提示同样有效(Friedman检验；χ²= 0.25,p=。61)，而气味的效果不如文字和图片(文字vs.气味，χ²= 7.83,p=。005年;对于图片与气味，χ²= 6.18,p=。01)。两组均无时间梯度的证据(SD患者，χ²= 0.24,p=。89年;对于对照组，χ²< 2.07,p=。35)。结论：一旦将不同刺激方式的检索支持效应等同起来，就没有证据表明视觉线索比语言线索更有优势。嗅觉线索的更大损伤可能反映了支持嗅觉记忆的前颞区退化。（PsycINFO数据库记录(c) 2017 APA，版权所有）
ObjectiveIndividuals with semantic dementia (SD) have impaired autobiographical memory (AM), but the extent of the impairment has been controversial. According to one report (Westmacott, Leach, Freedman, & Moscovitch, 2001), patient performance was better when visual cues were used instead of verbal cues; however, the visual cues used in that study (family photographs) provided more retrieval support than do the word cues that are typically used in AM studies. In the present study, we sought to disentangle the effects of retrieval support and cue modality.MethodWe cued AMs of 5 patients with SD and 5 controls with words, simple pictures, and odors. Memories were elicited from childhood, early adulthood, and recent adulthood; they were scored for level of detail and episodic specificity.ResultsThe patients were impaired across all time periods and stimulus modalities. Within the patient group, words and pictures were equally effective as cues (Friedman test; χ²= 0.25, p=. 61), whereas odors were less effective than both words and pictures (for words vs. odors, χ²= 7.83, p=. 005; for pictures vs. odors, χ²= 6.18, p=. 01). There was no evidence of a temporal gradient in either group (for patients with SD, χ²= 0.24, p=. 89; for controls, χ²< 2.07, p=. 35).ConclusionsOnce the effect of retrieval support is equated across stimulus modalities, there is no evidence for an advantage of visual cues over verbal cues. The greater impairment for olfactory cues presumably reflects degeneration of anterior temporal regions that support olfactory memory.(PsycINFO Database Record (c) 2017 APA, all rights reserved)
