Long-term recency effects were investigated in a left brain-damaged patient, PV, who had a pathologically low auditory-verbal span and a lack of the normal recency effects in immediate free recall of auditorily presented lists of words, attributed to the abnormally reduced capacity of the phonological short-term store component of memory (Vallar and Papagno, 1986). In a task requiring the delayed free recall of a list of anagram solutions the patient showed both a recall performance level and a long-term recency effect comparable to the control group. These findings dissociate long and short-term recency phenomena, which would reflect the operation of different memory components. A collateral finding was PV's difficulty in anagram solving, which may be traced back to the defective function of her phonological short-term store.
对一名左脑损伤患者PV进行了长期近因效应的研究。该患者听觉言语广度病理性降低，在对听觉呈现的单词列表进行即时自由回忆时缺乏正常的近因效应，这归因于记忆的语音短期存储成分能力异常降低（瓦拉尔和帕帕尼奥，1986年）。在一项要求对一组字谜答案进行延迟自由回忆的任务中，该患者表现出的回忆表现水平和长期近因效应与对照组相当。这些发现区分了长期和短期近因现象，这可能反映了不同记忆成分的运作。一个附带的发现是PV在解决字谜方面存在困难，这可能追溯到她语音短期存储的功能缺陷。
