本研究旨在调查顺行性遗忘患者的即时和延迟近期效应。为此，对一组健忘症患者样本和一组年龄匹配的健康受试者进行了单词列表立即回忆范式和由 Baddeley 和 Hitch 设计的程序的修改版本[注意力和表现，Erlbaum，NJ，1977]，用于在延迟回忆条件下引发近因效应。记忆消除揭示了立即回忆范例中完全正常的近因效应和延迟回忆条件下的缺陷近因效应。这些数据与来自纯粹形式的语音短期记忆障碍患者的实验证据结合在一起[35]，得出双重神经心理学分离，表明两种近因效应的不同起源：短期记忆输出是在立即回忆范式中增强对终端项目的回忆的基础，以及在延迟近因效应的根源上应用于长期记忆存储单元的顺序检索策略。
This study was devised to investigate immediate and delayed recency effects in anterograde amnesic patients. For this purpose, a word-list immediate recall paradigm and a modified version of the procedure devised by Baddeley and Hitch [Attention and Performance, Erlbaum, NJ, 1977] for eliciting the recency effect in delayed recall conditions was administered to a sample of amnesic patients and to a group of age-matched healthy subjects. Amnesics disclosed a fully normal recency effect in the immediate recall paradigm and a deficient recency effect in the delayed recall condition. These data, taken together with experimental evidence from a patient affected by a pure form of phonological short-term memory impairment [35], draw a double neuropsychological dissociation suggesting a differential origin for the two kinds of recency effects: a short-term memory output underlying enhanced recall of terminal items in immediate recall paradigms, and an ordinal retrieval strategy applied to long-term memory stored units at the root of the delayed recency effect.
