Whereas both human and animal lesion and human neuroimaging studies have implicated the hippocampus in memory for associations, some studies find preserved associative memory following hippocampal damage. Starting with a classic summed similarity model of item recognition, we can account for associative recognition without assuming a specific hippocampally-mediated associative process. We add one key assumption: that one item can influence activation of another item's features. Feature-strength patterns, evaluated for each probe item individually, are then diagnostic of whether an item was paired with one item versus another. We suggest that feature-level inference, without explicit storage of associations, may play a critical role in associative recognition tasks.

尽管人类和动物损伤研究以及人类神经影像学研究都表明海马体与联想记忆有关，但一些研究发现海马体损伤后联想记忆仍得以保留。从经典的项目识别总和相似性模型出发，我们可以在不假设特定海马体介导的联想过程的情况下解释联想识别。我们添加了一个关键假设：一个项目可以影响另一个项目特征的激活。然后，针对每个探测项目单独评估的特征强度模式可用于诊断一个项目是与一个项目还是另一个项目配对。我们认为，在没有明确存储联想的情况下，特征级推理可能在联想识别任务中起关键作用。（PsycInfo数据库记录（c）2023美国心理学会，保留所有权利）
