The relationship between recognition and pattern discrimination is not fully understood, and research on the relationships between these two processes is sparse. It has been generally assumed that pattern separation allows for recollection-based recognition. However, recent research has called this assumption into question. Therefore, the need for more research on this topic is evident. In the present study, we sought to investigate relationships between recollection- and familiarity-based recognition and behavioural pattern separation in healthy young adults. Participants ( = 146) completed two recognition tasks on a computer. The first was a word-pair recognition task involving unrelated and unitised word pairs (designed to measure recollection and familiarity, respectively), and the second was a mnemonic similarity test involving old, new, and similar (lure) object images (designed to measure behavioural pattern separation and completion). Correlation analyses showed that both recollection- and familiarity-based recognition were positively related to behavioural pattern separation. Regression analyses showed that, while controlling for familiarity, behavioural pattern separation was still predictive of recollection. However, while controlling for recollection, behavioural pattern separation was no longer predictive of familiarity. These findings support theoretical assumptions linking pattern separation to recollection.
识别与模式辨别之间的关系尚未完全阐明，针对这两个过程之间关系的研究也较为匮乏。人们普遍认为，模式分离可以支持基于回忆的识别。然而，最近的研究对这一假设提出了质疑。因此，显然需要对此主题开展更多研究。在本研究中，我们旨在探究健康年轻成年人中基于回忆和熟悉度的识别与行为模式分离之间的关系。参与者（n=146）在计算机上完成了两个识别任务。第一个任务是一个单词对识别任务，涉及不相关和单元化的单词对（旨在分别测量回忆和熟悉度），第二个任务是记忆相似性测试，涉及旧的、新的和相似的（诱饵）物体图像（旨在测量行为模式分离和完成）。相关分析表明，基于回忆和熟悉度的识别均与行为模式分离呈正相关。回归分析表明，在控制熟悉度的情况下，行为模式分离仍然可以预测回忆。然而，在控制回忆的情况下，行为模式分离不再可以预测熟悉度。这些发现支持了将模式分离与回忆联系起来的理论假设。
