Déjà vu is beginning to be scientifically understood as a memory phenomenon. Despite recent scientific advances, a remaining puzzle is the purported association between déjà vu and feelings of premonition. Building on research showing that déjà vu can be driven by an unrecalled memory of a past experience that relates to the current situation, we sought evidence of memory-based predictive ability during déjà vu states. Déjà vu did not lead to above-chance ability to predict the next turn in a navigational path resembling a previously experienced but unrecalled path (although such resemblance increased reports of déjà vu). However, déjà vu states were accompanied by increased feelings of knowing the direction of the next turn. The results suggest that feelings of premonition during déjà vu occur and can be illusory. Metacognitive bias brought on by the state itself may explain the peculiar association between déjà vu and the feeling of premonition.
似曾相识感开始被科学地理解为一种记忆现象。尽管最近取得了科学进展，但一个未解之谜仍然是似曾相识感与预感之间据称存在的关联。基于研究表明，似曾相识感可能是由对过去经历的未被回忆的记忆驱动的，这种记忆与当前情况有关，我们试图在似曾相识感状态下寻找基于记忆的预测能力的证据。似曾相识感并没有导致在预测类似于以前经历但未被回忆的路径的导航路径的下一个转弯时具有超出机会的能力（尽管这种相似性增加了似曾相识感的报告）。然而，似曾相识感伴随着对下一个转弯方向的熟悉感增加。结果表明，似曾相识感期间的预感是存在的，可能是虚幻的。状态本身带来的元认知偏差可能解释了似曾相识感和预感之间的特殊关联。
