Comparing recollection and nonrecollection memory states for recall of general knowledge: A nontrivial pursuit.

Based on the classic distinction between semantic and episodic memory, people answer general-knowledge questions by querying their semantic memory. And yet, an appeal of trivia games is the variety of memory experiences they arouse-including the recollection of episodic details. We report the first in-depth exploration of the memory states that arise for recalled answers to general-knowledge questions. In 2 experiments, participants classified their answers as learning memory or related memory forms of recollection, as feels familiar or just know forms of nonrecollection, or as a guess. A recollection state was reported for nearly half of the correct answers. Learning memory, related memory, and just know states showed similarly high accuracy and confidence-whereas the feels familiar state was much lower. The differences between familiarity and knowing highlight the importance of distinguishing these oft-conflated states. Our study establishes that episodic memory often contributes to retrieval of general-knowledge, and that the memory states arising during retrieval can be diagnostic of accuracy.
