Conversely, and in spite of its importance for everyday memory, the processes recruited during semantic retrieval are less well specified. We developed a semantic task analogous to single-item episodic recognition to interrogate semantic recognition receiver operating characteristics (ROCs) for a marker of a threshold retrieval process. We then fit observed ROC points to three signal detection models: two models typically used in episodic recognition (unequal variance and dual process signal detection models) and a novel dual process recollect-to-reject (DP-RR) signal detection model that allows a threshold recollection process to aid both target identification and lure rejection. Given the nature of most semantic questions used here, we anticipated the DP-RR model would best fit the data obtained from our semantic task. In Experiment 1 (506 participants), we found evidence for a threshold retrieval process in semantic memory, with overall best fits to the DP-RR model. In Experiment 2 (316 participants), we found within-subjects estimates of episodic and semantic threshold retrieval to be uncorrelated, suggesting the relationship between the analogous memory processes is not straightforward.
