Remember-know judgments can depend on how memory is tested.
Remember-know judgments reflect the subjective state of awareness that accompanies episodic memory retrieval. We tested an old-new recognition condition, an old-new recognition followed by remember-know judgment condition, and a simultaneous remember-know-new judgment condition. These three conditions were tested for both a short (1-sec) and a long (4.5-sec) study duration. Reassuringly, results from the first two conditions did not differ from each other. Results from the third condition, however, differed from those in the first two conditions at both long and short study durations. Simultaneous consideration of all three alternatives resulted in a markedly liberal response bias, both in recognition detection and in the ascriptions of remember and know judgments. Discussion of the results is framed in terms of the single-process signal detection models that have been proposed to account for these subjective states of awareness.
