Stimuli presented on the fringe of awareness do not cause proactive interference.
Article in Neuroscience of consciousness, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A key question in consciousness studies is what is distinct about a conscious as opposed to a sub-conscious percept. The experiments presented here provide evidence for the hypothesis that only conscious percepts enable the formation of episodic memories. We do this by assessing proactive interference (PI) in rapid serial visual presentation (RSVP) streams. Specifically, in a post-stream recognition memory test, we quantify memory for items presented in the RSVP stream close in time to the memory test. PI is demonstrated if performance on long RSVP streams is worse than on short streams, where long streams have many more items presented before the item probed in the recognition memory test. We demonstrate PI on reaction times for slow streams [stimulus onset asynchrony (SOA) 350 ms], but not for fast streams (SOA 83 or 100 ms). We investigate the implications of this reaction time difference by fitting drift diffusion models. The failure to see PI in fast streams raises the possibility that stimuli presented below the threshold of awareness are not episodically encoded.
