The effects of incidental learning and input frequency on the perception of non-native speech.
Article in Second language research, 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
The current study investigated the extent to which naive listeners could incidentally acquire non-native phonemic contrasts and the degree to which the frequency of exposure to the target phonemes affects their learning. A total of 100 English speakers were assigned to the following conditions: (1) 0-occurrence; (2) 2-occurrence; (3) 10-occurrence; (4) 20-occurrence; or (5) 30-occurrence. The participants watched a video that provided instruction on counting numbers in Korean while incidentally exposing them to various repetitions of the target phonemes. All participants completed a pretest, an immediate posttest, and a delayed posttest, each comprising an AX discrimination task. The effects of incidental exposure were found only in the 10-occurrence condition, in both the immediate posttest and the delayed posttest. While the current study demonstrates the overall efficacy of incidental exposure on the perception of non-native speech, it also highlights the important role that selective attention plays in language learning.
