Regression analyses of event-related brain potentials dissociate general reading experience and domain-specific knowledge sources during language comprehension.

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
How do different sources of knowledge and experience shape how we make meaning from language in real time? The present work capitalizes on recent advances in ERP analysis (the regression ERP, or rERP approach, combined with AIC model comparison to compare how various measures of knowledge and experience related to millisecond-by-millisecond ERP time-course data recorded as individuals read sentences about a fictional world (Harry Potter; HP) one word at a time. Participants were individuals who ranged in the experiences they had contributing to their HP knowledge, including the number of times they had read each book and/or seen each movie. These participants also completed an objective measure of domain knowledge using a short trivia quiz, as well as more general measures of reading experience. HP-based measures out-performed general reading experience for multiple indices of word understanding. Notably, self-reported experience with HP movie-watching best explained N400 "related anomaly" effects, which reflect the immediate availability of linguistically inappropriate but event-related words. Thus, the rich multimodal experiences of watching movies may, at least in some cases, accelerate knowledge use during language understanding compared to purely linguistic experiences of reading. These findings run counter to theories on which meaning is based on linguistic experience alone, implicating multimodal contributions. More generally, these analyses illustrate how exploratory model set comparisons and continuous variable rERPs yield new insights into the time course of information processing during reading.
