Document language moderates the text-belief consistency effect.

When researching socioscientific topics, particularly on the Internet, readers face multiple texts that they must integrate into a coherent mental model. Previous research in monolingual settings has found that comprehension is biased toward readers' prior beliefs (text-belief consistency effect). Considering that the Internet is multilingual, this experiment focused on the influence of document language on the text-belief consistency effect. Assuming differences in epistemic prestige among languages, we hypothesized that document language would act as a credibility cue and moderate the text-belief consistency effect. Seventy-four German university students read two conflicting texts either in their L2 English (higher epistemic prestige) or in their L1 German (lower epistemic prestige). Participants constructed stronger situation models for the belief-consistent text than for the belief-inconsistent text only when they read the texts in German. These results indicate that document language can act as a source characteristic that may reduce belief biases in comprehension. [ABSTRACT FROM AUTHOR]
