Belief-biased representations of textual information in bilinguals: Language as a source characteristic

When pursuing a controversial socio-scientific issue, readers are expected to construct balanced representations that include overlapping and opposing information. However, readers' mental representations are often biased towards their prior beliefs. Previous research on such text-belief consistency effects have been conducted mostly in monolingual contexts. The present study investigated whether document language, as a source characteristic, moderates text-belief consistency effects at the situation-model and text-base representation levels. Eighty-seven bilingual readers-selected from a larger initial sample-read two documents on the global spread of English. The documents were either presented in participants' first (Persian) and second (English) languages, or one was presented in Persian and the other one in English. A recognition task was used to assess situation-model strength and text-base strength. Overall, participants built stronger situation models for the belief-consistent information as opposed to belief-inconsistent information. However, document language moderated the text-belief consistency effect. When both texts were presented in English, the text-belief consistency effect was smaller than when both texts were presented in Persian. For the combination of English and Persian texts, the text-belief consistency effect was enlarged when the belief-consistent text was presented in English and the belief-inconsistent text in Persian but disappeared when the text-belief consistent text was presented in Persian and the belief-inconsistent text in English. These results suggest that document language can serve as a strong credibility cue that can eliminate belief effects, at least when the document language and the controversial issue are inherently related.

Automated summary

This study investigated the moderating effect of document language on text-belief consistency effects. The results showed that document language can moderate this effect, especially when the document language is related to the controversial issue.
