Misleading Bias-Driven Expectations in Referential Processing and the Facilitative Role of Contrastive Accent.

Probabilistic preferences are often facilitative in language processing and may assist in discourse prediction. However, occasionally these sources of information may lead to inaccurate expectations. The current study investigated a test case of this scenario. An eye-tracking experiment examined the interpretation of ambiguous personal pronouns in the context of implicit causality biases. We tested whether reference resolution may be facilitated online by contrastive accent in cases of a bias-inconsistent referent. Implicit causality biases directed looks to the biased noun phrase; however, when the name of the bias-inconsistent antecedent was accented (e.g., JOHN envied Bill because he ...), this tendency was modulated. Contrastive accent seems to dampen the occasionally confusing prediction of implicit causality biases in referential processing. This demonstrates one way in which the spoken language comprehension system copes with occasional misguidance of otherwise helpful probabilistic information.
