Neural Correlates of Coherence-Break Detection During Reading of Narratives

Abstract

This functional magnetic resonance imaging study examined the neural correlates of coherence-break detection during reading in the context of a contradiction paradigm. Young adults (N = 31, ages 19–27) read short narratives (half contained a break in coherence) that were presented sentence by sentence in a self-paced, slow event-related design. Reading times were longer for incoherent compared to coherent target sentences, and coherence-break detection was associated with activation in a large network of brain regions that were more active in response to incoherent than to coherent information. Some regions seemed exclusively associated with processing of incoherent information. In addition, activation in the precuneus was negatively correlated with working-memory capacity. Together, these findings shed light on the functional contributions of these brain regions to coherence-monitoring processes during reading and help bridge cognitive and neurobiological accounts of the cognitive processes involved in the construction of coherent mental representations of narrative texts.
