Two eye-tracking visual world experiments examined the effect of contrastive prosody (pitch expansion) and structural priming on the comprehension of an ambiguous branching structure in Japanese. In particular, we examined how contrast-evoking pitch expansion and structural priming interact with each other during online processing of globally ambiguous phrases such as mizuiro-no kaeru-no boosi 'blue-Gen frog-Gen cap'. Experiment 1 revealed that an effect of syntactic priming of the dispreferred RB analysis was enhanced by contrastive prosody which would support the primed structural interpretation. Experiment 2 showed that the contrastive pitch expansion which contradicts the contrastive relationship between the prime and target visual objects counteracted the LB priming, while it facilitated the RB priming. The results together demonstrated that prosodic cues interacted with syntactic priming both in an interfering and facilitatory manner.
