Whether neural substrates underlying conflict resolution, or the ability to choose an appropriate response from number of alternate options, are shared across disparate domains is currently unclear. This thesis sought to extend previous studies examining this question by asking whether conflict adaptation occurs between Stroop (a non-syntactic task well-studied in the conflict resolution literature) and two different language tasks. Evidence for bidirectional behavioral interaction between processing of sentences with syntax-semantic conflict and Stroop was found in Experiment 1; however, there were no behavioral interactions between a multiword production task and Stroop in Experiment 2. The difference between these two studies could be consistent with either a domain-general or domain-specific model of conflict processing, as it is unclear whether interactions were not found due to differences in levels of conflict processing or differences in domains of conflict processing. Further research should focus on better distinguishing between these two possibilities. Finally, we also suggest that future research should better characterize the time course of conflict processing.
