Linking Neuroimaging with Functional Linguistic Analysis to Understand Processes of Successful Communication.

Functional linguistic models posit a systematic link between language FORM and the FUNCTIONS for which language is used. This is a systematic (and therefore quantifiable) relationship. Yet, many open questions remain about the mechanisms that link form, function and communication relevant outcomes. Neuroimaging methods can provide insight into such processes that are not apparent from other methods. We argue that the combination of neural and linguistic measures will allow insight into both individual and population-level communication processes that would not be possible using either method in isolation. We present examples illustrating this methodological integration and notes regarding the most amenable linguistic tools. We summarize a framework in which language presented to and produced by participants undergoing neuroimaging is correlated with the resulting neural data and other proximal communication outcomes allowing the triangulation of individual experimental with population level outcomes, thereby linking between micro and macro levels of analysis.
