Modeling Conventionalization and Predictability in Multi-Word Expressions at Brain-level

Linguistic expressions have been binarized as compositional and non-compositional given the lack of composionallinguistic analysis, Multi-word Expressions (MWEs) demonstrate finer-grained degrees of conventionalization and predictability in psycholinguisitcs, which canbe quantified through computational Association Measures, like Point-wise Mutual Information and Dice's Coefficient. In this study, fMRI recordings of naturalistic narrative comprehension is used to investigate to what extent these computational measures and the underlying cognitive processes they could reflect are observable during on-line naturalistic sentence processing.
