Natural language syntax

Natural language syntax yields an unbounded array of hierarchically structured expressions. We claim that these are used in the service of active inference in accord with the free-energy principle (FEP). While conceptual advances alongside modelling and simulation work have attempted to connect speech segmentation and linguistic communication with the FEP, we extend this program to the underlying computations responsible for generating elementary syntactic objects. We argue that recently proposed principles of economy in language design—such as “minimal search” and “least effort” criteria from theoretical syntax—adhere to the FEP. This permits a greater degree of explanatory power to the FEP—with respect to higher language functions—and presents linguists with a grounding in first principles of notions pertaining to computability. More generally, we explore the possibility of migrating certain topics in linguistics over to the domain of fields that investigate the FEP, such as complex polysemy. We aim to align concerns of linguists with the normative model for organic self-organisation associated with the FEP, marshalling evidence from theoretical linguistics and psycholinguistics to ground core principles of efficient syntactic computation within active inference.

Natural Language Syntax

abstractNatural language syntax has previously been thought to reflect abstract processing rules independent of meaning construction. However, grammatical categories may serve a functional role by allocating attention towards recurrent topics in discourse. Here, we show that listeners incorporate grammatical category into imagery when producing stick figure drawings from heard sentences, supporting the latter view. Participants listened to sentences with transitive verbs that independently varied whether a male or a female character (1) was mentioned first, (2) was the agent or recipient of an action, and (3) was the grammatical subject or object of the sentence. Replicating previous findings, we show that the first named character as well as the agent of the sentence tends to be drawn to the left in the image, probably reflecting left-to-right reading direction. But we also find that the grammatical subject of the sentence has a propensity to be drawn to the left of the object. We interpret this to suggest that grammatical category carries discursive meaning as an attention allocator. Our findings also highlight how language influences processes hitherto thought to be non-linguistic.
