Abstract:
Human language is compositional; language users create unbounded and novel phrases and sentences from a finite number of words. This compositional ability is highly structured; words must be combined according to syntactic rules to yield well-formed and interpretable phrases and sentences. Although many studies have provided neural evidence for when and where compositional processing takes place, how it is actually implemented in neural circuits remains largely underspecified. My research investigates the role of low-frequency neural activity in carrying out composition. In this talk, I will discuss the functional interpretation of delta-band frequencies (<4 Hertz), the temporal constraints of information processing in low-frequency neural activity, and the reconciliation between active segmentation and the processing of complex structures. Several ongoing projects and future directions will be discussed.
