Broad research topics @Psycholinguistics Lab
Language processing and communication -- We work on various aspects of language processing including lexical processing, sentence comprehension,
reading, and sentence production. We also probe how these mechanisms come together during naturalistic dialogue and how they interact with other aspects of
cognition (such as attention, memory, etc.). So far we have studied these topics in languages such as Bangla, Hindi and Malayalam. We are interested in extending
this work using languages from other language families such as Tibeto-Burman, and Austroasiatic. Here are some representative papers on [sentence comprehension],
[sentence production], [reading], and [naturalistic dialogue].
Grammar-Processor interaction -- Another research thread that we pursue is to understand if (and to what extent) language is shaped by processing pressures.
Broadly, we are interested in providing a functional explanation for the core design properties of language. Here we have investigated word order. Of particular
interest has been the rarity of crossing dependencies (or discontiguous phrases). Such word order configurations are interesting because they take natural languages
outside the scope of context-free grammars. [representative publication.]
Role of Cognitive Science in Education -- We are now beginning to investigate how insights from Cognitive Science and Psycholinguisitcs can help in learning
and pedagogy at the foundational level (ages 3-8) of education.
