Current Projects

The two main lines of research in the Bilingual Cognition Lab are detailed below. However, we have conducted studies on a number of other topics related to bilingualism and/or human memory.

Funding Sources

Funded 2001-2005 by NIH grant 1 R15 MH61765-01A1
Funded 2006-2008 by NSF ADVANCE Research Assistantship
Funded 2016-2020 by NSF grant BCS-1632283 

Past Goals of the Project

(1) Develop a model of implicit memory
(2) Quantitatively specify transfer-appropriate processing 
(3) Understand conceptual overlap and transfer of learning across languages
(4) Understand bilingual vocabulary access
(5) Understand the learning that occurs with repeated exposures to bilingual vocabulary
(6) Evaluate whether the learning observed in repetition priming occurs in contextualized language

Current Goals of the Project

(1) Evaluate the degree to which comprehension exposures impact later production and for how long
(2) Determine the loci of word frequency and language proficiency effects on word production
(3) Determine whether modality-general representations are used for comprehension and production

Goals of the Project

(1) Determine which memory processes are impacted by bilingual language proficiency
(2) Discover the mechanisms underlying proficiency effects and monolingual-bilingual differences in memory performance
(3) Develop a theory to explain the effects of bilingualism and language proficiency on memory performance
