Language Acquisition


Dr. Dimitrios Skordos

Dr. Angeliki Athanasopoulou’s research focuses on prosodic development and prosodic typology, aiming to understand different aspects of prosodic systems across languages, both how they are structured and processed, and how they develop in children.

At the Developmental Psycholinguistics Lab we study how children between the ages of 2 and 12 years acquire their first language and how that interacts with other aspects of their cognitive development. We use a variety of behavioral tasks including eye-tracking to test children’s language production, perception, and comprehension. The lab houses three research groups. 

Phonological Development Group

PI: Angeliki Athanasopoulou (

Our group studies how children develop the sound system of their language, focusing on prosodic patterns larger than the word. Our studies are typically cross-linguistic investigations of children’s production and perception abilities. Other main topics of research is the information pre-linguistic children use at the very beginning to break into their language (bootstrapping theories) as well as the role of a changing input in language acquisition.

Semantic and Pragmatic Development Group

PI: Dimitrios Skordos (

Our main research question is how children learn the meanings of words and phrases in their language and how they use their language-learning abilities to think about and understand context and the intentions of others. Projects in the group include the acquisition of quantifiers and logical connectives as well as the acquisition of spatial terms and motion event and how that interacts with memory and non-linguistic cognition.”

Language and Cognitive Development Working Group

We are an interdisciplinary group of linguists and psychologists working on first language acquisition and cognitive development. We meet monthly to discuss current theories, challenges, and debates on these topics. If you are interested in joining our group, please contact Angeliki Athanasopoulou (

Second Language Acquisition

*This research group is not active currently.

PI: Dr. Susanne Carroll

Former members: Lindsay Hracs, Kelly Burkinshaw, Elias Abdollahnejad

One of the primary goals of our research is to learn more about how adult second language learners learn functional categories at the earliest stages of acquisition, i.e. on first exposure.  Much of the research done with real learners (as opposed to artificial language learning studies) is descriptive. Instead, we are controlling the stimuli and population of interest in such a way that we can make stronger claims about cause and effect in learning.
