Keywords: spoken language processing, mental lexicon, word learning, spoken and visual word recognition, speech perception, phoneme categorization, non-native phonetic training, prediction.

Dr. Efthymia Kapnoula is a Staff Scientist at the BCBL. She holds a BA in Psychology and a MSc in Cognitive Science from the University of Athens. She received her PhD in Psychology from the University of Iowa in 2016.

Her research examines the mechanisms that underlie speech perception, spoken language comprehension, and word learning. Dr. Kapnoula's work has been formally acknowledged by her previous institution (D.C. Spriestersbach Dissertation Prize for best dissertation in Social Sciences, University of Iowa), but also more broadly in the field of cognitive psychology (ESCoP Early Career Publication Award, European Society for Cognitive Psychology).

In 2017 Dr. Kapnoula received a Juan de la Cierva-Formación Fellowship (Spanish Ministry of Economy, Industry & Competitiveness), in 2018 she was awarded a Marie Skłodowska-Curie Fellowship (European Commission), and in 2020 she was selected for an Ikerbasque Research Fellowship (Basque Foundation for Science).
