Our research team (MultiLADA) consists of employees and doctoral students of the Department of Cognitive Psychology and Neurocognitive Science at the University of Warsaw.


In research projects that we are currently conducting, we cooperate with researchers from Polish institutions: the Institute of Psychology of the Polish Academy of Sciences and the University of Finance and Management in Warsaw, as well as Norwegian institutions: Oslo Metropolitan University (OsloMet), Universitetet i Oslo, Inland Norway University of Applied Sciences, and British institutions: Lancaster University, University of Cambridge. We also have experience in cooperation in international COST networking programs: A33, IS0804, IS1306, IS1406. International cooperation is important for our team because studies of bi- and multilingual language development should include both languages of the child and the two languages should be analyzed in a similar manner. We co-created and still co-create various tools for assessing language in multilingual children: LITMUS-CLT, LITMUS-SRep, LITMUS-MAIN. We use these tools in our own studies and lend them to other researchers for scientific purposes. We are currently carrying out two research projects with external funding: StarWords (NCN - OPUS programme) and PolkaNorski (NCN - GRIEG programme, financed by the Norway Grants). We also co-create Action II.3.7 "Multilingualism" under the strategic program of the University of Warsaw: Excellence Initiative - Research University and we participate in another strategic program of the University of Warsaw: Alliance 4EU+, under which we participate in the European Network for Psycholinguistic Research on Multilingualism and Multilingual Development.
