ACADEMIC FIELD & RESEARCH
I conduct experimental-psychological and comparative-behavioral research with a particular interest in infant and child development, focusing on the species-specific communication in humans, as well as its mental foundations. I aim to reconsider and consolidate the theories of “Theory of Mind” concept theoretically as I adopt empirical approaches to the interactive process between biological bases and the cultural learning processes.
