My research covers developmental, cross-cultural, motivational, personality, and evolutionary life-span psychology. I employ qualitative and quantitative methodological approaches, including naturalistic observations, discourse analysis, experimental protocols, and quantitative statistical analyses as I strongly believe that we should be flexible in the choice of methods and that such a choice should be derived from research questions. My collaborators and I explained cultural variance by verifying a number of culture-independent relations between childhood context variables and implicit and explicit psychological measures in the preschool period as well as in adulthood. We identified specific relations between explicit and implicit developmental measures of self-regulatory and mentalistic abilities across cultures and universal developmental pathways in which childhood context variables are related to somatic and psychological development (see Chasiotis, 2011, 2018, in press).
