Exploring Social Worlds
Research Focus
Educational studies
My research primarily explored the personal and school-related factors that influence academic achievement and career choices. I have analyzed data from large-scale international educational studies such as PISA, TIMSS, PIAAC, and PIRLS. Additionally, I have investigated the development of academic self-concept and academic motivation, and I am especially interested in how social comparison affects academic achievement and motivation (e.g., upward comparison, Big-Fish-Little-Pond Effect, and relative deprivation).
Cognitive psychology
In the field of cognitive psychology, my work focused on the development of numerical cognition, with a particular interest in studying the mechanisms of nonsymbolic numerosity representations. I published several papers focused on investigation of mechanisms of functioning the Approximate Number System and its development.
Psychometrics
In psychometrics, my experience includes developing and adapting instruments to investigate personal characteristics such as grit, academic motivation, and self-concept. Additionally, I led a research group called "Cognitive Psychometrics" for two years, where we explored the historical relationship between psychometrics and cognitive studies, as well as the challenges of reliably measuring individual differences in cognitive research.
