Naqi successfully defended his PhD dissertation

December 18th, 2019

Naqi Defense Dec2019 14Naqi Defense Dec2019 13

Today on December 18th, Naqi defended his PhD dissertation. Naqi's research focuses on the extent to which relationships between emotional experiences and aggressive behaviours in adolescents are affected by culture. He found that the traditional classification between individualistic Western countries and collectivistic Eastern countries was not fully supported when cultural values were assessed at individual levels, which may have important implications for future cross-cultural research and interventions.

Congratulations, Dr. Naqi!


What is fair? Fairness decisions in adolescents; the effect of hearing loss

November 15th, 2019

coins stacking

A sense of fairness is assumed to be innate, but is it? Adva examined fairness in deaf / hard-of-hearing (DHH) and hearing adolescents, presenting the participants with different situations to distribute coins between a peer and oneself. Although young DHH adolescents had more difficulties than their hearing peers to live up to the equity principle when it would cost their peer a coin, older DHH participants had more difficulties with equity when this implied less coins for themselves. The paper is available open access in Social Development. Click here to read it.

Who are we?

FOE group 2019 crop

Our team is located at the department of Developmental Psychology of Leiden University in the Netherlands. We work in close collaboration with the Dutch Foundation for the Deaf and Hard of Hearing Child (NSDSK), the ENT department of the Leiden University Medical Centre (LUMC), the Centre for Autism, the Leiden Institute of Advanced Computer Science (LIACS), TU Delft, and University of Twente. Our group is dedicated to examining the emotional development of children and adolescents of all walks of life. We have a strong focus on the functionality of emotions, and its impact on children's social development. Besides typically developing children and adolescents, we are interested in the development of those who are deaf or hard-of-hearing, with autism spectrum disorders, or with specific language impairments.

On this site we regularly post news items about new publications, events, and so on. You can also read more about our ongoing projects, read about and download questionnaires we have developed,
