Understanding how children with hearing loss interact

July 14, 2017

Brenda Johan Portugal

Starting with her PhD project in March, Brenda now works on the actual data collection in Portugal. The project, supervised in Portugal by Dr. Guida Veiga (University of Evora), in collaboration with two Portuguese hospitals (Hospital Lusíadas Lisboa, Dr. Luísa Monteiro and Hospital Dona Estefânia, Dr. Herédio Sousa), focuses on young children with a hearing loss and their social development. In the last week of May on the European Symposium on Paediatric Cochlear Implantation (ESPCI), Brenda and Prof. Johan Frijns met with our Portuguese collaborators, to discuss the progress of the Portuguese project.

Validation Emotion Awareness Questionnaire in Portuguese

June 29, 2017


In a nice collaboration between the University of Evora (Portugal) and Leiden, the Emotion Awareness Questionnaire (EAQ) is now also available in Portuguese (European Journal of Developmental Psychology). The recently published validation study strengthens the already encouraging findings from previous studies across various other countries and languages (e.g. Spanish, Italian, French). Taken together, the EAQ seems to make an important contribution when studying children and adolescents’ emotion awareness and associated mental health problems.

You can download the validation paper here (50 free e-prints available), and find the EAQ in different languages here.


How to keep on top of the increasing research output?

Meta analysis VU May2017

How to make sense of the expanding literature about certain hypotheses? Meta-analysis is an alternative to the narrative review of research studies that helps integrating and analyzing the outcomes of a large number of studies. During the last week of May, Boya, Evelien Broekhof, Naqi, Tirza and Yung-Ting attended the workshop on meta-analyses at VU Amsterdam, provided by Prof. dr. Brad Bushman. Besides his enthusiasm and individually tailored supervision, Brad provided invaluable tools and insights, giving the students hand-on experiences of conducting such analyses.



Who are we?

Group picture 2016 crop2

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), and the Centre for Autism.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 with hearing impairments, 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, see an overview of our publications per topic, or read about opportunities for students to join our team.






Welcome our new intern

Starting 3rd of July, Merve Aras (student at İstanbul Kemerburgaz University in Turkey) participates in our research lab under the supervision of Naqi and Carolien. During this internship, Merve will focus on the measurement of empathy in East-Asian countries. Merve is also eager to learn more about the Leiden traditions and visited a PhD defense in which Carolien acted as a committee member.

Social skills in preschool children with hearing loss

Hearing loss can lead to delayed development of social skills. However, this is mostly investigated in children with higher level of hearing loss; to what extent would unilateral or mild bilateral hearing loss (UMHL) affect the development of such skills? Nina Laugen examined this topic from Norway, and Carolien was involved from Leiden. They investigated the question by comparing between preschool children with UMHL, with moderate-to-severe hearing loss, and with normal hearing. The findings have just been published by Deafness & Education International. You can read the article here, or download the PDF directly here.

Peer feedback endorses prosocial behavior in adolescent boys with and without autism

Peers have been known as a powerful source of socialization. When children enter into adolescence, the influence of the peer group extends as it becomes a focus in the social world. However, so far the literature focused only on typically developing populations. It remains unclear whether and to what extent adolescents with autism are influenced by their peers. For better or for worse?
