Problems in social functioning are frequently noted in the literature with respect to deaf or hard-of-hearing children. Yet, their emotional development is a severely understudied area, even though an impaired emotional development is likely one of the underlying factors for problems in the social domain. Within our lab multiple research projects are being conducted aimed at studying various aspects of social-emotional development, and involving different age groups. These projects are conducted in close collaboration with the ENT department of the LUMC and with the NSDSK.
Outcomes of the various projects listed below are published in (inter)national journals. See our list of publications on deafness.
Deaf and hard-of-hearing children often experience difficulties concerning their theory of mind development. To date, most of the studies reporting this outcome were conducted with children age four or over. Yet, eye tracking makes it possible to assess children's socio-cognitive skills at a much earlier age. This technology provides the opportunity to assess whether deaf and hard-of-hearing children aready show impaired theory of mind in infancy or whether this develops later on as a result of impaired communication.
Besides theory of mind, we also study early moral development by examining whether deaf and hard-hearing infants differ from their hearing peers concerning their sense of fairness. In addition, we examine if and how early parent-child interaction is associated with infants' socio-cognitive abilities.

In order to interact with others properly, you need to be able to control your emotions. This involves the ability to acknowledge your own emotions and to know how to communicate these most effectively. For deaf and hard-of-hearing children this seems to be problematic but the origins of this lack of emotion control are unclear. Are these children more easliy aroused than their hearing peers? Do they lack insight into the communicative function of emotions? By using mood induction techniques and by varying the salience of a goal (i.e., reaching a personal or a social goal) we aim to study the origins of emotion control.

Most deaf and severely hard-of-hearing children nowadays receive a cochlear implant. The literature has clearly proven that cochlear implants benefit children's language development. But what about its effect on social-emotional development? In a longitudinal study, multiple components of social-emotional functioning are examined in a sample of 1- to 5-year-old children with cochlear implants. Results thus far show that children with cochlear implants behave just as empathically towards others as hearing children. Yet, they fall behind on understanding others' emotions, theory of mind and moral development. We are currently examining how early (impairments in) emotional skills relate to later social functioning and psychopathology.

Deaf and hard-of-hearing children are known to more often experience social difficulties and are at higher risk for psychopathology. This research aims to address which aspects of emotional functioning contribute to social development and to (symptoms of) psychopathology. In a longitudinal study, a group of 9- to 15-year-old deaf and hard-of-hearing children is compared to a group of hearing peers. Results thus far confirm that deaf and hard-hearing children experience higher leveld of anxiety and depression.

The project Hoe laat ik mijn wereld zien? (i.e., How do I show my world?) is a collaboration of our research group with trainer Ivet Pieper and the NSDSK. In this project, we develop a methodology to strengthen deaf and hard-of-hearing children's capacities by using participatory video methods (PV). PV strengthens children's capacity for emotional self-reflection and may have positive effects on their social and emotional development. The children who participate in this project learn how to create videos about their school, the classes they attend or the friends they play with. Through video, these children will become more aware of their own behaviour, how they present themselves, and the effect this has on others.

Lecture in Birmingham
On 9 January 2017, Evelien Broekhof gave a lecture for a Hearing Impairment programme at the University of Birmingham, UK. The programme is designed for teachers of the deaf. Evelien's session, Learning emotions in children and adolescents with hearing loss, focused on the emotional competence in DHH group. The lecture was very well-received. In the picture, Evelien is with programme leader Dr. Emmanouela Terlektsi (right) and co-coordinator Angela Wootten (left).
Paper Published: Empathy in Toddlers with Moderate Hearing Loss
Our latest findings on empathy in toddlers with moderate hearing loss have recently been published by the Journal of Deaf Studies and Deaf Education! The study was done by Evelien Dirks, Lizet Ketelaar, Rosanne van der Zee, Anouk Netten, Johan Frijns, and Carolien, and was a collaboration between our lab at Leiden University, the University Hospital (LUMC), and Dutch Foundation for the Deaf and Hard of Hearing Child (NSDSK). The results show that toddlers with moderate hearing loss and with hearing have similar levels of affective empathy, yet toddlers with moderate hearing loss lag behind on some precursors of cognitive empathy, such as intention understanding and joint attention. It suggests that toddlers with moderate hearing loss are at risk for problems in their empathy development. Although they are aware of other people's emotions, they show a delayed development of more complex skills required for an adequate empathic response in comparison with their hearing peers.
Discussion on DHH children at NSDSK
On 28 November 2016, our lab members who are currently working on deaf and hard-of-hearing (DHH) children (Carolien, Boya, Evelien, Brenda, Tirza, and Yung-Ting) had a meeting with NSDSK in Amsterdam. The two parties shared the projects they are doing and planning to do, and had a lively discussion on issues related to DHH children.
Royal Kentalis Knowledge Day
On November 25, Royal Kentalis organised their annual “knowledge day” for professionals working with children with a hearing loss, in their organization and collaborative organizations. While Carolien addressed adolescent’s friendship quality in a key note session in the morning, Evelien organized two master classes on the development of moral emotions and its impact on DHH adolescents’ social behaviors. Both classes were well-received and evoked the necessary discussions.
Lecture in Liverpool on social-emotional development of deaf children
On 21 October 2016, Lizet went to Liverpool to give a lecture about the social-emotional development of children with a hearing loss. At the annual Hallpike symposium, she informed the audience of audiovestibular physicians about our research outcomes. The talk was well received, raising awareness that these children might experience social-emotional difficulties and that parents ought to be informed about this topic during the cochlear implant decision-making process.
