OBJECTIVES In this study, procedures for measuring sound localization, sound lateralization, and binaural masking level differences (BMLDs) in young children were developed. Sensitivity for these tasks was assessed in large groups of children between 4 and 9 yr of age to investigate potential developmental trends. DESIGN Sound localization was measured in(More)
Bilateral cochlear implants (CIs) may offer deaf children a range of advantages compared to unilateral CIs. However, speech perception in noise is mainly facilitated by better-ear effects and much less by interaural comparisons or true 'binaural' hearing. Little is known about the development of the binaural auditory system with CIs provided at a young age.(More)
OBJECTIVE To investigate the additional bilateral benefits of a second cochlear implant (CI) in a group of young children (<6 years of age) and a group of older children (>6 years of age). METHOD This is a Belgian tertiary multi-centre study in which 33 CI-children with a second implant between the age of 2 and 12 participated. Assessments took place(More)
OBJECTIVE To examine the effects of sequential bilateral cochlear implantation (CI) on the life of young children after 36 months of bilateral implant use. METHOD Thirty-five children were assessed prior to and 3 until 36 months after activation of the second CI. Main outcome measures were: the Categories of Auditory Performance (CAP), Speech(More)
Practical experience and research reveal generic spoken language benefits after cochlear implantation. However, systematic research on specific language domains and error analyses are required to probe sub-skills. Moreover, the effect of predictive factors on distinct language domains is unknown. In this study, outcomes of 70 school-aged children with(More)
OBJECTIVES/HYPOTHESIS To evaluate the impact of a newborn hearing screening program on the management and outcome of deaf children and to identify underlying factors that may be responsible for the differences between high and low performing implanted children. STUDY DESIGN Retrospective cohort study of 391 implanted children in Flanders (Belgium). (More)
OBJECTIVES/HYPOTHESIS The objectives of this study were to examine the levels of anxiety in hearing-impaired children with hearing aids or cochlear implants compared to normally hearing children, and to identify individual variables that were associated with differences in the level of anxiety. STUDY DESIGN Large retrospective cohort study. METHODS(More)
OBJECTIVES To compare the preverbal communication skills of two groups of young implanted children: those with unilateral implantation and those with bilateral implantation. MATERIAL AND METHODS The study assessed 69 children: 42 unilaterally and 27 bilaterally implanted with age at implantation less than 3 years. The preverbal skills of these children(More)
Belgium, and especially the northern region called Flanders, has been a center of expertise in cochlear implants and early hearing screening for many years. Some of their surgeons and engineers were pioneers in the development of cochlear implants and in 1998 Flanders was the first region in Europe to implement a universal hearing screening program for all(More)
OBJECTIVES To compare preverbal behaviors of deaf children implanted under 1 year of age with age-matched hearing children. METHODS The study assessed 20 children; 10 deaf children implanted under 1 year of age and 10 normally hearing children of the same age. Preverbal skills were measured before, 6 months, and 1 year after implantation, using Tait Video(More)
