    Sammanfattning : During the first year of life, infants go from perceiving speech sounds primarily based on their acoustic characteristics, to perceiving speech sounds as belonging to speech sound categories relevant in their native language(s). The transition is apparent in that very young infants typically discriminate both native and non-native speech sound contrasts, whereas older infants show better discrimination for native contrasts and worse or no discrimi­na­tion for non-native contrasts.

    Sammanfattning : In daily life, people need to be able to focus on a task while ignoring any task-irrelevant background noise. For example, people who work in an open-space office may have to work on a report while ignoring the background talk among co-workers. LÄS MER

  5. 4. Neurophysiological conditions for hearing in children using hearing aids or cochlear implants : an intervention and follow-up study

    Författare :Elisabet Engström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : OBJECTIVES: The four studies in this thesis examine the central auditory pathways in children with hearing loss (HL) through recording event-related potentials (ERP) and mismatch negativity (MMN). The design of the project is partly experimental, and it also includes an intervention part and a follow-up-study after three years. LÄS MER
