2 Effects of music therapy for adult CI users on the perception of music, prosody in speech, subjective self-concept and psychophysiological arousal Slide: 2 German Center for Music Therapy Research Effects of music therapy for adult CI users on the perception of music, prosody in speech, subjective self-concept and psychophysiological arousal Objectives: Evaluating effects of music therapy on perception of musical parameters and subjective sound quality Additional effects? à Detection of prosody in speech à Subjective self-concept à Psychophysiological arousal during hearing task

3 Effects of music therapy for adult CI users on the perception of music, prosody in speech, subjective self-concept and psychophysiological arousal Slide: 3 Contents of Music Therapy Module Therapy goal Variability of voice and speech Improving speech comprehension and production especially on emotional speech prosody The diverse components of music Training the perception of discrete musical components such as pitch, rhythm and timbre Playfully used components of speech Improving speech comprehension by means of spontaneous and easy manipulation of verbal contents and gradually reducing lip reading Speech in diverse hearing surroundings Training the selective hearing of linguistic contents and information e.g. when combining musical and linguistic features Complex hearing Improving the selective filtering of important stimuli within complex auditory surroundings

4 Effects of music therapy for adult CI users on the perception of music, prosody in speech, subjective self-concept and psychophysiological arousal Slide: 4 Methods Subjective sound quality (HISQUI) Subjective self-concept (MSCS) Musical tests (pitch, timbre) Detection of prosody in speech Psychophysiological arousal (skin conductance level, pulse rate) during hearing task

5 Design Therapy group (n = 10): 10 sessions of therapy Implantation Initial Activation of Speech Processor Diagnostic assessments: Questionnaires Musical tests Psychophysiological assessments Care as usual Waiting goup (n = 10): Care as usual Diagnostic assessments: Questionnaires Musical tests Psychophysiological assessments Period of deafness (years) Time elapsed: IA diagn. 1 (days) Time elapsed: diagn. 1 diagn. 2 (days) Therapy group (M [SD]) 10.0 (11.84) (158.3) (19.5) 40% Waiting group (M[SD]) 4.70 (5.53) (122.6) (10.6) 40% t-test p-value Musical activity (percentage) Control group n = 25 Musical tests Psychophysiological assessments Effects of music therapy for adult CI users on the perception of music, prosody in speech, subjective self-concept and psychophysiological arousal Slide: 5
