Auditive Verarbeitung und Wahrnehmung bei Jugendlichen mit Kommunikationsbeeinträchtigungen

Background In Germany, there are specialized vocational training units (BBW) for adolescents and young adults with special needs. The BBW Leipzig for people with disorders in hearing, language and communication registers a rising number of adolescents with auditory processing disorder (APD). However, test material to diagnose APD at this age is sparse. This study investigates auditory processing in adolescents with normal hearing but communication impairment with the available test material. Materials and methods 35 normal hearing adolescents (26 male, 9 female, mean age: 18.1 years) were included. All were trained at BBW Leipzig. Dichotic listening, understanding of speech in noise, accelerated speech, differentiation and analysis of phonemes were examined. In addition, non-verbal general intelligence, concentration, figural retentivity, and linguistic abilities were assessed. Results 25 participants showed conspicious results concerning APD; 5 had never been diagnosed with APD so far. In 9/25 adolescents, there was no hint of top-down disorders. These participants had problems in accessing auditory information and holding and manipulating information in working memory, although both linguistic and intellectual abilities were normal or even above average. Conclusions The study has shown that adolescents can be conspicuous according to the APD criteria of the DGPP and that an APD diagnosis from childhood is not necessarily already present. It also became clear that multi-professional diagnostics remains important beyond childhood. Standardized tests with corresponding age norms are needed.
