One important aspect for language acquisition is the discrimination of different acoustic features, such as frequency information. Concerning SLI, studies to date that examined frequency discrimination abilities have been contradictory. We hypothesized that an auditory processing deficit in children with SLI depends on the frequency range and the difference between the tones used. Using a passive mismatch negativity (MMN)-design, 13 boys with SLI and 13 age- and IQ-matched controls (7–11 years) were tested with two sine tones of different frequency (700 Hz versus 750 Hz). Reversed hemispheric activity between groups indicated abnormal processing in SLI. In a second time window, MMN2 was absent for the children with SLI. It can therefore be assumed that a frequency discrimination deficit in children with SLI becomes particularly apparent for tones below 750 Hz and for a frequency difference of 50 Hz. This finding may have important implications for future research and integration of various research approaches.</dcterms:abstract> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2012-02-01T13:50:32Z</dc:date> <dc:creator>Schecker, Michael</dc:creator> <dcterms:bibliographicCitation>Publ. in: Neuroscience Letters ; 413 (2007), 2. - S. 99-104</dcterms:bibliographicCitation> <dc:creator>Schulz, Eberhard</dc:creator> <dc:contributor>Kohls, Gregor</dc:contributor> <dc:contributor>Maas, Verena</dc:contributor> <dc:creator>Rinker, Tanja</dc:creator> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103605204-4002607-1"/> <dc:rights>deposit-license</dc:rights> </rdf:Description> </rdf:RDF>
