Einfluss kontinuierlich nachgeführter Peilbewegungen auf das intentionale Wechseln der auditiven selektiven Aufmerksamkeit
- Auditorische Szenenanalyse
Bachelorarbeit von Wepner, Saskia
Previously, the stimuli used in listening experiments for the investigation of auditory selective attention were reproduced statically -- i.e. without considering individual head movements of a test person. However, due to former experiments, there is reason to believe that a more realistic presentation of stimuli in auditory scenes might improve test persons' cognitive performance on sound localisation. An improvement of test results in terms of reaction time and error rates is already evocated by the modification of dichotic to binaural sound reproduction. Individual head movements play an important role for sound localisation in auditory scenes because they provide a faster and more precise classification of the presented stimuli. This work shall evaluate the benefit of more realistic auditory scenes by considering head movements in experiments on auditory selective attention (ASA). Thus, a part of this work is the implementation and realisation of a listening test to examine the given paradigm. The acoustic cues are adapted to the test person's head movements which are detected by means of a visual tracking system. Former findings suggest that performance in localisation improves through consideration of head movements in listening tests.
