| Popis: | Extent of lateralization measurements have previously been performed for various stimulus types, mainly using two measurement paradigms: (1) an acoustic pointer paradigm where the interaural level difference of a pointer stimulus is adjusted to match the intracranial position of a target stimulus and (2) a visual pointer paradigm where the intracranial position of a target stimulus is indicated on a linear scale. Both measurement paradigms are widely used, but rarely within the same study. In this study, the extent of lateralization elicited by unfiltered as well as 4 kHz bandpass-filtered click trains carrying interaural time differences (ITDs) up to 3 ms was measured using an acoustic as well as a visual pointer paradigm. Data from six young normal-hearing listeners were compared. Using the visual pointer paradigm, the extent of lateralization behavior as a function of stimulus ITD for unfiltered as well as bandpass filtered click trains coincided. The extent of lateralization as determined by the acous... |
